PHP :: Empty Variables And 4.21 (POST/GET)

Query About Empty POST Arrays
I started programming in PHP recently and have a query about empty
$_POST arrays. I can see two scenarios when this could happen.

1. When some tries to directly load the page to which data is being
posted (for example, opening www.foo.com/xyz.php directly when a form
action is xyz.php)
2. When the user clicks the submit button without entering anything.

I am aware that Javascript validation can take care of the second case,
but it's unreliable. What is the accepted way of handling the above
situations on the server side?
Do I just reload the calling page if the array is empty?

Dont Want To Post Data If Row Field Is Empty
I dont want to post the $row ['thumbnail'] data in this string if the field is empty. Can someone help me out? ....

Cannot Read Information From Form Using POST Or GET ($_Post Is Empty)
I am having problems in my php code. I am relatively new to php but I
know some basics.

This is the problem:

when i try to echo some information that is typed into form back to
the screen i get absolutely nothing. It seems like $_POST['name'] is
an empty string, along with $_POST and $_GET['name'].

I looked around to see if someone else had the same problem and found
that some people's code didn't work because of IE6. but i also tried
mine on Netscape and i got the same problem.

So why is $_POST empty after posting information. Even $_GET was
empty.

all of those returned empty

echo $_POST;
echo $_POST['name'];
echo $_GET['name'];

here is the code:
the code was originially meant to send an email but i commented the if
statement out to see why it wasn't working

<html>
<head><title>Feedback</title></head>
<body>

<?php

// Handle POST method.
//if ($_POST)
//{

$name = $_POST['name'];
$email = $_POST['email'];
$comments = $_POST['comments'];

// Compose simple text message:
$message = "Message from $name
($email)

Comments:

$comments";

// Send message to bob@microsoft.com
mail("email@email.com", "Feedback", $message);

PHP Variables Are Always Empty
I'm trying to write a PHP script which allows to enter an username and a
password and to click two buttons.
If I start my PHP scripts 'mytest.php' I see the two input fields and the
two buttons. However if I enter something to the input fields and press a
button the echo commands show nothing.

======

PHP script 'mytest.php'
-----------------------

<?php
session_start();

if (!isset($_SESSION['auth_ok'])) {
$_SESSION['auth_ok'] = false;
}

echo "$user <br>";
echo "$pass <br>";
echo "$button1 <br>";
echo "$button2 <br>";
echo "$auth_ok <br>";

if (isset($button1)){
echo "Button 1 has been pressed<br>";
$auth_ok = true;

Empty Variables In 4.2.1+
I have a site where I check to see if a variable isset to see which file I include on a page - the URL would be something like: http://www.domain.com/?s

Then in the PHP file I check to see: PHP Code:

Testing For Empty Variables
I am retreiving the results from a randomized multiple choice quiz sent from a another php page using:

foreach($_POST AS $field=>$value){

How do I check to see which questions were not checked?

Empty Variables In Forms
I have some functions that check to see if certain form variables are empty. If they are empty then the function returns a 0. All of that is working just fine. BUT, I cant get the script to see the 0. PHP Code:

Checking For Empty Variables
Can I use empty() to check to see if variables actually have data? Basically I want the script or something to check to see if there is data in the variables. If there is no data, give the user some instructions on writing some data (link to a form or admin panel). If there is data, then continue with writing to the database.

If(empty) Statements/session Variables
1. I have a 2 page form. When the user fills out the info on page form he is directed to the 2nd page of the form. A session variable has been created in the 2nd form to hold all the data from the 1st page. When the 2nd page is submitted all the data (stored from page 1 and new from page 2) are sent to the database.

2. Here is the problem. On page 1, I have several form fields (like combo boxes) that need to work together. For example: I have a text field (name=phylum) in which investigators add new phylum names which are eventually sent to database field "phylum" of the same name. Next to that is a select box (name=newphylum) that has all the names that the investigors have previously entered and that are dynamically retrieved from the database field "phylum".

So when a researcher fills out page 1 of the form he/she can either add a new name or select an already existing name from the select box. But just one of these values can be sent to the database, not both.

QUESTION 1: How can I say and where would I put something that basically says the following: if the phylum text field is left EMPTY (i.e. they don´t add a new name) and they select instead from the select box, that it is the value from the select box and not the text box that gets sent to the database.

QUESTION 2: How do I pass the statement from question 1 into the session variable on page 2 of my form?

Creating Empty Variables For Input Data
I am creating a script that will be taking data from a POST and submitting
the data to variables which are placed within a hash for string to data
association. Then, using HTML::Table and Mail::Sendmail, the data is parsed
into an html table and then an email is created and send to a recipient.
So, my question is this; How do I take the input from a post form and have
the variables pick up the data and process it into a hash?

my $name = ;
my $instock = ;
my describe = ;
# Hash to hold inventory data
my %table_data = (
model ='$modelnumber',
item ='$name',
available ='$instock',
description ='$describe',
);

This is all the code I have written thus far, any pointers or suggestions
for this project?

Firefox Causing Empty PHP Form Variables??
This is really weird, and I would never believe it possible if it
weren't actually happening to me.

I've a customer database in mySQL, using PHP to create the forms, yadda
yadda.
All of a sudden, every time I edit a customer, when I submit the form
using Firefox 1.0.2 on Linux (Fedora Core 3) it sends empty form fields
to the database.

BUT, if I use Firefox on Windows, or Opera on Fedora Core 3, it works
perfectly fine.

Any ideas what in the world could cause this?
Firefox on Linux worked fine to up until...the last few days I think.
The only think I can think of, is I may have installed a couple of
extensions during that time.

Can't See My Post Variables
I work on an application which runs on our Intranet network, so security it's not a big issue, and my phpinfo() get me register_globals on (php 4.1.2 on a Debian system).
The problems is that I can't see my post variables (only with $_POST) and I don't get it . Is there another setting wich overrides php.ini and stop my register_globals ->on to behave properly ?

With Variables And POST
On my online order form, I need to send a few variables to my
credit-card processor. These variables are for non-secure customer
comments, and will be sent through the usual metod, i.e.,
<form action="https://orderpage.ic3.com/hop/orderform.jsp"
method="post">

However, one variable is a text-area box for a detailed customer
comment, and this variable can get pretty long. But my credit-card
processor has a 256 byte maximum length limit for all POSTed
variables. However, I can add as many of these 256-byte variables as I
like.

So how can I accomplish this in the most simple, efficient, and
elegant manner? How can I break up the text-area vaiable into 256-byte
pieces and then send these variables via POST along with all of the
other form variables which will be POSTed through the usual HTML
means?

POST/GET Into Variables
how does this look? should this by me calling ... myforms = new
forms(); work by turning all key/value pairs for both get and post
into variable names of the same name as the get/post key, and the
variable values as the values from the post/get?

class forms {
// Some stuff
var $MyPosts;
var $MyGets;...

Post Cookie Variables
I have a page that include on the top the result of a cookie (i come form a previous page with some inputs) in the second part of the page a form with name surname email etc etc
On submit all the information (cookie + form) are sent by email...
my problem is this: in the email doesn't appear the cookie values
i try to create in the form tab a hidden fiel d with this value

<input name="NewEoc" type="hidden" value="<?php echo $COOKIE['NewEoc'] ?>">

Variables Past By Get And Post
I'd like a generic include that goes at the top of all pages that mysql escapes the variables past to the script. Is there a way to refer to the each of the variables past, for example (in pseudo code):

for(each $XX in (list of get/post variables)) {
$$XX = mysql_escape_string($$XX);
}

Processing GET And POST Variables
Below is a function adapted from one found in phpMyEdit.class.php
http://platon.sk/projects/release_l...hp?project_id=5
phpMyEdit is a form generator for PHP/MySQL.

I think this function works great, especially for forms where data is
redisplayed due to failed validation of user input. I wonder what the
opinion of other PHP users would be.

function get_cgi_var($name, $default_value = null)
{
// From the phpMyEdit project
// Usage: $name = get_cgi_var('name');
static $magic_quotes_gpc = null;
if ($magic_quotes_gpc === null) {
$magic_quotes_gpc = get_magic_quotes_gpc();
}
global $HTTP_GET_VARS;
$var = @$HTTP_GET_VARS[$name];
if (! isset($var)) {
global $HTTP_POST_VARS;
$var = @$HTTP_POST_VARS[$name];
}
if (isset($var)) {
if ($magic_quotes_gpc) {
if (is_array($var)) {
foreach (array_keys($var) as $key) {
$var[$key] = stripslashes(trim(strip_tags($var[$key])));
}
return $var;
} else {
$var = stripslashes(trim(strip_tags($var)));
}
}
} else {
$var = @$default_value;
}
return $var;
// If data is displayed/posted using htmlspecialchars($var)
// return @$HTTP_POST_VARS ? html_entity_decode($var, ENT_QUOTES) :
$var;
};

$name = get_cgi_var('name');

POST Variables And Sockets...
I have a server that uses Cpanel, and my mail server is Cpanel's cppop. I am trying to create an email address. With an older version of Cpanel, you could use this command line through sockets.

GET /frontend/x2/mail/doaddpop.html?email=emailaddress&domain=mysite.ca&password=emailpassword&quota=10 HTTP/1.0
Authorization: Basic $pass

That worked just fine because email addresses were created through GET variables. Now, they have changed it to POST variables. Now, I need to create an email address, while faking the following post variables:

email
domain
password
quota

I know I need to use sockets, and pass the POST variables, but I have no idea how to.

Passing Variables With POST
I have a file named login.php that basically just checks if a username and password are in a MySQL database. If they aren't then it shows access denied. If they are then I want to pass the $name and $pass to project.php in a different directory. Code:

Looping Thru POST Variables
I need to know how to loop thru the variables my script receives from a form with action=post. I need to build a list of only those variables that comes from my checkboxes.

POST Variables Not Coming Through
For some reason, at random posts, the post variables don't get thru to
the server. For example, if there is are two text fields: name and
email... (I have register_globals on)... When I try to update the
database with a query and use $name, $email, the $name is missing or
the $email is missing. I am building an intranet application and all
the 20 or so clients run IE. This happens very rarely. Something like
once in 100 updates.

But I can see this in the log files as update contact set name="",
email="asda@pol.com" where contact_id=918. Notice the name field is
blank. I have JS checks in the client side which does not allow blank
name field..

Is this an IE random error? How do I get over this?

POST Variables From Programs
we are trying to make a program in C++ that will comminicate with a PHP script. But we dont know how to get the variables from the program. We got it figured out with perl/CGI, but PHP seems to be a better way to connect to SQL server. On PHP the GET works, its easy, but it's not secure enough. I need informtion on what headers does the PHP require to get the POSTed data from a program.

Sending Variables As POST?
I am currently trying to send information to another page using the POST method. Unfortuantley I can not find any information on how to do this. Currently I am trying

Header ("Location: newpage.html?var=test&var2=test2");

Obviously this re-directs with the variables, but they are send using GET. Not what it need. Any ideas on how to post these variables to the new page?

Apache/PHP Post Variables
I'm working with someone on a PHP project. The other person is doing
testing of scripts on their personal machine using Apache as a web server.
The production server and the one I'm using are both using IIS.

This other person reports that in their PHP scripts when tested with Apache,
form variable sent via the POST method are not "coming through." (This is
even using the "long method" of specifying them as $HTTP_POST_VARS['x'].)
These same scripts work fine on the the IIS machine (the POST variable come
through).

I've looked online to see if I can find out if anything special must be
specified in the Apache configuration to enable the POST method, and
although I found other people posting similar problems, I saw no reference
to a solution.

Not Catching The Post Variables
For some reason my PHP script is not catching the post variables that should be being sent by this form. Code:

Forward POST-variables
I have a form which should be submitted with either of two actions. Tried with javascript but this seems unreliable. Now looking at php and a processor page as the action of the form (process.php) which then sends the user to the different actionpages...can't figure out how to forward the post-variables to the different pages. Code:

Post Variables From Header Redirect
I'm using header to redirect the browser to another page and in the url I've added ?var1=value1&var2=value2 to pass some argument as get to that script, can I pass in some way, arguments as post in this case ? may I do it in both methos at the same time ?

Passing Post Variables Using Fopen()
I'm trying to pull data from a website and read it into a file the I
can parse. I've done the before to site without post variables but I
can seem to get my statments to work with the post. Can someone help
me out?below is the code I have so far.

$url="www.somesitethatneedspostvariables.com";

$postdata = http_build_query(
array( 'postvarname1' ='value1',
'postvarname2' ='value2'
)
);
$opts = array('http' =>
array(
'method' ='POST',
'header' ='Content-type: application/x-www-form-
urlencoded',
'content' =$postdata
)
);

$context = stream_context_create($opts);
$file = @fopen($url, "r", $content) or die("Connection Error, Please
contact Webmaster ERROR CODE=0xDEADBEEF");

Get Unknown Number Of Variables From POST Or GET.
I am trying to create a page that redirects users to an advertiser's page. The reason for the redirect is statistics about who clicks where.

The situation is simple when I only need to redirect them to a page, but some of the ads on my site include forms which put data in either POST or GET and I need to know how to allow my redirect page to take that data from POST or GET, whatever that data is, and pass it on to the page that the data were intended for.

I think that once I get the data I can simply create a hidden form, on the redirect page, with the data from POST or GET already in it. However, I don't know how to get an arbitrary number of variables from POST or GET.

Search - Pass Variables Or Self Post
I've created a database of documents that is searchable by a variety of fields. Currently I have a PHP page called search.php with a form to get the keywords from the user and it then passes this back to itself, runs a query and displays the results. Doing it this way the address for the search page and the results of the search is the same.

This all works fine and I'm happy with it but I was wondering if it should be implemented differently where the keywords are used as a part of the address like with search engines with Google. I don't know what the advantages or disadvantages is for either method so I'm keen to hear what others think is the best method.

How Can I Pass Variables Via POST In A Script?
Let's assume we have a script that only accepts POST variable input.. How is it possible to pass variables to it (using a php-script)?

How To Loop Through POST Variables And Contents
I am looking for a standard way/function to loop through all POST variables
and their respective contents to update a database record.

Here's my ideal to pass a function and it update:
session variable - "ID" - that holds the record ID to update
$_POST or $HTTP_POST_VARS

The function would update the $_POST vaiables of the ID record with the
$_POST variable's contents.

Get/Post Variables Not Showing Under Windows
I'm quite rusty with PHP and have a little issue. A script transmit parameters to itself through a simple form. It works fine when I run it on aproduction server (Linux+Apache+PHP4). When I run the same script on my development machine (Win2K+Apache2+PHP5) the submited variables
don't show.

Here's some simplified code:

<HTML>
<BODY>

<?php
print_r ($_SERVER);
print_r ($submit);
switch ($submit) {
// ...
}
?>

<FORM METHOD=Get>Display content of:<BR>
<INPUT TYPE=submit NAME=submit VALUE=APACD1>
<INPUT TYPE=submit NAME=submit VALUE=APACD2>
// ...
</FORM>

</BODY>
</HTML>

Ftp_nlist Returns False For Empty Directory Instead Of Empty Array
In an application installed with PHP5 it looks like ftp_nlist() returns
false if the directory is empty, instead of an empty array as it should
according to the manual. On the original server with PHP4 it works as
expected.

Is this a bug, or an undocumented change in PHP5, or a setting that
could be changed somewhere?

PHP Not Populating Form Variables Passed Through POST Or GET
I"m running:

Windows Xp SP2
Apache2
PHP5
MySQL4

Everything seems fine and dandy, and I can do scripting on server side, but for some reason I cannot get data from a form to be put into a variable.

I have a simple form in an html page which submits, and in the php script that handles the input, none of the data in the form is going into the variables.

My php.ini file does have all the GPC's in place(ie variable_order, the way they get processed).

How To Process Some Variables, Then Place Them Into POST And Redirect?
I'd like to do the following in PHP. Is there a way?

Someone submits a form with data. I want to process the data, then once I'm done with it, take two of the variables, make them post variables and basically redirect the browser as if the user pressed the submit button with data filled in.

The variables can't appear in the url.

How Do You Parse Post Variables To A Popup Window?
I know this isnt really a php question but can anyone tell me how
you parse post variables to a popup window, here's my code so far, im
trying to pass the value entered into a radio button:

<head>
<script language="JavaScript" type="text/JavaScript">
var win= null;
function NewWindow(mypage,myname,w,h,scroll)
{
var winl = (screen.width-w)/2;
var wint = (screen.height-h)/2;
var settings ='height='+h+','
settings +='width='+w+','
settings +='top='+wint+','
settings +='left='+winl+','
settings +='scrollbars='+scroll+','
settings +='resizable=yes'
win=window.open(mypage,myname,settings);
if(parseInt(navigator.appVersion) >= 4){win.window.focus();}
}

</script>
</head>

<body>
<form name="answer" action="result.php" method="post">
<input type="radio" name="group1" value="Milk"> Milk<br>
<input type="radio" name="group1" value="Butter"> Butter<br>
<input type="radio" name="group1" value="Cheese"> Cheese<br>
<input type="submit" name="submit" value="submit" src="result.php"
onClick="NewWindow(this.src,'name',âÆ',âÆ','yes');retur n false" >
</form>
</body>

Post Variables After Java Sort Are Lost
I have an HTML table that is being constructed from a MySQL table and
displays a form that includes a check box on 1 of the fields on the form for
each record. I have included in this PHP program a javascript routine called
sorttable.js which is something I found on the internet for sorting tables
and works quite well. The HTML table includes a check box on each record so
the user can select certain records for passing to the next process. This
works fine unless I sort the table on some column and then the POST
variables are lost. When I run the following code there are no POST
variables that will echo except the submit button.

foreach ($_POST as $varName =$value){
echo ($varName . " = " . $value);
}

However, if I don't sort the table the POST variables will be echoed for
every record in the table. I'm not sure why this is happening or how to go
about solving it. When I check certain records on the form and then sort the
table the checks themself don't disappear only the POST variables do. This
prevents me from looping thru the ARRAY to determine the value of the POST
check box for each record to see if it was checked. If I run the above code
but don't sort it I will have several hundred POST variables (several for
each record).

Could someone give me an idea on how to solve this or offer some sort of
work-around?

Forward To Page Alongwith Variables In POST
How to forward a page to another page alongwith the parameters passed into it

I mean I have page a.php
which is called with some parameters in $_POST and I require to pass these to another page with same variables in $_POST

Passing Variables In Frame Page By Post Method
Is it possible to send variables by post method through a submit button to a frames page, and have all 3 pages in the frame pick up the variable using the $_request[var] ?In other words, I click on a submit button. in form action method call index.php the index page has a top, main, and a left frame.how do i get each one of those to receive the variable, when i can only sendit to one page? or is it possible to send it to more than one page, but only action to one page?

Problems With Error Checking / Control Of POST Variables
I have a small form that on button press submits to a PHP file for further
processing into a database. I have to change the script as it allows
blank / nothing to be submitted to the database. The intention is that if
any of the two form fields are blank (empty) then the page is resent
stating that they have to fill in all the fields to post (to a database).

If I deliberately leave the fields blank and submit the form, querying the
database shows that both fields are zero / null - so nothing was entered in
to the database.

However, if I use an echo command to see what is going on (before the data
is entered into a database) I get the $TheName field with a "1" and the
$TheComment field with an unknown entry (it doesn't echo anything to the
screen - but it's not empty).

The code I've used to test this is:

$TheName = $_POST[gbName];
$TheComment = $_POST[gbComment];

if (($TheName = NULL) or ($TheComment = NULL))
{
echo 'Quick error check running:<BR>'
echo "Name: $TheName<BR>";
echo "Comment: $TheComment";
exit;
}

This does NOT execute as these fields are not empty. It only runs if I
change to:

if (($TheName = !NULL) or ($TheComment = !NULL))

Which is pointless as it will always execute with genuine entries.

Using the amended code below:

if (($TheName = !NULL) or ($TheComment = !NULL))
{
echo 'Quick error check running:<BR>'
}

echo "Name: $TheName<BR>";
echo "Comment: $TheComment";

I get the result that both the echoed lines are displayed as blank (no
"1").

PHP:Unable To Post Variables From Html Form To Mysql Database
Plz dont treat this as another newbie query , i did my homework but
still getting nowhere :( :( :(

Trying to learn PHP on Fedora core 1 (PHP 4.3,MySQL,HTTPD).Unable to
post data from html form to php file(connecting to mysql database and
inserting into a table) .
This seemingly simple problem is making me go mad !!! I googled
extensively and already tried the following

I enabled " register_globals = On " .... in /etc/php.ini and
also took used _$POST syntax.

wot could be the problem .... is it the case that /etc/php.ini file is
not being read .... how do i know whether this is the default location
for php.ini?
Where can i find the PHPRC environment variable (the variable
responsible for the php.ini default location)

Is the problem something else .....?

Following is the code ...

form.html
---------
<HTML>
<HEAD>
<TITLE> email entry form </TITLE>
</HEAD>
<BODY>

<P>plz fil the form </P>

<FORM METHOD="POST" ACTON="form-handler.php">

NAME: <BR>
<INPUT TYPE=TEXT NAME="givename" SIZE=25> <BR>
AGE: <br>
<INPUT TYPE=TEXT NAME="givenaddress" SIZE=25> <BR>

<INPUT TYPE=SUBMIT>
</FORM>
</BODY>
</HTML>

form-handler.php

PHP Session Is Empty And Session File Is Empty
I am trying to save a SESSION variable which looks to succeed because right after I print it out to verify it. I do so as follows:

session_start();
<snip>
$_SESSION['security_code'] = $code;

The problem is that I submit a form on the same page and I need to check if the $_SESSION['security_code'] == $_POST['security_code'] however this condition is always false because $_SESSION['security_code'] is empty. I also checked the security files that are created in the PHP 'save_path' directory and it appears to be creating an empty session file.

Can anyone suggest anything here? Also prior to the condition, I also do a session_start() and that doesn't help either.

I got this code from a open source area and on that web site, if I test it it works fine. On my localhost it does not work. I'm not sure if I'm missing some configuration or whether PHP 5.2.2 has problems with sessions.

Post And Redirect With Post Data
The solution we have though up is the following:

1. The user fills in data in a form and hits submit
- This submits (POST) to another page (redirect.php)
2. redirect.php adds more POST data to POST and then submits all this POST data to another page (offsite [payment portal])

The reason why we have to do this is for someone who knows our to read html source code, could easily find the sucessful page which will then do the processing we need to do on our side. Which means freebeis.

Calling A Post Script From A Post Script; Curl Works But ...
I am trying to call a php script B from script A.

However, when I do this with curl everything works fine except the url of the script is the url of script A. How can I make the URL the URL of script B.

Is this possible with curl?

PHP Post, Then HTML Post?
Using PHP, I want to POST or GET some variables to a second php page.
This, I already know how to do.

However, on the second php page, I want to use a simple, standard HTML
form using the standard form-submitting method such as:

<form action="https://orderpage.ic3.com/hop/orderform.jsp"
method="post">

whereupon both sets of variables --- the earlier variables that were
POSTed or GETted to the second page, along with the standard form
variables derived within the second page --- will be POSTed to the
above URL.

In the second page, might I actually translate the received variables
into actual HTML code? For instance, if my first page POSTed the
variable xyz to the second page, then might the following code on the
second page receive that variable and then include it when the second
page's "Submit" button is pressed?

<? $xyz=$_POST['xyz']; ?>
<INPUT TYPE="HIDDEN" NAME="xyz" value="<?=$_POST['xyz']?>" >

Or how, otherwise, might this be done?

Using Empty And &&
Im checking to see if all of these are empty I have to do something:

if (empty($_POST['phhome'] && $_POST['phcell'] && $_POST['phwork'] &&
$_POST['email'])) {

But this isnt working and putting empty() around each didnt either. What
I'm I not seeing?

Help With Empty()
this is my php:

$pro1=addslashes($_POST['pro1']);
$pro2=addslashes($_POST['pro2']);
$pro3=addslashes($_POST['pro3']);
$pro4=addslashes($_POST['pro4']);
$pro5=addslashes($_POST['pro5']);

for ($i=1;$i==5;$i++){
if (!empty(${'pro'.$i}))
$pros.=${'pro'.$i}."";
}
echo nl2br($pros);

$pros return nothing, although $pro1 and $pro2 contain certain value...
