Empty Variables In Forms

Empty Fields In Forms
I'm working on a script for a form for people to submit their info ( Name, e-mail, AIM, website URL etc). Now it is possible that some people don't have AIM or a website. I'm using a html table to display the info on the member page and empty fields make the table look strange. Is there a way to set some default value (like N/A) that would be displayed in case a field is left empty?

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 And 4.21 (POST/GET)
With global variables set to on, I always had the following in my script to make sure variables had a default value:

if (empty($var)) {
$var = 1;}

Now with 4.21, I changed it to:

if (empty($_GET['var'])) {
$var = 1;}

The problem is sometimes I use GET and sometimes I use POST. With global variables on it didn't matter. Now it does. Is there a way to do this? When I try if (empty($_GET['var']) || empty($_POST['var'])), it doesn't work because one or the other will always be empty at any one time.

---

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.

Passing My Variables With Forms Variables
how to carry variables onto the next page along with the forms variables. I need to carry my own over too, but when I press submit on the form page only the forms variables carry over, not my own ?? I have two drop down menues on my form that provide two values "start & end" which I require to go with my own variables.I have tried "a href=" link which carries my variables but not the forms variables.

<?php
echo"<form method=get action=somepage.php?one=$one&two=$two&three=$three&four=$four>";?>
also tried
<a href=somepage.php?one=$one&two=$two&three=$three&four=$four&start=$start&end=$end

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.

---

Forms And URL Variables
I wanted to create a cool form processor for my site and I didn't want to use any JavaScript nor did I want to tell the user to use the back button!

What I did is have my script validate required fields, and if one of them is proven empty or something the script redirects the user using this code:
PRINT "<meta http-equiv='Refresh' content=&#390; URL=$url'>";

Now the $URL contains the variables like form.php?name=myname&email=myemail etc... using name=$name etc.. But I used this code to replace spaces with a "+" or the URL will be cut short and loose data: $name = str_replace (" ", "+", "$name");

And now for the fields in my form I have these little codes:
<? if (isset ($name))
print "$name";?>

I also went a step further and highlighted the tables that the empty field was in by changing the table background color! with this code:
IF (isset ($name) && ($name == "")) {
$name_color = "#CC0000";} else {
$name_color = "#FFFFFF";}

And of course the <? echo $name_color; ?> in the html... This works very well, I tested it in NS and IE my only concern is, is this a smart way of doing this? I mean using the URL to fill out the form so the user won't have to retype everything? Maybe their is a way or a better command than REFRESH? Does anyone know of the limit of characters that can be in the URL? I've tried up to 568 so far (Just testing for the heck of it). Any input on this method of form validation would be appreaciated

Posting Variables From Forms
With a form, I have two buttons.

One of them says:
- pay here

The other says
- pay somewhere else

Now, can I change the location to which the variables from the Form are
posted, depending on the button that they click? or am I always restricted
to the location specified in the action (e.g. <form method="post"
action="mynewpage.php">)

---

Session Variables And Forms
I have a mailing list manager script that allows viewing of subscribers and unsuscribers on several different mailing lists. I have a multi-selection drop down menu containing the names of the mailing lists. I want to change a session variable onchange() of the drop-down, so that the last query gets resent for the newly selected mailing lists(s) that the administrator is requesting to view.

Then I tried making the page reload() when the drop-down menu selections were changed, but I couldn't figure out how to retrieve the variables from the form considering I'm just reloading the page. I can't think of a good way to do this. So, basically, I am wanting to resend the last sent query changing only the mailing lists that I am searching.

PHP Not Getting Variables In HTML Forms
Just installed PHP, and Apache. Am having problems with the PHP to
get form data from an HTML file. Specifically, I can not obtain the
variable "tireqty" in a PHP file called by an HTML file. The files'
contents are listed as follow:

-----------------------------
The following is the HTML file
-----------------------------
<form action="processorder.php" method=post>
<table border=0>
<tr bgcolor=#cccccc>
<td width=150>Item</td>
<td width=15>Quantity</td>
</tr>
<tr>
<td>Tires</td>
<td align=center><input type="text" name="tireqty" size=3
maxlength=3></td>
</tr>
<tr>
<td colspan=2 align=center><input type=submit value="Submit
Order"></td>
</tr>
</table>
</form>
-----------------------------
The following is the PHP file 'processorder.php'
-----------------------------
<html>
<head>
<title>abcd</title>
</head>
<body>
<?
echo $tireqty." tires<br>";
?>
</body>
</html>
-----------------------------
I know PHP and Apache are working becasue I am able to to have an HTML
page to load a PHP page to do a for loop and use the "echo" function
to print the loop iterations. So I'm not sure why PHP can't access
the variable "tireqty". Is there some settings in the PHP engine that
I need to check for this?

Forms And Passing Variables
I am trying to use a PHP variable and pass it every time I call the page. The variable is $rn that should be a called randomly using rand() if the value of it is empty. However, the following code does not work.

if (isset($guess)) {
    $rn = rand(1, 100);
   }

The form in the page calls itself so it reloads and I am wondering how I pass this variable in the form each time and when the variable is sert to a value, not have rand() overwrite the value. Here is all my code:

Passing Variable Variables Through Forms
I´ve spent the last few hours trying to figure out why my code doesn´t work, cos I had it working already, then made a few changes which actually cannot have anything to do with my variables, and now just one of them is passed (strange, eh?).
OK, here´s the code ( a bit chaotic, I suppose, anyway...)

<FORM action="bestell_mail.php" method="post">
<?php
$namensliste = array(Name, Vorname, Strasse, Postleitzahl, Ort, Mail);
$laenge = array(12,12,12,5,12,20);

for($p=0; $p<6 ; $p++) {
//20
echo"<TR>
<TD nowrap>
{$namensliste[$p]}:
</TD>
<TD>
<INPUT TYPE=TEXT NAME={$namensliste[$p]} SIZE={$laenge[$p]} maxlength={$laenge[$p]} >
</TD>
</TR>";
}

?>
<TR>
<TD colspan=2 align=center>
<INPUT TYPE=submit NAME=submit VALUE=abschicken>
</FORM>

so actually, I should be able to use my variables, (the names of which I have in the array called $namensliste) in the file "bestell_mail.php".
I tried this using a loop to read the variable names from an array again, and I also tried it using simple code like this

echo "$Vorname";

I had it working already, as I mentioned before, so u can imagine this is driving me mad right now. So with ur help, maybe I can still get some peace of mind this night.

Passing Variables From HTML Forms
I'm using Apache 1.3.27 as a local host to develop my site offline, since I only have a 56k and cant be online all the time. The problem is that when I try to pass variables from a HTML form to a php file, it doesnt recognise the variable names here are the lines of code concerned: on the HTML form:

<input type="text" size="16" maxlength="20" name="email">

in the php file:

print ("Your email address is $email");

It works when hosted online, but not when offline i've turned global variables ON in php.ini, but that didnt help can anyone else suggest anything?

HTML Forms Sending Variables To PHP Scripts
I'm using some HTML script to post some variables (see attached HTML code) to a PHP script. When I click on the Submit button a 'File Download' window pops up and when I click on Ok it opens the php script that I'm calling in Notepad.

I'm new to PHP and Apache so is there something in the php.ini file that I may need to change? Or is it my code that needs altering?

Posting Multiple Variables To $_POST Using HTML Forms
This is my code :

<INPUT TYPE="HIDDEN" NAME="banner" VALUE="test">
<INPUT TYPE="SUBMIT" VALUE"3 DAYS">
</FORM>

Only the 1st Variable 'duration' gets passed!

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 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.

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'])) {

I'm I not seeing?

Help With Empty()
this is my php:

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

$pro5=addslashes($_POST['pro5']);

for ($i=1;$i==5;$i++){

Using If Empty
I am trying to use the if empty statment to make sure that every input box has been filled, the code looks like this. Code:

Empty If / Else ?
I have never done this, but I have an if/else statement, and if I don't want anything to happen in the if statement, should I leave it empty or is there something that I could add???

<?php
if(empty($_POST['fname'])){

}else{
     $name = $_POST['fname']
     mysql_query("INSERT INTO name(`first`) VALUES ('$name'));
}?>

How To Empty An Array?
I've got a nested array, which I populate while processing and formatting results from a query.

Is there a straight forward way to do this? I've tried re-declaring it but that doesn't empty it.

Sessions, Tmp Dir, Empty Files
Problem - the /tmp session files created in my tmp directory contain zero bytes (ie. totally empty). Any ideas why?

I've checked the file permissions on the tmp directory, and it's completely shared out. No error messages or logs are being generated that I'm aware of.

Thanks for any help...

Empty Arrays Or No Files
I have written a script which depending on the variable uploads $num files.
The value of $num is stored in a mysql column and each file is uploaded in an array $file[], then placed in a directory by the name $id_$i.jpg (for example).

The problem arises when I want to display the files back in a table. The $num is read back through the mysql query and if the amount of files is less than $num then I have a partially filled table. The cells with no filename display the icon which references "no image" as there is no file in the upload directory to reference.

What I would like to know is

1)if when the form is submitted and only half of the files are uploaded could I set the array so it realises that only half of $file[] has been filled, or that only 6 of 12 files have been uploaded.

2) Alternately, could I count the number of files in a directory on my server and store that value as an variable to set the number of columns in my table?

What would be the code for this???

Thanks in advance.

How Do I Not Print Something Out If A String Is Empty?
I am using mySQL to get stuff from a database, the fields are getting parsed into the variables $no , $t , $a , $l and $y

At the moment I am using this line this to display them to the web browser;

echo "$no: $t - $a [$l] ($y)<br>$n<br><br>";

However, sometimes $y is empty when the SQL query returns it's result and so if that happens I get something like

2000: blah - blah [whatever] ()
blah blah blah

Is it possible to add some code to my echo line that only outputs the () if $y is not empty?

I am sure this is possible but I havn't got a clue how to do it.

Empty Attachement Through Mail()
can someone check my code for me to see where I went wrong please?

I have made a short page where people can enter an email address and select a file to be sent to them. I have pillaged some code from some previous posts here which was very helpful. The script works more or less, however I have 2 problems:

1) The HTML isn't picked up in the body of the email, however the text is.

2) The attachment makes it to the email however when you open it up, its a blank file. The file name and size are correctly reported in the atachment.

Here is my code. I've also made sure the selected files are 777 on the server. If someone could take a quick gander, I'd really appreciate it!
