PHP :: Error In Page When Checking Http_get_vars("myvar") And "myvar" Was Not Passed In URL String

Preventing Visitors Ability To "re-visit" A Page Via The "back Button"..
I have a rather complex registration/member sign up form.. which gets a little confused, when a visitor "backs" completely out of the form, then for whatever reason returns to the form. The form contains 'cancel' buttons, which naturally cancel the reg process and redirects them to the document just before they started.

JS provides us with the "location.replace()" method, but I can't seem to find a way to coordinate the use of location.replace() with the posting of the form values. In short, I want to "replace" the first step of the form with the "second step".

I think what's making this tricky, is that each step of the form are located within the "same" page (register.php). The document works like so: The first step is the "Member Agreement" when they click "agree" (submit) the system creates a new row in the temporary register table of the db.

It then issues a registration cookie, which carries the row id, and session value. in addition (for those cookie impared users) we carry the row id and session value in hidden elements. So far, as long as the user continues through the process all is fine, but if they (for whatever reason) back all the way out, and click 'agree' again, the process fails.

I guess I have to find a way to force a reload of the 1st step "if they've gone back" OR "replace()" the first step with the second, so as to prevent the user from going "back" to the 1st step of the register page.

'Parse Error' Problem In "isset" And "empty"
I've been having some problems with a parse error that I can't figure
out (PHP 4.3.11 on Solaris9). Sample code:

<?php
// getting strange parse errors on this
class A {
var $value;
function A() {
$this->value = 1;
}

function getValue() {
return $this->value;
}
}

$a = new A();
if (!empty($a->getValue())) {
echo "success";
}
else {
echo "failure";
}
?>

The result of this is:

Parse error: parse error, unexpected '(', expecting ')' in
/foo/public_html/parse_errors.php on line 15

I also get the same effect with "isset", however, testing with "is_null"
or "is_int" produces the correct ("success"/"failure") result. Any ideas?

How Do I Do Something Like $color = ("red", "yellow", "blue")[$colornum]?
How do I take an index of a literal array, instead of a variable?

That is, say I want to get the short name of a month. Can I do
something like:

$monthname = ("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug",
"Sep", "Oct", "Nov", "Dec")[$month];

or do I always have to do:

$blah = array("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug",
"Sep", "Oct", "Nov", "Dec");
$monthname = $blah[$month];

It seems a shame to have to create a variable specifically for this
one-shot purpose.

Errors Won't Show Up Even With Error_reporting(E_ALL) And Ini_set("display_errors","1")
Here's my code:

<?php

error_reporting(E_ALL);
ini_set("display_startup_errors","1");
ini_set("display_errors","1");

wefw
wefwef=wefwe
2349023909()
;wrgwrg ====232

phpinfo(); ?>

I get a blank page.

If I take out the crap, it prints phpinfo() just fine.

Pagnation - Limit Number Of Pages Between "Previous" & "Next" Hyperlinks
Was hoping for some advice with a part of page navigation....

It works at the moment so there is a "Previous" & "Next" Hyperlink underneath the records. In between the Previous & Next links are the number of pages that there is of these records. e.g:

Previous 1234 Next

This is fine if there are only a few pages of records, but when there are hundreds of pages the numbers are listed and they take up half the web page with them.

How can i make it so only limited 10 numbers of pages say appear between the "Previous" & "Next" Hyperlink and as you progress through the pages they are as do the next 10 numbers of pages? Code:

[regex] Stripping Out "name" And "value" Values Out Of Tags, Aaargh
Searched through the site, but couldn't find the right regex syntax I was looking for.

the thing i want is, to extract with preg_match_all the given values in a tag...

ex.

$str = '<input type="text" name="name" value="value">'
$pattern = some magic stuff I need to know
preg_match_all($pattern, $str, $result);

And in result I want to have the values text, name and value AND it's important that the order doesn't matter
so structure of tags can be <input type =name= value=> or <input name= class= value= type=> etc, etc...

Group Mailing, Want To Suppress All The "to" Addresses In The "to:" Field
I want to do a mass emailing for a club.
I don't want all the clubs members to see all the addresses of the
other club members for privacy reasons.

How do I set up the php mail function to not display the recipients
email addresses, just to display something like, "U7 Soccer Club
Team"?

Php Reference In <SCRIPT> Tag Gives "Error On Page" In IE6.0
I have some problems with a PHP reference in a <SCRIPTtag, but only
with the Internet Explorer, which gives a "Error on page" message in
the Status Bar.
The code is as follows :
<script>

</script>

The error given is :

Line:24
Char:13
Error: Syntax error
Code: 0

Char 13 is the "<" or looking to the source of the page with the IE
browser, it's ";"

I get the error message as said before only in the Internet Explorer
browser and it does not affect the display nor the functionality of
the page, but it's not good looking ...

PHP Pages Getting 404 Error, "Page Cannot Be Displayed"...
I tried putting this into the PHP Installation forum but don't get any answers or suggestions there so I'm going to try it here and hope it doesn't get moved.

I'm on a Windows 2003/PHP 5.22 setup. I'm TRYING to upgrade from PHP 5.02 which did work on my server and quite well. I followed the upgrading and installation instructions layed out on the PHP.net set -- I still can't get it to work.

The install dumped all the PHP related files under "c:program filesphp". I've ensured that path is in my windows PATH statement for my env vars. I've also verified that "c:program filesphpphp-cgi.exe" is in my Web Service Extensions listing in IIS and the status is set to "Allowed".

From the command-line, I can execute my "test.php" file that has the phpinfo(); info function in it and it works fine. It's only when I try to use my web browser to access the php file that I get the 404 error, "page cannot be displayed". I know that IIS in general is working ok because I can point it to the default http://servername/iisstart.htm and it resolves to that page just fine. It's only when I change it to http://servername/test.php (which has my phpinfo()) function in it when I get the 404 error.

My web server just doesn't seem to be interpretting PHP files anymore and I can't figure out why.

Echo "";
I have a search script which returns a page of results, however I'd like the returned page to be in the same format as the rest of my site.
To do this I've tried adding the HTML for my site to my PHP page with echo" " commands. This works for the plain HTML, but my regular pages also use SSI to do other stuff (some of them even execute other PHP scripts to generate tables of data etc). I've tried

echo "";
but it doesn't work as I get a parse error. My question is, how do I go about doing this properly? Is this possible at all? And if not have you guys got any suggestions to get around this?

Any File Size Limit In <PARAM Name="***" Value="***"> ?
I embed an applet in my php script which has a parameter providing an
input file for the jar. Does this file has size limit?

The code is as follows:
<APPLET ARCHIVE="myapplet.jar" WIDTH=372 HEIGHT=360 VSPACE=0 HSPACE=0
ALIGN=middle>

<?php echo "<PARAM NAME="data" VALUE="myfile.">";?>

when "myfile" is beyond 15M, my applet cannot load sucessfully, but
while this file is limited like 5M or 7M, it works well.

Does anybody know is the reason caused by php script limit, applet
mechanism, or by different browser?

How To Do PHP "require()" Or TCL "source" In Bash Script
I can't figure out how to explain this any better than
this.

In PHP we have a command "require()" that obtains a file and logically
places it into another file.

I cannot figure out how to do this in bash script as the requirement
is necessary for a migration script to obtain the code from a .cfg
file and then be able for the "parent" script to run the code it
"imported" from the .cfg file, much like PHP's require() or TCL's
"source".

This is what I have so far and it fails:

if [ -f ivc.cfg ]; then
cat ivc.cfg
fi

Anyone really know bash script well please help, it's a barrier for me
not to be able to get just this one piece working.

No PHP Error. Just "Page Cannot Be Displayed"
I was wondering if someone could explain why I'm receiving this error. It's
like a 404 error but I think it might be something else.

Basically, I have a page where a user inputs his email address. The system
is supposed to look up the email address and send the associated password to
that email address. It worked up until a few months ago. Note that the
validation works. So, if the user tries to submit a blank text box, it
returns an error. If the email address is not found, it returns an error
"Email not found." But if the email is valid, it just dies. This code
worked a few months ago when I initially wrote it....

Coding "NEXT" And "PREVOIUS" Buttons
Hi

I am stuck here. I am doing a form which dispalys details of client companies. My query includes this statement:

.... WHERE CompanyName LIKE %$name% ....

What I need is following: if a query returns more then one result I what to "flip" through result with NEXT and PREVIOUS buttons.

Mysql/php - "LIMIT" And "ORDER"
In the following fragment of code, I am querying a database that in order to display a list of films. The list is very long and I would like to offer the possbility to restrain the range of results showned by page keeping in mind that the user should be able to browse forward or backward data if applicable. I know that I have to add the LIMIT method in the MySQL query but I have a hard time figuring how not to get lost in setting it dynamically in the PHP script.

Then I have a second question. Is there a more elegant / straightforward way to deal with the display order of the data (cf. $ot, $od and $oy)? Code:

Sticking "if" Or Changes Within A MySQL "where" Array?
I'm not exactly sure how to even ask the question, and I know my terminology
is not good as I'm a SQL beginner, but, here goes.

I need to find a way to make an if statement within an array...or, the
"while" portion of a recordset.

The best way I can ask is show what I mean.
http://oscarguy.mechphisto.net/awardbrowse.php
If you go there and select an award (like Best Picture), leave the year
field alone, and select YES and submit, you'll see a lot of results. And I
have HR's dividing each entry.

What I need to do is group all the entries of the same year, or at least
only put HR's between the blocks of years.
So, I'd have all the entries for 2002, an HR, then all for 2001, an HR, etc.

Here at the bottom I'll include my PHP code I'm using so far.
But I have no idea where to even start looking for an answer...if it's even
possible.
If someone can just give me the name of the function or process or
technique, then I can go Web/book searching myself...I just need a direction
of where to go.

Cookies And "include" Or "require"
i'm having a problem with my setcookie() instructions. Although there are absolutely
no html tags in front of them,for some reason PHP3 sends me back the message "oops...php3_SetCookie called after header has been sent"...

I do however use two "require" calls, one to a file with a .php extension, and one to a file with an .inc extension. At the beginning of each files there's a Could the cookie failure and the include functions be related ?

In my text, I have even wiped out any HTML tags such as "bold, paragraph, line break" tags, even in "echo" commands, but to no avail what am i doing wrong ?

"Array To String Conversion" Error When Constructing A Multi-dimensional Array
I'm a bit stumped as I am getting a "Notice: Array to String
Conversion" error when trying to do something that on the surface
should be a very simple task - create an array, and write a set of
values to them based on data submitted from POST Fields.

Code below:

$_SESSION["increment"] = array();
$x = 0 // Counter - This will be
incremented

$_SESSION["increment"][$x] = array("increment_bond" =>
$_POST["increment_bond"],
"increment_amount" = $_POST["increment_amount"],
"increment_comm_date1" = $_POST["increment_comm_date1"],
"increment_comm_date2" =$_POST["increment_comm_date2"],
"increment_comm_date3" = $_POST["increment_comm_date3"]);

It keeps throwing out that error, and does not write any of the POST
Values to the array (the POST values are definitely getting sent, so
that is not the problem).

If I dump out the value of $_SESSION["increment"], I get "1A" ?!?

I'm sure that there is a pretty simple mistake lurking somewhere - I
just can't seem to figure it out.

Checking If A Multi-dim. Array Has Been "filled Out"
I have the following recursive function which is supposed to check wether a multi-dimensional array has any "blank spaces" in it. PHP Code:

Checking "last Updated" On Remote Files.
How do I check the last updated time on remote files. I'd like my end result to be, a function that takes a list of urls, check the lastupdated date on that file (i.e., home page of someone's blog), so I can then grab the ten most recently updated among them, and print them, in descending order of update date.

Checking An Array And "splitting It Up"
I'm trying to create an image upload class and got into a little array problem. (File is attached to post. Sorry for the Icelandic) I pass the $_FILES['someuploadfiles'] to $this->uploadskrar and then in skoda() I cycle through the array and the if/else sentence is to filter out the bad apples, the images that don't f meet the standards set,

$this->ilagi_myndir is for pictures that meet the standards and $this->nilagi_myndir is for pictures that don't meet them. Those 2 arrays are are suppose to have the same structure as $this->uploadskrar and i'm not figuring out how.

Checking If $user & $pass = " "
if !( $user=="" || $pass=="");
mysql_query("INSERT INTO users (id, sn, pw)
VALUES ( '$idhigh + 1', '$user', '$pass')");

It wont load up my page when I try to run it with this in my page, what am I doing wrong? It checks my text boxes to see if the user and pass equals a blank input when the person clicks on the submit button, and if it does, then it does nothing.

Parse Errors With "case "action":
I want to call an action that is in a file called "configm.php" but I get a parse error on line 8. (the bit that goes 'case "add":') Code:

"Short Description" : String Character Limit
I am in the process of redesigning a web site for my work, we sell many products on eBay and are looking to sell multiple items on the site. I was thinking about doing a 3x3 display of random products on the front page, which I can code with no problems.

The "short description" shown on the front will be taken from the complete description of the product, but will need to be limited to a certain amount of characters (to keep each product display a reasonable size). The problem is that the ending character for the "short description" will not always be the end of the word. I need to figure out how to validate that it is the end of a word, even if it exceeds the character limit. I just don't want to end up with partial words.

Error Using Header("", FALSE) To Show Multiple Images From MySQL Db
Many people seems to have problems when displaying multiple images from their database (mySQL db). Often you can read error statements like "Header already sent out ...". To solve this, people often propose to use include files.

To keep the scipt it would be nice not having this problem, being able to sent out multiple headers to a browser without getting these error messages. In the PHP4 manual, we can read an option that can be added to the header statement, Header("xxx",FALSE). It would enable multiple headers to be sent out.

For instance the following statement:

while ($product = db_fetch_object($result)) {
header("Content-type: pv($product->filetype)",false);
echo pv($product->image)"
}

However, it doesn't work. Anybody has any idea why? Does anybody use this option FALSE with success?

Another "Fatal Error: Call To Undefined Function: Mysql_connect()"Question
I am getting the following error when I try to view a test page in my
browser. This test page just reads a table in mysql and outputs the
results.

Fatal error: Call to undefined function: mysql_connect() in
/var/web/public/test.php on line 2

I'm using:
Apache 2
MySQL 4.1.12
PHP 4.4.0

I have tried upgrading PHP to PHP5. I went back down to PHP4. I
verified that mysql.so was being loaded. I tried using the OLD_PASSWORD
feature in mysql. Verified that the PHP module is loaded in apache.

What is weird however (at least I think) is when I run the following via
telnet:

php ./test.php

It pulls up the page, connects successfully to the database and displays
the records. No error message.

Formmail.php Brings Up Error Message About Configuring "sendmail_from" Line
This may not be the best place to put this but i have set up apache as

server is set to be my university's smtp server (which i hope should
work). But it still comes up with the error.

Can't Install PHP - Keep Getting "Invalid Directory" Error Regarding The Path To Apache Httpd.h
I've installed Apache 1.3.36 on my Redhat EL 3 machine. Now I'm trying
to install PHP 5.1.4. I can not get the ./configure command to work. I
keep getting this error:

configure: error: Invalid Apache directory - unable to find httpd.h
under /usr/local/apache/include

So then I run this command:

find / -name httpd.h

which should find every file on my machine with the name "httpd.h".
These are the results I get:

/usr/local/apache/include/httpd.h
/home/shelley/apache_1.3.36/src/include/httpd.h

So I've rerun the ./configure command, using this first:

--with-apache=/usr/local/apche/include

and since that didn't work:

--with-apache=/home/shelley/apache_1.3.36/src/include/httpd.h

but I get the "Invalid directory" error with both addresses.

"Disk Quota Exceeded" Error When Trying To Use New Version Of PhpMyAdmin
I've a site where I've just installed a new version of phpMyAdmin
(version 2.8.1). I can't get it to work. I'm getting this error:

Warning: session_write_close(): write failed: Disk quota exceeded
Warning: session_write_close(): Failed to write session data (files).
Please verify that the current setting of session.save_path is correct
(/tmp)

I've also, on this same site, another copy of phpMyAdmin (version
2.2.7-pl1) installed. I installed it many years ago. It is working
without an error. So the problem is not with the site or the server or
the database, but with the newer version of phpMyAdmin. Perhaps I
configured it wrong? Does anyone here have experience debugging
phpMyAdmin installations,

Uploading Large Files - Error "stat Failed"
I have a page where i can upload binary file (using the HTML input
type=file approach). This works fine for relatively small files
(<6MB)) but when files get bigger (13MB) there is a problem.
The code of the php file is based upon the article in
http://www.onlamp.com/pub/a/php/200...php_mysql.html: uploading
large binary files using more than one table and more trhan 1 row per
file.

When I want to upload something of -say- 13MB the problems are:

1 takes ages to upload (slow connection? it's on my LAN),

2 after a while I get a error msg:
"Warning: stat failed for none (errno=2 - No such file or directory)
in /Users/marc/Sites/wwwweb/FTP/FileTransfer.php on line 91"

Lines 90 and 91 are below:
90clearstatcache();
91$time = filemtime($SrcPathFile);

(does this mean the tmp file is not there???)

I changed 4 variables in php.ini to accomodate the bigger file size:

max_execution_time=120
post_max_size=65M
upload_max_filesize=65M
memory_limit =65M

I changed the rights on the tmp file upload directory so that everyone
can write to it just to be sure...

Still I get the error.

Why am I not able to upload those big files?

Why does it take so long for the file to upload to the server? It
happens all on my LAN (no proxies enabled) so it should be faster....
even dloading a file from the internet is faster than this.

Force Reload Of Page When User Press "Back" Button
Is there a way to force a page to reload if a user har pressed the "Back" button in the browser.

"Warning: Page Has Expired" - How To Aviod When Using Browser Back Button?
In summary:
I want to a form to submit information via a HTTP POST, however, when using
Internet Explorer I want to be able to use the back button and all the
information retained. Presently we get a "Page has expired" message. How can
we avoid this?

Full details:
Having searched for postings on how to avoid the "Page has Expired" they are
numerous, however, I have not found one that answers the question
adequately.

Hence this posting.

One posting directed me to the following webpage:
http://in.php.net/session_cache_limiter

but I played around with "session_cache_limiter()" and it did not give the
desired results. (It seem to make no difference). Also many people say to
use HTTP GET instead but this is not an option in this case.

Where can I find concise definitive information on how to avoid "Warning:
Page has Expired" and allow the user to press the back button and see the
form as it was before they submitted it?

I have played around with the "a" and tried "w" and "a+", but the "w" will not contain the "Array" string but will over write the files contents.

Trouble With "string Format" In Fscanf
I think I am misunderstanding the manual's description of the fscanf() function. I do not seem to be able to produce the result I need. Here's my test code PHP Code:

Inserting The Contents Of A String Into An "if" Clause
I am writing a script which is intended to replace the often hijacked formmail.pl.
The form contains a hidden field (required) listing the required fields on the form.
I have written a loop which assembles a conditional string depending on what is in the "required" field

$string = "";
$j = "";
$fields = explode(",", $required);
foreach($fields as $data){$string.=$j." empty($$data) "; $j ="||"; }

this produces a nice string like "empty($email) || empty($Phone) etc..." I want to insert this into an if clause to determine whether to check these values are set. If I put if($string){.........}

of course it always evaluates as true. I have tried putting $string in quotes single and double, curly brackets, etc, but cannot get it working. I am sure this is simple but seem to have a blind spot.

Regular Expression - "" Chars At The End Of The String
I had a problem with string which have some chars at the end of the
string. For example:

$String = "I want this **** out of here\\";

I needed to remove it useing regular expression...i thinked that
something like "/+$/" is enough but i was wrong. I made some tries
and finaly i removed "" chars it with "/+$/". It works (i'm proud
with myself :)), but i can't understand why matchs single , and
not...

Please Explain Or Refer: $string = Isset($xyz) ? $xyz : "something Else";
"$string = isset($xyz) ? $xyz : "something else";"

inference) what it does, but have not found any documentation on this
type of syntax.

Any one have links to this shortuct(?) syntax and other types of
syntax?

"Page Not Found" Because Script Takes Too Long?
I am developing an online calculator for my school district. Without going into too much education-ease, the idea is simply that the user puts in some numbers, and the system crunches those numbers. The form, and the form handler are contained in one script, using a hidden variable to tell the script to process the information upon submitting to itself...

Everything was working great, until I put in the various algorithms... They are not particularly numerous, lengthy, or complicated, but clicking on 'Submit' now yields a 'Page not found' error. When I commented out half of the math, the page loaded ok...so it seems to be 'timing out'... I'm baffled.... this script is simple, and short... what could be the problem????

Here is the math part of the script..
