a prob with php and form's

[abraxas@debian]

ok, my prob:

on my pc, i've got an apache server (1.3.26) with dynamic php support (php 4.2.3). to explain my problem just look an the following code:

<form name="formular1" action="formular1.php" method="get">
Quadrieren:<input type=text name=zahl></input><br><br>
<input type=submit name=rechnen value=ausrechnen></input>
</form>

<?php
if($rechnen){
$quadrat=$zahl*$zahl;
echo "Das Quadrat ist <b><font color=#0020FF>$quadrat</font></b>";
}
?>

yes, it's in german *gg*. the problem is that php can't access the variable "rechnen" from the form.
the script sould work at all. "rechnen" has "ausrechnen" as a string-value so i don't know why php can't use it. other php-scripts with no form content works well.

that's very bad and i'm glad about every idea ;-)).
I think it has somethink to do with the php.ini (the php-options file)

ok, i count on you *gg*, abraxas

change method="get" to method="post"

sorry, but it isn't so easy *gg*.
but be sure, i've tried the get-post change *gg*. the same, php can't access the form.

the same script works with an apache installation with php cgi-implementation under windows *gg*.

but php-developing under windows with apache?? sounds strange ;-)))

but thx for your reply, any more ideas???

Have you tried echoing the value of $rechnen? It seems to me that you should get it handily - I've used the same technique on Windows and FreeBSD using PHP, with a default php.ini.

I'm experiencing the same issue. I have apache 2 with php 4.2.3 and when I have a form that has a submit button, the variables are not being access from the php script. I have looked at the php.ini but could not see anything relating to forms. Any ideas?

I think I found an answer for you. If you have global_registers off in php.ini, you will not be able to use the variable name. Instead you have to use $_POST["itemname"] to get the value of the form item. Here is a tutorial on forms that explains this: http://www.php.net/manual/en/tutorial.forms.php.

BIG THX FOR YOUR HELP!!!

Yes, the "register_globals" was the needed option. When it's set to "On" all works fine.

There is something written about security problems with this option. Does anyone know what this could meens?
