[Resolved] Strange problem with POST

[gottgens]

Hi all,

I was wondering if somebody could help me with the following problem:

I created a form, like this:

<form name="form1" action="threadform.php" method="post">
<input type="text" name="MyName">
<input type= "submit" name="Submit" value="Send info!"
</form>

The php section of the"threadform.php" file looks like this:

<?php
print "Your name is $MyName";

?>

You would assume that when I fill in my name, Roderick, the php file would return "Your name is Roderick". BUt somehow It won't work. I've tried several options, like printf and echo for printing. I even tried the method "GET". It still doesn't work. I have no clue what it could be.

I'm running PHP 4.3.3RC1 on Apache 2.0.46 server. Could it be a bug in the PHP module? Am I doing something really stupid? Who knows? I cann't find any information about a possible bug or something in the release notes. Maybe I should downgrade my Apache / php version?

I hope some-one can help me.

Thanks in advance.

Kind regards,

Roderick Gottgens

<input type="text" name="MyName">
<input type= "submit" name="Submit" value="Send"
</form>
<?
if($Submit==Send)
{
$MyName=$_POST['MyName'];

if(empty($MyName))
{
exit;
}

echo "Your name is $MyName";

}
?>

It's not a bug ... register globals is turned off ... you just need to get the variables manually (as shown above) instead of counting on PHP to unpack them all for you.

Hi Acey,

Thanks for your quick response. It has been a while since I developed with PHP (actually, I started developing with PHP again just a few days ago).
Will the script I've used never work? In the past I've always scripted like my example. Is there no way to do it like that again? Somewhere on this forum I've read a post about a php.ini variable (something like setting the variable "register_globals" to "on"). If I would do this, will that make me use my old scripts again? Or do I have to rewrite them with your solution?

Thanks in advanced.

Kind regards,

Roderick Gottgens

Thanks SteadyGuy !!!

You're welcome ... just so you know, It is highly inadvisable to turn register globals on, as it is extremely insecure ...

It isnt really "extremely insecure", if you code with preventing variable poisoning in mind.

Rather, it reduces the chance of variable poisoning, and it is easier, generally, to use the superglobals.

I know this is pretty well closed, but I thought I would throw this line up real quick, something else that would work...

if (isset($POST['MyName'])) { $MyName=$POST['MyName']; }else{ exit; }

Good Day...

Just as an example of how NOT to program, right?

LOL, likely huh! I'll mark this resolved now.
