PHP not parsing forms

wisptech

Here is the code that I used to test my server, very simple, right?
But when I click on submit, nothing.. I've also tried similar things
with php and mysql and all it did was create empty fields in the table.
What am I doing wrong? Please help, Ultimatly I want to parse a form
into a mysql database, but if I can't get the php engine to pass data
from the forms correctly then it's no use to go any further.

<?php

if ($submit == "click"){
echo "Hello, $UserName";
}
else{
echo '
<html><body>

<form method="post" action="form.php">

Enter Your Name
<input type="text" name="UserName"></input><br>

<input type="submit" name="submit" value="click"></input>

</form>

</body></html>
';
}

?>

Your code doesn't work because register globals have been disabled. This is
easily fixed by retrieving the post data explicitly.

Add this to the top of your PHP code:

$submit = $_POST['submit'];

More info here: <http://uk.php.net/register_globals>

<?php

?>
</body></html>

Since 4.2.0 register_globals [1] is off by default due to security
reasons [2]. One should use super globals (introduced in 4.1.0) instead
to get to user supplied data [3]. So either fix:

-fix your code [4]:
if(isset($_POST['submit']) && $_POST['submit']=="click")
{
echo 'Hello, '.$_POST['UserName'];
}
-quick&dirty hack:
extract($_REQUEST);
in the global scope.
-enable register_globals

1: http://www.php.net/manual/en/ini.cor...gister-globals
2: http://www.php.net/manual/en/security.globals.php
3: http://www.php.net/manual/en/languag...s.superglobals
4: $_POST['UserName'] should offcourse be escaped properly (with
htmlspecialchars in this particular case).

You probably have register_globals turned off (and you should).
Put this in the beginning of your script:

$UserName = $_POST['UserName'];
$click = $_POST['click'];
