POST problem

[khjart]

Hi,

I have a problem with a form and the POST method. Consider this example:

<form action="/dir-to-this-form" method="POST">
	<input type="text" name="var">
	<input type="submit" value="send">
</form>

<?
echo $_POST['var'];
?>

It is supposed to output the content of var, but it doesn't. It simply won't get the variable. But when I use GET or set action="/dir/script.php" it works. Does anybody know a way to fix this example, that would work with POST?

There's no checking there. Are you submitting it first? Try this:

<?php
if(isset($_POST['var'])) {
   echo $_POST['var'];
}
else {
?>
<b>Var Not Present</b>
<br />
<form action="<?php echo $_SERVER['PHP_SELF']?>" method="POST">
    <input type="text" name="var">
    <input type="submit" value="send">
</form> 
<?php
}
?>

Ah, it was just a simple mistake in the form.
I just had to set a traling slash i action; like this
action="/dir-to-this-form/"

Thanks for your help, though.
