php text box variables

[furmonk]

I dont understand why this happens, I followed multiple tutorials and still
this error happens

<?php
if(isset($_GET['ex']))
{
		$ex = $_GET['ex'];
}		
?>

<form action="" method="POST">
text: <input type="text" name="ex">
<input type="submit" name="submit" value="submit">
</form>
<?php
echo $ex
?>

How do I get the variable to work

<?php>
if(isset($_GET['ex']))
{
$ex = $_GET['ex'];
}
?>

<form action="" method="POST">
text: <input type="text" name="ex">
<input type="submit" name="submit" value="submit">
</form>
<?php
echo $ex
?>

echo $ex

Thats your problem that code isnt finished. Either finish it or remove it.

Yeah i tested it the $ex is a unnecessary code and it messes up the whole script. Just take it off thats how i fixed it.

Awhhhh i see why its not working

<?php
if(isset($_GET['ex']))
{
$ex = $_GET['ex'];
}
?>

<form action="" method="POST">
text: <input type="text" name="ex">
<input type="submit" name="submit" value="submit">
</form>

<?php
echo $ex
?>

You need to fix that spot to this

echo $ex
<?php>

and at the top you made it <?php

Gotta make it <?php> you just made simple mistakes you didnt notice.
