i'm trying to save text in a form to a session, and use the session to convert it to a .png file :) but it doesnt seem to work, and i dont know where its messing up.

this is the form page:

<html>
<form method="POST" action="http://akwardsaw.hostoi.com/createpic.php">
    <input type="text" name="text" value="text"> 
    <input type="submit" value="Change"> 
</form>
</html>

and the link: here

here is the file to convert that text to a .png file:

<?php
$_SESSION['text']=$_POST['text']; 
session_start();


header("Content-type: image/png");

function create($text){

$im = imagecreate(100, 30);

$bg = imagecolorallocate($im, 255, 255, 255);
$textcolor = imagecolorallocate($im, 0, 0, 255);

imagestring($im, 5, 0, 0, $text, $textcolor);

imagepng($im);
imagedestroy($im);
}

if(isset($_SESSION['text']))
create($_SESSION['text']);
else {
$_SESSION['text']="wat";
create($_SESSION['text']);
}
?>

here

making the pic works, but it doesnt save the POST text from the form into a session :(

This seems to work for me..

<?php
session_start();
header("Content-type: image/png");

function create($text){

$im = imagecreate(100, 30);

$bg = imagecolorallocate($im, 255, 255, 255);
$textcolor = imagecolorallocate($im, 0, 0, 255);

imagestring($im, 5, 0, 0, $text, $textcolor);

imagepng($im);
imagedestroy($im);
}

if(isset($_SESSION['text']))
create($_SESSION['text']);
else { 
$_SESSION['text']="wat";
create($_SESSION['text']);
}
?>

I also don't think you can post a form to the session array, it's either POST or GET.

so, to set it, it would be:

$_SESSION['text']=$_POST['text'];?

sorry for double post, but how would you set the text in the form as a session? thats my next problem =\ i'v tried

$_SESSION['text']=$_POST['text'];

in the form, but meh

You can do that after you've committed the form with POST. So in your PHP script you add that line and in the form you have method="POST".

sorry for a semi-grave dig, but when i tried to fix it, it still doesnt save to the session =\

what other ways can i make this work?
