Dynamic image Help

thematking

Hey, i was just wondering if anyone could help me with this dynamic image creator. Everything seems to be working fine, except when the text is inputted, it does not show up. Here is the website...http://thematking.com/residential/doormats/vinyl-link/test2.php and here are the codes

The code for the image

<?php
$txt = htmlspecialchars(stripslashes($_GET['txt']));

$image = imagecreatefrompng("images/backgroundsmall.png");
$color = imagecolorallocate($image, 100, 100, 100);

imagestring ($image, 3, 10, 9, $txt, $color);


imagepng($image);
imagedestroy($image);  

?>

and the code for the page

<?php require ($_SERVER['DOCUMENT_ROOT'] . "/includes/functions.inc.php"); ?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
    <meta http-equiv="content-type" content="text/html; charset=iso-8859-1">
    <title>images</title>
</head>
<body>
<form name="imagetext" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="GET">
<label for="text">Enter your text: </label><input type="text" value="" name="txt" size="10" maxlength="20">
<input type="submit">
</form>
<?php 
if(isset($_POST['submit'])) {

$txt = htmlspecialchars(stripslashes($_GET['txt']));

  echo "<img src='test.php?txt=$txt' alt='echo image'>";

} else {
  echo "<img src='test.php' alt='elseif image'>";
}
?>
</body>
</html>

any help would be appreciated..thanks.

edit - looking at it with the code, it looks like theres something wrong with the form part on the page, how can i write that cleaner?

Three things.

First, you have a form method of GET but you are testing for $_POST['submit']

Second, since IE8 won't pass the submit in a POST, I'd check for $_GET['txt']

Third, redo your label like this:

<label for="txt">Enter your text: </label>

wow, thanks a lot..works like a charm

a few more questions if you are able to answer them
1. how can i change it to use a custom made font at size 78 that i made that only allows you to type letters
2. how can i allow them to pick the colors for both the text and the background..the background wil have to be somewhat transparent im guessing
and last one
3. how can i make it so the text is centered no matter how many letters you write, (as long as it is under the maximum)

thanks again mr. baseball, if you cannot help, i appreciate everything you have done so far

Well, I'd read up on the image functions in the PHP manual to learn all those things:
