I'm not a beginner as such to the language of PHP, however the GD function is puzzling me... I would appreciate a script (with comments if possible) which merged with a HTML based form, would allow me to generate a text based image.
All attempts, working or otherwise, will be appreciated and reputation will be awarded to such users.
Thank you, James.
You can change GET to POST, and on your basic form have a field named "m", where the user enters their message. Alternatively, you could use JavaScript to make your page display the image more dynamically:PHP Code:<?php
header('content-type: image/png');
$m = ($_GET['m']) ? $_GET['m'] : 'No Message';
$image = imagecreate(250, 25);
$black = imagecolorallocate($image, 255, 255, 255);
$white = imagecolorallocate($image, 0, 0, 0);
imagestring($image, 1, 10, 10, $m, $white);
imagepng($image);
imagedestroy($image);
?>
HTML Code:<html>
<head>
<title>GD Example</title>
<script type="text/javascript">
<!--
function li() {
var m = document.getElementById('message');
var i = document.getElementById('image');
i.src = 'image.php?m='+m.value;
m.value = '';
m.select();
}
-->
</script>
</head>
<body>
<pre>
<input id="message" /> <button onclick="li();">Display</button>
<img src="image.php" id="image" />
</pre>
</body>
</html>
