Smiley engine

[kid_drew]

Anyone know where I can find a free smiley engine to use on a website?  I could write one, but I bet there's already one out there.

I am not realy sure what you mean by smiley engine? Please explain what it is and what it does

[kid_drew]

Sorry, I guess that wasn't clear.  I want a class that I can plug into an existing website that will parse text and pick out the tags between colons and replace with smilies.  I.e., if it finds :grin: or something similar, it will replace with  ;D just like this board does.  I'd like to just have a list of tags and replacement images stored in my db.

Or if anyone has a good tutorial for how to create a smilie engine quickly, I'd take that too.

Try something like this (I haven't tested it):

[code]<?php
$smileys = array(
'smile' => ':)',
'smiley2' => ':D',
);

foreach($smileys as $image => $code)
{
$images[] = "<img src='smileys/{$image}.gif' alt='{$code}' />";
}

$text = str_replace($smileys,$images,$text);
?>[/code]

Just use:

str_replace( ":grin:", "<img src='grin.png' />", $message_content )

That will replace :grin: with an image (a smilie) everytime it finds it in the $message_content. You could use an array or something to store the smilie information and go through a for loop to replace them with image smilies.

^LOL you all beat me to it... I realy need to learn to type faster..lol

Yea that would be a bbcode.

Here is a simple one

[code=php:0]
function addSmiles($text) {
     $pattern = array('=)', ':grin', ':somethingelse');
     $replacements = array('<img src="path/to/yourimage">', '<img src="yourimage">', '<img src="image">');
     $bbcode = str_replace($pattern, $replacements, $text);
     return $bbcode;
}

$text = $_POST['text'];
$newText = addSmiles($text);
echo $newText;
[/code]

Like I said this is simple. I wrote this one the fly so let me know if there are any errors that come up.

hope that helps,
Tom

If you google code phpBB or phpNuke you'll find that they use a pretty nifty regex pattern replace to handly their smileys.
