Create a helper called SmileyHelper, add it to the GuestBookController
with var $helpers = array('Bbcode', 'Smiley');
In your view where you output the post, you should be using something
along the lines of $bbcode->display($this->data['GuestBook']
['post']); Make this in $smiley->display($bbcode->display($this-
>data['GuestBook']['post']));
Then the smiley helper display() function should be a series of
regular expressions that convert :) to <img src="" />.
To use your Smiley model in your helper you need something along the
lines of:
<?php
loadModel('smiley');
class SmileyHelper extends Object {
function display($in){
$smiley = new Smiley();
$smilies = $smiley->findAll();
// loop over the smilies and preg_replace all the smilies in
$in
}
}
?>
