+<h1>Smiley Helper</h1>
+
+<p>The Smiley Helper file contains functions that let you manage smileys (emoticons).</p>
+
+
+<h2>Loading this Helper</h2>
+
+<p>This helper is loaded using the following code:</p>
+<code>$this->load->helper('smiley');</code>
+
+<h2>Overview</h2>
+
+<p>The Smiley helper has a renderer that takes plain text simileys, like <dfn>:-)</dfn> and turns
+them into a image representation, like <img src="../images/smile.gif" width="19" height="19" border="0" alt="smile!" /></p>
+
+<p>It also lets you display a set of smiley images that when clicked will be inserted into a form field.
+For example, if you have a blog that allows user commenting you can show the smileys next to the comment form.
+Your users can click a desired smiley and with the help of some JavaScript it will be placed into the form field.</p>
+
+
+
+<h2>Clickable Smileys Tutorial</h2>
+
+<p>Here is an example demonstrating how you might create a set of clickale smileys next to a form field. This example
+requires that you first download and install the smiley images, then create a controller and the View as described.</p>
+
+<p class="important"><strong>Important:</strong> Before you begin, please <a href="http://www.codeigniter.com/downloads/smileys.zip">download the smiley images</a> and put them in
+a publicly accessible place on your server. This helper also assumes you have the smiley replacement array located at
+<dfn>application/config/smileys.php</dfn></p>
+
+
+<h3>The Controller</h3>
+
+<p>In your <dfn>application/controllers/</dfn> folder, create a file called <kbd>smileys.php</kbd> and place the code below in it.</p>
+
+<p><strong>Important:</strong> Change the URL in the <dfn>get_clickable_smileys()</dfn> function below so that it points to
+your <dfn>smiley</dfn> folder.</p>
+
+<p>You'll notice that in addition to the smiley helper we are using the <a href="../libraries/table.html">Table Class</a>.</p>
+
+<textarea class="textarea" style="width:100%" cols="50" rows="25">
+<?php
+
+class Smileys extends Controller {
+
+ function Smileys()
+ {
+ parent::Controller();
+ }
+
+ function index()
+ {
+ $this->load->helper('smiley');
+ $this->load->library('table');
+
+ $image_array = get_clickable_smileys('http://www.your-site.com/images/smileys/');
+
+ $col_array = $this->table->make_columns($image_array, 8);
+
+ $data['smiley_table'] = $this->table->generate($col_array);
+
+ $this->load->view('smiley_view', $data);
+ }
+
+}
+</textarea>
+
+<p>In your <dfn>application/views/</dfn> folder, create a file called <kbd>smiley_view.php</kbd> and place this code in it:</p>
+
+
+<textarea class="textarea" style="width:100%" cols="50" rows="20">
+<html>
+<head>
+<title>Smileys</title>
+
+<?php echo js_insert_smiley('blog', 'comments'); ?>
+
+</head>
+<body>
+
+<form name="blog">
+<textarea name="comments" cols="40" rows="4"></textarea>
+</form>
+
+<p>Click to insert a smiley!</p>a
+
+<?php echo $smiley_table; ?>
+
+</body>
+</html>
+</textarea>
+
+
+<p>When you have created the above controller and view, load it by visiting <dfn>http://www.your=site.com/index.php/smileys/</dfn></p>
+
