<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 clickable 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>
<?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>
