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://codeigniter.com/download_files/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 CI_Controller { - - function __construct() - { - parent::__construct(); - } - - function index() - { - $this->load->helper('smiley'); - $this->load->library('table'); - - $image_array = get_clickable_smileys('http://example.com/images/smileys/', 'comments'); - - $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 smiley_js(); ?> - -</head> -<body> - -<form name="blog"> -<textarea name="comments" id="comments" cols="40" rows="4"></textarea> -</form> - -<p>Click to insert a smiley!</p> - -<?php echo $smiley_table; ?> - -</body> -</html> -</textarea> - - -<p>When you have created the above controller and view, load it by visiting <dfn>http://www.example.com/index.php/smileys/</dfn></p> - - -<h3>Field Aliases</h3> - -<p>When making changes to a view it can be inconvenient to have the field id in the controller. To work around this, -you can give your smiley links a generic name that will be tied to a specific id in your view.</p> -<code>$image_array = get_smiley_links("http://example.com/images/smileys/", "comment_textarea_alias");</code> - -<p>To map the alias to the field id, pass them both into the smiley_js function:</p> -<code>$image_array = smiley_js("comment_textarea_alias", "comments");</code> - - -<h1>Function Reference</h1> - -<h2>get_clickable_smileys()</h2> - -<p>Returns an array containing your smiley images wrapped in a clickable link. You must supply the URL to your smiley folder -and a field id or field alias.</p> - -<code>$image_array = get_smiley_links("http://example.com/images/smileys/", "comment");</code> -<p class="important">Note: Usage of this function without the second parameter, in combination with js_insert_smiley has been deprecated.</p> - - -<h2>smiley_js()</h2> - -<p>Generates the JavaScript that allows the images to be clicked and inserted into a form field. -If you supplied an alias instead of an id when generating your smiley links, you need to pass the -alias and corresponding form id into the function. -This function is designed to be placed into the <head> area of your web page.</p> - -<code><?php echo smiley_js(); ?></code> -<p class="important">Note: This function replaces js_insert_smiley, which has been deprecated.</p> - - -<h2>parse_smileys()</h2> - -<p>Takes a string of text as input and replaces any contained plain text smileys into the image -equivalent. The first parameter must contain your string, the second must contain the URL to your smiley folder:</p> - -<code> -$str = 'Here are some simileys: :-) ;-)'; - -$str = parse_smileys($str, "http://example.com/images/smileys/"); - -echo $str; -</code> -</div> -<!-- END CONTENT --> - - -<div id="footer"> -<p> -Previous Topic: <a href="security_helper.html">Security Helper</a> - · -<a href="#top">Top of Page</a> · -<a href="../index.html">User Guide Home</a> · -Next Topic: <a href="string_helper.html">String Helper</a> -</p> -<p><a href="http://codeigniter.com">CodeIgniter</a> · Copyright © 2006 - 2011 · <a href="http://ellislab.com/">EllisLab, Inc.</a></p> -</div> - -</body> -</html>
