Smiley Helper

- -

The Smiley Helper file contains functions that let you manage smileys (emoticons).

- - -

Loading this Helper

- -

This helper is loaded using the following code:

-$this->load->helper('smiley'); - -

Overview

- -

The Smiley helper has a renderer that takes plain text simileys, like :-) and turns -them into a image representation, like smile!

- -

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.

- - - -

Clickable Smileys Tutorial

- -

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.

- -

Important: Before you begin, please download the smiley images and put them in -a publicly accessible place on your server. This helper also assumes you have the smiley replacement array located at -application/config/smileys.php

- - -

The Controller

- -

In your application/controllers/ folder, create a file called smileys.php and place the code below in it.

- -

Important: Change the URL in the get_clickable_smileys() function below so that it points to -your smiley folder.

- -

You'll notice that in addition to the smiley helper we are using the Table Class.

- - - -

In your application/views/ folder, create a file called smiley_view.php and place this code in it:

- - - - - -

When you have created the above controller and view, load it by visiting http://www.your=site.com/index.php/smileys/

- -
