|

|
|
<p>The Smiley helper has a renderer that takes plain text smileys, like
|
|||
|
|
:-) and turns them into a image representation, like <img alt="smile!" src="../_images/smile.gif" /></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>

<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>

|

This helper also assumes you have the smiley replacement array
