The plugin allows you to attach it to a model with a HABTM relationship established to a tagging based relationship, erm a Posts model to Tags. It will also give you a nice interface for the end user to add tags with, for example:

Setting up the plugin is quite simple:

cd app/plugins/
git clone git@github.com:voidet/tag_time.git

From there you now need to attach the Tag Time behaviour to the model you wish to associate tags with, for example app/models/Post.php

<?php

class Post extends AppModel {

public $actsAs = array('TagTime.TagTime');
public $name = 'Post';
public $hasAndBelongsToMany = array('Tag');

}

?>

Of course you will need to create two tables, your join table (posts_tags) and your tags table (tags):

CREATE TABLE `posts_tags` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`post_id` int(11) unsigned NOT NULL,
`tag_id` int(11) unsigned NOT NULL,
PRIMARY KEY (`id`)
)

CREATE TABLE `tags` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`tag` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
)

Next up adding the JS and CSS into your layout, which may change at a later date:

<?php echo $this->Html->css('/tag_time/css/jquery.tagsinput');
echo $this->Javascript->link('/tag_time/js/jquery.tagsinput');

Now in your view for your add/edit pages you will need to create your tags field like:

echo $this->Form->input('Tag.tags', array('div' => array('class' => 'tags-input input'), 'label' => 'Tags'));

What is going on the with div class you ask? Well this is how I have linked the taggable jQuery plugin to the input field, which will then act like a tags field. So for the last step, you need to add in some js into the view or into your js file:

<script type="text/javascript">
$(function(){
$('.tags-input input').tagsInput();
});

I hope to simplify this a bit more, just decided to make a blog post after an hour of making the plugin. If you have any improvements please let me know. Stay tuned to the github page for future updates.
