Introduction

Provides a Formfield for saving a string of tags into either a many_many relationship or a text property. By default, tags are separated by whitespace. Check out a [http://remysharp.com/wp-content/uploads/2007/12/tagging.php](demo of the javascript interface).

Features

• Bundled with jQuery-based autocomplete library (http://remysharp.com/2007/12/28/jquery-tag-suggestion/) which is applied to a textfield
• Autosuggest functionality (currently JSON only)
• Saving in many_many relation, or in textfield
• Static list of tags without hitting the server
• Tab-autocompletion of tags
• Customizeable tag layout through css
• Unobtrusive - still saves with Javascript disabled
• Full unit test coverage

Usage

Tags as Objects

Article Model

class Article extends DataObject {
	static $many_many = array(
		'RelationTags' => 'Tag'
	);
}

Tag Model

class Tag extends DataObject {
	static $db = array(
		'Title' => 'Varchar(200)',
	);

	static $belongs_many_many = array(
		'Articles' => 'Article'
	);
}

Formfield Instanciation:

$tagField = new TagField('RelationTags', null, null, 'Article')

Tags as Textfields

Article Model

class Article extends DataObject {
	static $db = array(
		'TextTags' => 'Text'
	);
}

Formfield Instanciation:

$tagField = new TagField('TextTags', null, null, 'Article')

Static Tags without Autosuggestion

$tagField = new TagField('TextTags', null, null, 'Article');
$tagField->setCustomTags(array('mytag','myothertag'));
