Yii2 Taxonomy

Yii2 Taxonomy management. A component which adds generic taxonomy functionalities to your application. The component comes with a couple of term definitions(tags, properties). These additional info is added via addition tables created by the extension. The extension also offers a search behavior which can be attached to AR instances for easier searching.

Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist nkostadinov/yii2-taxonomy "*"

or add

"nkostadinov/yii2-taxonomy": "*"

to the require section of your composer.json file.

Then you need to configure the taxonomy component to your configuration file.

    'components' => [
        .......
        'taxonomy' => [
            'class' => 'nkostadinov\taxonomy\Taxonomy',
        ],
        .......

Finally you need to run the initial migration

yii migrate --migrationPath=@nkostadinov/taxonomy/migrations

Usage

If you need to use the management interface for taxonomies you must add the Taxonomy module to you configuration

    'modules' => [
        ......
        'taxonomy' => [
            'class' => 'nkostadinov\taxonomy\Module'
        ],

It is recommended to use the taxonomy MODULE only on dev environment to create the taxonomies just like gii. When you add a taxonomy via the interface the component creates a migration so you can execute it on production later.

Sample usage (tags): //return a taxonomy object used to manipulate this taxonomy(taxonomy must be defined before that and the migrations executed)

 $taxonomy = Yii::$app->taxonomy->getTerm('post_tags');

//Adding terms (e.g. tags) to an object with id $post_id

 $taxonomy->addTerm($post_id, ['read', 'important', 'new']);

//Deleting tags

 $taxonomy->removeTerm($post_id, ['important', 'new']);

//Retrieving tags

 $taxonomy->getTerms($this->id);

// returns ['read']

Taxonomies

The bundled taxonomies with these package are :

TagTerm

Basically tag represent taxonomies which are added to an object. They do not have a value. You can add multiple tags to an item.

PropertyTerm

They are the same as tag terms but they DO have a value. You can add multiple properties to an item.

CategoryTerm

Ability to create hierarchical terms (e.g. categories)
