What's it all about?

With this behavior, you can generate an URI for a single or combination of columns in your table. Some call it permalink, others call it slug or human readable url.

Imagine a blog table

| id | category | title                             |
|----+----------+-----------------------------------|
|  1 | security | NASA Server hacked by hacker kids |
| ...

So you'd like a better URL than that?

How to get it done

• Add another column called "slug" to your table
• Download this extension and drop it into your protected/extensions folder,
• Add the behavior to your model (shown below)

If you're using git, I'd recommend:

cd <YOUR YII-PROJECT>
mkdir -p protected/extensions/behaviors (optional)
git submodule add git://github.com/mintao/yii-behavior-sluggable.git protected/extensions/behaviors/SluggableBehavior

Demo configuration of this behavior for your model

/**
 * Behaviors for this model
 */
public function behaviors(){
  return array(
    'sluggable' => array(
      'class'=>'ext.behaviors.SluggableBehavior.SluggableBehavior',
      'columns' => array('category', 'title', 'author.name'),
      'unique' => true,
      'update' => true,
    ),
  );
}

• class Defines the path where to find the SluggableBehavor.php
• columns Needs to be an array of the fields to use for slug creation
• unique Set this to true to ensure a unique slug (Numbers will be added to duplicate slugs, if already existing)
• update Set this to true is every time you change the entry, the slug should be updated too. Set it to false, if the slug should be only created once
