Yii2 Moderation Extension
A simple Content Moderation System for Yii2 that allows you to Approve or Reject resources like posts, comments, etc., (*2)
, (*3)
Installation
The preferred way to install this extension is through composer., (*4)
Either run, (*5)
php composer.phar require --prefer-dist yii2mod/yii2-moderation "*"
or add, (*6)
"yii2mod/yii2-moderation": "*"
to the require section of your composer.json., (*7)
Configuration
To enable moderation for a model, use the yii2mod\moderation\ModerationBehavior behavior and add the status and moderated_by columns to your model's table., (*8)
Create a migration to add the new columns. Example Migration:, (*9)
<?php
use yii\db\Migration;
/**
* Handles adding moderation columns to table `post`.
*/
class m161117_092603_add_moderation_columns_to_post_table extends Migration
{
/**
* @inheritdoc
*/
public function up()
{
$this->addColumn('post', 'status', $this->smallInteger());
$this->addColumn('post', 'moderated_by', $this->integer());
}
/**
* @inheritdoc
*/
public function down()
{
$this->dropColumn('post', 'status');
$this->dropColumn('post', 'moderated_by');
}
}
To use ModerationBehavior, insert the following code to your ActiveRecord class:, (*10)
use yii2mod\moderation\ModerationBehavior;
class Post extends ActiveRecord
{
/**
* @inheritdoc
*/
public function behaviors()
{
return [
ModerationBehavior::class,
];
}
}
By default, ModerationBehavior will automatically set the moderated_by attribute., (*11)
If your attribute names are different, you may configure the [[statusAttribute]] and [[moderatedByAttribute]]
properties like the following:, (*12)
use yii2mod\moderation\ModerationBehavior;
class Post extends ActiveRecord
{
/**
* @inheritdoc
*/
public function behaviors()
{
return [
[
'class' => ModerationBehavior::class,
'statusAttribute' => 'status_id',
'moderatedByAttribute' => 'moderator_id', // or set to `false` to disable this attribute.
],
];
}
}
Usage
In next examples I will use Post model to demonstrate how the behavior and query class works. You can moderate any ActiveRecord Model., (*13)
Moderate Models
ModerationBehavior provides the following methods for model moderation:, (*14)
$post->markApproved(); // Change post status to Approved
$post->markRejected(); // Change post status to Rejected
$post->markPostponed(); // Change post status to Postponed
$post->markPending(); // Change post status to Pending
Model Status
ModerationBehavior also provides the following methods for checking the moderation status:, (*15)
$post->isPending(); // Check if a post is pending
$post->isApproved(); // Check if a post is approved
$post->isRejected(); // Check if a post is rejected
$post->isPostponed(); // Check if a post is postponed
Events
By default [[yii2mod\moderation\ModerationBehavior]] triggers [[yii2mod\moderation\ModerationBehavior::EVENT_BEFORE_MODERATION]], (*16)
You may attach the event handlers for this event to your ActiveRecord object:, (*17)
$post = Post::findOne($id);
$post->on(ModerationBehavior::EVENT_BEFORE_MODERATION, function ($event) {
$event->isValid = false; // prevent moderation for the model
});
You may also handle these events inside your ActiveRecord class by declaring the corresponding method:, (*18)
use yii2mod\moderation\ModerationBehavior;
class Post extends ActiveRecord
{
/**
* @inheritdoc
*/
public function behaviors()
{
return [
ModerationBehavior::class,
];
}
public function beforeModeration()
{
$this->moderated_at = time(); // log the moderation date
return true;
}
}
Query Models
ModerationQuery adds the ability of getting only approved, rejected, postponed or pending models. Usage example:, (*19)
use yii2mod\moderation\ModerationQuery;
class Post extends ActiveRecord
{
public static function find()
{
return new ModerationQuery(get_called_class());
}
}
Now you can use the following methods:, (*20)
Post::find()->approved()->all(); // It will return all Approved Posts
Post::find()->pending()->all(); // It will return all Pending Posts
Post::find()->rejected()->all(); // It will return all Rejected Posts
Post::find()->postponed()->all(); // It will return all Postponed Posts
Post::find()->approvedWithPending()->all() // It will return all Approved and Pending Posts
