Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist yii2mod/yii2-comments "*"

or add

"yii2mod/yii2-comments": "*"

to the require section of your composer.json.

Configuration

Database Migrations

Before using Comments Widget, we'll also need to prepare the database.

php
php yii migrate [email protected]/yii2mod/yii2-comments/migrations

Module setup

To access the module, you need to add the following code to your application configuration:

php
'modules' => [
    'comment' => [
        'class' => 'yii2mod\comments\Module',
    ],
]

NOTE: Module id must be

comment
and not otherwise. This is because it is referred somewhere in the code with such name. A PR to fix it to use configured module id is welcome.

Now you can access to management section through the following URL: http://localhost/path/to/index.php?r=comments/index

By default only users with

admin
role have access to comments management section. But, you can override
accessControlConfig
property for ManageController.

Notes:

1) Delete button visible only for users with

admin
role.

2) When you delete a comment, all nested comments will be marked as

deleted
.

3) You can override default CommentModel class by changing the property

commentModelClass
in the Comment Module.

4) You can implement your own methods

getAvatar
and
getUsername
in the
userIdentityClass
. Just create this methods in your User model. For example:
public function getAvatar()
{
    // your custom code
}

public function getUsername() { // your custom code }

Usage

Basic example: ```php // the model to which are added comments, for example: $model = Post::find()->where(['title' => 'some post title'])->one();

<?php echo \yii2mod\comments\widgets\Comment::widget([ 'model' => $model, ]); ?> ```

You can use your own template for render comments:

 $model,
    'commentView' => '@app/views/site/comments/index' // path to your template
]); ?>

Use the following code for multiple widgets on the same page: ```php <?php echo \yii2mod\comments\widgets\Comment::widget([ 'model' => $model, ]); ?>

<?php echo \yii2mod\comments\widgets\Comment::widget([ 'model' => $model2, 'formId' => 'comment-form2', 'pjaxContainerId' => 'unique-pjax-container-id' ]); ?> ```

To enable the pagination for comments list use the following code:

php
 $model,
      'dataProviderConfig' => [
          'pagination' => [
              'pageSize' => 10
          ],
      ]
]); ?>

Advanced example:

php
 $model,
      'relatedTo' => 'User ' . \Yii::$app->user->identity->username . ' commented on the page ' . \yii\helpers\Url::current(),
      'maxLevel' => 2,
      'dataProviderConfig' => [
          'pagination' => [
              'pageSize' => 10
          ],
      ],
      'listViewConfig' => [
          'emptyText' => Yii::t('app', 'No comments found.'),
      ],
]); ?>

Using Events

You may use the following events:

        'class' => 'yii2mod\comments\Module',
        'controllerMap' => [
            'default' => [
                'class' => 'yii2mod\comments\controllers\DefaultController',
                'on beforeCreate' => function ($event) {
                    $event->getCommentModel();
                    // your custom code
                },
                'on afterCreate' => function ($event) {
                    $event->getCommentModel();
                    // your custom code
                },
                'on beforeDelete' => function ($event) {
                    $event->getCommentModel();
                    // your custom code
                },
                'on afterDelete' => function ($event) {
                    $event->getCommentModel();
                    // your custom code
                },
            ]
        ]
    ]
