Module setup

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

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

Comments management section setup

To access the comments management section, you need to add this to your application configuration:

  'controllerMap' => [
      'comments' => 'yii2mod\comments\controllers\ManageController'
  ]  

Basically the above code must be placed in the admin module

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

If you have added this controller in the module admin, the URL will look like the following http://localhost/path/to/index.php?r=admin/comments/index

Notes:

1. Delete button visible only for user with admin role.
2. When you delete a comment, all nested comments will be marked as deleted.
3. For change the any function in the CommentModel you can create your own model and change the property commentModelClass in the Comment Module.
4. You can implement your own function getAvatar in the userIdentityClass. Just create the getAvatar method in your User model, and return a image path.

public function getAvatar()
{
    // return some image path
}

Usage

Basic example:

<?php echo \yii2mod\comments\widgets\Comment::widget([
    'model' => $model,
    'relatedTo' => 'User ' . \Yii::$app->user->identity->username . ' commented on the page ' . \yii\helpers\Url::current(), // for example
    'maxLevel' => 3, // maximum comments level, level starts from 1, null - unlimited level. Defaults to `7`
    'showDeletedComments' => true // show deleted comments. Defaults to `false`.
]); ?>

You can use your own template for render comments:

<?php echo \yii2mod\comments\widgets\Comment::widget([
  'model' => $model,
  'commentView' => '@app/views/site/comments/index' //path to your template
]); ?>

Use the following code for multiple widgets on the same page:

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

echo \yii2mod\comments\widgets\Comment::widget([
      'model' => $model2,
      'formId' => 'comment-form2',
      'pjaxContainerId' => 'unique-pjax-container-id' // also you can set the `pjaxContainerId`
  ]);
