• Activate the plugin in the config/ProjectConfiguration.class.php

<?php
class ProjectConfiguration extends sfProjectConfiguration
{
  public function setup()
  {
    ...
    $this->enablePlugins('...', 'sfNestedCommentPlugin');
    ...
  }
}

• Publish the plugin's assets

> ./symfony plugin:publish-assets

Add the behavior in your schema. Example:

<table name="post">
  <column name="id" required="true" primaryKey="true" autoIncrement="true" type="INTEGER" />
  <column name="title" type="VARCHAR" required="true" primaryString="true" />
  <column name="content" type="LONGVARCHAR" required="true" />
  <behavior name="commentable" />
</table>

Rebuild your model:

> ./symfony propel:build --all-classes

In myUser.class.php (frontend and backend application), you have to define the following functions (for the current logged on user):

• getAuthorId() : Author Id,
• getAuthorName() : Author Name,
• getAuthorEmail() : Author Email,
• getAuthorWebsite() : Author Website.

First, activate the module in the settings.yml (apps/your_frontend_app/config/settings.yml)

enabled_modules: [..., sfNestedComment]

This plugin comes with two components.

This component is used to display the most recent comments. In your template:

<?php include_component('sfNestedComment', 'recentComments') ?>

The number of comments displayed in this component is controlled by max_recent setting. In order to make your recent comments clickable, you have to define the url_commentable_method.

all:
  sfNestedComment:
    url_commentable_method: [myTools, generatePostUri]

Example:

<?php
public static function generatePostUri($post, $postfix = null, $action = 'show')
{
  if (sfConfig::get('app_sfSimpleBlog_use_date_in_url', false))
  {
    $publishedAt = strtotime($post->getPublishedAt());
    return 'sfSimpleBlog/' . $action . '?' .
      'year='.date('Y', $publishedAt) .
      '&month='.date('m', $publishedAt) .
      '&day='.date('d', $publishedAt) .
      '&stripped_title='.$post->getStrippedTitle() .
      $postfix;
  }
  else
  {
    return 'sfSimpleBlog/' . $action . '?stripped_title=' . $post->getStrippedTitle().$postfix;
  }
}

By default, the titles in the recent comments are truncated to 25. You can change it by change the value of recent_max_title_length.

all:
  sfNestedComment:
    recent_max_title_length: 30

This component is used to display the commentable object's comments and comment form. In your template:

<?php include_component('sfNestedComment', 'showComments', array('object' => $post)) ?>

By default, the comments is displayed in the nested fashion, and it is controlled by max_depth setting. You can disabled this feature by set the max_depth to 0.

all:
  sfNestedComment:
    max_depth: 0

When the user post a comment, the request is done via Ajax. You can disable it by set the use_ajax to false.

all:
  sfNestedComment:
    use_ajax: false

If you want to integrate recaptcha, enabled the recaptcha setting in your app.yml. Note, this setting require sfFormExtraPlugin

all:
  recaptcha:
    enabled: true
    # visit http://recaptcha.net/
    public_key:     your_public_recaptcha_key
    private_key:    your_private_recaptcha_key

To disabled comment per commentable object, your object must provide allowComments() function.

<?php
public function allowComments()
{
  return false;
}

Gravatar is enabled by default, and it is depends on sfGravatarPlugin, to disable it

all:
  sfNestedComment:
    use_gravatar: false

Activate the module in the settings.yml (apps/your_backend_app/config/settings.yml)

enabled_modules:        [..., sfNestedCommentAdmin]

In order this feature to work, your object (commentable object) must provide following functions:

• __toString(). example: title of post.
• getAuthorEmail(). The email to receive an incoming comment.

<?php
public function getAuthorEmail()
{
  return $this->getAuthor()->getEmail();
}

There are several options you may consider when you enabled Email notification:

• mail_alert. This setting used to enabled email notification. Possible values are:

  • true: send an email for every posted comment
  • moderated: send an email for every automoderated comment
  • false: disable mail notification

• automoderation. Possible values are:

  • true: comments are not published until a moderator accepts them
  • first_post: the first comment of a user must be accepted, subsequent posts are accepted automatically
  • false: comments are automatically accepted and published

• from_email. email sender

• max_attempts. How many times the mail delivery should be attempted before flagging it as failed

In the case you want to enable messages spooling, you can use the class provided by this plugin. In the factories.yml

mailer:
param:
  transport:
    class: Swift_SmtpTransport
    param:
      host:          smtp.gmail.com
      port:          465
