<h4>What is Slack?</h4>
<p><a href="https://slack.com/is" rel="nofollow ugc">Slack</a> is a team collaboration tool that offers chat rooms organized by topic, as well as private groups and direct messaging. It’s a great way to be productive with your team without clogging up your inbox.</p>
<h4>What is A Slackbot?</h4>
<p><a href="https://slack.zendesk.com/hc/en-us/articles/202026038-Slackbot-your-assistant-notepad-programmable-bot" rel="nofollow ugc">Slackbot</a> is Slack’s built-in robot, which helps us send messages to you and your team inside your Slack account.</p>
<h4>Why Rock The Slackbot?</h4>
<p>Because it can help you manage your websites, and stay on top of changes, by sending notifications (following numerous WordPress events) to your Slackbot who will pass them along to a channel or direct message in your Slack account.</p>
<p><strong>Rock the Slackbot is multisite-friendly.</strong></p>
<p><strong>Rock the Slackbot sends customizable notifications</strong> for the following events:</p>
<ul>
<li>When a post is published</li>
<li>When a post is unpublished</li>
<li>When a post is updated</li>
<li>When a post is deleted</li>
<li>When a post is trashed</li>
<li>When a comment is added</li>
<li>When a comment is approved</li>
<li>When a comment is unapproved</li>
<li>When a comment is marked as spam</li>
<li>When a comment is trashed</li>
<li>When a 404 error is thrown</li>
<li>When a menu item is deleted</li>
<li>When media is added</li>
<li>When media is edited</li>
<li>When media is deleted</li>
<li>When a user is added</li>
<li>When a user is deleted</li>
<li>When a user’s role is changed</li>
<li>When a plugin, theme, or core update is available</li>
<li>When a plugin, theme, or core is updated</li>
</ul>
<p><strong>I’m working to add the following events:</strong></p>
<ul>
<li>When menu item is added</li>
<li>When plugins or themes are uploaded</li>
<li>When plugins or themes are activated</li>
</ul>
<p><strong>Each event can be customized to allow you to send different event notifications to different Slack channels</strong>, e.g. you can send core, theme and plugin updates to your “wp-development” channel while all of your post changes go to your “wp-content” channel.</p>
<p>Please use <a href="https://github.com/bamadesigner/rock-the-slackbot/issues" rel="nofollow ugc">the Issues section of this plugin’s GitHub repo</a> to suggest features, like other notification events.</p>
<p><strong>A Slack account is required to use this plugin</strong> and is free to use for as long as you want and with an unlimited number of people. <a href="https://slack.com/" rel="nofollow ugc">Visit the Slack website</a> to learn more and sign up.</p>
<h3>Send A Simple Slack Message</h3>
<p>You can use the following send_webhook_message() function to send a simple message to your Slack account.</p>
<p><strong>The function accepts the following parameters:</strong></p>
<ol>
<li>$webhook_id_or_url – provide the webhook URL or the ID of one stored in settings</li>
<li>$message – the message you want to send</li>
<li>
<p>$channel – OPTIONAL – the channel you want to send message to. Prefix with # for a specific channel or @ for a specific user. Will use default channel if nothing is passed.</p>
<p>// Use this function to send a simple message to Slack<br />
rock_the_slackbot()->send_webhook_message( ‘564d3c1cdf52d’, ‘this is a test’, ‘#testchannel’ );</p>
<h3>Filters</h3>
<p>Rock The Slackbot has filters setup to allow you to tweak each WordPress notification before it’s sent. You can setup a filter for all notifications or drill down by event or specific webhook.</p>
</li>
</ol>
<p><strong>Each notification filter passes three arguments:</strong></p>
<ol>
<li>$notification – an array containing the notification information: webhook URL (the URL for your Slack account) and the payload (all of the information being sent to Slack) for the notification</li>
<li>$notification_event – the slug of the notification event
<ul>
<li>Will be false if you send a custom Slack notification that doesn’t involve a WordPress event</li>
</ul>
</li>
<li>$event_args – an array containing notification event specific information
<ul>
<li>Will be false if you send a custom Slack notification that doesn’t involve a WordPress event</li>
</ul>
</li>
</ol>
<p><strong>See <em>Notification Events</em> below to learn which information is passed to the filters for each notification event.</strong></p>
<h4>Filter all WordPress notifications</h4>
<pre><code>add_filter( 'rock_the_slackbot_notification', 'filter_rock_the_slackbot_notification', 10, 3 );
function filter_rock_the_slackbot_notification( $notification, $notification_event, $event_args ) {

    // Change the pieces

    // Return the notification
    return $notification;
}
</code></pre>
<h4>Filter WordPress notifications by webhook ID</h4>
<pre><code>// You can find the ID for each of your webhooks on their edit screen in the admin
add_filter( 'rock_the_slackbot_notification_(webhook_id)', 'filter_rock_the_slackbot_notification_webhook', 10, 3 );
function filter_rock_the_slackbot_notification_webhook( $notification, $notification_event, $event_args ) {

  // Change the pieces

  // Return the notification
  return $notification;
}
</code></pre>
<h4>Filter WordPress notifications by event slug</h4>
<pre><code>// The event slugs are listed below
add_filter( 'rock_the_slackbot_notification_(notification_event)', 'filter_rock_the_slackbot_notification_event', 10, 3 );
function filter_rock_the_slackbot_notification_event( $notification, $notification_event, $event_args ) {

  // Change the pieces

  // Return the notification
  return $notification;
}
</code></pre>
<h4>Filter all outgoing webhook payloads that are sent to Slack</h4>
<p>Whether it’s a WordPress notification or a simple Slack message, all messages to Slack are sent as a payload in an outgoing webhook. This filter allows you to change any payload sent to Slack in an outgoing webhook.</p>
<pre><code>add_filter( 'rock_the_slackbot_outgoing_webhook_payload', 'filter_rock_the_slackbot_outgoing_webhook_payload', 10, 2 );
function filter_rock_the_slackbot_outgoing_webhook_payload( $payload, $webhook_url ) {

<h3>Filter Examples</h3>
<p>You can use a filter to change the Slack notification to go to a different Slack channel according to post information, like the post category:</p>
<pre><code>add_filter( 'rock_the_slackbot_notification', 'filter_rock_the_slackbot_notification', 10, 3 );
function filter_rock_the_slackbot_notification( $notification, $notification_event, $event_args ) {

   // Only run filter for specific events
   switch ( $notification_event ) {

       // This way you can set which events you want to use
       case 'post_published':
       case 'post_unpublished':
       case 'post_updated':
       case 'post_deleted':
       case 'post_trashed':

           // Get category names
           $categories = wp_get_post_categories( $event_args[ 'post_id' ], array( 'fields' => 'names' ) );

           // Replace 'CategoryName' with the category you're looking for
           if ( in_array( 'CategoryName', $categories ) ) {

               // Change the channel in the payload
               // Make sure you prefix the channel name with #
               $notification[ 'payload' ][ 'channel' ] = '#newchannel';

           }
           break;
   }

   // Return the notification
   return $notification;
}

Rock The Slackbot

Thanks again. Trying to get the boss to buy you a few cups of coffee :)



Great UI...and it works!

Perfect integration for what I needed, and with the ability to ping certain updates to specific slack channels, it can be spammy or not.
My only wish would be to customize the post message content, but even then, I like what this is :)



Rock the Cat Box!

The plugin works really well, and what is more important for me as a developer - the code is really well handled, formatted and commented. I wish all the plugins in the Repo were done this way!



... and it's beautiful on the inside :)

My company's web presence is made up of 4 subsites, each with their own blogs.  Rock The Slackbot made it easy for me to automatically announce our new posts to a dedicated slack channel, so that the entire team is kept up-to-date on company news.  In addition, it notifies the technical team (in another channel) when a new version of WordPress core is available, and when there are plugins to be updated.

The plugin's configuration is easy to understand, and it just works.
