# WordPress new comment notifications on your phone

> Get a push notification when someone comments on your WordPress site, with a button straight to the moderation queue when it needs approval.

- Company: WordPress (https://www.justpush.io/recipes/wordpress)
- Event: `comment.created` (New comment)
- Tags: Websites, Content
- Install: https://studio.justpush.io/recipes/wordpress/new-comment
- Web page: https://www.justpush.io/recipes/wordpress/new-comment

## Setup

1. Click Install in Studio and sign in. The recipe is added to your account and you get a personal webhook URL.
2. Copy the PHP snippet from the setup notes below. It already contains your endpoint URL.
3. Save it as a new .php file in wp-content/mu-plugins/ on your site (create the folder if it doesn't exist).
4. WordPress loads it automatically. Trigger a New comment to test.
5. WordPress doesn't send webhooks by itself, so this recipe comes with a small **must-use plugin**. Save the code below as `wp-content/mu-plugins/justpush-new-comment.php` (create the `mu-plugins` folder if it doesn't exist). WordPress loads files there automatically; there's nothing to activate.
6. ```php
7. <?php
8. /**
9. Plugin Name: JustPush — New comment
10. Description: Sends a push through JustPush Studio when a new comment is posted.
11. */
12. add_action('comment_post', function ($comment_id, $approved) {
13. // Spam and trashed comments aren't worth a push.
14. if ($approved === 'spam' || $approved === 'trash') {
15. return;
16. }
17. $comment = get_comment($comment_id);
18. // Real comments only, not pingbacks or trackbacks.
19. if (!$comment || !in_array($comment->comment_type, array('comment', ''), true)) {
20. return;
21. }
22. $pending = (string) $approved !== '1';
23. wp_remote_post('your webhook URL (shown in Studio after install)', array(
24. 'blocking' => false, // don't slow the page down waiting for JustPush
25. 'timeout'  => 3,
26. 'headers'  => array('Content-Type' => 'application/json'),
27. 'body'     => wp_json_encode(array(
28. 'event'      => 'comment.created',
29. 'site'       => get_bloginfo('name'),
30. 'status'     => $pending ? 'pending' : 'approved',
31. 'author'     => $comment->comment_author,
32. 'post_title' => get_the_title($comment->comment_post_ID),
33. 'excerpt'    => wp_trim_words($comment->comment_content, 20),
34. 'url'        => $pending
35. ? admin_url('edit-comments.php?comment_status=moderated')
36. : get_comment_link($comment),
37. )),
38. ));
39. }, 10, 2);
40. ```
41. To stop the notifications, delete the file.

## Code

Studio calls `handleRequest(request)` with the incoming webhook (`{ method, headers, body, query, raw }`) and sends the message object it returns. Returning `null` sends nothing.

```js
// WordPress → new comment
// Fires when the "JustPush — New comment" mu-plugin (see INSTALL.md) reports a
// "comment.created" event. WordPress has no webhooks of its own, so the snippet sends them.

// The snippet sends plain strings; treat blanks as missing.
function text(value) {
    return typeof value === "string" && value.trim() ? value.trim() : null
}

// Only link to real http(s) URLs.
function link(url, cta) {
    return typeof url === "string" && /^https?:\/\//.test(url) ? [{ cta, url }] : []
}

function handleRequest(request) {
    const event = request.body

    // Guard: only handle this recipe's event, so other snippets on this integration stay quiet.
    if (event?.event !== "comment.created") {
        console.log(`Ignoring WordPress event "${event?.event ?? "unknown"}"`)
        return null
    }

    const pending = event.status === "pending"
    const author = text(event.author) ?? "Someone"
    const on = text(event.post_title) ? ` on "${text(event.post_title)}"` : ""
    const excerpt = text(event.excerpt) ? `: ${text(event.excerpt)}` : ""

    return {
        title: pending ? "💬 Comment awaiting approval" : "💬 New comment",
        message: `${author}${on}${excerpt}`,
        topic: "WordPress",
        priority: pending ? 0 : -1, // Normal when it needs you, Low when it's already live
        buttons: link(event.url, pending ? "Moderate" : "View comment"),
    }
}
```

## WordPress comment.created webhook payload (sample)

```json
{
  "url": "https://example.com/wp-admin/edit-comments.php?comment_status=moderated",
  "site": "My Site",
  "event": "comment.created",
  "author": "Mark",
  "status": "pending",
  "excerpt": "Tip four changed my mornings. Do you have one for shared inboxes?",
  "post_title": "Ten tips for a calmer inbox"
}
```
