More information

See WordPress Developer Resources: do_all_pingbacks()
This function is available since WordPress version 2.1. It is not deprecated and you can find its source code in the wp-includes/comment.php file.

Examples

Performing all pending pingbacks

If you want to manually trigger all pending pingbacks, simply call the function:

do_all_pingbacks();

This will perform all pingbacks that are queued in your WordPress.

Perform pingbacks on a schedule

If you want to perform pingbacks at a specific time, you can use this function inside a WordPress scheduled event:

if (!wp_next_scheduled('my_custom_pingbacks')) {
    wp_schedule_event(time(), 'daily', 'my_custom_pingbacks');
}

add_action('my_custom_pingbacks', 'do_all_pingbacks');

This code sets up a daily event that triggers the do_all_pingbacks() function.

Perform pingbacks when publishing a new post

You might want to perform all pingbacks when a new post is published. You can do this with the ‘publish_post’ action hook:

add_action('publish_post', 'do_all_pingbacks');

This code will perform all pingbacks each time a new post is published.

Perform pingbacks when a comment is approved

You can also perform all pingbacks when a comment is approved using the ‘comment_unapproved_to_approved’ action:

add_action('comment_unapproved_to_approved', 'do_all_pingbacks');

This will trigger all pingbacks whenever a comment changes status from unapproved to approved.

Perform pingbacks with a custom button in admin panel

You can create a custom button in the WordPress admin panel that when clicked, will perform all pingbacks:

add_action('admin_notices', 'custom_pingback_button');

function custom_pingback_button() {
    echo '<a href="' . add_query_arg('pingback', 'true') . '" class="button">Perform Pingbacks</a>';
}

if (isset($_GET['pingback'])) {
    do_all_pingbacks();
}

This code adds a button to the admin panel. When you click this button, the do_all_pingbacks() function is triggered.
