Function and usage of get_to_ping() in wordpress


Answers ( 1 )


    The get_to_ping() function in WordPress is designed to retrieve a list of URLs that need to be pinged for a specific post. Pinging is a process used to notify search engines and other web services when your blog content is updated, which can help with the indexing of new content.

    Here's a detailed explanation of the function and its usage:

    Function Signature

    get_to_ping( int|WP_Post $post ): string[]|false


    • $post (int | WP_Post) [required]: This parameter can be either a Post ID (integer) or a post object (WP_Post). It specifies the post for which you want to retrieve the URLs to be pinged.

    Return Value

    • string[]|false: The function returns an array of URLs that are yet to be pinged for the specified post. If there are no URLs to ping or if the post does not exist, it returns false.

    Function Description

    The get_to_ping() function is used to get a list of URLs that are associated with a specific post and are queued to be pinged. Pinging is used to inform other websites and services that your content has been updated or changed. This function is particularly useful if you are implementing a custom pinging mechanism or want to inspect which URLs are queued for pinging in relation to a specific post.

    Sample Usage

    Here is an example of how to use the get_to_ping() function:

    $post_id = 123; // Replace with your specific Post ID
    $urls_to_ping = get_to_ping( $post_id );
    if ( is_array( $urls_to_ping ) ) {
        echo "URLs to ping for post ID $post_id:\n";
        foreach ( $urls_to_ping as $url ) {
            echo $url . "\n";
    } else {
        echo "No URLs to ping for this post or post does not exist.";

    In this example, get_to_ping() is called with a specific post ID. The function returns an array of URLs that are yet to be pinged for this post. The script then iterates over the array and prints out each URL. If there are no URLs to ping or the post does not exist, a message is displayed instead.


    • The function is part of WordPress's broader ping/trackback functionality, which is an integral part of how WordPress interacts with other sites on the web.
    • It is mostly used in the context of WordPress's internal mechanisms or by plugins that modify or extend WordPress's ping/trackback capabilities.
    • Custom usage of this function should be handled with care to avoid unintended behaviors, especially in a production environment.
