How to use pre_wp_update_comment_count_now filter in WordPress

pre_wp_update_comment_count_now filter

Filters a post’s comment count before it is updated in the database.

To use the pre_wp_update_comment_count_now filter, you first have to register it using add_filter. You can write this code into the functions.php of your activated theme or in a custom WordPress Plugin.

We at WePlugins always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress theme in the future.

In the example below, we have defined a function weplugins_modify_pre_wp_update_comment_count_now_defaults which takes 3 parameters and we registered it using add_filter. The first parameter pre_wp_update_comment_count_now is the name of the hook, the second parameter weplugins_modify_pre_wp_update_comment_count_now_defaults is the name of the function which needs to be called, the third parameter is the priority of calling the hook if the same hook is used multiple times, and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometimes, you have to remove a registered hook so you can use remove_filter to remove the pre_wp_update_comment_count_now filter.

Parameters

Below are the 3 parameters required to use this hook.

• $new: (int|null) The new comment count. Default null.
• $old: (int) The old comment count.
• $post_id: (int) Post ID.

Live Example

Example 1: Basic Usage

Below is an example of how you can use this hook.

    function weplugins_modify_pre_wp_update_comment_count_now_defaults($new, $old, $post_id) {
        // Update the $new variable according to your website requirements and return this variable. You can modify the $new variable conditionally too if you want.
        return $new;
    }
    // add the filter
    add_filter("pre_wp_update_comment_count_now", "weplugins_modify_pre_wp_update_comment_count_now_defaults", 10, 3);
    

Example 2: Conditional Comment Count Update

In this example, we conditionally update the comment count based on the post ID.

    function weplugins_modify_pre_wp_update_comment_count_now_defaults($new, $old, $post_id) {
        if ($post_id == 123) {
            $new = $old + 10; // Add 10 comments for post ID 123
        }
        return $new;
    }
    // add the filter
    add_filter("pre_wp_update_comment_count_now", "weplugins_modify_pre_wp_update_comment_count_now_defaults", 10, 3);
    

Example 3: Removing the Hook

To remove a hook callback, use the example below.

    remove_filter("pre_wp_update_comment_count_now", "weplugins_modify_pre_wp_update_comment_count_now_defaults", 10, 3);
    

Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.
