How to use check_comment_flood action in WordPress

check_comment_flood action

Allows checking for comment flooding.

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

At WePlugins, we 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 below live example, we have defined a function weplugins_execute_on_check_comment_flood_event which takes 4 parameters and we registered using add_action. The first parameter check_comment_flood is the name of the hook, The second parameter weplugins_execute_on_check_comment_flood_event 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_action to remove check_comment_flood action.

Parameters

Below are the 4 parameters required to use this hook.

• $comment_author_IP : (string) Comment author’s IP address.
• $comment_author_email : (string) Comment author’s email.
• $comment_date_gmt : (string) GMT date the comment was posted.
• $wp_error : (bool) Whether to return a WP_Error object instead of executing wp_die() or die() if a comment flood is occurring.

Live Examples

Basic Hook Registration

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

    function weplugins_execute_on_check_comment_flood_event($comment_author_IP, $comment_author_email, $comment_date_gmt, $wp_error){
       // You can write code here to be executed when this action occurs in WordPress. Use the parameters received in the function arguments & implement the required additional custom functionality according to your website requirements.
    }
    // Add the action
    add_action( "check_comment_flood", "weplugins_execute_on_check_comment_flood_event" , 10, 4);
    

Removing the Hook Callback

To remove a hook callback, use the example below.

    remove_action( "check_comment_flood", "weplugins_execute_on_check_comment_flood_event", 10, 4 );
    

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

Custom Implementation Example

Here’s an example of a custom implementation where we log the comment author’s email whenever a comment flood is detected.

    function weplugins_custom_check_comment_flood($comment_author_IP, $comment_author_email, $comment_date_gmt, $wp_error){
       if($wp_error){
           error_log("Comment flood detected from: " . $comment_author_email);
       }
    }
    // Add the action
    add_action( "check_comment_flood", "weplugins_custom_check_comment_flood" , 10, 4);
