How to use comment_flood_message filter in WordPress

If you’re dealing with comment flood error messages and want to customize them, the comment_flood_message filter is your go-to solution! As an Indian developer, I’ve found this hook to be super useful for tailoring error messages to fit the unique needs of each project.

comment_flood_message filter

Filters the comment flood error message.

To use the comment_flood_message filter, first, you have to register it using add_filter. You can write this code into 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 below live example, we have defined a function weplugins_modify_comment_flood_message_defaults which takes one parameter and we registered it using add_filter. The first parameter comment_flood_message is the name of the hook, the second parameter weplugins_modify_comment_flood_message_defaults is the name of the function that 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 comment_flood_message filter.

Parameters

Below the one parameter is required to use this hook.

• $comment_flood_message: (string) Comment flood error message.

Live Examples

Basic Usage

Below is an example of how you can use this hook to customize the comment flood message.

function weplugins_modify_comment_flood_message_defaults($comment_flood_message) { 
    // Update the $comment_flood_message variable according to your website requirements and return this variable. 
    $comment_flood_message = 'You are posting comments too quickly. Slow down!';
    return $comment_flood_message; 
}
// add the filter
add_filter("comment_flood_message", "weplugins_modify_comment_flood_message_defaults", 10, 1);

Conditional Customization

Here’s how you can conditionally modify the comment flood message based on user roles.

function weplugins_modify_comment_flood_message_defaults($comment_flood_message) { 
    if (current_user_can('administrator')) {
        $comment_flood_message = 'Admins can post as fast as they like!';
    } else {
        $comment_flood_message = 'You are posting comments too quickly. Slow down!';
    }
    return $comment_flood_message; 
}
// add the filter
add_filter("comment_flood_message", "weplugins_modify_comment_flood_message_defaults", 10, 1);

Removing the Hook

To remove a hook callback, use the example below.

remove_filter("comment_flood_message", "weplugins_modify_comment_flood_message_defaults", 10, 1);

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