How to use comment_loop_start action in WordPress

comment_loop_start action

Fires once the comment loop is started.

To use the comment_loop_start action, first, you have to register it using add_action. 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 below live example, we have defined a function weplugins_execute_on_comment_loop_start_event and we registered it using add_action. The first parameter comment_loop_start is the name of the hook, the second parameter weplugins_execute_on_comment_loop_start_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 the comment_loop_start action.

Example 1: Basic Hook Usage

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

    function weplugins_execute_on_comment_loop_start_event(){
        // You can write code here to be executed when this action occurs in WordPress website according to your requirements.
    }
    // add the action
    add_action( "comment_loop_start", "weplugins_execute_on_comment_loop_start_event");
    

Example 2: Removing a Hook Callback

To remove a hook callback, use the example below.

    remove_action( "comment_loop_start", "weplugins_execute_on_comment_loop_start_event");
    

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

Example 3: Logging Comment Loop Start

Here’s how you can log the start of the comment loop for debugging purposes.

    function weplugins_log_comment_loop_start(){
        error_log('Comment loop has started.');
    }
    add_action( "comment_loop_start", "weplugins_log_comment_loop_start");
