How to use comment_duplicate_trigger action in WordPress

comment_duplicate_trigger action

Fires immediately after a duplicate comment is detected.

To use the comment_duplicate_trigger 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_duplicate_trigger_event which takes 1 parameter and we registered it using add_action. The first parameter comment_duplicate_trigger is the name of the hook, the second parameter weplugins_execute_on_comment_duplicate_trigger_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_duplicate_trigger action.

Parameters

Below the 1 parameter is required to use this hook.

• $commentdata : (array) Comment data.

Live Example

Example 1: Triggering the Hook

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

Example 2: Using the Hook

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

function weplugins_execute_on_comment_duplicate_trigger_event($commentdata){
   // 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( "comment_duplicate_trigger", "weplugins_execute_on_comment_duplicate_trigger_event" , 10, 1);

Example 3: Removing the Hook

To remove a hook callback, use the example below.

remove_action( "comment_duplicate_trigger", "weplugins_execute_on_comment_duplicate_trigger_event", 10, 1 );

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