How to use check_passwords action in WordPress

So, you’re interested in learning about the check_passwords action hook in WordPress? This hook fires before the password and confirm password fields are checked for congruity. It’s like a checkpoint to ensure everything matches up. Let’s dive in!

To use the check_passwords action, you first 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. 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 execute_on_check_passwords_event which takes 3 parameters and we registered using add_action. The first parameter check_passwords is the name of the hook. The second parameter execute_on_check_passwords_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 check_passwords action.

Parameters

Below are the 3 parameters required to use this hook:

• $user_login: (string) The username.
• $pass1: (string) The password (passed by reference).
• $pass2: (string) The confirmed password (passed by reference).

Live Example 1: Basic Usage

Here’s how you can use this hook:

    function weplugins_execute_on_check_passwords_event($user_login, $pass1, $pass2) {
        // 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_passwords", "weplugins_execute_on_check_passwords_event", 10, 3);
    

Live Example 2: Removing the Hook

To remove a hook callback, use the example below:

    remove_action("check_passwords", "weplugins_execute_on_check_passwords_event", 10, 3);
    

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

Live Example 3: Custom Functionality

Let’s say you want to log an event when passwords are checked:

    function weplugins_log_password_check($user_login, $pass1, $pass2) {
        error_log("Passwords checked for user: " . $user_login);
    }
    // add the action
    add_action("check_passwords", "weplugins_log_password_check", 10, 3);
