 * You would have to read the role of the user and decide depending on it. Here 
   you can find an example in the 1st answer: [https://stackoverflow.com/questions/36720949/get-user-role-by-id-wordpress](https://stackoverflow.com/questions/36720949/get-user-role-by-id-wordpress)

 * Please show _your _code so that one can tell you what you have written wrong 
   there. So you would also learn something instead of simply taking over finished.

 *     ```
       add_action('wp_login', 'myfunc');
   
       function myfunc() {
   
           $user_meta = get_userdata($user_id);
           $user_roles = $user_meta->roles;
           if (in_array("administartor", $user_roles)){
   
       	//run a code
   
       }
       }
       ```
   
 * i use this one but my login page is breaking Down and all login tries got failed
   message.
    I guess the problem is in **wp_login hook**

 * The error is actually how you use the hook. Check the manual: [https://developer.wordpress.org/reference/hooks/wp_login/](https://developer.wordpress.org/reference/hooks/wp_login/)
 * It says that the hook has 2 parameters: `$user_login` and `$user` – you ignore
   them completely and try to retrieve user data with a non-existing variable `$
   user_id`.
 * The correct way would be to call the hook correctly:
 * `add_action('wp_login', 'myfunc', 10, 2 );`
 * Then adjust the function call accordingly:
 * `function myfunc( $user_login, $user ) {`
 * and then you can query the user by his ID:
 * `$user_meta = get_userdata($user->ID);`
 * Also note that you have a misspelling of “administartor” below. But this doesn’t
   matter for your problem, you should only fix it if you want to get further.
