在数组和标题中使用PHP进行Wordpress术语创建

Question

So I'm trying to create two categories when the user logs in. I need the category names to be the username of the user who is logging in.

I'm fairly new to PHP and I've been looking through the Codex and I know how to get the user information but I can't figure out how to make it output in the array or as the title.

The current code below is the closest I've gotten. It all works except the PHP code is not outputting. It shows as blank after the creation process.

function Login_CreateInitialCategories($user_login, $user) {

    $current_user = wp_get_current_user();
    wp_insert_term(
        '<?php  echo $current_user->user_login; ?>',
        'outings',
        array(
          'description' => '<?php echo $current_user->user_login ; ?> Outings',
          'slug'        => '<?php echo $current_user->user_login ; ?>-category'
        )
    );

    wp_insert_term(
        '<?php echo $current_user->user_login ; ?>',
        'adventures',
        array(
          'description' => '<?php echo $current_user->user_login ; ?> Adventures',
          'slug'        => '<?php echo $current_user->user_login ; ?>-category'
        )
    );

}
add_action('wp_login', 'Login_CreateInitialCategories', 10, 2);

Do you guys know a way to get around this? The code is actually working perfectly, it's just not responding/outputting the PHP code.

Below is a link to a picture of the result of the code above. (I would of posted it here, but I don't have enough reputation.)

Okay, so after working on a solution I decided to get the meta value directly and that worked.

function Login_CreateInitialCategories() {
    $current_user = get_currentuserinfo();
    $user = get_user_meta($user_id = get_current_user_id(), nickname, true);
    wp_insert_term(
        $user, // the term 
        'outings', // the taxonomy
        array(
            'description'=> $user . ' Outings',
            'slug' => $user

  )
);

    wp_insert_term(
        $user, // the term 
        'adventures', // the taxonomy
        array(
            'description'=> $user . ' Adventures',
            'slug' => $user

  )
);  


}

add_action('wp_loaded', 'Login_CreateInitialCategories');
