Add Username to URL for redirect

Question

I need a little help with what I believe would be PHP.

http://www.domain.com/author/username/achievements/

Depending on the username of the person logged in, I would like to create a URL that redirects a user to the aforementioned page. To do this, username needs to be replaced with their logged in username.

Is there an easy way to do this?

Answer 1

WordPress has several functions for getting user information, for example the following ones:

• get_currentuserinfo()
• get_userdata()
• wp_get_current_user()

Answer 2

You can use wp_get_current_user()
This should do the trick:

$current_user = wp_get_current_user();
if ( is_user_logged_in() ) {
    wp_redirect( 'http://www.domain.com/author/'.$current_user->user_login.'/achievements/');  
    exit;
} else {
    echo 'You have no business being here';
}

Also see the wp_get_current_user() documentation.

If you run in a:Warning: Cannot modify header information - headers already sent by

Add this to your functions.php:

add_action('init', 'do_output_buffer');
function do_output_buffer() {
    ob_start();
}
