You can use the login_redirect
hook.
function redirect_admin( $redirect_to, $request, $user ){
//is there a user to check?
if ( isset( $user->roles ) && is_array( $user->roles ) ) {
//check for admins
if ( in_array( 'administrator', $user->roles ) ) {
$redirect_to = WP_HOME.'/quote-list/'; // Your redirect URL
}
}
return $redirect_to;
}
add_filter( 'login_redirect', 'redirect_admin', 10, 3 );
Example taken from WordPress Codex
Also is_admin() does not check if the user is an administrator but if the administration panel is being displayed.
