Redirect customer to login page (with other signup plugin) if user not logged in when proceeding to checkout

I find and use below code for when user in cart page and cart not empty: add_filter(‘woocommerce_get_checkout_url’, ‘dj_redirect_checkout’); function dj_redirect_checkout($url) { global $woocommerce; if(is_cart() && !is_user_logged_in() ){ $checkout_url=”digits login url”; } else{ $checkout_url=”https://yoursite.com/checkout/”; } return $checkout_url; }

Hata!: SQLSTATE[HY000] [1045] Access denied for user 'divattrend_liink'@'localhost' (using password: YES)
