WooCommerce login redirect based on cart

问题:

I want to apply following 2 case :

• If User not logged in and cart is empty: Then redirect user to login and then my account
• If User not logged in and cart has product: Then redirect user to login and after login redirect to checkout

My Code :

 function wpse_Nologin_redirect() {

    if (
        ! is_user_logged_in()
        && (is_checkout())
    ) {
        // feel free to customize the following line to suit your needs
        $MyLoginURL = "http://example.in/my-account/";
        wp_redirect($MyLoginURL);
        exit;
    }
}
add_action('template_redirect', 'wpse_Nologin_redirect');

Above code is working fine for my first case. But for my second case, when I check cart with if ( sizeof( $woocommerce->cart->cart_contents ) == 0 ) {}, my site stops working.

I have added this code in my theme's functions.php file.

What I am doing wrong?

To avoid your site to be off, global $woocommerce; is missing.
Now global $woocommerce; with $woocommerce->cart is now simply replaced by WC()->cart.

To check if cart is empty, you should use WC()->cart->is_empty(), as is_empty() is a conditional method of WC_cart class.

After, on checkout page (in both cases) if user is not logged in, you want to redirect him to my_account page (login/create account area).

Now on my_account page, when a logged user has something in his cart, you want to redirect him on checkout page.

Here is the code you need:

add_action('template_redirect', 'woocommerce_custom_redirections');
function woocommerce_custom_redirections() {
    // Case1: Non logged user on checkout page (cart empty or not empty)
    if ( !is_user_logged_in() && is_checkout() )
        wp_redirect( get_permalink( get_option('woocommerce_myaccount_page_id') ) );

    // Case2: Logged user on my account page with something in cart
    if( is_user_logged_in() && ! WC()->cart->is_empty() && is_account_page() )
        wp_redirect( get_permalink( get_option('woocommerce_checkout_page_id') ) );
}

Code goes in function.php file of your active child theme. Tested and works.
