基于购物车的 WooCommerce 登录重定向

WooCommerce login redirect based on cart

我想申请以下2个案例:

我的代码:

 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');

以上代码适用于我的第一个案例。但是对于我的第二种情况,当我使用 if ( sizeof( $woocommerce->cart->cart_contents ) == 0 ) {} 检查购物车时,我的网站停止工作。

我已将此代码添加到我主题的 functions.php 文件中。

我做错了什么?

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.

这是您需要的代码:

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') ) );
}

代码进入您的活动子主题的 function.php 文件。 已测试并有效。
