如果在 WooCommerce 的购物车页面上清空购物车，则重定向到商店 3+ [英] Redirect to shop if cart is emptied on cart page in WooCommerce 3+

问题描述

在 WooCommerce 中，我想在购物车为空时从购物车重定向到商店页面，并且我正在使用此代码:

In WooCommerce I want to redirect from cart to shop page when cart is empty and I am using this code:

function cart_empty_redirect_to_shop(){
    global $woocommerce;

    if ( is_page('cart') and !sizeof($woocommerce->cart->cart_contents) ) {
        wp_redirect( get_permalink( wc_get_page_id( 'shop' ) ) ); exit;
    }
}
add_action( 'wp_head', 'cart_empty_redirect_to_shop' );

此代码仅在购物车为空并且我尝试进入购物车页面时才有效.但是如果我已经在购物车页面上并且我删除了所有购物车项目，我必须重新加载页面才能重定向.所以我想我必须在代码中添加一些东西来重新加载页面.有什么想法吗?

This code works only if cart is empty and I try to go on cart page. But if I am already on cart page and I remove all cart items, I have to reload the page to get redirected. So I guess I have to add something in the code to reload the page. Any thoughts?

如果有人可以帮助我，我将不胜感激.

I would appreciate if anyone could help me with this.

推荐答案

自 WooCommerce 版本 3 以来，您的代码有点过时.现在在购物车页面上，PHP 重定向已无用，因为 清空购物车Ajax 客户现场活动.因此，在这种情况下，需要 Javascript (jQuery).

Your code is a bit obsolete since WooCommerce version 3. Now on cart page, PHP redirect is useless, because Emptying cart is an Ajax customer live event. So in this case Javascript (jQuery) is required.

改用以下内容，处理所有情况:

Use the following instead, that handle all cases:

add_action( 'template_redirect', 'empty_cart_redirection' );
function empty_cart_redirection(){
    if( is_cart() ) :
    
    // Here set the Url redirection
    $url_redirection = get_permalink( wc_get_page_id( 'shop' ) );
    
    // When trying to access cart page if cart is already empty  
    if( WC()->cart->is_empty() ){
        wp_safe_redirect( $url_redirection );
        exit();
    }
    
    // When emptying cart on cart page
    wc_enqueue_js( "jQuery(function($){
        $(document.body).on( 'wc_cart_emptied', function(){
            if ( $( '.woocommerce-cart-form' ).length === 0 ) {
                $(window.location).attr('href', '" . $url_redirection . "');
                return;
            }
        });
    });" );
    endif;
}

代码位于活动子主题(或活动主题)的functions.php 文件中.自第 3 版以来，已在所有 WooCommerce 版本中进行测试和工作.

Code goes in functions.php file of the active child theme (or active theme). Tested and works in all WooCommerce versions since version 3.
