我遇到了这段代码,该代码用于在某些页面加载时清除Woocommerce购物车.

但是,我想知道有没有办法在购物车被抛弃后对其进行清理？

For triggering only on front page your function needs to look like this:

add_action( 'init', 'woocommerce_clear_cart_url' );
function woocommerce_clear_cart_url() {
global $woocommerce;

if ( is_front_page() && isset( $_GET['empty-cart'] ) ) { 
    $woocommerce->cart->empty_cart(); 
}

}
function is_front_page() returns true only on front page of your wordpress site. Also, you might detect any other page with function is_page() where you can pass any page title, ID or slug

来自这个问题：Set WooCommerce Cart Expiration

From what I can see, WooCommerce 2.0.20 has a scheduled maintenance job that runs twice/day that will remove any cart sessions from the WordPress options table. The default expiration time is set to 48 hours from the time the user first created the cart. I’m guessing your standard WordPress scheduling routines (and server cron/at jobs) will need to be running properly for this to execute.

AFAIK there is no way to adjust the 48 hour rule via settings. You could write a filter in your theme or in an “adjacent” plugin.

我对代码进行了一些调整,以切换到24小时课程.我不确定您是否希望每隔几分钟删除一次,因为这可能会导致性能提高.

add_filter('wc_session_expiring', 'so_26545001_filter_session_expiring' );

function so_26545001_filter_session_expiring($seconds) {
    return 60 * 60 * 23; // 23 hours
}

add_filter('wc_session_expiration', 'so_26545001_filter_session_expired' );

function so_26545001_filter_session_expired($seconds) {
    return 60 * 60 * 24; // 24 hours
}
