Php 在 WooCommerce 中继续结帐时如何清除通知

发布于06月24日

如果订单少于1kg，我将使用以下代码在购物车页面上添加通知.

// Add notice on cart when order is less than 1kg
add_action('woocommerce_check_cart_items','check_cart_minweight');
 
function check_cart_minweight(){
    global $woocommerce;

    $minweight = $woocommerce->cart->cart_contents_weight;

    if( $minweight < 1 ){ 
        wc_add_notice( sprintf( __( 'You have selected %sKg, add more items, orders over 1kg get free shipping', 'woocommerce' ), $minweight ), 'success' );
    }
}

问题是，如果客户体重没有超过1公斤(很多时候他们没有)，并且继续结帐，那么结帐时通知就不清楚了.有什么建议可以防止这种情况发生吗？

推荐答案

有几种 Select .例如，您可以确保代码不会在签出页面上执行:

function action_woocommerce_check_cart_items() {
    // NOT for checkout page
    if ( is_checkout() ) return;

    // Get total weight
    $total_weight = WC()->cart->get_cart_contents_weight();

    // Less
    if ( $total_weight < 1 ) { 
        wc_add_notice( sprintf( __( 'You have selected %sKg, add more items, orders over 1kg get free shipping', 'woocommerce' ), $total_weight ), 'notice' );
    }
}   
add_action( 'woocommerce_check_cart_items' , 'action_woocommerce_check_cart_items', 10 );

另一个选项是确保在满足条件之前无法访问签出页面:

function action_woocommerce_check_cart_items() {
    // Get total weight
    $total_weight = WC()->cart->get_cart_contents_weight();

    // Less
    if ( $total_weight < 1 ) { 
        wc_add_notice( sprintf( __( 'You have selected %sKg, add more items, orders over 1kg get free shipping', 'woocommerce' ), $total_weight ), 'error' );

        // Remove proceed to checkout button
        remove_action( 'woocommerce_proceed_to_checkout', 'woocommerce_button_proceed_to_checkout', 20 );
    }
}   
add_action( 'woocommerce_check_cart_items' , 'action_woocommerce_check_cart_items', 10 );
