Php 以编程方式从购物车中删除应用的特定费用

我已通过以下方式向我的WooCommerce购物车申请了特定费用：

WC()->cart->add_fee( __( "Delivery Fee"), 50);

上面的代码所做的是，除了小计和运费之外，它还将送货费添加到总数中，并正确显示总计

我现在想以编程方式删除申请的费用，但我无法这样做

我试过这个，但不起作用：

WC()->cart->remove_fees( __( "Delivery Fee"));

add_action( 'woocommerce_before_cart', 'custom_fees' );
function custom_fees() {
    // Add Fees - This WORKS
    WC()->cart->add_fee( __( "Delivery Fee"), 50);

    // Remove Fees - This DOES NOT WORK
    WC()->cart->remove_fees( __( "Delivery Fee"));
}

这是我的完整代码：

WC()->cart->remove_fees( __( "Delivery Fee"));

add_action( 'woocommerce_before_cart', 'custom_fees' );
function custom_fees() {
    // Add Fees - This WORKS
    WC()->cart->add_fee( __( "Delivery Fee"), 50);

    // Remove Fees - This DOES NOT WORK
    WC()->cart->remove_fees( __( "Delivery Fee"));
}

如何在不必清除购物车的情况下以编程方式删除申请的费用？

取决于您的需要，这里有一个解决方案：

add_action( 'woocommerce_before_calculate_totals', 'custom_fees' );
function custom_fees() {
    // Add Fees - This WORKS
    WC()->cart->add_fee( __( "Delivery Fee"), 50); // gets removed
    WC()->cart->add_fee( __( "Delivery Fee2"), 150); // will not be removed.

    $fees = WC()->cart->get_fees();
    foreach ($fees as $key => $fee) {
        if($fees[$key]->name === __( "Delivery Fee")) {
            unset($fees[$key]);
        }
    }
    WC()->cart->fees_api()->set_fees($fees);
}

根据您的需要，这里有一个解决方案：

add_action( 'woocommerce_before_calculate_totals', 'custom_fees' );
function custom_fees() {
    // Add Fees - This WORKS
    WC()->cart->add_fee( __( "Delivery Fee"), 50); // gets removed
    WC()->cart->add_fee( __( "Delivery Fee2"), 150); // will not be removed.

    $fees = WC()->cart->get_fees();
    foreach ($fees as $key => $fee) {
        if($fees[$key]->name === __( "Delivery Fee")) {
            unset($fees[$key]);
        }
    }
    WC()->cart->fees_api()->set_fees($fees);
}
