如果超过5磅，WooCommerce免费送货

Question

我试图编写一个函数，如果订单超过5磅(80盎司)，则仅提供免费送货(删除所有其他选项)，但它不工作，尽管代码似乎正确。

这是我的:

  // Hide ALL shipping options but FREe when over 80 ounches (5 pounds)
add_filter( 'woocommerce_available_shipping_methods', 'ship_free_if_over_five_pounds' , 10, 1 );
/**
* Hide ALL Shipping option but free if over 5 pounds
*
* @param array $available_methods
*/
function ship_free_if_over_five_pounds( $available_methods ) {
    global $woocommerce;
    $whats_the_weight = $woocommerce->cart->cart_contents_weight;   
    if($whats_the_weight != 80) :
        // Get Free Shipping array into a new array
        $freeshipping = array();
        $freeshipping = $available_methods['free_shipping'];
        // Empty the $available_methods array
        unset( $available_methods );
        // Add Free Shipping back into $avaialble_methods
        $available_methods = array();
        $available_methods[] = $freeshipping;
    endif;
    return $available_methods;
}

任何想法吗?

代码是基于示例#19在这个网站上:

我知道这是一个老问题，但我最近有这个选择…

首先，在代码中"如果订单超过5磅(80盎司)"你的 if 语句应该是 if($whats_the_weight > 80) 而不是 != .但是我认为你的代码有点过时，如果你使用WooCommerce 2.6+。

在使用$woocommerce->cart->cart_contents_weight;代替global $woocommerce;之后，您可以使用: WC()->cart->cart_contents_weight;

我有这个更近期的代码片段基于这个官方线程WooCommerce 2.6+。你应该试试:

add_filter( 'woocommerce_package_rates', 'my_hide_shipping_when_free_is_available', 100 );
function my_hide_shipping_when_free_is_available( $rates ) {
    $cart_weight = WC()->cart->cart_contents_weight; // Cart total weight
    $free = array();
    foreach ( $rates as $rate_id => $rate ) {
        if ( 'free_shipping' === $rate->method_id && $cart_weight > 80 ) { // <= your weight condition
            $free[ $rate_id ] = $rate;
            break;
        }
    }
    return ! empty( $free ) ? $free : $rates;
}

对于WooCommerce 2.5，你应该试试这个:

add_filter( 'woocommerce_package_rates', 'hide_shipping_when_free_is_available', 10, 2 );
function hide_shipping_when_free_is_available( $rates, $package ) {
    $cart_weight = WC()->cart->cart_contents_weight; // Cart total weight
    // Only modify rates if free_shipping is present
    if ( isset( $rates['free_shipping'] ) && $cart_weight > 80 ) { // Here your weight condition
        // To unset a single rate/method, do the following. This example unsets flat_rate shipping
        unset( $rates['flat_rate'] );
        // To unset all methods except for free_shipping, do the following
        $free_shipping          = $rates['free_shipping'];
        $rates                  = array();
        $rates['free_shipping'] = $free_shipping;
    }
    return $rates;
}
