按成本升序对 WooCommerce 运输选项进行排序，最后免费送货

Question

我正在尝试对 woocommerce 运输选项进行排序。我想按从低到高的价格排序，但我最后需要免运费选项。

我在 WooCommerce: Sort Shipping Costs from Low to High

工作

如何把 0 放在最后？

add_filter( 'woocommerce_package_rates' , 'businessbloomer_sort_shipping_methods', 10, 2 );
   
function businessbloomer_sort_shipping_methods( $rates, $package ) {
    
    if ( empty( $rates ) ) return;
   
    if ( ! is_array( $rates ) ) return;
    
    uasort( $rates, function ( $a, $b ) { 
        if ( $a == $b ) return 0;
        return ( $a->cost < $b->cost ) ? -1 : 1; 
    } );
    
    return $rates;
   
    // NOTE: BEFORE TESTING EMPTY YOUR CART
       
}

以下将按成本从低到高对运输选项进行排序，零成本和空运成本最后。

add_filter( 'woocommerce_package_rates' , 'sort_shipping_method_by_cost_zero_empty_cost_last', 10, 2 );
function sort_shipping_method_by_cost_zero_empty_cost_last( $rates, $package ) {
    if ( empty( $rates ) || ! is_array( $rates ) ) return;

    // Sort shipping methods based on cost
    uasort( $rates, function ( $a, $b ) {
        if ( $a == $b ) return 0;
        return ( $a->cost < $b->cost ) ? -1 : 1;
    } );

    $free = $zero = []; // Initializing

    // Loop through shipping rates
    foreach ( $rates as $rate_key => $rate ) {
        // For "free shipping" methods
        if ( 'free_shipping' === $rate->method_id ) {
            // set them on a separated array
            $free[$rate_key] = $rate;

            // Remove "Free shipping" method from $rates array
            unset($rates[$rate_key]);
        } 
        // For other shipping rates with zero cost
        elseif ( $rate->cost == 0 ) {
            // set them on a separated array
            $zero[$rate_key] = $rate;

            // Remove the current method from $rates array
            unset($rates[$rate_key]);
        }
    }

    // Merge zero cost and "free shipping" methods at the end if they exist
    return ! empty( $free ) || ! empty( $zero ) ? array_merge($rates, $zero, $free) : $rates;
}

代码进入您的活动子主题（或活动主题）的 functions.php 文件。已测试并有效。

Refresh the shipping caches:
1). This code is already saved on your function.php file.
2). In a shipping zone settings, disable / save any shipping method, then enable back / save.
You are done and you can test it.

现在同样的事情**零成本和空成本先**：

add_filter( 'woocommerce_package_rates' , 'sort_shipping_method_by_cost_empty_zero_cost_first', 10, 2 );
function sort_shipping_method_by_cost_empty_zero_cost_first( $rates, $package ) {
    if ( empty( $rates ) || ! is_array( $rates ) ) return;

    // Sort shipping methods based on cost
    uasort( $rates, function ( $a, $b ) {
        if ( $a == $b ) return 0;
        return ( $a->cost < $b->cost ) ? -1 : 1;
    } );

    $free = $zero = []; // Initializing

    // Loop through shipping rates
    foreach ( $rates as $rate_key => $rate ) {
        // For "free shipping" methods
        if ( 'free_shipping' === $rate->method_id ) {
            // set them on a separated array
            $free[$rate_key] = $rate;

            // Remove "Free shipping" method from $rates array
            unset($rates[$rate_key]);
        } 
        // For other shipping rates with zero cost
        elseif ( $rate->cost == 0 ) {
            // set them on a separated array
            $zero[$rate_key] = $rate;

            // Remove the current method from $rates array
            unset($rates[$rate_key]);
        }
    }

    // Merge zero cost and "free shipping" methods at the end if they exist
    return ! empty( $free ) || ! empty( $zero ) ? array_merge($free, $zero, $rates) : $rates;
}
