WooCommerce:根据个别商品数量添加折扣

标签: php wordpress woocommerce cart discount

在我的WooCommerce网站上,我有一些产品的价格相同 80 $
我想按产品数量添加折扣。

逻辑是这样的:

if (Products Quantity is 2){
   // the original product price change from 80$ to 75$ each.
}

if(Products Quantity is 3 or more){
   //the original product price change from 80$ to 70$ each.      
}

例如,

  

如果客户选择2个产品,则原始价格为 (80$ x 2) =>的 160$ 即可。   
但在折扣之后,它将是: (75$ x 2) =>的 150$

和...

  

如果访问者选择3个产品,原始价格将为 (80$ x 3) =>的 240$ 即可。   
但收费后,它将是: (70$ x 3) =>的 210$

请帮忙吗?

此自定义钩子函数应该按照您的预期执行。您可以根据单个商品数量设置累积折扣限制

这是代码

## Tested and works on WooCommerce 2.6.x and 3.0+
add_action( 'woocommerce_cart_calculate_fees', 'progressive_discount_by_item_quantity', 10, 1 );
function progressive_discount_by_item_quantity( $cart_obj ) {

    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    # Progressive quantity until quantity 3 is reached (here)
    # After this quantity limit, the discount by item is fixed
    # No discount is applied when item quantity is equal to 1

    // Set HERE the progressive limit quantity discount
    $progressive_limit_qty = 3; //  <==  <==  <==  <==  <==  <==  <==  <==   <==  <==  <==

    $discount = 0;

    foreach( $cart_obj->get_cart() as $cart_item_key => $item_values ){

        $qty = $item_values['quantity'];

        if( $qty =< $progressive_limit_qty )
            $param = $qty; // Progressive
        else
            $param = $progressive_limit_qty; // Fixed

        ## Calculation ##
        $discount -=  5 * $qty * ($param - 1); 
    }

    if( $discount < 0 )
        $cart_obj->add_fee( __( 'Quantity discount' ), $discount); // Discount

}

代码放在活动子主题(或主题)的function.php文件中,或者放在任何插件文件中。

测试并使用WooCommerce 2.6.x和3.0 +
