WordPress WooCommerce - 使用 WC_Cart 类将可变产品添加到购物车 [英] WordPress WooCommerce - Add a variable product to cart using the WC_Cart class

问题描述

我正在尝试将可变产品添加到 WordPress 插件 WooCommerce 的购物车中.

I am trying to add a variable product to the cart of the WordPress plugin, WooCommerce.

到目前为止，我已经能够添加单个/简单的产品:

So far I have been able to add single/simple products with:

$woocommerce->cart->add_to_cart( [product_id], [quantity] );

但是，查看 WC_Class 中的函数签名:

However, looking in the WC_Class at the functions signature:

function add_to_cart( $product_id, $quantity = 1, $variation_id = '', $variation = '', $cart_item_data = array() ) {

我们可以清楚地看到该函数允许输入variation_id.

we can clearly see the function permits inputs of variation_id.

我已经尝试了以下行的空值和整数的每种组合:

I have tried every combination of nulls and integers along the lines of:

$woocommerce->cart->add_to_cart( 24, 1, 28, null, null ); 

等等都无济于事.

我也尝试过我自己的hacky方法，试图重新创建由WooCommerce自己的产品页面执行的发布事件，但没有成功.

Ive also tried my own hacky approach that tries to recreate the post events performed by WooCommerce's own product page, again with no luck.

<a id="buy_v" href="#">Buy Variable Product !</a>    
<script>    
   $('#buy_v').click(function(e) {
      e.preventDefault();
      addToCartV(24,26,'Red',1);
      return false;
   });    
   function addToCartV(p_id, v_id, c, q) {    
    $.ajax({
      type: 'POST',
      url: '/wp/?product=tee1&add-to-cart=variation&product_id='+p_id,
      data: { 'attribute_colour': c,
              'variation_id':  v_id,
              'quantity':  q,
              'product_id':  p_id},
      success: function(response, textStatus, jqXHR){
            // log a message to the console
            console.log("It worked!");
        }/*,
      dataType: 'JSON'*/
    });    
   }   
</script>

有人可以建议我可能出错的地方吗?谢谢.

Could anyone suggest where I might be going wrong? Thanks.

推荐答案

上面的两个例子实际上都运行良好，只是在 WooCommerce 自己的购物车中没有正确显示.

Both the above example actually work fine, they just don't display correctly in WooCommerce's own cart.

为了使它们正确显示，请为第四个参数传递一个数组，该参数似乎代表 WooCommerce 自己的购物车中的变化:

To make them display correctly, pass in an array for the forth parameter which seems to represent the variation in WooCommerce's own cart:

$arr = array();
$arr['Color'] = 'Green';
$woocommerce->cart->add_to_cart( 24, 1, 28, $arr, null );
