如何为“woocommerce_add_to_cart”添加过滤器或挂钩 [英] How to add filter or hook for "woocommerce_add_to_cart"

问题描述

我想添加到购物车的两个产品，一个是原来的（当前）产品，第二个是从下拉列表中。 （'woocommerce_add_to_cart'，'custome_add_to_cart'）;
$ cnt = 2
函数custome_add_to_cart（）{
global $ woocommerce;
$ cnt = $ cnt + 1;
echo $ cnt。X;
echo $ p_id = $ _ POST ['assessories'];
$ woocommerce-> cart-> add_to_cart（$ p_id，1）;




$输出：
正如你所看到的在下方输出图像，它在购物车中多次添加相同的下拉项目，但我只想要1个数量添加到购物车。似乎add_to_cart函数运行了很多次。
我应该怎么做，或者如何添加过滤器与传递第二下拉产品作为参数添加到购物车功能？所以我可以添加此产品也在购物车。

解决方案

woocommerceadd_to_cart函数运行钩子woocommerce_add_to_cart。所以，在你的代码中运行add_to_cart，运行woocommerce_add_to_cart，运行你的代码，运行add_to_cart，等等...你创建了一个递归循环。

您需要找到另一种方法，或者停止在您自己的代码中调用 $ woocommerce-> cart-> add_to_cart（$ p_id，1）; 。

I want add to cart two product at the same time, one is original (current) product and second is from drop-down list

add_action('woocommerce_add_to_cart', 'custome_add_to_cart');
$cnt=2
function custome_add_to_cart() {
    global $woocommerce;
      $cnt = $cnt + 1;
      echo $cnt."X";
      echo $p_id=$_POST['assessories'];
    $woocommerce->cart->add_to_cart($p_id, 1);

}

Output:- As you can see in output image below , it adding same drop-down item many time in cart but i want only 1 quantity to add to cart. it seems that add_to_cart function run many times. What should i do or how to add filter with passing second drop-down product as parameter to add to cart function ? so i can add this product also in cart.

解决方案

The woocommerce "add_to_cart" functions run the hook "woocommerce_add_to_cart". So, in your code "add_to_cart" is run, which is running "woocommerce_add_to_cart" which runs your code, which runs "add_to_cart", etcetera etcetera... You created a recursive loop.

You need to find an alternative way, or stop calling $woocommerce->cart->add_to_cart($p_id, 1); in your own code.
