删除 Woocommerce 中特定产品类别的添加购物车按钮

Question

我对如何从类别产品中删除购物车有疑问。如果我将它应用到特定的 id 或一般来说，它工作得很好，但我无法为一个类别做这件事。以下是我对此所做的代码。

另外，我正在努力将相同的模式应用于“相关文章”部分，因此我们将不胜感激。

谢谢。

//function for deleting ....

function remove_product_description_add_cart_button(){

    global $product;

    //Remove Add to Cart button from product description of product with id 1234    

    if ($product->id == 188){

    remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30 );

    }

add_action('wp','remove_product_description_add_cart_button');

}

要使其与产品类别一起使用，您可以通过这种方式使用 WordPress 条件函数 has_term()：

add_action('woocommerce_single_product_summary', 'remove_product_description_add_cart_button', 1 );
function remove_product_description_add_cart_button() { // function for deleting ...
    // Set HERE your category ID, slug or name (or an array)
    $categories = array('your-category-1');

    //Remove Add to Cart button from product description of product with id 1234
    if ( has_term( $categories, 'product_cat', get_the_id() ) ) {
        remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30 );
    }
}

代码进入您的活动子主题（或活动主题）的 function.php 文件中。或者也可以在任何插件 php 文件中。经过测试并且可以工作。

你可以试试这样的

function western_custom_buy_buttons(){

   $product = get_product();

   if ( has_term( 'category1', 'product_cat') ){

   // removing the purchase buttons

                            remove_action( 'woocommerce_after_shop_loop_item', 'woocommerce_template_loop_add_to_cart' );



   remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30 );

   remove_action( 'woocommerce_simple_add_to_cart', 'woocommerce_simple_add_to_cart', 30 );

   remove_action( 'woocommerce_grouped_add_to_cart', 'woocommerce_grouped_add_to_cart', 30 );

   remove_action( 'woocommerce_variable_add_to_cart', 'woocommerce_variable_add_to_cart', 30 );

   remove_action( 'woocommerce_external_add_to_cart', 'woocommerce_external_add_to_cart', 30 );

   }

}

add_action( 'wp', 'western_custom_buy_buttons' );

Answer 3

你已经尝试过这样的事情：

function remove_product_description_add_cart_button(){

global $product;

    $termsOfProduct =  wp_get_post_terms( $product->id, 'product_cat' );   

    if (in_array("CatToFind", $termsOfProduct)) {

    remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30 );

    }

add_action('wp','remove_product_description_add_cart_button');

}

Woocommerce 中的类别产品只是术语。 wp_get_post_terms 允许您查找与帖子（产品 ID）相关的任何类别。
