问题描述

在woocommerce中，我正在使用隐藏从购物车中删除WooCommerce产品类别的答案代码，我也希望禁用购物车数量字段，以避免客户将商品数量更改为零。

In woocommerce I am using Hide "remove item" from cart for WooCommerce product category answer code and I would like to disable the cart quantity field too, avoiding customer to change the item quantity to zero.

推荐答案

以下代码将从特定商品中的购物车中删除数量字段产品类别（您将在第二个函数中定义）：

The following code will remove the "quantity field" from cart for items from a specific product category (that you will define in the 2nd function):

// Custom conditional function that checks for categories (including parent)
function has_product_categories( $product_id, $categories ) {
     // Initializing
    $parent_term_ids = $categories_ids = array();
    $taxonomy        = 'product_cat';

    // Convert categories term names and slugs to categories term ids
    foreach ( $categories as $category ){
        if( is_numeric( $category ) ) {
            $categories_ids[] = (int) $category;
        } elseif( term_exists( sanitize_title( $category ), $taxonomy ) ) {
            $categories_ids[] = get_term_by( 'slug', sanitize_title( $category ), $taxonomy )->term_id;
        }
    }

    // Loop through the current product category terms to get only parent main category term
    foreach( get_the_terms( $product_id, $taxonomy ) as $term ){
        if( $term->parent > 0 ){
            $parent_term_ids[] = $term->parent; // Set the parent product category
            $parent_term_ids[] = $term->term_id; // (and the child)
        } else {
            $parent_term_ids[] = $term->term_id; // It is the Main category term and we set it.
        }
    }
    return array_intersect( $categories_ids, array_unique($parent_term_ids) ) ? true : false;
}

add_filter( 'woocommerce_quantity_input_args', 'hide_cart_quantity_input_field', 20, 2 );
function hide_cart_quantity_input_field( $args, $product ) {
    // HERE your specific products categories
    $categories = array( 'clothing' );

    // Handling product variation
    $product_id = $product->is_type('variation') ? $product->get_parent_id() : $product->get_id();

    // Only on cart page for a specific product category
    if( is_cart() && has_product_categories( $product_id, $categories ) ){
        $input_value = $args['input_value'];
        $args['min_value'] = $args['max_value'] = $input_value;
    }
    return $args;
}

代码进入活动子主题（或活动主题）的function.php文件）。经过测试并且可以正常工作。

Code goes in function.php file of your active child theme (or active theme). Tested and works.

注意：如果您还使用其他答案代码，则第一个功能已经存在定义，而不必在函数php文件中重复两次……

Note: If you are using also your other answer code, the first function is already defined and doesn"t have to be twice on your function php file…
