WooCommerce 自定义产品类型 - 多个添加到购物车部分问题

Question

我在 woocommerce 中创建了一个名为 Booking 的自定义产品类型。

这是我的代码：

class WC_Product_Booking extends WC_Product{
    /**
     * __construct function.
     *
     * @access public
     * @param mixed $product
     */
    public function __construct( $product ) {
        $this->product_type = 'booking';
        $this->supports[]   = 'ajax_add_to_cart';
        parent::__construct( $product );
        add_action('woocommerce_booking_add_to_cart', array($this, 'add_to_cart'),30);
    }

    private function show_pricing_fields(){
      ?><script type='text/javascript'>
        jQuery( document ).ready( function() {
          jQuery( '.options_group.pricing' ).addClass( 'show_if_booking' ).show();
        });
      </script><?php
    }
    /**
     * Display the add to cart button (same as for simple product)
     */
    public function add_to_cart() {
      wc_get_template( 'single-product/add-to-cart/simple.php' );
    }
}

目前唯一的问题是产品页面上的添加到购物车部分显示了 6 次，我不明白为什么。

我该如何解决这个问题？

谢谢

@Update …解决方案 （因为LoicTheAztec让我走上正轨）:

我找到了解决这个问题的方法，使用这段代码

if (! function_exists( 'woocommerce_booking_add_to_cart' ) ) {

  /**
  * Output the simple product add to cart area.
  *
  * @subpackage Product
  */

  function booking_add_to_cart() {
    wc_get_template( 'single-product/add-to-cart/simple.php' );
  }

  add_action('woocommerce_booking_add_to_cart',  'booking_add_to_cart');
}

关键是这个动作add_action('woocommerce_booking_add_to_cart', 'booking_add_to_cart');

将添加到购物车按钮放在正确的位置 - 要在您自己的自定义产品中使用它，请执行名为 woocommerce_YOURPRODUCTTYPE_add_to_cart

的操作

Answer 1

已尝试在测试服务器上测试您的代码，但您的预订产品未在后端显示。

您的问题可能出自此处：我认为您使用的是 public function add_to_cart() 现有名称函数，您必须以不同方式重命名它。

然后我重新访问了您的代码，based on this thread。

扩展 WC_Product_Simple class 比 WC_Product class，因为您的产品使用简单的产品添加到购物车按钮模板：
single-product/add-to-cart/simple.php.

有了这个自定义代码，我就不会像你一样面对多次添加到购物车部分。

— @Update1 —
But you can still keep WC_Product extended instead of WC_Product_Simple. This way, as you requested in comment, your product type will be "simple_booking" as specified in 1st and 2nd functions. That does not mean that your product is simple (it's just a slug that you can change, changing at the same time in both places).

So I have modified the code again and tested: It works…

这是我使用的代码（我测试过）:

/**
 * Register the custom product type after init
 */
function register_simple_booking_product_type() {

    /**
     * This should be in its own separate file.
     */
    class WC_Product_Booking extends WC_Product{ // <= changed back to WC_product class

        public function __construct( $product ) {

            $this->product_type = 'simple_booking';
            $this->supports[]   = 'ajax_add_to_cart';

            parent::__construct( $product );

            // As we extend simple product class, you may not need this anymore.
            add_action('woocommerce_booking_add_to_cart', array($this, 'simple_booking_add_to_cart'),30);

        }

    }

}
add_action( 'init', 'register_simple_booking_product_type' );

// Registering the slug name (YOU can CHANGE IT)
function add_simple_booking_product( $types ){

    // Key should be exactly the same as in the class product_type parameter
    $types[ 'simple_booking' ] = __( 'Simple booking' );

    return $types;

}
add_filter( 'product_type_selector', 'add_simple_booking_product' );

/**
 * Show pricing fields for simple_booking product.
 */
function simple_booking_custom_js() {

    if ( 'product' != get_post_type() ) :
        return;
    endif;

    ?><script type='text/javascript'>
        jQuery( document ).ready( function() {
            jQuery( '.options_group.pricing' ).addClass( 'show_if_simple_booking' ).show();
        });
    </script><?php
}
add_action( 'admin_footer', 'simple_booking_custom_js' );

// Not sure you will need that (because of the change of the extended class)
function simple_booking_add_to_cart() {
    wc_get_template( 'single-product/add-to-cart/simple.php' );
}

在位于活动子主题 （或主题）.

中的 function.php 文件上测试了此代码

参考：Adding a custom WooCommerce product type

— @Update2 — The solution (find by the author of this question):

To puts the add-to-cart button once in the right place (to use it in your own custom product make an action called woocommerce_YOURPRODUCTTYPE_add_to_cart), with this code:

if (! function_exists( 'woocommerce_booking_add_to_cart' ) ) {

  /**
  * Output the simple product add to cart area.
  *
  * @subpackage Product
  */

  function booking_add_to_cart() {
    wc_get_template( 'single-product/add-to-cart/simple.php' );
  }

  add_action('woocommerce_booking_add_to_cart',  'booking_add_to_cart');
}
