从结帐页面 woocommerce 更新购物车中的产品

Question

我正在尝试在使用 ajax 进行付款（来自订单审核表）之前从结帐页面更新购物车中的产品。

但我做不到。

1. 首先，我将使用自定义元功能“存储自定义字段”添加到购物车。

   add_filter('woocommerce_add_cart_item_data', 'save_custom_data_with_add_to_cart', 10, 2); 功能 save_custom_data_with_add_to_cart( $cart_item_meta, $product_id ) { 全球$woocommerce； $category_id = urldecode(base64_decode($_GET['c'])); $board_id = urldecode(base64_decode($_GET['b'])); $board_name = get_the_title($board_id); $cart_item_meta['slot_id'] = $category_id; $cart_item_meta['board_id'] = $board_id; $cart_item_meta['board_title'] = $board_name;
   返回 $cart_item_meta; }

2. 然后我想在结帐页面更改产品（订单评论选择）

   购物车->get_cart());

           foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
               $_product     = apply_filters( 'woocommerce_cart_item_product', $cart_item['data'], $cart_item, $cart_item_key );           
   
               if ( $_product && $_product->exists() && $cart_item['quantity'] > 0 && apply_filters( 'woocommerce_checkout_cart_item_visible', true, $cart_item, $cart_item_key ) ) {
                   ?>
                   <tr class="<?php echo esc_attr( apply_filters( 'woocommerce_cart_item_class', 'cart_item', $cart_item, $cart_item_key ) ); ?>">
   
                       <td class="product-name">   
                           <a href="#" class="edit_product"><i class="fa fa-pencil" aria-hidden="true"></i></a> &nbsp; <?php echo apply_filters( 'woocommerce_cart_item_name', $_product->get_name(), $cart_item, $cart_item_key ) . '&nbsp;'; ?>
                           <?php echo apply_filters( 'woocommerce_checkout_cart_item_quantity', ' <strong class="product-quantity">' . sprintf( '&times; %s', $cart_item['quantity'] ) . '</strong>', $cart_item, $cart_item_key ); ?>
                           <?php echo WC()->cart->get_item_data( $cart_item ); ?>  
                       <!--haredra code here -->
                       <select name="plan" id="plan" class="plan" >                        
                       <option >change product</option>
                       <option value="1">gold</option>
                       <option value="2">sliver</option>
                       <option value="3">bronze</option>
                       </select>
                       <input type="hidden" class="board_id" value="<?php echo $cart_item['board_id'] ;?>">
                       <input type="hidden" class="slot_id" value="<?php echo $cart_item['slot_id'] ;?>">
                       <input type="hidden" class="cart_item_key" value="<?php echo $cart_item['key'] ;?>"> 
                       </td>                       
   
                       <td class="product-total">
                           <?php echo apply_filters( 'woocommerce_cart_item_subtotal', WC()->cart->get_product_subtotal( $_product, $cart_item['quantity'] ), $cart_item, $cart_item_key ); ?>
   
                       </td>
   
                   </tr>
                   <?php
               }
           } 
       ?>
   

3. JQuery 帮助发送数据并获得响应..

   $('body').on('click', '.edit_product', function(e){ $('#plan').show(); }); /// js 用于订单审核更新产品 jQuery(文档).ready(函数($){ $('body').on('change', '#plan', function(e){ var product_id = $('.plan').val(); var board_id = $('.board_id').val(); var slot_id = $('.slot_id').val(); var cart_item_key = $('.cart_item_key').val(); var ajaxurlsb = "" $.ajax({ 类型：“发布”， url: ajaxurlsb+"?action=update_order_review", 数据：“product_id="+product_id+"&board_id="+board_id+"&slot_id="+slot_id+"&cart_item_key="+cart_item_key, 成功：函数（数据）{ 警报（数据）； } }); }); });

4. 更新功能

   //==============结帐订单审核更新===========// 功能更新订单审查（）{ $product_id = $_POST['product_id']; $board_id = $_POST['board_id']; $board_name = get_the_title($board_id); $slot_id = $_POST['slot_id']; $cart_item_key = $_POST['cart_item_key']; if ( !empty($product_id) && !empty($board_id ) ) { //这里我想更新产品ID } print_r($product_); 死（）; } add_action('wp_ajax_update_order_review', 'update_order_review'); add_action('wp_ajax_nopriv_update_order_review', 'update_order_review');

问。给出一个解决方案来改变products id和item custom meta data.in this function.??

Answer 1

更新功能代码

//+++==============chackout oder review upadte===========//

function update_order_review() {

      $_product = wc_get_product( $product_id );
      $price = $_product->get_price();
      $cart_item_key = $_POST['cart_item_key']; 
        /*===set value in cart====*/
        WC()->cart->cart_contents[$cart_item_key]['product_id'] = $product_id ;
        WC()->cart->cart_contents[$cart_item_key]['line_subtotal'] = $price ;
        WC()->cart->cart_contents[$cart_item_key]['line_total'] = $price ;
        $woocommerce->cart->set_session();

die();
}
add_action('wp_ajax_update_order_review', 'update_order_review');
add_action('wp_ajax_nopriv_update_order_review', 'update_order_review');
