在WooCommerce中添加自定義字段作爲購物車物品元和訂購物品元

Question

這是一個關於如何添加購物車物品meta的插件&我的WooCommerce訂單的訂單物品元。最初我的代碼對於輸入類型=文本很好。它返回值和輸入值的標籤。

轉換爲type=checkbox時，代碼將返回label和value="on"。

我想只返回選中值的值名稱（忽略未選中的值）。

幫助包含更多複選框選項的重構將有助於減少書面代碼。

我的代碼：

<?php 
    global $woocommerce, $product, $post; 

     add_action('woocommerce_before_add_to_cart_button', 'add_fields_before_add_to_cart'); 

     function add_fields_before_add_to_cart() { 
      ?> 

      <div class="simple-selects"> 
       <div class="col-md-6"> 
        <h3>Main meals</h3> 
        <p><input type="checkbox" name="mm_chicken_cutlet_bento" id="mm_chicken_cutlet_bento"><?php _e("Chicken Cutlet Bento", "aoim"); ?></p> 
        <p><input type="checkbox" name="mm_roasted_pork_rib_bento" id="mm_roasted_pork_rib_bento"><?php _e("Roasted Pork Rib Bento", "aoim"); ?></p> 
       </div> 
      </div>   

      <?php 
     } 

     /** 
     * Add data to cart item 
     */ 
     add_filter('woocommerce_add_cart_item_data', 'add_cart_item_data', 25, 2); 
     function add_cart_item_data($cart_item_meta, $product_id) { 

      if (isset($_POST ['mm_chicken_cutlet_bento']) && isset($_POST ['mm_roasted_pork_rib_bento'])) { 
       $custom_data = array() ; 
       $custom_data [ 'mm_chicken_cutlet_bento' ] = isset($_POST ['mm_chicken_cutlet_bento']) ? sanitize_text_field ($_POST ['mm_chicken_cutlet_bento']) : "" ; 
       $custom_data [ 'mm_roasted_pork_rib_bento' ] = isset($_POST ['mm_roasted_pork_rib_bento']) ? sanitize_text_field ($_POST ['mm_roasted_pork_rib_bento']): "" ; 
       $cart_item_meta ['custom_data']  = $custom_data ; 
      } 

      return $cart_item_meta; 
     } 

     /** 
     * Display custom data on cart and checkout page. 
     */ 
     add_filter('woocommerce_get_item_data', 'get_item_data' , 25, 2); 
     function get_item_data ($other_data, $cart_item) { 
      if (isset($cart_item [ 'custom_data' ])) { 
       $custom_data = $cart_item [ 'custom_data' ]; 

       $other_data[] = array('name' => 'Chicken Cutlet Bento', 'display' => $custom_data['mm_chicken_cutlet_bento']); 
       $other_data[] = array('name' => 'Roasted Pork Rib Bento', 'display' => $custom_data['mm_roasted_pork_rib_bento']); 
      } 

      return $other_data; 
     } 

     /** 
     * Add order item meta. 
     */ 
     add_action('woocommerce_add_order_item_meta', 'add_order_item_meta' , 10, 2); 
     function add_order_item_meta ($item_id, $values) { 
      if (isset($values [ 'custom_data' ])) { 
       $custom_data = $values [ 'custom_data' ]; 
       wc_add_order_item_meta($item_id, 'Chicken Cutlet Bento', $custom_data['mm_chicken_cutlet_bento']); 
       wc_add_order_item_meta($item_id, 'Roasted Pork Rib Bento', $custom_data['mm_roasted_pork_rib_bento']); 
      } 
     } 

?>

更新（相關評論）：

• 限制的功能只有一個產品ID
• 添加所有複選框值作爲昏迷分離的字符串

爲了得到輕鬆您的複選框的標籤名稱爲值和「重構，以幫助包括更多的複選框的選擇將有助於減少編寫的代碼，」我添加了一個簡單的功能在這裏設置的鍵/你要顯示的每個複選框和工藝值對...

所以我重新審視所有的代碼：

// HERE set the array of pairs keys/values for your checkboxes 
function custom_checkboxes(){ 
    return array(
     'mm_chicken_cutlet_bento'  => __("Chicken Cutlet Bento", "aoim"), 
     'mm_roasted_pork_rib_bento'  => __("Roasted Pork Rib Bento", "aoim"), 
    ); 
} 

// Displaying the checkboxes 
add_action('woocommerce_before_add_to_cart_button', 'add_fields_before_add_to_cart'); 
function add_fields_before_add_to_cart() { 
    global $product; 
    if($product->get_id() != 2) return; // Only for product ID "2" 

    ?> 
    <div class="simple-selects"> 
     <div class="col-md-6"> 
      <h3><?php _e("Main meals", "aoim"); ?></h3> 
      <?php foreach(custom_checkboxes() as $key => $value): ?> 
       <p><input type="checkbox" name="<?php echo $key; ?>" id="<?php echo $key; ?>"><?php echo ' ' . $value; ?></p> 
      <?php endforeach; ?> 
     </div> 
    </div> 
    <?php 
} 


// Add data to cart item 
add_filter('woocommerce_add_cart_item_data', 'add_cart_item_data', 25, 2); 
function add_cart_item_data($cart_item_data, $product_id) { 
    if($product_id != 2) return $cart_item_data; // Only for product ID "2" 

    // Set the data for the cart item in cart object 
    $data = array() ; 

    foreach(custom_checkboxes() as $key => $value){ 
     if(isset($_POST[$key])) 
      $cart_item_data['custom_data'][$key] = $data[$key] = $value; 
    } 
    // Add the data to session and generate a unique ID 
    if(count($data > 0)){ 
     $cart_item_data['custom_data']['unique_key'] = md5(microtime().rand()); 
     WC()->session->set('custom_data', $data); 
    } 
    return $cart_item_data; 
} 


// Display custom data on cart and checkout page. 
add_filter('woocommerce_get_item_data', 'get_item_data' , 25, 2); 
function get_item_data ($cart_data, $cart_item) { 
    if($cart_item['product_id'] != 2) return $cart_data; // Only for product ID "2" 

    if(! empty($cart_item['custom_data'])){ 
     $values = array(); 
     foreach($cart_item['custom_data'] as $key => $value) 
      if($key != 'unique_key'){ 
       $values[] = $value; 
      } 
     $values = implode(', ', $values); 
     $cart_data[] = array(
      'name' => __("Option", "aoim"), 
      'display' => $values 
     ); 
    } 

    return $cart_data; 
} 

// Add order item meta. 
add_action('woocommerce_add_order_item_meta', 'add_order_item_meta' , 10, 3); 
function add_order_item_meta ($item_id, $cart_item, $cart_item_key) { 
    if (isset($cart_item[ 'custom_data' ])) { 
     $values = array(); 
     foreach($cart_item[ 'custom_data' ] as $key => $value) 
      if($key != 'unique_key'){ 
       $values[] = $value; 
      } 
     $values = implode(', ', $values); 
     wc_add_order_item_meta($item_id, __("Option", "aoim"), $values); 
    } 
} 

此代碼放在你的活躍兒童主題（或主題）的function.php文件或也在任何插件文件中。

經過測試和工作。

你會得到這樣的事情：

我已經加入 「選項」，如標籤，以避免值的重複...
