如何将变体库存状态添加到Woocommerce产品变体下拉列表中

  好的，首先你需要得到这样的产品变化：

  $variations = $product->get_available_variations();
  

  在内部选项循环中，您需要遍历变量并找到当前选项库存状态

  foreach ($variations as $variation) {
      if($variation['attributes'][$name] == $option) {
          $stock = $variation['is_in_stock'];
  
      }
  }
  

  在变体循环之外，您需要添加库存和缺货变化的措辞

  if( $stock == 1) {
      $stock_content = ' - In stock';
  } else {
      $stock_content = ' - Out of stock';
  }
  

  然后更改html以包含一个额外的变量（$ stock_content）

  $html .= '<option value="' . esc_attr( $option ) . '" ' . $selected . '>' . esc_html( $option  .  $stock_content ) . '</option>';
  

  所以一个完整的函数将如下所示：

  add_filter( 'woocommerce_dropdown_variation_attribute_options_html', 'show_stock_status_in_dropdown', 10, 2);
  function show_stock_status_in_dropdown( $html, $args ) {
      $options = $args['options']; 
      $product = $args['product']; 
      $attribute = $args['attribute']; 
      $name = $args['name'] ? $args['name'] : 'attribute_' . sanitize_title( $attribute ); 
      $id = $args['id'] ? $args['id'] : sanitize_title( $attribute ); 
      $class = $args['class']; 
      $show_option_none = $args['show_option_none'] ? true : false; 
      $show_option_none_text = $args['show_option_none'] ? $args['show_option_none'] : __( 'Choose an option', 'woocommerce' ); 
  
    // Get all product variations
      $variations = $product->get_available_variations();
  
      if ( empty( $options ) && ! empty( $product ) && ! empty( $attribute ) ) { 
          $attributes = $product->get_variation_attributes(); 
          $options = $attributes[ $attribute ]; 
      } 
  
      $html = '<select id="' . esc_attr( $id ) . '" class="' . esc_attr( $class ) . '" name="' . esc_attr( $name ) . '" data-attribute_name="attribute_' . esc_attr( sanitize_title( $attribute ) ) . '" data-show_option_none="' . ( $show_option_none ? 'yes' : 'no' ) . '">'; 
      $html .= '<option value="">' . esc_html( $show_option_none_text ) . '</option>'; 
  
      if ( ! empty( $options ) ) { 
          if ( $product && taxonomy_exists( $attribute ) ) { 
            // Get terms if this is a taxonomy - ordered. We need the names too. 
            $terms = wc_get_product_terms( $product->get_id(), $attribute, array( 'fields' => 'all' ) ); 
  
            foreach ( $terms as $term ) { 
                  if ( in_array( $term->slug, $options ) ) { 
                      $html .= '<option value="' . esc_attr( $term->slug ) . '" ' . selected( sanitize_title( $args['selected'] ), $term->slug, false ) . '>' . esc_html( apply_filters( 'woocommerce_variation_option_name', $term->name ) ) . '</option>'; 
                  } 
              }
          } else {
              foreach ( $options as $option ) {
                      foreach ($variations as $variation) {
                          if($variation['attributes'][$name] == $option) {
                              $stock = $variation['is_in_stock'];
                          }
                      }       
                  if( $stock == 1) {
                      $stock_content = ' - (In Stock)';
                  } else {
                      $stock_content = ' - (Out of Stock)';
                  }
                   // This handles < 2.4.0 bw compatibility where text attributes were not sanitized. 
                  $selected = sanitize_title( $args['selected'] ) === $args['selected'] ? selected( $args['selected'], sanitize_title( $option ), false ) : selected( $args['selected'], $option, false ); 
  
                  $html .= '<option value="' . esc_attr( $option ) . '" ' . $selected . '>' . esc_html( $option  .  $stock_content ) . '</option>'; 
  
              }
          } 
      } 
  
      $html .= '</select>'; 
  
      return $html;
  }

  Update July 2018 （更改了错误的变量名 . 已为 1 dropdown 的变量产品启用）

  无论如何，当只有一个下拉选择字段（因此变体的一个属性）时，这将真正起作用 . 使用多个属性（因此有多个下拉选择字段），根据变体库存状态属性术语组合，它会显示可能出错的内容 . 查看最后显示错误展示位置的屏幕截图...

  我已经尝试了Ali_k的代码，但是在我的测试服务器中它是 not working 用于某些变量产品 .

  所以我对Ali_k的代码进行了一些修改以使其在我的测试服务器中运行（使用上一个WooCommerce版本）：

  // Function that will check the stock status and display the corresponding additional text
  function get_stock_status_text( $product, $name, $term_slug ){
      foreach ( $product->get_available_variations() as $variation ){
          if($variation['attributes'][$name] == $term_slug )
              $stock = $variation['is_in_stock'];
      }
  
      return $stock == 1 ? ' - (In Stock)' : ' - (Out of Stock)';
  }
  
  // The hooked function that will add the stock status to the dropdown options elements.
  add_filter( 'woocommerce_dropdown_variation_attribute_options_html', 'show_stock_status_in_dropdown', 10, 2);
  function show_stock_status_in_dropdown( $html, $args ) {
      // Only if there is a unique variation attribute (one dropdown)
      if( sizeof($args['product']->get_variation_attributes()) == 1 ) :
  
      $options               = $args['options'];
      $product               = $args['product'];
      $attribute             = $args['attribute']; // The product attribute taxonomy
      $name                  = $args['name'] ? $args['name'] : 'attribute_' . sanitize_title( $attribute );
      $id                    = $args['id'] ? $args['id'] : sanitize_title( $attribute );
      $class                 = $args['class'];
      $show_option_none      = $args['show_option_none'] ? true : false;
      $show_option_none_text = $args['show_option_none'] ? $args['show_option_none'] : __( 'Choose an option', 'woocommerce' );
  
      if ( empty( $options ) && ! empty( $product ) && ! empty( $attribute ) ) {
          $attributes = $product->get_variation_attributes();
          $options    = $attributes[ $attribute ];
      }
  
      $html = '<select id="' . esc_attr( $id ) . '" class="' . esc_attr( $class ) . '" name="' . esc_attr( $name ) . '" data-attribute_name="attribute_' . esc_attr( sanitize_title( $attribute ) ) . '" data-show_option_none="' . ( $show_option_none ? 'yes' : 'no' ) . '">';
      $html .= '<option value="">' . esc_html( $show_option_none_text ) . '</option>';
  
      if ( ! empty( $options ) ) {
          if ( $product && taxonomy_exists( $attribute ) ) {
              $terms = wc_get_product_terms( $product->get_id(), $attribute, array( 'fields' => 'all' ) );
  
              foreach ( $terms as $term ) {
                  if ( in_array( $term->slug, $options ) ) {
                      // HERE Added the function to get the text status
                      $stock_status = get_stock_status_text( $product, $name, $term->slug );
                      $html .= '<option value="' . esc_attr( $term->slug ) . '" ' . selected( sanitize_title( $args['selected'] ), $term->slug, false ) . '>' . esc_html( apply_filters( 'woocommerce_variation_option_name', $term->name ) . $stock_status ) . '</option>';
                  }
              }
          } else {
              foreach ( $options as $option ) {
                  $selected = sanitize_title( $args['selected'] ) === $args['selected'] ? selected( $args['selected'], sanitize_title( $option ), false ) : selected( $args['selected'], $option, false );
                  // HERE Added the function to get the text status
                  $stock_status = get_the_stock_status( $product, $name, $option );
                  $html .= '<option value="' . esc_attr( $option ) . '" ' . $selected . '>' . esc_html( apply_filters( 'woocommerce_variation_option_name', $option ) . $stock_status ) . '</option>';
              }
          }
      }
      $html .= '</select>';
  
      endif;
  
      return $html;
  }
  

  代码放在活动子主题（或主题）的function.php文件中，或者放在任何插件文件中 .

  经过测试并在变量产品中工作 that have only one attribute for variations ...

  使用Ali_K的代码，这里是变量产品 with multiple select fields 的错误显示文本的示例（因此变体的多个属性）：
