問題描述

我想在產品的股票選項下拉列表中添加一個新選項.默認情況下，有缺貨"，有貨"，我想添加第三個選項.

I would like to add a new option to the dropdown list of stocks options for a product. By default, there is "Out of stock", "In stock" and I would like to add a third option.

我找到了顯示下拉菜單的方法(在 class-wc-meta-box-product-data.php 中)

I found the method that displays the dropdown ( in class-wc-meta-box-product-data.php )

    // Stock status
    woocommerce_wp_select( array( 'id' => '_stock_status', 'wrapper_class' => 'hide_if_variable', 'label' => __( 'Stock status', 'woocommerce' ), 'options' => array(
        'instock' => __( 'In stock', 'woocommerce' ),
        'outofstock' => __( 'Out of stock', 'woocommerce' )
    ), 'desc_tip' => true, 'description' => __( 'Controls whether or not the product is listed as "in stock" or "out of stock" on the frontend.', 'woocommerce' ) ) );

    do_action( 'woocommerce_product_options_stock_status' );

但我不想直接編輯 Woocommerce 類，這樣我們就可以在不丟失任何自定義代碼的情況下更新 Woocommerce.有沒有辦法覆蓋這個方法?

But I don't want to edit Woocommerce class directly, so that we can update Woocommerce without losing any custom code. Is there a way to override this method ?

推薦答案

對于任何感興趣的人，這里是完整的解決方案，基于 Laila 的方法.警告！我的解決方案僅適用于 WooCommerce 禁用管理庫存"選項！我沒有處理確切數量的庫存物品.像往常一樣，所有代碼都轉到 functions.php.

for anyone interested, here is complete solution, based on Laila's approach. Warning! My solution is intended to work only with WooCommerce "manage stock" option disabled! I am not working with exact amounts of items in stock. All code goes to functions.php, as usual.

刪除本地庫存狀態下拉字段.添加 CSS 類以區分我的新自定義字段.下拉菜單現在有新選項應要求".

Removing native stock status dropdown field. Adding CSS class to distinguish my new custom field. Dropdown has now new option "On Request".

function add_custom_stock_type() {
    ?>
    <script type="text/javascript">
    jQuery(function(){
        jQuery('._stock_status_field').not('.custom-stock-status').remove();
    });
    </script>
    <?php   

    woocommerce_wp_select( array( 'id' => '_stock_status', 'wrapper_class' => 'hide_if_variable custom-stock-status', 'label' => __( 'Stock status', 'woocommerce' ), 'options' => array(
        'instock' => __( 'In stock', 'woocommerce' ),
        'outofstock' => __( 'Out of stock', 'woocommerce' ),
        'onrequest' => __( 'On Request', 'woocommerce' ), // The new option !!!
    ), 'desc_tip' => true, 'description' => __( 'Controls whether or not the product is listed as "in stock" or "out of stock" on the frontend.', 'woocommerce' ) ) );
}
add_action('woocommerce_product_options_stock_status', 'add_custom_stock_type');

遺憾的是，WooCommerce 將僅通過其原生功能保存有貨"或缺貨"值.所以在所有產品數據處理之后，我必須再次重新保存我的庫存狀態.

Sadly, WooCommerce will save only "instock" or "outofstock" values with its native functions. So after all product data processing, I have to re-save my stock status again.

function save_custom_stock_status( $product_id ) {
    update_post_meta( $product_id, '_stock_status', wc_clean( $_POST['_stock_status'] ) );
}
add_action('woocommerce_process_product_meta', 'save_custom_stock_status',99,1);

模板部分

最后一件事 - 我必須更改產品 get_availability() 函數返回的數據.當管理庫存"關閉時，WooCommerce 再次只知道instock"和outofstock"值.所以我自己檢查庫存狀態.

Template part

And the last thing - I have to alter data returned by product get_availability() function. When "managing stock" is off, WooCommerce only knows "instock" and "outofstock" values, again. So I have check stock status on my own.

function woocommerce_get_custom_availability( $data, $product ) {
    switch( $product->stock_status ) {
        case 'instock':
            $data = array( 'availability' => __( 'In stock', 'woocommerce' ), 'class' => 'in-stock' );
        break;
        case 'outofstock':
            $data = array( 'availability' => __( 'Out of stock', 'woocommerce' ), 'class' => 'out-of-stock' );
        break;
        case 'onrequest':
            $data = array( 'availability' => __( 'On request', 'woocommerce' ), 'class' => 'on-request' );
        break;
    }
    return $data;
}
add_action('woocommerce_get_availability', 'woocommerce_get_custom_availability', 10, 2);

也許它不是萬無一失的解決方案......我最終會更新它.

Maybe it's not bulletproof solution ... I will update it, eventually.
