在 woocommerce 中获取产品的下载 ID

Question

我在 wordpress 中使用 woocommerce。我为每个产品设置了 2 个要下载的文件，但是当我尝试使用以下代码调用两个下载文件链接时：

$download1=$product->get_files();

我得到以下数组：

[downloadable_files] => Array
        (
            [d289633f5c2d8f2f7cc9a102aea7242c] => Array
                (
                    [name] => Three Phase UPS1
                    [file] => http://localhost/creative/wp-content/uploads/woocommerce_uploads/2014/11/SolaPalm_DS.pdf
                )

            [413ff459269b8ed9e7c441eac585c035] => Array
                (
                    [name] => Three Phase UP2
                    [file] => http://localhost/creative/wp-content/uploads/woocommerce_uploads/2014/11/CFL_DS.pdf
                )

        )

虽然我想获取单个文件的下载 ID
这样我就可以使用 for 循环来获取所有下载产品的链接。

Answer 1

Woocommerce 方法是 get_downloads() ：

$product = wc_get_product($product_id);
     $downloads = $product->get_downloads();
     foreach ( $downloads as $key => $download ) {
         echo $key // gives - d289633f5c2d8f2f7cc9a102aea7242c
         echo $download["name"] // gives - Three Phase UPS1
         echo $download["file"] // gives - http://localhost/cre...
    }

Answer 2

$downloads = $product -> get_fields();
foreach ( $downloads as $key => $download ) {
   $key // gives - d289633f5c2d8f2f7cc9a102aea7242c
   $download["name"] // gives - Three Phase UPS1
   $download["file"] // gives - http://localhost/cre...
}

这应该可以满足您的需求
