Question

我正在尝试将各种图片从网址上传到给定的woocommerce产品。我对我的代码所面临的问题是，虽然我看到图像正在上传到服务器，但当我去看我的帖子时，我只看到上传到图库的最后一张图片。

这是我的代码：

function generateSecondImage($image_url, $post_id)
{
    $upload_dir = wp_upload_dir();
    $image_data = file_get_contents($image_url);
    $filename = basename($image_url);
    if (wp_mkdir_p($upload_dir['path'])) {
        $file = $upload_dir['path'] . '/' . $filename;
    } else {
        $file = $upload_dir['basedir'] . '/' . $filename;
    }

    file_put_contents($file, $image_data);

    $wp_filetype = wp_check_filetype($filename, null);
    $attachment = array(
        'post_mime_type' => $wp_filetype['type'],
        'post_title' => sanitize_file_name($filename),
        'post_content' => '',
        'post_status' => 'inherit',
    );
    $attach_id = wp_insert_attachment($attachment, $file, $post_id);
    require_once ABSPATH . 'wp-admin/includes/image.php';
    $attach_data = wp_generate_attachment_metadata($attach_id, $file);
    $res1 = wp_update_attachment_metadata($attach_id, $attach_data);
    $res3 = update_post_meta($post_id, '_product_image_gallery', $attach_id);

}

这就是我如何调用函数

 for ($j=1; $j <$picCount ; $j++) { 
 generateSecondImage($pic[$j]->url, $post_id);
 }

我想也许，res3正在覆盖图库并仅显示最后发布的图像，但如果是这种情况，我如何告诉wordpress将所有图像包含在for loop？

终于设法解决了！

这是我的最终代码。我的上传功能如下：

function generateSecondImage($image_url, $post_id)
{
    $upload_dir = wp_upload_dir();
    $image_data = file_get_contents($image_url);
    $filename = basename($image_url);
    if (wp_mkdir_p($upload_dir['path'])) {
        $file = $upload_dir['path'] . '/' . $filename;
    } else {
        $file = $upload_dir['basedir'] . '/' . $filename;
    }

    file_put_contents($file, $image_data);

    $wp_filetype = wp_check_filetype($filename, null);
    $attachment = array(
        'post_mime_type' => $wp_filetype['type'],
        'post_title' => sanitize_file_name($filename),
        'post_content' => '',
        'post_status' => 'inherit',
    );
    $attach_id = wp_insert_attachment($attachment, $file, $post_id);
    require_once ABSPATH . 'wp-admin/includes/image.php';
    $attach_data = wp_generate_attachment_metadata($attach_id, $file);
    $res1 = wp_update_attachment_metadata($attach_id, $attach_data);

    echo "Attach ID is".$attach_id;
    return $attach_id;

}

然后我必须创建以逗号分隔的ID列表并将其添加到add_post_meta

所以我的循环改为：

for ($j=1; $j <$picCount ; $j++) { 
$attarray[] = generateSecondImage($pic[$j]->url, $post_id);
}

$commaList = implode(', ', $attarray);
$res3 = add_post_meta($post_id, '_product_image_gallery', $commaList);

希望这可以帮助其他人寻找解决方案。
