您好我创建了一个上传功能,但有一个问题add_post_meta创建多个meta_key而不是一个...

示例: -

meta_key meta_value

_product_image_gallery 1
_product_image_gallery 2
_product_image_gallery 3 

应该是......

meta_key meta_value

_product_image_gallery 1,2,3


if ( $_FILES )

{

    $files = $_FILES['agp_gallery'];

    foreach ($files['name'] as $key => $value)

    {

        if ($files['name'][$key])

        {

            $file = array(

            'name' => $files['name'][$key],

            'type' => $files['type'][$key],

            'tmp_name' => $files['tmp_name'][$key],

            'error' => $files['error'][$key],

            'size' => $files['size'][$key]

            );

        }

        $_FILES = array("agp_gallery" => $file);

        $i=1;

        foreach ($_FILES as $file => $array)

        {

            $newupload = agp_process_wooimage($file,$post_id,$i);

            $i++;

        }

    }

}

function agp_process_wooimage($file, $post_id, $count)

{

    if ($_FILES[$file]['error'] !== UPLOAD_ERR_OK) __return_false();

    require_once(ABSPATH . "wp-admin" . '/includes/image.php');

    require_once(ABSPATH . "wp-admin" . '/includes/file.php');

    require_once(ABSPATH . "wp-admin" . '/includes/media.php');

    $attachment_id = media_handle_upload($file, $post_id);

    $post_id = array ();

    $array = array_push($post_id, '_product_image_gallery', $attachment_id);

    update_post_meta($post_id, '_product_image_gallery', $attachment_id);
}

对于每个循环,您调用media_handle_upload()并将新的$文件传递给它。我认为这会为每个文件创建一个新的附件ID。

然后在update_post_meta()中使用,如果不存在某些内容,则此函数默认使用add_post_meta()。它不会,因为你还没有在帖子中添加特定的附件。

我会看到此脚本按预期工作,您的问题可能会丢失。您是否要求将多个图像添加到单个meta_value中?
