-我在经营一家woo Commenters商店

-用户可以使用wp insert post添加产品

-product gallery multiple image upload（产品库多幅图像上载）只会将最后一幅图像添加到帖子中，但在媒体中，它们都会附加到正确的帖子中

这是我的密码

作用php

function my_handle_attachment($file_handler,$post_id,$set_thu=false) {
  if ($_FILES[$file_handler][\'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\');

  $attach_id = media_handle_upload( $file_handler, $post_id );

  if ( is_numeric( $attach_id ) ) {

    update_post_meta( $post_id, \'_product_image_gallery\', $attach_id );

  }
  return $attach_id;  
}

前端

if ( $_FILES ) { 
        $files = $_FILES["my_file_upload"];  

        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 ("my_file_upload" => $file); 

                    $newupload = my_handle_attachment( "my_file_upload", $post_id);


                } 

            } 

    }

输入

<input type="file" name="my_file_upload[]" multiple="multiple" >

这将上载所有图像并将其附加到正确的帖子，但只有最后一幅图像会显示在产品库图像部分。我做错了什么？
