我目前正在使用Dropzone。js，我可以创建dropzone，但是当我传入plugins\\u url作为操作时，我希望获得文件并使用wordpress文档中常见的insert\\u附件功能将其添加到wordpress媒体。

Dropzone：

<form id="udev-dropzone" method = "post" action="<?php echo plugins_url(\'/unrealdevs-portfolio/library/components/PortfolioUploader.php\'); ?>" class="dropzone" enctype="multipart/form-data">
    <input type="hidden" name="submitted" id="submitted" value="1" />
</form>

我在PortfolioUploader中的声明。php检查文件（我知道我需要添加nonce）：

if ( $_FILES ) {
$files = $_FILES;
$user = $_POST[\'user_id\'];
foreach ($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("upload_attachment" => $file);
            update_udevdb($user, $file); //Dismiss this line.
            foreach ($_FILES as $file => $array) {
                $newupload = insert_attachment($file);
                var_dump($file);
            }
        }
    }
}

insert\\u附件功能：

function insert_attachment($file_handler) {

  // check to make sure its a successful upload
  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, 0 );
}

有人能帮我吗？：）

EDIT: Here is the code that was used to correctly insert_attachment

function udev_before_uploader() { 
if ( !empty($_FILES) ) {
    $files = $_FILES;
    foreach($files as $file) {
        $newfile = array (
            \'name\' => $file[\'name\'],
            \'type\' => $file[\'type\'],
            \'tmp_name\' => $file[\'tmp_name\'],
            \'error\' => $file[\'error\'],
            \'size\' => $file[\'size\']
        );

        $_FILES = array(\'upload\'=>$newfile);
        foreach($_FILES as $file => $array) {
            $newupload = insert_attachment($file);
        }
    }
}



}

<form action="<?php echo admin_url( \'admin-post.php\' ); ?>" method="post">
  <input type="hidden" name="action" value="add_foobar">
  <input type="hidden" name="data" value="somedata">
  <input type="submit" value="Submit">
</form>

add_action( \'admin_post_add_foobar\', \'prefix_admin_add_foobar\' );
//this next action version allows users not logged in to submit requests
add_action( \'admin_post_nopriv_add_foobar\', \'prefix_admin_add_foobar\' );

function prefix_admin_add_foobar() {
    status_header(200);
    // load your processing.php file
    die();
}
