我正在创建一个wordpress插件，并试图创建一个上传函数。然而，我得到了这些错误：
Warning: move_uploaded_file(logos/5041796eeedf21346468206.jpg) [function.move-uploaded-file]: failed to open stream: No such file or directory in /Applications/XAMPP/xamppfiles/htdocs/wordpress/wp-content/plugins/logo-updating/logo_menu.php on line 15
Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move '/Applications/XAMPP/xamppfiles/temp/phpeIJRwj' to 'logos/5041796eeedf21346468206.jpg' in /Applications/XAMPP/xamppfiles/htdocs/wordpress/wp-content/plugins/logo-updating/logo_menu.php on line 15
我的上传代码：
$tmp = $_FILES['logoUpload']['tmp_name'];
$extension = explode(".", $_FILES['logoUpload']['name']);
$everything = count($extension);
$ext = $extension[$everything - 1];
$newName = uniqid().time().".".$ext;
$newName2 = uniqid().time()."_banner.".$ext;
move_uploaded_file($tmp, "logos/".$newName);
$fullLink = "logos/".$newName;
$path_array = wp_upload_dir();
$path = str_replace('''', '/', $path_array['path']);
$target_path_sia = uniqid().$_FILES["file"]["name"];
move_uploaded_file($_FILES["file"]["tmp_name"],$path. "/" . $target_path_sia);
echo "Stored in: " . $path. "/" .$target_path_sia;
