Answer 1

First, ensure that PHP is configured to allow file uploads.
In your "php.ini" file, search for the file_uploads directive, and set it to On:
file_uploads = On
Error Messages Explained
PHP returns an appropriate error code along with the file array. The error code can be found in the error segment of the file array that is created during the file upload by PHP. In other words, the error might be found in $_FILES['userfile']['error'].

Answer 2

First use print_r($_FILES) to check if the values r posting.
Use for loop instead of accessing index,
if(isset($_POST['submit'])){
foreach ($_FILES as $row) {
$filetmp = $row['tmp_name']; //getting error here
$filename = $row["name"]; //getting error here
$filepath = "../uploads/" . $filename;
move_uploaded_file($filetmp, $filepath);
}
