php fail to upload file

Question

I have a problem with uploading file with PHP. The html code is

<form enctype="multipart/form-data" id="form" action="action.php">
    <input type="file" name="file"/><br/><br/>
    <input type="submit" id="upload" value="Upload"/>
</form> 

and the PHP segment is

if($_FILES["file"]["error"]>0){
    $result['status'] = -1;
    $result['message'] = 'Unknown Error';
}
else{
    $file = $_FILES["file"];
    $savepath = '/CSV Files/'.$file["name"];
    move_uploaded_file($file['tmp_name'],$savepath);
}

The problem is the $result['status'] is not -1, but the $file is a null. And the strange thing is, the code worked well days ago, and suddenly died recently.Hope somebody could help me out. Thanks a lot!

You have missed to add method="POST" in your <form> tag

<form method="POST" enctype="multipart/form-data" id="form" action="design.php">
      ^^^^^^^^^^^^^
