In my code, .mp3 files fail to upload but image files are uploading. What am I doing

[ug7766]

I wrote this code for a file(audio) upload application, but whenever I add a music file to the file input it shows "Notice: Undefined variable: theFIle". However, when I upload image files instead it works perfectly:

Here's the code below:

    <?php
 
$db_name = "745";
$db_user = "root";
$db_host = "localhost";
$db_password = "";
 
 
 
$mysqli = new mysqli('localhost','root','','745');
echo "<br>Connected<br>";
 
if($mysqli->connect_error){
  die('Connection Error: ('. $mysqli->connect_errno .') '. $mysqli->connect_error);
}
 
 
 
 
 
 
  if(isset($_POST['upload'])){
 
  $artist = $_POST["artist"];
  $song = $_POST["song"];
  $theFile = ($_FILES["filename"]["name"]);
  $uploadDir = "myDir1/";
  $uploadDir = $uploadDir.basename($_FILES["filename"]["name"]);
 
 
 
 
 
 $sql = $mysqli->query("INSERT INTO music1 (id, artiste, song, file) VALUES (id, '$artist', '$song', '$uploadDir')");
    echo "<br> INSERTED ".$uploadDir;
 
 if (move_uploaded_file($_FILES["filename"]["tmp_name"],$uploadDir)){
      echo "<br>file ".$_FILES['filename']['name']." uploaded to ".$uploadDir."<br>";
    }else{echo $_FILES['filename']['name']." not uploaded <br>";}
 
  }else{echo "<br>Wrong file type: only images allowed<br>";}
 
 
 $dir = "myDir";
// I use this line below for testing: to check test.txt if name of the file is captured properly. [It always is...in all cases except .mp3. :( ]
file_put_contents($dir."/test.txt",$theFile);
 
    ?>

- you fail to give the 'exact' error message. this way a reader here can only guess what might be wrong.
- you fail to use the '[code]' tags

Did you read the user notes on this page: http://php.net/manual/en/function.mo...oaded-file.php ?
