I have the following simple form, when I upload it goes back to upload.html, which is fine, but nothing is uploaded to the “uploads/” folder. No errors if it is the wrong file type and no results if it is the correct file type
<form name="uploadForm" method="post" action="upload.php" enctype="multipart/form-data">
Select an mp3 file only: <br>
<input name="user_file" type="file" /><br>
<input type="submit" name="upload" value="Upload">
</form>
and the following PHP
[php]<?php
