</form>

Answer 1

Just as the error states, there is no property on a $_FILES array entry called "audio/mpeg" :

$_FILES['file']['audio/mpeg']

(It would be pretty weird to have a property with that name on most files.)

There is , however, a property called "type" :

$file_type=$_FILES['file']['type'];

There's also no property called "1000000" , but there is one called "size" .
