How to upload mp3 files - php

Question

Im trying to get a form to upload mp3 or certain image files to a folder.
Using below code I can upload the image files ok, but when i try to upload an mp3 i get the error Undefined index: file in C:\wamp\www\recordlabel\inc\soundclips.php on line 6 and the code echos invalid file from my else block. can anyone offer assistance?
$allowedExts = array("mp3", "jpeg", "jpg", "png");
$temp = explode(".", $_FILES["file"]["name"]);
$extension = end($temp);
if ((($_FILES["file"]["type"] == "audio/mp3")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/jpg")
|| ($_FILES["file"]["type"] == "image/pjpeg")
|| ($_FILES["file"]["type"] == "image/x-png")
|| ($_FILES["file"]["type"] == "image/png"))
&& in_array($extension, $allowedExts))
{
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br>";
echo "Type: " . $_FILES["file"]["type"] . "<br>";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>";
if (file_exists("../soundclips/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"../soundclips/" . $_FILES["file"]["name"]);
echo "Stored in: " . "../soundclips/" . $_FILES["file"]["name"];
}
}
}
else
{
echo "Invalid file";
}
And this is my form
<form class='form1' action='../inc/soundclips.php' method='post'
enctype='multipart/form-data'>
<input type="hidden" name="id" value="<?php echo $pid; ?>"/>
<b>Add Soundclip For <i><?php echo $e;?></i> </b>
<?php echo"<divclass='editimage'>";
echo "<img class='resizedimage' src='{$row['image']}' />";
echo"</div>";?><br />
<b>Song</b><br /><input type=text size='60' name='asong' /><br />
<input name='file' type="file" id="file" /><br />
<input type='submit' name='add' value='Add Soundclip' />
</form>

Looks like your mp3 file cannot be uploaded, so it is missing in $_FILES array. That might be due to its size compared to image files.
Please check upload_max_filesize and post_max_size settings from your php.ini and allow a greater size than your mp3 file.
