Help scripting uploader for images and audio

[perpetualwombat]

Hello this is my first post on this forum. I am an amateur web programmer, self taught, and I'm making a non commercial website to support local musicians. Basically I am having a difficult time scripting a php form for artists to submit their info to me as well as upload an image and an audio file to my remote server for me to preview.
I've been working on this all day and just cant seem to figure it out.

The mailer form data I am grabbing fine and is working but I cannot get files to upload also I don't know how to define the file types allowed for separately in the form.

<?php
if(isset($_POST['submit'])) {

$my_email = "------";
$subject = "New Track";
$email_field = $_POST['email'];
$artist_field = $_POST['artist'];
$artisturl_field = $_POST['artisturl'];
$genre_field = $_POST['genre'];
$loc_field = $_POST['loc'];
$trackn_field = $_POST['trackn'];
$trackurl_field = $type[$_REQUEST['trackurl']];



$body = "Artist: $artist_field\nEmail: $email_field\nURL: $artisturl_field\nGenre: $genre_field\nLoc: $loc_field\nTrack Title: $trackn_field, $trackurl_field";

echo "Thank you for your submission.";

mail($my_email, $subject, $body);

} else {

echo "error data not sent please contact [e-mail]";

}
if ((($_FILES["file"]["type"] == "audio/mpeg")
|| ($_FILES["file"]["type"] == "audio/x-mpeg")
|| ($_FILES["file"]["type"] == "audio/mp3")
|| ($_FILES["file"]["type"] == "audio/x-mp3")
|| ($_FILES["file"]["type"] == "audio/mpeg3")
|| ($_FILES["file"]["type"] == "audio/x-mpeg3")
|| ($_FILES["file"]["type"] == "audio/mpg")
|| ($_FILES["file"]["type"] == "audio/x-mpg")
|| ($_FILES["file"]["type"] == "audio/x-mpegaudio")
|| ($_FILES["file"]["type"] == "audio/wav")
|| ($_FILES["file"]["type"] == "audio/x-wav")
|| ($_FILES["file"]["type"] == "audio/x-aiff")
|| ($_FILES["file"]["type"] == "audio/x-aac")
|| ($_FILES["file"]["type"] == "audio/mp4")
|| ($_FILES["file"]["type"] == "audio/m4a")
|| ($_FILES["file"]["type"] == "audio/m4p"))
&& ($_FILES["file"]["size"] < 500000))

{
  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("upload/" . $_FILES["file"]["name"]))
  {
  echo $_FILES["file"]["name"] . " already exists. ";
  }
else
  {
  move_uploaded_file($_FILES["file"]["tmp_name"],
  "upload/" . $_FILES["file"]["name"]);
  echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
  }
}
  }
else
  {
  echo "Invalid file";
}
?> 

That's what I have so far I was just trying to get the song to upload I have not even added the image part. Any help or direction I'd appreciate so much thank you.

do you have the enctype attribute in your form?

<form method="" action="" enctype="multipart/form-data">

I do have that enctype. I actually made some progress and everything is sending/uploading (although I have to change my php.ini or something so i can increase the upload max filesize) I am still running into a problem where when I submit it outputs the following "Sorry, there was a problem uploading your file.Sorry, there was a problem uploading your file.Thank you for your submission. "
Even if there are no problems.
Here is what my code looks like now --

if(isset($_POST['submit'])) {

$my_email = "[e-mail]";
$subject = "New Track";
$email_field = $_POST['email'];
$artist_field = $_POST['artist'];
$artisturl_field = $_POST['artisturl'];
$genre_field = $_POST['genre'];
$loc_field = $_POST['loc'];
$trackn_field = $_POST['trackn'];
$trackurl_field = $type[$_REQUEST['trackurl']];

// --File Uploads
$target = "upload/"; 
 $target = $target . basename( $_FILES['trackup']['name']) ; 
 $ok=1; 

 // size condition 
 if ($uploaded_size > 50000000) 
 { 
 echo "Your file is too large.<br>"; 
 $ok=0; 
 } 

 //check that $ok was not set to 0 by an error 
 if ($ok==0) 
 { 
 Echo "Sorry your file was not uploaded"; 
 } 

 //upload it 
 else 
 { 
 if(move_uploaded_file($_FILES['trackup']['tmp_name'], $target)) 
 { 
 echo "The file ". basename( $_FILES['trackupfile']['name']). " has been uploaded"; 
 } 
 else 
 { 
 echo "Sorry, there was a problem uploading your file."; 
 } 
 }
 $target = "upload/"; 
 $target = $target . basename( $_FILES['imgup']['name']) ; 
 $ok=1; 

 // size condition 
 if ($uploaded_size > 50000000) 
 { 
 echo "Your file is too large.<br>"; 
 $ok=0; 
 } 

 //check that $ok was not set to 0 by an error 
 if ($ok==0) 
 { 
 Echo "Sorry your file was not uploaded"; 
 } 

 //upload it 
 else 
 { 
 if(move_uploaded_file($_FILES['imgup']['tmp_name'], $target)) 
 { 
 echo "The file ". basename( $_FILES['imgupfile']['name']). " has been uploaded"; 
 } 
 else 
 { 
 echo "Sorry, there was a problem uploading your file."; 
 } 
 } 

$body = "Artist: $artist_field\nEmail: $email_field\nURL: $artisturl_field\nGenre: $genre_field\nLoc: $loc_field\nTrack Title: $trackn_field\nDownload: $trackurl_field";

echo "Thank you for your submission.";

mail($my_email, $subject, $body);

} else {

echo "error data not sent please contact [e-mail]";
}
