Help with Image Upload

[mat3000000]

It will add the 'FILES' folder if it isn't there, but just refreshes the page, displaying no errors, without adding anything to the folder???

 

As you can probably see I have three file slots for users, I want to fill the next available slot up, and if no slots, display error 2 ($e=2; - Delete a file to make space)

 

//^^GET VARIABLES SUCH AS USERNAME ETC.

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

if(is_dir("files/$username/FILES/")){}else{mkdir("files/$username/FILES/");}

   if (is_uploaded_file($_FILES['file']['tmp_name'])) {
   
   $name = $_FILES['file']['name'];

      if ($file != "application/pdf" || substr(strrchr($file, '.'), 1) != "pdf" || substr(strrchr($file, '.'), 1) != "jpg" || $file != "image/jpeg" || $file != "image/pjpeg") {
         $errors[] = 'File must be in PDF or JPEG format';
      } 
  else if($_FILES['file']['size'] > 256000){$errors[] = 'File must be under 250KB';}
  
 else {
	 $name1 = substr($name, 0, strrpos($name, '.')); 
	 $ext = strtolower(substr(strrchr($name, '.'), 1));
	 $name = $name1.'.'.$ext;


	 $res = mysql_query("SELECT username,file1,file2,file3 FROM `files` WHERE `username`='$username'");
		$row = mysql_fetch_array($res);
		$f1 = $row['file1'];
		$f2 = $row['file2'];
		$f3 = $row['file3'];

		if($f1==''){

					$result = move_uploaded_file($_FILES['file']['tmp_name'], "files/$username/FILES/$name");
					 if ($result == 1){ 
					 $time = time();
					 $t=1;
					 mysql_query("UPDATE files SET file1='$name', file1_val='0', file1_added='$time' WHERE username='$username'");
					 	}else $e=1;

		}else if(empty($f2)){

					$result = move_uploaded_file($_FILES['file']['tmp_name'], "files/$username/FILES/$name");
					 if ($result == 1){ 
					 $time = time();
					 $t=1;
					 mysql_query("UPDATE files SET file2='$name', file2_val='0', file2_added='$time' WHERE username='$username'");
						}else $e=1;
