[SOLVED] upload script overwriting same name files

[Stooney]

I'm having a problem where when uploading a file with the same name as one already uploaded this script won't append numbers properly.

 

Say I want to upload bike.jpg but it already exists.  Well the script will rename it to 1-bike.jpg.  That works, but if 1-bike.jpg already exists it will overwrite it instead of incrementing to 2-bike.jpg.  It will always stop at 1 and continue to uploading.  Any ideas?

 

<?php
if(isset($_FILES['userfile']) && $_POST['dname']!="!e" && $_POST['dname']!="!r"){
	$uploaddir = "../dtf_files/";
	$_FILES['userfile']['name']=ereg_replace(" ", "_", $_FILES['userfile']['name']);
	$uploadfile = $uploaddir.basename($_FILES['userfile']['name']);
	$filename=$_FILES['userfile']['name'];
	if(file_exists($uploadfile)){
		$tmpVar=1;
		while(file_exists(basename($uploaddir.$tempVar.'-'.$_FILES['userfile']['name']))){
			$tmpVar++;
		}
		$filename=$tmpVar.'-'.$_FILES['userfile']['name'];
		$uploadfile=$uploaddir.$tmpVar.'-'.$_FILES['userfile']['name'];
	}

	if(move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)){
		$size=$_FILES['userfile']['size'];
		$type=$_FILES['userfile']['type'];
		$dname=mysql_real_escape_string($_POST['dname']);
		$category=mysql_real_escape_string($_POST['category']);
		$store=mysql_query("INSERT INTO dtf_files (dname, fname, path, size, dateadded, type, categoryid) VALUES ('$dname', '$filename', '$uploaddir', '$size', NOW(), '$type', '$category')");
		if(mysql_affected_rows()==1){
			$_POST['dname']="!r";
			upload_file();
		}
		else{
			$uerror="<p>SERVER ERROR:  Failed inserting data into database!</p>";
			$_POST['dname']="!e";
			upload_file();
		}
	}
	else{
		echo "<p>SERVER ERROR:  Failed uploading file!</p>";
	}
}
?>
