Duplicate files?

Is there a way to prevent uploadify from over writing a file with the same name in the same folder?

Assuming I have /home/myweb/docs/cashews.doc and I'm uploading a new file called cashews.doc is there a way to rename the newer file to cashews-1.doc before it over writes the file in /home/myweb/docs?

Hopefully there's an easy solution for this...

Thanks for any help.

My guess is that you would have to make a few adjustments to the uploadify.php file. I haven't been using the script for very long, but I would check if the file exists in the php file and if it does just amend the filename value in $targetFile.


if (file_exists($targetFile)) {
    // update to new version
    // ... code to add version and check if that new name exists ...
    $targetFile = str_replace('//','/',$targetPath) . $newfilename;
}

Thanks for the reply.

I'm a bit green when it comes to coding in javascript...

If I change the file name to a new name with something as you suggest

if (file_exists($targetFile)) {
    // update to new version
    // ... code to add version and check if that new name exists ...
    $targetFile = str_replace('//','/',$targetPath) . $newfilename;
}

assuming I use a numbering scheme as I pointed out and the new file name I've given the file exists, will it comeback to this routine to be renamed again? will I be able to maintain a count?

$newfilename= $newfilename+ 1;

Well I tried your suggestion without success... uploading the same file had no change?

if (file_exists($targetFile)) {
// update to new version
// ... code to add version and check if that new name exists ...
$newfilename = "newfilename.doc"
$targetFile = str_replace('//','/',$targetPath) . $newfilename;
}

I see how this makes sense since the move_uploaded_file() function is the script but nothing is happening???

Any other suggestions for how to accomplish this?

In case anyone is interested in how I was able to solve (some borrowed source) this here is my script for future reference.

<?php
// Uploadify v1.6.2
// Copyright (C) 2009 by Ronnie Garcia
// Co-developed by Travis Nickels
if (!empty($_FILES)) {
	$tempFile = $_FILES['Filedata']['tmp_name'];
	$targetPath = $_SERVER['DOCUMENT_ROOT'] . $_GET['folder'] . '/';
	
	$file = $_FILES['Filedata']['name'];
	$file = utf8_decode($file);
	$file = ereg_replace(\"[^a-zA-Z0-9_.-\[\]()]\", \"\", strtr($file, \"()áàâãäéèêëíìîïóòôõöúùûüçÁÀÂÃÄÉÈÊËÍÌÎÏÓÒÔÕÖÚÙÛÜÇ \", \"[]aaaaaeeeeiiiiooooouuuucAAAAAEEEEIIIIOOOOOUUUUC_\"));
	
	$aux_targetPath = str_replace('//','/',$targetPath);
	$targetFile = str_replace('//','/',$targetPath) . $file;
	
	$returnFile = $_FILES['Filedata']['name'];
	
	$fnamecnt= 1; //sets a count variable to increment filenames
	while(file_exists($targetFile)) {
		$targetFile = $aux_targetPath . $fnamecnt . \"-\" . $file;
	$fnamecnt = $fnamecnt + 1;	//increment count by 1
	}
	move_uploaded_file($tempFile,$targetFile);
}
echo \"1\";
?>
