Auto Renaming Files

maskme

Dear All

What I need to do is:
When I upload an image and if it exists, it should not replace it but rename it as for e.g.
image[2].jpg

So the original image would be called as image.jpg and so next time if somebody adds the same image, it renames it incrementally.

How do we do this? Please help.
Thanks
Yusuf

Extract from FckEditor:
sFilePath contains the complete target of the existing image e.g. ../images/this.jpg

$iCounter = 0 ;
if ( is_file( $sFilePath ) )
	{
		$iCounter++ ;
		$sFileName = RemoveExtension( $sOriginalFileName ) . '(' . $iCounter . ').' . $sExtension ;
	}

Thanks for the reply, but RemoveExtension is not a PHP function?
I managed to remove the extension but its not incrementing between the () it adds another ()

does anyone else have any othe soln.

So ... remove the () as well.

Below is the code if you see the If file exists condition, i need to auto increment the values within ().

 function onlyfilename($file) {
   if(($pos = strrpos($file, '.')) !== false) {
      return basename(substr($file, 0, $pos));
   }
   return basename($file);
}

function UploadFiles($ufile)
 {
	$file1_u = $ufile['tmp_name']; //Temporary Upload
	$file1_name = $ufile['name']; //Get File Name
	$file1_type = $ufile['type']; //Get File Type
	$file1_size = $ufile['size']; //Get File Size	
	$time = time();				 

	if ($file1_name != "")
	{
			if( $file1_size > 500000 ) $mesg = $mesg. "<li>Invalid image size, Allowed only 500KB.</li>";
				if( $file1_type == "image/gif" )
				 {
					$iCounter = 0 ;
					if (file_exists("pictures/".$file1_name)) 
					 {
						$iCounter++ ;
						$sFileName = onlyfilename($file1_name) . '(' . $iCounter . ').' . $sExtension ;
					 }
					else
					 {
						copy("$file1_u", "pictures/{$file1_name}");
						$smesg = "http://www.domainname.com/pictures/{$file1_name}";							
					}
				 }
				if (isset($mesg)) return array($mesg, $smesg);  
					else  return array($mesg, $smesg); 
				}
 }

Sorry, iff you stil should need it here is the remove extension function:

function RemoveExtension( $fileName )
{
	return substr( $fileName, 0, strrpos( $fileName, '.' ) ) ;
}

thanks iwanpattyn
but i would like to know how would i increment the values within the ()
The solution you've provided only adds extra ()
your help is appreciated, thanx

Eric_T

have you tried "(" instead of '(' ?

I don't know this funtion so well, as i said it is an extract from FckEditor.
Try this:

 
$iCounter = 0 ; 
$iCounter++ ; 
$sFileName = RemoveExtension( $sOriginalFileName ) . '(' . $iCounter . ').' . $sExtension ;

Problem with this is that your renamed files wil be

this(1).jpg
this(11).jpg
this(111).jpg

in stead of

this(1).jpg
this(2).jpg
this(3).jpg
