Hi! I've made a script to import images from a directory into Exponential. It works fine, but uses the original file name. I want to use the same method for naming files as in eZ, any tips on how to do that? Roy

Hi, the renaming is because of browserupload in php in the temporary tmp folder. You can make unixsafe filenames with:
$saferImageName = strtolower( $image );
$saferImageName = preg_replace( array( "/[^a-z0-9_\. ]/" ,
"/ /",
"/__+/" ),
array( "",
"_",
"_" ),
$saferImageName );
rename($uploadFtpDir."/".$image,$uploadFtpDir."/".$saferImageName);
$image is original image name
$saferimagename is the new name
$uploadFtpDir is the ftpdir for batchupload
or the total batchuploadclass as a hack in progress with errors:

Thanks ekke! I wasn't aware of that. Your import script is very similar to mine, but I wanted new, and as it turned out, not quite random, but unique file names. So I made a function to generate unique file names, but similar on each run: $newFileName = makeImageFileName($fileName, $contentObject);
function makeImageFileName($fileName="", $node=false)
{
if (!$fileName || !$node) return;
$extension = preg_replace('/.*\.([A-z]{2,4})$/', '\\1', $fileName);
$nodeID = $node->attribute('id');
$nodeClass =& eZContentClass::fetch($node->attribute('contentclass_id'));
$identName = $nodeClass->attribute('identifier');
$newFileName = $identName . $nodeID . '.' . strtolower($extension);
return $newFileName;
} Roy

Hi ekke, Thanks for the functions, nice. I used the same function saveImage as you did, but added a check that the source file exist. You should also check that the file copy was a success before unlinking :-) Roy
