Hi all, i've got a script that i've part edited to accept only certain file types to be uploaded, eg; JPG, PNG, JPEG etc. the script is originally part of the "uploadify script", im new to php so im finding it hard to work out how i can add a function to rename files on the backend so i dont get duplicates or errors on upload, but keep original names for the frontend. if this all makes sense, thanks in advance - Cody

PHP

if (!empty($_FILES)) {
	$tempFile = $_FILES['Filedata']['tmp_name'];
	$targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
	$targetFile =  str_replace('//','/',$targetPath) . $_FILES['Filedata']['name'];
	
	
	$fileTypes = array('jpg','jpeg','gif','png'); // File extensions
	$fileParts = pathinfo($_FILES['Filedata']['name']);
	
	if (in_array($fileParts['extension'],$fileTypes)) {
		move_uploaded_file($tempFile,$targetFile);
		echo '1';
	} else {
		echo 'Invalid file type.';
	}
}
?>

consider prefixing the file name with a unique identifier,

for example 12223434_myphoto.jpg and then substring the filename for "_" and display in the front end ?

Hi cjason406
If you want to rename only filename, it's very easy.
you can change value of $targetFile variable to new values.
for example:

PHP

      $targetFile =  str_replace('//','/',$targetPath) . 'yourname'.'jpg';

or
you can rewrite move_uploaded_file syntax
        $path="../images/profile/";
        $tagetName=$username;
        $extention=$fileParts['extension']; // so you can enter ext eg jpg
        move_uploaded_file($tempFile,$paht.$tagetName.$extention);
