[RESOLVED] validation on uploaded file input

[jrough]

There is a form with 3 inputs, 2 text fields and a uploaded file. When the form is submitted the action is this uploader.php script. My question, is there a way to validate the upload in the first if on the uploaded file so I only need one if/else block?

Also how do I attach the time to the file name? NOw it is attaching to the "csv.txt"
.txt extension. This is an internal form for doing a conversion so I'm not worried about security as user input and errors getting the file uploaded.
thanks,

ini_set("display_errors",1);
ini_set("memory_limit",'640M');
ini_set("max_execution",120);
ini_set("file_uploads",1);

$time=time();
$target_path = "file_uploads/";
// Add the original filename to our target path.
//Result is "uploads/filename.extension" */
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
 if  (filter_has_var(INPUT_POST, 'cart_id')&& filter_has_var(INPUT_POST, 'bu')){
  	$cart_id = $_POST["cart_id"];
        $bu = $_POST["bu"];
        echo $cart_id;
        echo $bu;

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path.$time)) {
   	    echo "The file ".  basename( $_FILES['uploadedfile']['name']).
            " has been uploaded";



} else{
	    echo "There was an error uploading the file,
             please try again.  The file must be a csv file.";
    }

 }else{
 echo "You are missing the cart_id or bu.";
   }

do i have to use filter_has_var with javascript on the form itself?

For your first question: not really - you have three possible outcomes and a single if/else statement only provides for two.
You could write it as

if(!filter_has_var....)
{
// Missing cart_id or bu
}
elseif(!move_uploaded_file...)
{
// Upload error
}
else
{
// everybody's happy.
}

For your second question you can use [man]basename[/man] (or [man]pathinfo[/man]) to get the filename without the extension (and the extension, too); once you've got them separated you can put them back together again with your timestamp in between.

For your third question, obviously you'd have to write a JavaScript version of filter_has_var() because you can't use the PHP function, but I'd recommend doing so as well as doing it on the server. It makes things faster for the user and eases some of the traffic on your server.
