renaming files on upload

Was wondering if it would be possible to add First_Name and Last_Name from form fields to the upload "Params" on an insert page. Attempting to identify each image with the person filling out the form. I don't know php code that well, but it appears this would be the place to do this. I tried some simple configurations which added that text to the name of image file (and placed in database table), but not data coming from the fields - even attempted "echo" command. But again I don't know the code that well.

Here is the code from the page for the first image upload with just the FileName being used:

<?php
// WA_UploadResult1 Params Start
$WA_UploadResult1_Params = array();
// WA_UploadResult1_1 Start
$WA_UploadResult1_Params["WA_UploadResult1_1"] = array(
'UploadFolder' => "artists_images",
'FileName' => "[FileName]",
'DefaultFileName' => "",
'ResizeType' => "0",
'ResizeWidth' => "0",
'ResizeHeight' => "0",
'ResizeFillColor' => "" );
// WA_UploadResult1_1 End
// WA_UploadResult1 Params End
?>

you don't really need to know the code for this, just use the dynamic bindings and some creative Copy and Paste .

In the File Upload behavior, click the lightning bolt icon next to the eFile Name setting and select the first name binding, that will populate the name setting field with the code for the first name similar to:
<?php echo((isset($_POST["First_Name"]))?$_POST["First_Name"]:"") ?>

now Copy that (CTRL+C for Windows Or CMD+C on MAC)

Click the lightning bolt icon again and select the Last Name form element binding, this will populate the file Name setting with the binding code for the last name form element similar to:
<?php echo((isset($_POST["Last_Name"]))?$_POST["Last_Name"]:"") ?>

place your cursor at the begging of the file name input and use the Paste command (CTRL+V on Windows or CMD+V On Mac) to paste the first name binding code in front of the last name binding code, the result will be similar to:
<?php echo((isset($_POST["First_Name"]))?$_POST["First_Name"]:"") ?><?php echo((isset($_POST["Last_Name"]))?$_POST["Last_Name"]:"") ?>


Now if you also want the name of the file to be added on to the end, place your cursor at the end pf the code and add [FileName], so the full code will now be similar to:
<?php echo((isset($_POST["First_Name"]))?$_POST["First_Name"]:"") ?><?php echo((isset($_POST["Last_Name"]))?$_POST["Last_Name"]:"") ?>[FileName]


when you click finish it will generate the php code for you and set the code for the file name as:

'FileName' => "".((isset($_POST["First_Name"]))?$_POST["First_Name"]:"") ."".((isset($_POST["Last_Name"]))?$_POST["Last_Name"]:"") ."[FileName]",

That code worked great!

I modified slightly below to get a dash between First_Name and FileName. (resulting in LastNameFirstName_image.jpg). And further added dash between Last_Name and First_Name after several attempts. (resulting in LastName_FirstName_image.jpg).

'FileName' => "".((isset($_POST["Last_Name"]))?$_POST["Last_Name"]:"") .""."_".((isset($_POST["First_Name"]))?$_POST["First_Name"]:"") ."_[FileName]",

thanks so much Jason!

you're welcome.
