Zebra Print Bikini & gform_pre_submission

I need to take a text that the user inputs into a form, populate a hidden field and slightly manipulate the data prior to saving into the database.

I want "Zebra Print Bikini" to become "zebra-print-bikini" in a different hidden field.

I'm new to php. It seems if the 2nd field in my form contained "Zebra Print Bikini", I would I need to do something like this:
```
$newVariable = str_replace(" ", "-", input_2);
$newnewVariable = strtolower($newVariable)
```
In Gravity Forms I think I need to use gform_pre_submission. If the hidden field I want to place the new variable in is the first field in my form, I think I'd need to do something like this:
```
add_action("gform_pre_submission", "pre_submission_handler");

function pre_submission_handler($form){
$newVariable = str_replace(" ", "-", input_2);
$newnewVariable = strtolower($newVariable)
$_POST["input_1"] = $newnewVariable;
}
```
And, this goes in my bp_custom.php since I'm using BuddyPress?

Of course, I tried this and it didn't work so I'm asking for assistance. Appreciate it!

It's not all that pretty, but this is now working!

add_action("gform_pre_submission_1", "pre_submission_handler");

function pre_submission_handler($form){

global $_POST;

$VariableForceLowerCase = strtolower($_POST["input_2"]);
$VariableSpaceToDashes = str_replace(" ", "-",
$VariableForceLowerCase);

$_POST["input_21"] = $VariableSpaceToDashes;
}

I struggled to figure out what the input_# was for the field I was working on. Any tip on easily knowing what the field number is?

You'd get the field input # by inspecting the form markup and seeing what the ID is for that input.
