Using php string function on update and/or insert

Question

So, for instance, I want to place a month/day in a column but I want the insert or update to strip out any forward-slash character that might be submitted.
How do I get str_replace() to be applied on insert or update to prevent the insertion of a forward-slash.
I am having trouble figuring out to what I should apply function. There's nothing in the form's value field and even if I echo in a variable or something like this:
echo $row_rssubscription_payment_copy['expirationDate'];
I have trouble "seeing" what the syntax should be. My guesses are all wrong.
Will someone please lend a hand.
Thanks very much!

Hi alterity,
if you´d use ADDT´s datepicker, you wouldn´t need to worry about that :-)
honestly, if a column like "expirationDate" is supposed to store the year-month-day value in a mysql compatible format, I can´t think of any reason to not use the datepicker.
However it´s possible to apply stuff like that to a certain transaction value before it´s getting submitted to a table -- here´s a str_replace example which would replace a forward slash (/) with a hyphen:
$tNG->setColumnValue("columnname_here", str_replace('/','-',$tNG->getColumnValue("columnname_here")));
All you´d need to do, is to embed such things in a Custom Trigger and make sure it´s defined as BEFORE trigger.
