Error Checking for DirectPay Form ecart5
I searched for error checking code on the forums but did not find any. Hence this request.
Is there code that I can use to check the form fields (Name, credit card, expiry date .. etc)
during the checkout process ? At least a Not empty check ?
Usually how is this implemented in eCart 5 ? If there is a form that captures data, shouldn't there be error checking to go with it ? If a client enters a bad number or forgets to enter some field it is useful for them to be shown what needs to be filled with an asterisk or a list of what was left blank.
USing ecart 5 with Paypal Pro. Using both Express checkout and a local Do Direct Pay option.
Any help will be really appreciated since my knowledge of php is rudimentary.
