Edit formulator pro php code to work on the free version of forminator

Job ID: 33404940

Budget: £10 – £20 GBP

I have a PHP code snippet that limits the date of birth on my formulator form to "Over 18 only".

I believe the snippet only works on forminator pro however & I do not have the pro version.

Can anyone make it work on the free version?
