Hello. web designer premium 17.
I want to insert an email contact form on my site.
I have always used jotform.
Now I want to use a form like this: https://xaratemplates.com/own-contact-form-using-php/
The form must have some obligatory fields.
The form must have a field with the name "data processing" and with the value "I accept"
(usually this is a checkbox or a radio)
How can I do?
