Hi,
I am creating a referral form and have a field "referredby".
Now I want to accomplish the following.
- Whenever a suer clicks on a link which has "?referredby=abc", the field should automatically be filled by the text "abc"
- If I can make it read-only so it cant be changed and hide the field from displaying, thats even better.
Is this possible?
Then I can also use it for a referral program.
