We using gravity forms, we need to check in a Gravity HTML field if a value is correct. This value need to be fetched from the database. Sounds simple, but believe me, few developers failed already.
Let me know if you are the gravity form expert and able to make custom changes in this plugin.
I'm a GF pro. See my Portfolio at Codecanyon : https://codecanyon.net/user/naranili/Portfolio Where do you need to check this value ? At the Form-Builder or at the Front-end ?
