Dear friends:

I have a field, where people can fill with one unique value (called CNPJ):

This filed must be validated with 3 rules:

1) The field checks whether the number has 14 digits.(no more no less)

2) If this number was submitted another time, it will not submit again, otherwise will submit without problems, so I think the submit button must check before all the submissions and check all the existent CNPJs (name I gave the field)

3) I would like to place mask in the CNPJ like this 90.496.126/0001-91

all numbers ##.###.###/####-##

Any Idea?

I am really lost!

Hello,

This can be done... however it will require a solid base of php and MySQL knowledge.

There are two ways of achieving this:

1. Create your own custom validation rule by adding a validation function to the components/com_rsform/controller/validation.php - here you will also be able to create a regular expression.

2. You can create a script, placed on the Scripts called on form process area... The script would be similar to the one posted here:
