How to validate a form response? Regex?

I want to use the form to update my database.

But how can I use Regex in a field so that it doesn’t enter values that aren’t in the rule?

Can I use a regex in the specific field?

Hi @rafaelrodrigues

Did you have a look at the “regex_replace” function

With the help of the “regex_replace” function you could remove out any entries in the field that do not match the particular field.

Hey @rafaelrodrigues ,

You can’t apply regex rules to specific fields, but you can filter rows that have been submitted incorrectly using what @Harsh has described.

If you have any questions to how this would work in practice let us know and provide us with some more details in regards to your table structure so we can help out :).
