To turn on and require validation rules for a form field, please go to Actions >> Validation Options:

 

Enable validation here:

Validation Rules:

  • Min/Max Characters

Restricts how many characters a field can have.

On the right side, the error message can be added.

It will look like this in the front end:

  • Numerical Value Range

Set numerical range this field's value needs to fall within.

It will look like this in the front end:

  • Regular Expression

This is an advanced setting for developers to input REGEX rules.

So for example, the regex that is in the placeholder above:

/^[a-zA-Z0-9_.]+$

It means that the content has to be any combination of lowercase or uppercase letters (A - Z), numbers, underscores, and periods.

No other characters would be accepted. Use without the leading or trailing slash /.

NOTE: If no error message is added, the system will show general error messages. These messages are text labels and are edited by going to Settings >> Text Labels.

Then at the right top in the search bar, please type "Form validation" and all labels related to these messages will show up.
