Validation Regex Property in Forms Builder

Validation Regex is the regular expression pattern to validate the input. Use a site like http://RegExLib.com to search and test Regex patterns, or construct your own with Regex tools like Expresso. If the user input does not produce a Regex match, the "Validation message" will be displayed.

Examples

Regex that enforces a minimum of 11 digits for a phone number where the first digit must be "1":

1\d{10} 

Regex that enforces a phone number in the format (###)###-####:

^\([0-9]{3}\)[0-9]{3}\-[0-9]{4}$ 

Regex that matches a hyphen-separated social security number:

^\d{3}-\d{2}-\d{4}$
