Frequently asked questions
How do I add a regex pattern to a field?
Edit your form in Gravity Forms, select a supported field, and look for the “Regex Validation” section under the field settings. You can either select a preset pattern or enter your own custom regex.
Does it support Unicode characters?
Yes! All patterns use the /u flag for PHP and the u flag for JavaScript regex, enabling full Unicode property support like \p{L} for any letter in any language.
Can I add my own presets?
Yes, use the gf_regex_validation_presets filter: add_filter('gf_regex_validation_presets', function (array $presets): array { $presets['zip_code'] = [ 'label' => 'US Zip Code', 'pattern' => '/^\d{5}(-\d{4})?$/', 'message' => 'Please enter a valid US zip code.', ]; return $presets; });
Can I add support for additional field types?
Yes, use the gf_regex_validation_field_types filter: add_filter('gf_regex_validation_field_types', function (array $types): array { $types[] = 'number'; return $types; });
Is client-side validation secure?
Client-side validation provides instant user feedback but should never be relied upon for security. This plugin always performs server-side validation as well, which cannot be bypassed.
