Common Regex Validation codes

If you want to add validation to any of your fields, you need to know a little bit about Regex Validators. Once you know what kind of validation you want to add, you can click the "Show Advanced Settings" menu under the field you want to add validation to and put in your Regex Validation code. 

This documentation page is simply a compiled table of different validation codes that our users have put in place to ensure that data entered matches what they want it to. If you have a validation code that you've used that you think would be good to add here, please email us at support@timetap.com and let us know so we can add it here:
