Form Element Validation

Issue/Question

How do I ensure that a form element is required or ensure a text based input matches a specified format?

Environment

• Web CMS

Resolution

Use the Form Element Settings to add requirements to it.
Note: Not all settings apply to every form element, for example checkbox and radio options cannot follow a pattern or have a minimum/maximum length.

1. Click Content tab.
2. Select Forms.
3. Use Filter to locate your form in the list.
4. Click Form Title.
5. Check out the form.
6. Click Edit tab.
7. Select the field you want to edit to expand Settings.
8. Locate the Validation section and use any of the optional settings:
   1. Enter an Error Message to replace the default message with something more specific.
   2. Toggle Required to On and the user must complete the field before submitting the form.
   3. Add a Maximum or Minimum character Length for the field.
   4. Use the Pattern input to include a Regular Expression for advanced validation.

Patterns:

• Phone Number:  ^(\(\d{3}\)\s?|\d{3}[-.]?)\d{3}[-.]?\d{4}$
• WKU Email: ^([A-Za-z0-9._%+-]+@wku\.edu|[A-Za-z0-9._%+-] +@topper\.wku\.edu)$
• WKU Employee Email: ^[A-Za-z0-9._%+-]+@wku\.edu$ 
• TopperMail Email:  ^[A-Za-z0-9._%+-]+@topper\.wku\.edu$
• WKUID (800 number):  ^(800|801)\d{6}$
