Field Validation and Formats

Description

Validation determines what kind of values and formatting may be entered into this field. Foxit eSign provides multiple choices of field validations for Text Fields, Text Box Fields, and Date Fields.

Custom Validation with RegEx 

(Available for Business Premium and Enterprise Plans)

RegEx (Regular Expression) searches through a String of text. RegEx may be used for fields containing content that need validation, such as credit card numbers or date of birth. Custom validation may be used on data fields when creating templates or a document. Select the field you would like to use for validation.  

In the Field Properties on the right, click the Validation then select Custom Validation from the dropdown list.  

There are two validation types, Error and Warning.  

• Error will not let the user confirm signing unless the Regular Expression matches exactly in that specific data field.  
• Warning will still let the user confirm signing but warns the user that their input may not match the field's Regular Expression exactly.  

Test a Regular Expression by entering a Test String and click Test Validation.
