Description

Use case

You can a step input to follow a specific pattern, e.g. prevent the user from typing certain characters 

Example

We want to prevent special characters (&/*_) to be entered in the Lot Number step,

Only alfa-numeric values are to be allowed.

How to set it up

The change is made in the workflows section of Mobile Configuration Files.

Use "inputFormat" followed by a regular expression for what you want to achieve

...

Examples

• Match only alfa-numeric characters, blocking special characters
  • ^\w+$will match only alfa-numeric values and therefore blocks special characters 

• Validate date is in format DDMMYY where YY must be 20 or higher

  • (0[1-9]|[1-2][0-9]|3[0-1])(0[1-9]|1[0-2])(2[1-9]|3[0-2])

    
    

Use an online editor to test your regular expressions see Barcode converter - Regular Expressions
