This module provides a way to compare the values of two fields within a webform. You can configure it to validate that specific fields either match or do not match each other, offering flexibility in how data types are handled during the comparison.
About
Configurable handler for comparing two fields on a webform.
Installation and Configuration
Install and enable as any other drupal 8 module, no special requirements.
To configure the interface
- Navigate to your webform's handlers page (e.g. /admin/structure/webform/manage/form_id/handlers).
- Click [+ Add handler] button.
- Click [Add handler] next to "Validate Entries by Comparing 2 fields"
- Enter the field names and comparison operator and data type information
- Machine name is generally just the key from the form build page.
- Allowable operators are "==", "!=", "<>", "<", "<=", ">", and ">=".
While "===", and "!==" are included for completeness, they are of
little value as units are hard converted before comparison. - Nearly all webform values are strings by default, choose how they
should be handled if they are different, this is especially critical for
dates. Both sides of the comparison will be treated as the same type. - At this time, both integers and floating point numbers are compared as floats.
- Click [Save]
- This handler can be added multiple times one one form by repeated the above steps.
