$WB*$NumericValueToBeMultipliedBy
Description
This is a form field value prefix for doing
mathematical operation of multiplication with values of fields of numeric type.
When WBSP engine receives a WBF_tablefieldname form field value
with this prefix for database table field of numeric type, instead of replacing
the old value with new one, it will multiply existing value with the new value
(so new value stored in the database is
OldDatabaseTableFieldValue*NewFormValue)
Here's an example:
After running this example (and pressing the "Double the price" button), field Price in updated record of table Titles will be multiplied by 2.
