- eval ('type' => 'email')¶
string (list of keywords)
Display / Proc.
Configuration of field evaluation.
Requires the field to be unique for the whole table. Evaluated on the server only.
When selecting on unique-fields, make sure to select using
AND pid>=0since the field can contain duplicate values in other versions of records (always having PID = -1). This also means that if you are using versioning on a table where the unique-feature is used you cannot set the field to be truly unique in the database either!
Requires the field to be unique for the current PID among other records on the same page. Evaluated on the server only.
