eval¶

eval ('type' => 'email') ¶

Path: $GLOBALS['TCA'][$table]['columns'][$field]['config']
type: string (list of keywords)
Scope: Display / Proc.

Configuration of field evaluation.

Some of these evaluation keywords will trigger a JavaScript pre- evaluation in the form. Other evaluations will be performed in the backend. The evaluation functions will be executed in the list-order. Keywords:

unique: Requires the field to be unique for the whole table. Evaluated on the server only.

Note

When selecting on unique-fields, make sure to select using AND pid>=0 since 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!
uniqueInPid: Requires the field to be unique for the current PID among other records on the same page. Evaluated on the server only.
