MM

New in version 11.4: TCA table column fields that define ['config']['MM'] can omit the specification of the intermediate MM table layout in ext_tables.sql. The TYPO3 database analyzer takes care of proper schema definition.

Extensions are strongly encouraged to drop CREATE TABLE definitions from the ext_tables.sql file for those intermediate tables referenced by TCA table columns. Dropping these definitions allows the Core to adapt and migrate definitions if needed.

MM (type => select)
Path

$GLOBALS['TCA'][$table]['columns'][$field]['config']

Type

string (table name)

Scope

Proc.

This value contains the name of the table in which to store a MM relation. It is used together with foreign_table.

The database field with a MM property only stores the number of records in the relation.

Please have a look into the additional information in the MM common property description.

Examples
