Methods
prepare()
Prepare TCA
public
prepare(array<string|int, mixed> $tca) : array<string|int, mixed>
This class is typically called within bootstrap with empty caches after all TCA files from extensions have been loaded. The preparation is then applied and the prepared result is cached. For flex form TCA, this class is called dynamically if opening a record in the backend.
See unit tests for details.
Parameters
- $tca : array<string|int, mixed>
Return values
array<string|int, mixed>configureCategoryRelations()
Prepares TCA configuration of type='category' fields.
protected
configureCategoryRelations(array<string|int, mixed> $tca) : array<string|int, mixed>
It adds some TCA config settings so category fields end up with similar config as type='select' field, but in a more restricted way. Some settings could also be set in TCA directly, but some fields can not be overridden, e.g. foreign_table.
This also sets necessary MM properties, in case relationship is set to "manyToMany" (which is the default).
Finally all category fields with a "manyToMany" relationship are added to the MM_oppositeUsage of sys_category "items".
Important: Since this method defines a "foreign_table_where", this must always be executed before prepareQuotingOfTableNamesAndColumnNames().
Parameters
- $tca : array<string|int, mixed>
Return values
array<string|int, mixed>prepareQuotingOfTableNamesAndColumnNames()
Quote all table and field names in definitions known to possibly have quoted identifiers like '{#tablename}.{#columnname}='
protected
prepareQuotingOfTableNamesAndColumnNames(array<string|int, mixed> $tca) : array<string|int, mixed>
