I had following RealURL Configuration (part):
`'postVarSets' => array( '_DEFAULT' => array( 'level1' => array( array( 'GETvar' => 'tx_bitproducts_productview[industryLevel1]', 'lookUpTable' => array( 'table' => 'tx_bitproducts_domain_model_industry', 'id_field' => 'uid', 'alias_field' => 'industriename', 'addWhereClause' => ' AND NOT deleted ', 'useUniqueCache' => 1, 'useUniqueCache_conf' => array( 'strtolower' => 1, 'spaceCharacter' => '-' ), ) ), ), 'level2' => array( array( 'GETvar' => 'tx_bitproducts_productview[industryLevel2]', 'lookUpTable' => array( 'table' => 'tx_bitproducts_domain_model_industrylevel2', 'id_field' => 'uid', 'alias_field' => 'name', 'addWhereClause' => ' AND NOT deleted ', 'useUniqueCache' => 1, 'useUniqueCache_conf' => array( 'strtolower' => 1, 'spaceCharacter' => '-' ), ), ), ), ...`
which resulted in URLs like
.../level1/automotive/
and
.../level2/wheels/
all was handled by one Extbase Controller Action. How could an Extbase RouteEnhancer for TYPO3 9 could look like ? I would use Slug TCA for these fields.
Thanks for any hints !
