Changeset 31275 for trunk/tests/phpunit/tests/term/getTerms.php

Timestamp:

01/24/2015 06:47:30 PM (10 years ago)

Message:

Introduce 'childless' parameter to get_terms().

This new parameter allows developers to limit queried terms to terminal nodes -
ie, those without any descendants.

As part of the improvement, some internal logic in get_terms() has been
consolidated. Parameters that resolve to a NOT IN clause containing term IDs
('exclude', 'exclude_tree', and 'childless') are now parsed into a single
"exclusions" array before the SQL clause is generated.

Props theMikeD, horike.
Fixes #29839.
