Changeset 43492 for branches/4.9/tests/phpunit/tests/term/query.php

Timestamp:

Message:

Taxonomy: Ensure that invalid term objects are discarded in WP_Term_Query.

The get_term() mapping may result in term objects that are null or
WP_Error when plugins use get_term or a related filter. Since null
and error objects are not valid results for a term query, we discard
them.

Props GM_Alex.
Merges [43049] and [43491] to the 4.9 branch.
Fixes #42691.
