Changeset 53395 for trunk/src/wp-includes/query.php

Timestamp:

05/14/2022 03:08:58 PM (3 years ago)

Author:

Message:

Query: Check if $wp_query is set in is_main_query().

This avoids a PHP fatal error and triggers a _doing_it_wrong() notice if is_main_query() is called too early, bringing consistency with all the other is_*() conditionals: is_single(), is_home(), etc.

Follow-up to [16947], [17068], [17083], [18699], [37985].

Props vdankbaar, nhadsall, johnbillion, costdev, thijsoo, teunvgisteren, timkersten655, SergeyBiryukov.
Fixes #55104.
