Changeset 57750 for trunk/src/wp-includes/class-wp-site-query.php

Timestamp:

03/02/2024 01:36:02 PM (13 months ago)

Message:

Query: Remove leading whitespace from certain database queries.

Unintended leading whitespace at the beginning of a raw MySQL query led to unexpected behavior such as broken pagination. Eliminating said whitespace avoids that.

Adds unit tests to prevent regressions.

Props wpfed, swissspidy, ironprogrammer, tadamarketing, afercia.
Fixes #56841.
