Changeset 52206 for trunk/src/wp-includes/wp-db.php

Timestamp:

Message:

Database: Check if the $args[0] value exists in wpdb::prepare() before accessing it.

This avoids an Undefined array key 0 PHP warning if no values are passed to the method besides the query string.

Follow-up to [41470].

Props mjaschen.
Fixes #54453.
