Changeset 58812 for trunk/src/wp-includes/class-wp-walker.php

Timestamp:

07/26/2024 07:54:26 AM (10 months ago)

Message:

General: Cast $max_depth and $depth to an integer in the Walker class.

This ensures that the arguments are correctly interpreted when passed as a query string, i.e. when wp_parse_args() is involved. For example, wp_list_pages( 'depth=0' ) should display a list of all pages to the maximum depth.

Follow-up to [57848].

Props freibergergarcia, peterwilsoncc, ahortin.
Fixes #61749.
