Handling undefined index notices in wp_old_slug_redirect

[nirajkvinit]

Following variables $wp_query->query_vars['name'], $wp_query->query_vars['year'], $wp_query->query_vars['monthnum'], and $wp_query->query_vars['day'] in the function wp_old_slug_redirect should be checked with isset. Else undefined index notices may arise.

Under what circumstances are these values not set?

Using $wp_query->get( 'name' ) should suffice, as this function already does an isset check.

You are correct! In my virtual pages, I faced this issue. Setting up query vars solved the issue! :p
