This PR resolves the issue where archive pages with multiple post types throws a PHP array to string conversion warning.
get_query_var
can return an array or a string, depending on the query. Previously we were assumingget_query_var( 'post_type' )
would only ever return a string. Most of the time this would be true, but there are cases where it is not.This PR adds tests against this scenario and adds handling that runs a
is_array
check onget_query_var( 'post_type' )
and if it is an array, emits surrogate keys for each post type.this PR also creates a new Factory that extends the base WP Unit Test factory to avoid dynamically creating it and throwing PHP 8 deprecation warnings.
