I have a header and a footer menu (they're the same: Primary Menu). When I'm on a page, wordpress adds classes like current_page_menu. But on pages where I use the query_posts() function the menus after this function dont have those classes added like current_page_menu etc.

Here is my code that is causing the bug:

  $title_slug = strtolower(str_replace( " ", "-" , the_title_attribute('echo=0') ) );
  $id_obj = get_category_by_slug($title_slug);
  $cat_id = $id_obj->term_id;
  query_posts( 'cat='.$cat_id.'&post_status=publish,future&paged='.get_query_var('paged') );

This code is very useful, though. As it ensures to create a category page by adding a page and selecting the category page template instead of just a link to that category. I had to do this because my category pages need to have child pages.

I'd be greatful if anyone knows a solution!

The issue is caused by the query_posts function, this function alters the global $wp_query which the menu walker uses to check and add classes like current_page_menu to menu items.

A solution would be to write a new custom query and loop through that than using query_posts.

$title_slug = strtolower(str_replace( " ", "-" , the_title_attribute('echo=0') ) );
$id_obj     = get_category_by_slug($title_slug);
$cat_id     = $id_obj->term_id;
$args       = 'cat='.$cat_id.'&post_status=publish,future&paged='.get_query_var('paged');
// The Query
$the_query = new WP_Query( $args );

// The Loop
if ( $the_query->have_posts() ) : ?>
    <?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
            //YOUR CONTENT
    <?php endwhile; ?>
        /* Restore original Post Data */
    <?php wp_reset_postdata(); ?>
<?php endif; ?>


  • Thank you very much! I didn't know the walker function for the menu classes was using the global query object. Thanks! Feb 10, 2017 at 12:56
