First, don’t use query_posts(). Just get rid of the call entirely. It will break things. Second: I tried adding the following before the query_posts ( function but it does nothing. Callbacks and add_action() calls belong in functions.php, not in the template file. If you’ve put it directly in home.php, remove it from there, and put … Read more
Role Scoper is a pretty good plugin to restrict category post access to users. It allows you to assign restrictions and roles to specific pages, posts or categories, which is what you said you need
If you want to use the function to output the code somewhere: function displayImage($currentPost) { // Show the featured icon only if current post is in “featured” category if ( in_category ( ‘featured’, $currentPost ) ) { $output=”<a href=”https://wordpress.stackexchange.com/questions/58811/<?php the_permalink(); ?>”> <span class=”featured_icon”> <img src=”<?php bloginfo(“template_directory’); ?>/images/featured_icon.png” /> </span> </a>’; } else { $output=”” }; … Read more

It’s a hack of wp_dropdown_categories, but it works.
You could use get_categories(). Returns an array of category objects matching the query parameters. Arguments are pretty much the same as wp_list_categories and can be passed as either array or in query syntax. // Fetch parent categories $parent_categories = get_categories( ‘parent=0’ ); foreach ( $parent_categories as $parent_category ) { // Fetch child categories $args = … Read more
