Question

I’ve got post type called “Portfolio” and single-portfolio.php file to handle it (it’s WordPress). When I use there something like that it works like expected:

$post_id = $post->ID; //returns ID of current portfolio post. Good!

BUT when I post short query like this in the middle:

$post_id = $post->ID; //returns ID of current portfolio post. Good!
wp_reset_query();
query_posts('posts_per_page=4');
    if ( have_posts() ) : while ( have_posts() ) : the_post();
            the_id(); //returns ID of standard blog post
        endwhile;
    endif; 
wp_reset_query();
$post_id = $post->ID; //returns ID of last BLOG post. Wrong!

I’m only concerned about $post_id variable in above example. I want it to always return correct ID of current PORTFOLIO post and not be dependent on other queries. How do I achieve that?

The wp_reset_query function does reset the global $post variable as well, but only based on the global $wp_query variable. That still is modified, probably due to one of the little flaws in WordPress. In your case I’d say a simple WP_Query::rewind_posts() should do it:

wp_reset_query();
$wp_query->rewind_posts();
$post_id = $post->ID;

Also you should consider to create a second loop, not overwrite the first one.
