I have been pretty impressed with the recent redesign at WebDesignerDepot and I am curious about the mechanics of their homepage. I like how they have featured post sections that break up the monotony of the page, but I haven't figured out how to incorporate something similar in my own designs. I'm guessing that they are using multiple loops and it seems like it's something like [main loop chronological] --- > [custom loop] ---> [main loop continues chronologically].

How would I break off into a custom loop and then continue where I left off in the main loop?

You can use current_post within the loop to track where you are and split the loop into multiple parts:

while ( have_posts() ) :
    the_post();

    // only output content if it's post 1 - 5
    if( 5 > $wp_query->current_post ):
        the_title();
    else :
        break;
    endif;

endwhile;

// do another query/loop
$custom_loop = new WP_Query( $args );
while( $custom_loop->have_posts() ) :
    // etc..
// snip....


// output posts 6 + of main query
while ( have_posts() ) :
    the_post();

    the_title();

endwhile;

You can also use $wp_query->rewind_posts(); to run the same loop again, or set current_post directly to start a loop at a specific post:

// start a loop at post 6
$wp_query->current_post = 5
while ( have_posts() ) :
    the_post();
    // etc..

Just remember that current_post is zero-indexed, it starts at zero, not 1.

Could you explain how this does not waste database resources. Is it because there are no wp_reset_postdata(); being called? –  tmyie Mar 2 at 17:45
    
@tmyie - I'm not sure I understand your question. the loop iterates over a query object, it doesn't itself do the querying. you can run through the same loop multiple times from a single initial query. –  Milo Mar 2 at 18:19
