Running main loop 2 times with conditional statement

Question

I'm trying to achieve simple result. Run main loop 2 times, but first time for the one post with different layout, and second time for the rest posts with different layout. I found that condition 1 > $wp_query->current_post can show only the first post in my loop. But when I run loop again it starts with 3rd post and skipping the 2nd.

Here is the code:

<!-- Full Post -->
<?php if ( have_posts() ) :
    while ( have_posts() ) : the_post();
        // first post
        if( 1 > $wp_query->current_post ):
            get_template_part( 'template-parts/content', get_post_format() );
        else :
            break;
        endif;
    endwhile;
?>

<!-- Small Posts -->
<div class="row">
    <?php
      while( have_posts() ) : the_post();    
        get_template_part( 'template-parts/post-small', get_post_format() );      
      endwhile;
    ?>
</div>

Answer 1

I think you need to put wp_reset_postdata(); after your first endwhile; so that the loop can return to the start. Can see more about that function here: https://codex.wordpress.org/Function_Reference/wp_reset_postdata

Try reading up here: https://codex.wordpress.org/The_Loop#Multiple_Loops and in particular the section here: https://codex.wordpress.org/The_Loop#Multiple_Loops_in_Action and the use of: $do_not_duplicate
