WP Custom post loops.txt

Use WP_Query when you need to create a paginated query
Use get_posts() to create static, additional loops (e.g. a list of a few recent posts on a homepage, etc.)


############## DEFAULT LOOP
<?php if ( have_posts() ) : ?>
   <?php while ( have_posts() ) : the_post(); ?>
      <h2><?php the_title(); ?></h2>     ###### POST TITLE
      <?php the_content(); ?>                ###### POST CONTENT
   <?php endwhile; ?>
   <?php the_posts_navigation(); ?>     ##### GETS NAV INFO
<?php else : ?>
   <h2>Nothing found!</h2>
<?php endif; ?>

############### TO MODIFY LOOP / MAKE QUERYS
  
  <?php
   $args = array( 'post_type' => 'product', 'order' => 'ASC' );    ######## WHAT SPECIFICLY TO PULL
   $products = new WP_Query( $args ); // instantiate our object      ######## 
?>
<?php if ( $products->have_posts() ) : ?>        
   <?php while ( $products->have_posts() ) : $products->the_post(); ?>       ######### IF THERE ARE POSTS/ POST
      <?php /* ############ Content of the queried post results goes here */ ############# ?>
   <?php endwhile; ?>
   <?php wp_reset_postdata(); ?>
<?php else : ?>
      <h2>Nothing found!</h2>
<?php endif; ?>

############### GET_POSTS . BEST PRACTICE ####################

We pass $args into get_posts() just like we do WP_Query, but we handle the output a bit differently:

<?php
   $args = array( 'post_type' => 'product', 'order' => 'ASC' );
   $product_posts = get_posts( $args ); // returns an array of posts
?>           ############# POSTS IS THE ITERANT DATA         
<?php foreach ( $product_posts as $post ) : setup_postdata( $post ); ?>
#EG: "<H2> {$POST} </H2>'
   <?php /* Content from your array of post results goes here */ ?>
<?php endforeach; wp_reset_postdata(); ?>


############## THE ARGUMENTS ARE THE KEY
$args = array(
   'order' => 'ASC',
   'posts_per_page' => 8,
   'post_type' => 'product',
   'tax_query' => array(
      array(
         'taxonomy' => 'product-type',
         'field'    => 'slug',
         'terms'    => 'bread',
      ),
   ),
);
$products = new WP_Query( $args );
