Firstly, you are invoking an infinite loop, which causes the memory exhaustion. To avoid it, put the following at the beginning of your function: // avoid infinite loop remove_action( ‘pre_get_posts’, __FUNCTION__ ); It makes sure the you are not hooking it into pre_get_posts over and over again, re-initiating your get_posts() call over and over again. … Read more
<ul class=”products”> <?php $args = array( ‘post_type’ => ‘product’, ‘posts_per_page’ => 12 ); $loop = new WP_Query( $args ); if ( $loop->have_posts() ) { while ( $loop->have_posts() ) : $loop->the_post(); wc_get_template_part( ‘content’, ‘product’ ); endwhile; } else { echo __( ‘No products found’ ); } wp_reset_postdata(); ?> </ul><!–/.products–>
That’s pretty easy. All you need is this: global $wp_query; $my_posts = $wp_query->posts;
