Tag: posts

In page-images.php template I have created this code which displays a list of posts which belong to a category and order them by meta value. So basically it is like a category page, generally nothing special except that each post isn’t shown as a single featured image but with all its images like this: This code works but I ask myself how can it be more optimized? Since it has nested WP_Query. Page generates 100 queries and it should be a paginated list like this for each category and for many variations (depending on meta key).

$  query = new WP_Query( array(     'posts_per_page' => 25,      'cat' => 102, // Category ID     'meta_key' => 'rod', // Order by meta field value     'orderby'   => 'meta_value',     'order' => 'ASC',     'post_status' => 'publish',     'meta_query' => array( // Meta value should exists             array(                 'key' => 'rod',                 'value'   => array(''),                 'compare' => 'NOT IN'             )         )     ));  // Inside loop for each post get its images if ($  query->have_posts() ) {     while($  query->have_posts()) {     $  query->the_post();          $  args = array(             'posts_per_page' => -1,              'post_type' => 'attachment',             'post_mime_type' => 'image',             'post_status' => 'any',              'post_parent' => get_the_ID(),             'order' => 'DESC'             );         $  attachments = new WP_Query($  args);             ?>           <div class="col-md-10">             <?php // each loop has a title, meta field and images             <h2><?php echo get_the_title($  key); ?></h2>             <p><?php the_field('latinsko_ime', $  key); ?></p>              <div class="row">                 <?php while($  attachments->have_posts()) : $  attachments->the_post(); ?>                 <div class="col-md-3">                      <a href="<?php the_permalink(); ?>">                         <?php echo wp_get_attachment_image(get_the_ID(), 'category__loop', false, array('class' => 'img-fluid')); ?>                     </a>                  </div>                 <?php endwhile; ?>             </div>          </div>      <?php      }  } 

I have tried removing nested WP_Query and for each loop retrieve images like this $ gallery = get_post_gallery_images( get_the_ID() ); but in this case I have even more queries (127)
