Как подгружать посты Ajax в Wordpress?

<div class="isotope">
		<?php $photo_query = new WP_Query (array('paged' => get_query_var('paged'), 'post_type' => 'photo', 'posts_per_page'=> 11, 'orderby'=>'rand')); ?>
			<?php if($photo_query->have_posts()) { 
					while($photo_query->have_posts()) { 
						$photo_query->the_post(); 
						$id = get_the_ID(); 
						$portfolio_cats = wp_get_object_terms($id, 'photo-cats');
						$url = wp_get_attachment_url(get_post_thumbnail_id($post->ID));
                    	$image  = aq_resize($url, 400, 259, true);
						global $post;
						?>
			//Отдельный пост
			<div class="element-item <?php foreach($portfolio_cats as $portfolio_cat) { echo ' term_id_' . $portfolio_cat->term_id; } ?>" data-category="transition">
				<a href="<?php the_permalink();?>">
					<img src="<?=$image;?>" alt="item" height="100" class="img-responsive">
					<div class="caption">
						<h3 class="name"><?php the_title();?></h3>
						<p><?=strip_tags(mb_substr($post->post_content, '0', '150')); ?>...</p>
					</div>
				</a>
			</div>
                         //закончился пост
			<?php }?>
	    <?php }?>
	    <?php
        wp_reset_query();
        wp_reset_postdata();
        ?>
		<div class="element-item <?php foreach($portfolio_categories as $cat) { echo ' term_id_' . $cat->term_id; }?> " data-category="actinoid">
			<a href="<?php echo get_page_link(10); ?>" target="_blank" class="more-works-btn">
