Iam using the following code to get a custom field results if user click a button. <a href="#mobile" rel="facebox"> <img src="<?php bloginfo('template_directory'); ?>/images/mobile.png" /> </a> <div id="mobile" style="display:none;"> <?php echo get_post_meta($post->ID, "key12", true); ?> </div> Code (markup): I have 4 posts in this page. If i click first result button this is display correct result. If i click the next others, all click is displaying the first post of custom field. How to clear the first custom field cache?.
