    foreach($popularpostdata as $populardata)
        {
            $cur_id = $populardata->id;
            $cur_date = $populardata->post_date;
            $cur_date = date("F j, Y", strtotime($cur_date));
    ?>

      '.getCategoryLink().'';
        $post_mp = get_post($cur_id);
      ?>
      
title;?>
      

        
 post_author,$cur_id,$populardata->title,$cur_date); ?> 
        

          

            

              postcontent; //$content_post->post_content;
                    $content = apply_filters('the_content', $content);
                    $content = str_replace(']]>', ']]>', $content);
                    echo $content;
                    wp_link_pages( array(
                        'before'      => '
