의 클래스 전환하지만, 아무것도 내 슬라이더에 대한 코드 아래 사용하고,하지 $ featuredPosts가 유효한 int 필드인지 생각해보십시오. 아마도 이것은 불평 할 것입니다. 또한 have_posts()와 함께 이미 여러 번 게시물을 반복합니다.

<?php 
       $featuredPosts = new WP_Query(); 
       $featuredPosts->query('showposts='.get_option('mp_slides_no').'&category_name='.get_option('mp_featured_cat').''); 

       //for($i=1; $i<=$featuredPosts; $i++) { // second for() loop for post slides 
       while ($featuredPosts->have_posts()) : $featuredPosts->the_post(); // loop for posts 
       ?>
