我正在尝试设置wordpress滑块，如何在wordpress循环中获得精确的以下结果

            <div id="carousel">
                <img src="slide1.png" alt="" class="slide" />
                <img src="slide2.png" alt="" class="slide" />
                <img src="slide3.png" alt="" class="slide" />
            </div>

            <ul id="carousel-descriptions">
                <li class="desc current">Slide 1 Description Goes Here</li>
                <li class="desc">Slide 2 Description Goes Here</li>
                <li class="desc">Slide 3 Description Goes Here</li>
            </ul>

            <div id="carousel-controls">
                <span class="control current">Show Me<br>Slide 1</span>
                <span class="control">Show Me<br>Slide 2</span>
                <span class="control">Show Me<br>Slide 3</span>
            </div>

例如，我想在

 $my_query = new WP_Query(\'cat=49&showposts=4&orderby=RAND\');
while ($my_query->have_posts()) : $my_query->the_post();$do_not_duplicate = $post->ID;
?>

 above code

<?php endwhile; ?>

请告诉我是否有其他方法可以达到相同的效果，但orderby=RAND对我来说很重要

BR公司

<?php

$my_query = new WP_Query(\'cat=49&showposts=4&orderby=RAND\');
?>
<div id="carousel">
<?php
while ($my_query->have_posts()) : $my_query->the_post();
    // output each slide
endwhile;
?>
</div>
<?php

$my_query->rewind_posts();
?>
<ul id="carousel-descriptions">
<?php
while ($my_query->have_posts()) : $my_query->the_post();
    // output each desc
endwhile;
?>
</ul>
<?php

$my_query->rewind_posts();
// etc.
