Php 自定义post类型循环

我需要一些关于这个剧本的指导

我正在处理一个自定义的post类型循环，但我一直在研究如何将这个静态html转换为php循环

<?php 
    $loop = new WP_Query(array('post_type' => 'project', 'posts_per_page' => -1));
    $count =0;
?>
<!--Text Sliders-->
<div class="ps-contentwrapper">
    <?php if ( $loop ) : 

        while ( $loop->have_posts() ) : $loop->the_post(); ?>
<?php
$terms = get_the_terms( $post->ID, 'tagproject' );

if ( $terms && ! is_wp_error( $terms ) ) : 
    $links = array();

    foreach ( $terms as $term ) 
    {
        $links[] = $term->name;
    }
    $links = str_replace(' ', '-', $links); 
    $tax = join( " ", $links );     
else :  
    $tax = '';  
endif;
?>
    <?php $infos = get_post_custom_values('_url'); ?>
    <div class="ps-content">
        <h2><?php the_title(); ?></h2>

        <p><?php echo get_the_excerpt(); ?></p>
    </div><!--end of ps-content-->


</div><!-- /ps-contentwrapper -->

<!--Image Sliders-->
<div class="ps-slidewrapper">

    <div class="ps-slides">
        <?php
            $url = wp_get_attachment_url( get_post_thumbnail_id($post->ID) );
        ?>
        <div style="background-image: url(<?php echo $url; ?>);"></div>
    </div>
        <?php endwhile; else: ?>
    <?php endif; ?>
    <nav>
        <a href="#" class="ps-prev" style="background-image: url(images/home/1.jpg);"></a>
        <a href="#" class="ps-next" style="background-image: url(images/home/2.jpg);"></a>
    </nav>  

将代码用于上一篇文章图像url：


太棒了。我一直在学习这个教程，你的教程为我节省了很多时间。谢谢。单击“下一步”和“上一步”按钮后，您的代码如下：
<div class="ps-slides">
                    <?php
                        $url = wp_get_attachment_url( get_post_thumbnail_id($post->ID) );
                    ?>
                    <div style="background-image: url(<?php echo $url; ?>);"></div>
                </div><!--end of ps-slides-->

<div class="ps-contentwrapper">
                <?php if (have_posts()) : while (have_posts()) : the_post(); ?>
                    <div class="ps-content">
                        <h2><?php the_title(); ?></h2>
