我是wordpress新手，我想在自定义帖子类型查询中显示分页，但在前端不显示分页，有人能看到我的代码吗

  <?php 
// the query

$paged = ( get_query_var( \'paged\' ) ) ? get_query_var( \'paged\' ) : 1;

$wpb_all_query = new WP_Query(array(\'post_type\'=>\'german_post\', \'post_status\'=>\'publish\', \'posts_per_page\'=>12,\'order\' => \'DESC\',\'paged\' => $paged,\'orderby\' => \'date\'));

 ?>
    <?php if ( $wpb_all_query->have_posts() ) : ?>
    <div class="row" id="post_content">
      <?php while ( $wpb_all_query->have_posts() ) : $wpb_all_query->the_post(); ?>
      <div class="col-md-4 col-sm-6 col-xs-12" id="post_container">
        <div class="post-box" > 
            <a href="<?php the_permalink(); ?>" class="clickable_box"></a>
            <a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>">
          <div class="post-img" style="background-image:url(<?php the_post_thumbnail_url(); ?>)">
            <?php if ( has_post_thumbnail() ) : ?>
            <?php endif; ?>
          </div>
          </a>
          <div class="post-small-details"> <span class="interests">
            <ul class="list-inline">
