具有自定义帖子类型和分页的多个 WP_Query

Question

基本上我设置了两种帖子类型，“狗”和“猫”。我有一个带有两个 WP_Query 循环的页面模板，显示每个循环中每个帖子类型的两个最新帖子。以下是我注册帖子类型的方式：

<?php
  function cat_post_type() { 
    register_post_type( 'cat',
      array('labels' => array(
        'name' => __('Cats', 'bonestheme'),
        'singular_name' => __('Cat', 'bonestheme'),
        'all_items' => __('All Cats', 'bonestheme'),
        'add_new' => __('Add New', 'bonestheme'),
        'add_new_item' => __('Add New Cat', 'bonestheme'),
        'edit' => __( 'Edit', 'bonestheme' ),
        'edit_item' => __('Edit Cats', 'bonestheme'),
        'new_item' => __('New Cat', 'bonestheme'),
        'view_item' => __('View Cat', 'bonestheme'),
        'search_items' => __('Search Cat', 'bonestheme'),
        'not_found' =>  __('Nothing found in the Database.', 'bonestheme'),
        'not_found_in_trash' => __('Nothing found in Trash', 'bonestheme'),
        'parent_item_colon' => ''
        ),
        'description' => __( 'This is the cat post type', 'bonestheme' ),
        'public' => true,
        'publicly_queryable' => true,
        'exclude_from_search' => false,
        'show_ui' => true,
        'query_var' => true,
        'menu_position' => 8,
        'rewrite'  => array( 'slug' => 'cat', 'with_front' => false ),
        'has_archive' => 'cats',
        'capability_type' => 'post',
        'hierarchical' => false,
        'supports' => array( 'title', 'editor', 'thumbnail' )
       )
    );
  } 
  add_action( 'init', 'cat_post_type' );

  function dog_post_type() { 
    register_post_type( 'dog',
      array('labels' => array(
        'name' => __('Dogs', 'bonestheme'),
        'singular_name' => __('Dog', 'bonestheme'),
        'all_items' => __('All Dogs', 'bonestheme'),
        'add_new' => __('Add New', 'bonestheme'),
        'add_new_item' => __('Add New Dog', 'bonestheme'),
        'edit' => __( 'Edit', 'bonestheme' ),
        'edit_item' => __('Edit Dogs', 'bonestheme'),
        'new_item' => __('New Dog', 'bonestheme'),
        'view_item' => __('View Dog', 'bonestheme'),
        'search_items' => __('Search Dog', 'bonestheme'),
        'not_found' =>  __('Nothing found in the Database.', 'bonestheme'),
        'not_found_in_trash' => __('Nothing found in Trash', 'bonestheme'),
        'parent_item_colon' => ''
        ),
        'description' => __( 'This is the dog post type', 'bonestheme' ),
        'public' => true,
        'publicly_queryable' => true,
        'exclude_from_search' => false,
        'show_ui' => true,
        'query_var' => true,
        'menu_position' => 8,
        'rewrite'  => array( 'slug' => 'dog', 'with_front' => false ),
        'has_archive' => 'dogs',
        'capability_type' => 'post',
        'hierarchical' => false,
        'supports' => array( 'title', 'editor', 'thumbnail' )
       )
    );
  } 
  add_action( 'init', 'dog_post_type' );
?>

下面是我显示帖子类型的方式：

<?php
  $cat_query = new WP_Query(
    array(
      'posts_per_page' => 2,
      'post_type' => 'cat'
    )
  );
  if($cat_query->have_posts()) :
?>

  <div>
    <?php
      while($cat_query->have_posts()) :
      $cat_query->the_post();
    ?>
      <div>
        <a href="<?php the_permalink(); ?>">
          <?php the_title(); ?>
        </a>
      </div>
    <?php
      endwhile;
      wp_reset_postdata();
    ?>
  </div>

<?php endif; ?>

<?php
  $dog_query = new WP_Query(
    array(
      'posts_per_page' => 2,
      'post_type' => 'dog'
    )
  );
  if($dog_query->have_posts()) :
?>

  <div>
    <?php
      while($dog_query->have_posts()) :
      $dog_query->the_post();
    ?>
      <div>
        <a href="<?php the_permalink(); ?>">
          <?php the_title(); ?>
        </a>
      </div>
    <?php
      endwhile;
      wp_reset_postdata();
    ?>
  </div>

<?php endif; ?>

我希望它们能够与自己的分页共存，就像 here (watch the video) 一样，但这似乎只适用于普通的 WP 帖子，而不适用于自定义帖子类型。如果有人对如何实现这一点有任何想法，那将是惊人的，因为这让我发疯！

我几乎用下面的代码实现了它，但它有问题，例如，如果我在两个分页上都转到第三页，然后在 cat post type 分页上单击第一页，它将转到它已经存在的相同 URL上：

<?php
  $paged1 = isset( $_GET['paged1'] ) ? (int) $_GET['paged1'] : 1;
  $cat_query = new WP_Query(
    array(
      'posts_per_page' => 2,
      'post_type' => 'cat',
      'paged'  => $paged1
    )
  );
  if($cat_query->have_posts()) :
?>

  <div>
    <?php
      while($cat_query->have_posts()) :
      $cat_query->the_post();
    ?>
      <div>
        <a href="<?php the_permalink(); ?>">
          <?php the_title(); ?>
        </a>
      </div>
    <?php
      endwhile;
      echo paginate_links(
        array(
          'format'   => '?paged1=%#%',
          'current'  => $paged1,
          'total'    => $cat_query->max_num_pages,
          'add_args' => array( 'paged2' => $paged2 )
        )
      );
      wp_reset_postdata();
    ?>
  </div>

<?php endif; ?>

<?php
  $paged2 = isset( $_GET['paged2'] ) ? (int) $_GET['paged2'] : 1;
  $dog_query = new WP_Query(
    array(
      'posts_per_page' => 2,
      'post_type' => 'dog',
      'paged'  => $paged2
    )
  );
  if($dog_query->have_posts()) :
?>

  <div>
    <?php
      while($dog_query->have_posts()) :
      $dog_query->the_post();
    ?>
      <div>
        <a href="<?php the_permalink(); ?>">
          <?php the_title(); ?>
        </a>
      </div>
    <?php
      endwhile;
      echo paginate_links(
        array(
          'format'   => '?paged2=%#%',
          'current'  => $paged2,
          'total'    => $dog_query->max_num_pages,
          'add_args' => array( 'paged1' => $paged1 )
        )
      );
      wp_reset_postdata();
    ?>
  </div>

<?php endif; ?>

成功！我试图在定义之前调用$paged2 变量，$paged1 和$paged2 都必须在两个循环开始之前定义。以下代码是最终循环（出于测试目的，我还更改了正在使用的帖子类型名称）：

<?php
  $paged1 = isset( $_GET['paged1'] ) ? (int) $_GET['paged1'] : 1;
  $paged2 = isset( $_GET['paged2'] ) ? (int) $_GET['paged2'] : 1;
  $product_query = new WP_Query(
    array(
      'posts_per_page' => 1,
      'post_type' => 'product',
      'paged'  => $paged1
    )
  );
  if($product_query->have_posts()) :
?>

  <div>
    <?php
      while($product_query->have_posts()) :
      $product_query->the_post();
    ?>
      <div>
        <a href="<?php the_permalink(); ?>">
          <?php the_title(); ?>
        </a>
      </div>
    <?php
      endwhile;
      echo paginate_links(
        array(
          'format'   => '?paged1=%#%',
          'current'  => $paged1,
          'total'    => $product_query->max_num_pages,
          'add_args' => array( 'paged2' => $paged2 )
        )
      );
      wp_reset_postdata();
    ?>
  </div>

<?php endif; ?>

<?php
  $person_query = new WP_Query(
    array(
      'posts_per_page' => 1,
      'post_type' => 'person',
      'paged'  => $paged2
    )
  );
  if($person_query->have_posts()) :
?>

  <div>
    <?php
      while($person_query->have_posts()) :
      $person_query->the_post();
    ?>
      <div>
        <a href="<?php the_permalink(); ?>">
          <?php the_title(); ?>
        </a>
      </div>
    <?php
      endwhile;
      echo paginate_links(
        array(
          'format'   => '?paged2=%#%',
          'current'  => $paged2,
          'total'    => $person_query->max_num_pages,
          'add_args' => array( 'paged1' => $paged1 )
        )
      );
      wp_reset_postdata();
    ?>
  </div>

<?php endif; ?>

那么在这里您可以如何使用自定义帖子类型实现分页

<?php

  $paged1 = isset( $_GET['paged1'] ) ? (int) $_GET['paged1'] : 1;
  $cat_query = new WP_Query(
    array(
      'paged'          => $paged1,
      'posts_per_page' => 2,
      'post_type' => 'cat'
    )
  );
  if($cat_query->have_posts()) :
?>

  <div>
    <?php
      while($cat_query->have_posts()) :
      $cat_query->the_post();
    ?>
      <div>
        <a href="<?php the_permalink(); ?>">
          <?php the_title(); ?>
        </a>
      </div>
    <?php
      endwhile;

    ?>
  </div>

<?php endif; 
$pag_args1 = array(
    'format'   => '?paged1=%#%',
    'current'  => $paged1,
    'total'    => $cat_query->max_num_pages,
    'add_args' => array( 'paged1' => $paged1 )
);
echo paginate_links( $pag_args1 );
 wp_reset_postdata();
wp_reset_query(); 
?>
<?php
  $cat_query1 = new WP_Query(
    array(
      'paged'          => $paged1,
      'posts_per_page' => 2,
      'post_type' => 'dog'
    )
  );
  if($cat_query1->have_posts()) :
?>

  <div>
    <?php
      while($cat_query1->have_posts()) :
      $cat_query1->the_post();
    ?>
      <div>
        <a href="<?php the_permalink(); ?>">
          <?php the_title(); ?>
        </a>
      </div>
    <?php
      endwhile;

    ?>
  </div>

<?php endif; 

$pag_args2 = array(
    'format'   => '?paged1=%#%',
    'current'  => $paged1,
    'total'    => $cat_query1->max_num_pages,
    'add_args' => array( 'paged1' => $paged1 )
);
echo paginate_links( $pag_args2 );
wp_reset_postdata();
wp_reset_query(); 
?>

希望一切顺利
