多个查询的一个分页(或如何对一个查询进行分组)

标签: wordpress pagination

我在同一页面中有多个查询,如下所示:

$args_1 = array (
    'category_name' => get_query_var( 'category_name' ),
    'post__in'      => $sticky = get_option( 'sticky_posts' );
    'orderby' => 'date',
    'order' => 'DESC'    
);

$sticky_query = new WP_Query ($args_1);

// loop


$args_2 = array(
    'category_name' => get_query_var( 'category_name' ),
    'post__not_in'  => get_option( 'sticky_posts' ),
    'category__not_in' => array(11114),
    'orderby' => 'date',
    'order' => 'DESC'
);

$query_2 = new WP_Query ($args_2);

// loop



$args_3 = array(
    'category_name' => get_query_var( 'category_name' ),
    'post__not_in'  => get_option( 'sticky_posts' ),
    'category__in' => array(11114),
    'orderby' => 'date',
    'order' => 'DESC'
);


$query_3 = new WP_Query($args_3 );

// loop

我会:

1)将每页的帖子总数限制为15

2)(我不能这样做,我在任何地方搜索过但我没有找到解决方案)使这个“组合”分页工作。现在,这是合乎逻辑的,第二页与第一页相同......

或者解决方案可以是只进行一次查询并对帖子进行分组并改为对组进行排序?

最终解决方案

  1. 如果合并两个查询并且不使用“offset”,则不需要自定义分页,所以我已删除

    $big = 999999999; // need an unlikely integer
    
    echo paginate_links( array(
        'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big  ) ) ),
        'format' => '?paged=%#%',
        'current' => max( 1, get_query_var('paged') ),
        'total' => $the_query->max_num_pages
    ) );
    
  2. 并补充道:

        echo paginate_links(); 
    
    1. 您必须将'order'设置为'post__in'值,以便在单独的查询中保留给帖子的顺序。

    2. 为了避免内存错误(例如“致命错误:允许的内存大小为134217728字节耗尽(试图分配262144字节)”。)由查询中包含许多帖子引起的,您只需要检索post id在查询中。 See here.

    3. 这是最终的代码:

          global $wp_query;
      
      
      
          $paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;
          $post_per_page = 35; // How many post per page - setup as you need
          $nr_of_posts_to_be_analyzed_to_include_only_current_events = 100; // How many post to analyze to include only current events, ie events that are not in category id 11114
      
      
      
          $sticky = get_option( 'sticky_posts' );
      
          // posts in category, limited in number otherwise - if you set '-1' and you have 7.000 posts - you exceed the script time limit execution 
          $category_posts = get_posts(array('category_name' => get_query_var( 'category_name' ), 'posts_per_page' => $nr_of_posts_to_be_analyzed_to_include_only_current_events,'orderby' => 'date', 'order' => 'DESC'));
      
          $category_posts_ids = array();
      
          foreach( $category_posts as $post ) {
      
              $category_posts_ids[]=$post->ID; // Array with posts ID
      
          }
          // var_dump($category_posts_ids);
      
      
         // expired posts in category, limited in number otherwise - if you set '-1' and you have 7.000 posts - you exceed the script time limit execution 
         $expired_posts = get_posts(array('category__and' => array(11114, get_query_var('cat')), 'posts_per_page' => $nr_of_posts_to_be_analyzed_to_include_only_current_events, 'orderby' => 'date', 'order' => 'DESC'));
      
         $expired_posts_ids = array();
      
         foreach( $expired_posts as $post ) {
      
              $expired_posts_ids[]=$post->ID; // Array with posts ID
      
         }
      
      
      
         // first 100 posts in this category per page - the expired posts that are in 100 first posts in this category gives as result an array of not expired posts
         $array_where_to_get_post =  array_diff( $category_posts_ids, $sticky, $expired_posts_ids );
      
      
      
         // 1/3 only the sticky posts
         $stickies_posts_args = array(
          'category_name' => get_query_var( 'category_name' ),
          'post__in'  => get_option( 'sticky_posts' ),
          'orderby' => 'date',
          'order' => 'DESC',
          'posts_per_page' => -1,
          'fields'         => 'ids' // important: to avoid memory exhausted error we retrieve postids only
          );
      
         // 2/3 only the not expired and not sticky posts
         $not_expired_posts_args = array(
          'post__in' => $array_where_to_get_post,
          'orderby' => 'date',
          'order' => 'DESC',
          'posts_per_page' => -1,
          'fields'         => 'ids', // important: to avoid memory exhausted error we retrieve postids only,
          'suppress_filters' => false 
         );
      
         // 3/3 only the expired and not sticky posts
         $expired_posts_args = array(
          'category_name' => get_query_var( 'category_name' ),
          'post__not_in'  => get_option( 'sticky_posts' ), // not sticky posts

          'fields'         => 'ids' // important: to avoid memory exhausted error we retrieve postids only
         );
      
      
        $firstQuery = get_posts($stickies_posts_args);
      
        add_filter('posts_join','join_posts_and_events'); // apply some filter
        add_filter('posts_orderby', 'order_posts'); // apply some filter
        $secondQuery = get_posts($not_expired_posts_args);
        remove_filter('posts_join','join_posts_and_events');
        remove_filter('posts_orderby', 'order_posts');
      
        $thirdQuery = get_posts($expired_posts_args);
      
      
        $mergePosts = array_merge( $firstQuery, $secondQuery, $thirdQuery ); // Merge all queries
      
        $uniquePosts = array_unique($mergePosts); // Create an array with unique posts
      
         // Final query
         $args = array(
          'post_type' => 'any',   
          'post__in' => $uniquePosts,
          'paged' => $paged,
          'orderby' => 'post__in', // order the posts as they are (already ordered)
          'order' => 'DESC',
          'posts_per_page' => $post_per_page,
          'ignore_sticky_posts' => 1 // otherwise it breaks pagination
         );
      
        $wp_query = new WP_Query($args);
      
          if ( $wp_query->have_posts() ) :
      
             while ( $wp_query->have_posts() ) { $wp_query->the_post();
      
         // outputs what you want
      
        endwhile; 
      
        endif;
      
        echo paginate_links(); 
      

答案 1 :(得分:2)

将以下参数添加到每个查询中以进行分页

'paged' => get_query_var('<'page' or something else you defined>')

编辑:嗯,也许这个工作!

$query1 = new WP_Query($args1); // Has above paginate param
$query1Ids = get_all_id_in_query1($query1);

$args2 = array(
    'post__not_in' => $query1Ids,
    // Other param
);
$query2 = new WP_Query($args2); // Have above paginate param
$query2Ids = get_all_id_in_query2($query2);

$args3 = array(
    'post__not_in' => array_merge($query1Ids, $query2Ids),
    // Other param, also have paginate param
);
$query3 = new WP_Query($args3);

循环每个查询并显示您的帖子。

答案 2 :(得分:1)

尝试下面这个,我合并了两个查询(帖子和页面)。为我工作 - 用分页显示所有帖子/页面。

<?php 

$paged = get_query_var('paged') ? get_query_var('paged') : 1;
$post_per_page = 5; // How many post per page - setup as you need

$firstQuery = new WP_Query('post_type=post'); // First query - you should change args
$secondQuery = new WP_Query('post_type=page'); // Second query - you should change args


$post_ids = array_merge( $firstQuery, $secondQuery ); // Merge all queries

$query = new WP_Query(
    array(
        'post_type'      => array('post', 'page'), // You should change post types as you need
        'post__in'       => $post_ids, 
        'paged'          => $paged,
        'orderby'        => 'date', 
        'order'          => 'DESC',
        'posts_per_page' => $post_per_page
    )
);

$totalPosts = $firstQuery->post_count + $secondQuery->post_count; // Count posts


if( $query->have_posts() ):

    while( $query->have_posts() ): $query->the_post();

        echo the_title()."</br>"; // Content

    endwhile; 

    wp_reset_query();

endif;


$big = 999999999; // need an unlikely integer

echo paginate_links( array(
    'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
    'format' => '?paged=%#%',
    'current' => max( 1, get_query_var('paged') ),
    'total' => $totalPosts / $post_per_page, // Total pages
) );

?>

新解决方案 - 编辑

只需调整第一个和第二个查询

<?php 

global $wp_query;

$paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;
$post_per_page = 5; // How many post per page - setup as you need

// First query
$firstQuery = get_posts(array(
    'posts_per_page' => -1,
    'category_name' => get_query_var( 'category_name' ),
    'post__in'      => $sticky = get_option( 'sticky_posts' ) 
));

// Second query 
$secondQuery = get_posts(array(
    'posts_per_page' => -1,
    'category_name' => get_query_var( 'category_name' ),
    'post__not_in'  => get_option( 'sticky_posts' ),
));


$mergePosts = array_merge( $firstQuery, $secondQuery ); // Merge all queries

$postIds = array();

foreach( $mergePosts as $post ) {

    $postIds[]=$post->ID; // Array with posts ID

}

$uniquePosts = array_unique($postIds); // Create an array with unigue posts


// Final query
$args = array(
'post_type' => 'any',   
'post__in' => $uniquePosts,
'paged' => $paged,
'orderby' => 'date',
'order' => 'DESC',
'posts_per_page' => $post_per_page,
);


$the_query = new WP_Query($args);

if( $the_query->have_posts() ):

    while( $the_query->have_posts() ): $the_query->the_post();

        echo the_title()."</br>"; // Content

    endwhile; 

    wp_reset_query();

endif;

$big = 999999999; // need an unlikely integer

echo paginate_links( array(
    'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
    'format' => '?paged=%#%',
    'current' => max( 1, get_query_var('paged') ),
    'total' => $the_query->max_num_pages
) );
