问题描述

如何从 object(WP_Query) 获取 $value 数组值?

post_content、ID、页面名称、类别等.

这是我的代码:

<预><代码>全球 $post;$args = 数组('post_type' =>'历史'，'订单' =>'ASC');$master = [];$post_query = new WP_Query($args);如果 ($post_query->have_posts() ) {而 ($post_query->have_posts()) {$post_query->the_post();/* 获取发布日期 */$year = get_the_date('Y');$mon = get_the_date('M');$master[$year][$mon][] = $post_query;}foreach ($master as $masterkey => $mastervalue) {回声<p>";回声主密钥:".$万能钥匙.<br>";foreach($mastervalue as $key => $value) {回声键:".$key .<br>";回声值:".$价值.<br>";}回声</p>";}}wp_reset_postdata();

var_dump for $value 数组:

array(1) { [0]=>object(WP_Query)#2459 (51) { [查询"]=>array(2) { [post_type"]=>string(7) 历史"；[订单"]=>字符串(3)ASC"；} [query_vars"]=>数组(63){[post_type"]=>string(7) 历史"；[订单"]=>字符串(3)ASC"；[错误"]=>字符串(0)"[m"]=>字符串(0)"[p"]=>int(0) [post_parent"]=>字符串(0)"[子帖子"]=>字符串(0)"[subpost_id"]=>字符串(0)"[附件"]=>字符串(0)"[attachment_id"]=>int(0) [名称"]=>字符串(0)"[页面名称"]=>字符串(0)"[page_id"]=>int(0) [第二个"]=>字符串(0)"[分钟"]=>字符串(0)"[小时"]=>字符串(0)"[天"]=>int(0) [monthnum"]=>int(0) [年"]=>int(0) [w"]=>int(0) [category_name"]=>字符串(0)"[标签"]=>字符串(0)"[猫"]=>字符串(0)"[tag_id"]=>字符串(0)"[作者"]=>字符串(0)"[作者姓名"]=>字符串(0)"[饲料"]=>字符串(0)"[tb"]=>字符串(0)"[分页"]=>int(0) [meta_key"]=>字符串(0)"[元值"]=>字符串(0)"[预览"]=>字符串(0)"[s"]=>字符串(0)"[句子"]=>字符串(0)"[标题"]=>字符串(0)"[字段"]=>字符串(0)"[menu_order"]=>字符串(0)"[嵌入"]=>字符串(0)"[category__in"]=>array(0) { } [category__not_in"]=>array(0) { } [category__and"]=>array(0) { } [post__in"]=>array(0) { } [post__not_in"]=>array(0) { } [post_name__in"]=>array(0) { } [tag__in"]=>array(0) { } [tag__not_in"]=>array(0) { } [tag__and"]=>array(0) { } [tag_slug__in"]=>array(0) { } [tag_slug__and"]=>array(0) { } [post_parent__in"]=>array(0) { } [post_parent__not_in"]=>array(0) { } [author__in"]=>array(0) { } [author__not_in"]=>array(0) { } [ignore_sticky_posts"]=>bool(false) [suppress_filters"]=>bool(false) [cache_results"]=>bool(true) [update_post_term_cache"]=>bool(true) [lazy_load_term_meta"]=>bool(true) [update_post_meta_cache"]=>bool(true) [posts_per_page"]=>int(10) [nopaging"]=>bool(false) [comments_per_page"]=>字符串(2)50"[no_found_rows"]=>bool(false) } [tax_query"]=>object(WP_Tax_Query)#2465 (6) { [查询"]=>数组(0){}[关系"]=>字符串(3)与"[table_aliases":受保护]=>array(0) { } [queried_terms"]=>array(0) { } [primary_table"]=>string(11) "pkctU_posts";[primary_id_column"]=>字符串(2)ID"} ["meta_query"]=>对象(WP_Meta_Query)#2452(9){ [查询"]=>数组(0){}[关系"]=>NULL [meta_table"]=>NULL [meta_id_column"]=>NULL [primary_table"]=>NULL [primary_id_column"]=>NULL [table_aliases":protected]=>数组(0){}[子句":受保护]=>数组(0){}[has_or_relation":受保护]=>bool(false) } [date_query"]=>bool(false) [请求"]=>string(295) "SELECT SQL_CALC_FOUND_ROWS pkctU_posts.ID FROM pkctU_posts WHERE 1=1 AND pkctU_posts.post_type = 'history' AND (pkctU_posts.post_status = 'publish' OR pkctU_posts.post_status ='OR pkctU_posts.post_status ='dp-rewrite-republish') ORDER BY pkctU_posts.post_date ASC LIMIT 0, 10"[帖子"]=>数组(8) { [0]=>object(WP_Post)#2458 (24) { [ID"]=>int(3786) [post_author"]=>字符串(1)1"[post_date"]=>字符串(19)2016-01-24 18:34:38"[post_date_gmt"]=>字符串(19)2016-01-24 15:34:38"[post_content"]=>字符串(1937)"在 vero eos et accusam et justo duo dolores et ea rebum.Stet clita kasd gubergren，无海 takimata sanctus est Lorem ipsum dolor 坐 amet.Lorem ipsum dolor sat amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut Labore et dolore magna aliquyam erat, sed diam voluptua.

解决方案

如果此问题与 你的这个问题，你需要以这种格式的每篇文章的标题Year >月 >每个帖子的标题，那么你可以使用以下代码:

$posts = get_posts(array('post_type' =>'历史'，'posts_per_page' =>-1,'orderby' =>'日期'));$master = [];foreach ($posts as $post) {setup_postdata($post);$time = strtotime($post->post_date);$year = date('Y', $time);$mon = date('F', $time);$master[$year][$mon][] = $post->post_title;}wp_reset_postdata();foreach ((array)$master as $yearly => $yvalue) {回声 $yearly .":<br>>回声<ul>";foreach ($yvalue as $monthly => $mvalue) {echo "<li>".$每月.:</li>";回声<ul>";foreach ($mvalue as $post_title_k => $post_title_v) {echo "<li>".$post_title_v .</li>";}echo "</ul>";}echo "</ul>";}

请注意，我使用了 post 对象 中的 post_title.这将返回以下输出:

2021:一月:1.帖子标题2.帖子标题行进:3.帖子标题2020:可能:4.帖子标题

当您使用 get_posts 时，它将返回 post 对象.每个对象包括以下内容:

WP_Post 对象([ID] =>[post_author] =>[post_date] =>[post_date_gmt] =>[post_content] =>[post_title] =>[post_excerpt] =>[post_status] =>[评论状态] =>[ping_status] =>[post_password] =>[post_name] =>[to_ping] =>[ping] =>[后修改] =>[post_modified_gmt] =>[post_content_filtered] =>[post_parent] =>[指南] =>[menu_order] =>[post_type] =>[post_mime_type] =>[评论计数] =>[过滤器] =>)

在上面的代码中，我在这一行中访问了 $post->post_title $master[$year][$mon][] = $post->post_title.

How can I get $value array values from object(WP_Query)?

post_content, ID, pagename, category etc..

Here is my code:


    global $post;
    
    $args = array(
        'post_type' => 'history',
        'order'     => 'ASC'
    );
    
    $master = [];
        
    $post_query = new WP_Query($args);
    
    if ($post_query->have_posts() ) {
                
        while ($post_query->have_posts()) {
                
            $post_query->the_post();
            
            /* Get Post Date */
            $year = get_the_date( 'Y' );
            $mon = get_the_date( 'M' );
                
            $master[$year][$mon][] = $post_query;
            
        }
        
        foreach ($master as $masterkey => $mastervalue) {
            echo "<p>";

            echo "masterkey: ".  $masterkey . "<br>";

            foreach($mastervalue as $key => $value) {
                echo "key: " . $key . "<br>";
                echo "value: " . $value . "<br>";
                                        
            }
            
            echo "</p>";
        }
        
    }

wp_reset_postdata();

var_dump for $value array:

解决方案

If this question is related to this question of yours, and you need the title of each post in this format Year > Months > Title of each post, then you could use the following code:

$posts = get_posts(array(
  'post_type' => 'history',
  'posts_per_page' => -1,
  'orderby'   => 'date'
));

$master = [];

foreach ($posts as $post) {
  setup_postdata($post);

  $time = strtotime($post->post_date);
  $year = date('Y', $time);
  $mon = date('F', $time);

  $master[$year][$mon][] = $post->post_title;
}

wp_reset_postdata();


foreach ((array)$master as $yearly => $yvalue) {
  echo $yearly . ": <br>";
  echo "<ul>";
  foreach ($yvalue as $monthly => $mvalue) {
    echo "<li>" . $monthly . ": </li>";
    echo "<ul>";
    foreach ($mvalue as $post_title_k => $post_title_v) {
      echo "<li>" . $post_title_v . "</li>";
    }
    echo "</ul>";
  }
  echo "</ul>";
}

Notice that i used post_title from the post object. Which will return the following output:

2021:
  January:
    1.Post Title
    2.Post Title
  March:
    3.Post Title

2020:
  May:
    4.Post Title

When you use get_posts it will return post objects. Each object includes the followings:

WP_Post Object
(
    [ID] =>
    [post_author] =>
    [post_date] => 
    [post_date_gmt] => 
    [post_content] => 
    [post_title] => 
    [post_excerpt] => 
    [post_status] =>
    [comment_status] =>
    [ping_status] => 
    [post_password] => 
    [post_name] =>
    [to_ping] => 
    [pinged] => 
    [post_modified] => 
    [post_modified_gmt] =>
    [post_content_filtered] => 
    [post_parent] => 
    [guid] => 
    [menu_order] =>
    [post_type] =>
    [post_mime_type] => 
    [comment_count] =>
    [filter] =>
)

In the code above i accessed $post->post_title in this line $master[$year][$mon][] = $post->post_title.
