如何通过查询在前端显示CPT元

我在网站上使用两种自定义帖子类型:团队联盟。我正在为CPT联赛创建一个页面模板,该模板将显示团队所有“团队”帖子中的元数据,其元值与联赛职位类型的名称相匹配。该查询将通过CPT“团队”查找元值“ team_league”。 “ team_league”中的值将与“ league”类型的职位ID之一匹配。然后,我想在“联赛”页面上打印每个匹配的“团队”以及团队帖子中的一些元数据。

如果我仅打印带有查询中找到的帖子名称的简单邮件,则可以成功完成此操作。下面的示例成功查询并打印每个“团队”的职位名称,并带有与“联赛”标题匹配的元值。但是,我需要更复杂的东西。我想从“团队”帖子中提取元数据,并打印一个包含“团队” CPT名称的表格。

有效的简化查询:

if ( $the_query->have_posts() ) {
  echo '<ul>';
  while ( $the_query->have_posts() ) {
    $the_query->the_post();
    echo '<li>' . get_the_title() . '</li>';
  }
  echo '</ul>';

所需查询当前不起作用:

<?php
/*
Template Name: League Layout
Template Post Type: league
*/

$leaguename = get_the_ID();

$args = array(
    'meta_key' => 'team_league',
    'meta_value' => $leaguename,
    'post_type' => 'team',
    'post_status' => 'any',
    'posts_per_page' => -1
);

$the_query = new WP_Query( $args );

// The Loop
if ( $the_query->have_posts() ) {

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

    //Get the team data
    $post_status = get_post_status();
    $team_name = get_the_title();
    $captain_id = get_post_meta(get_the_ID(), 'captain_user_id', true);
    $team_captain = get_user_by( 'ID', $captain_id );
    $team_league = get_post(get_post_meta(get_the_ID(), 'team_league', true));
    $team_players = get_post_meta(get_the_ID(), 'team_players_emails', true);
    $team_paid = get_post_meta(get_the_ID(), 'current_paid_amount', true);
    $team_fee = get_post_meta(get_the_ID(), 'payment_product_price', true);
    $team_balance = round( $team_fee - $team_paid , 2);

   echo '<p>Team Captain: <b>' . $team_captain->first_name . ' ' . $team_captain->last_name; . '</b></p>';
   echo '<p>Team Balance: <b>$' . $team_balance; . '</b></p>';
   echo '<table>';
   echo '<tr>';
   echo '<th>Team Roster</th>';
   echo '</tr>';

   $users_confirmed = 0;
    foreach ($team_players as $team_player) { 
        $user = get_user_by( 'email', $team_player['email'] );
        if( $user ){
            if( !$user->first_name && !$user->last_name ){
                continue;
            }
            echo sprintf( "<tr><td>%s</td></tr>", $user->first_name . ' ' . $user->last_name );
            $users_confirmed++;
        }
    }
    if( 0 == $users_confirmed ){
        echo sprintf( "<tr><td>%s</td></tr>", "No confirmed players for this team" );
    }
    echo '</table>';  
  }
} 

else {
  echo '<p>No Teams in this league</p>';
}
/* Restore original Post Data */
wp_reset_postdata();

用于您的查询Arg。尝试这样的事情:

$args = array (
    'post_type' => 'team',
    'posts_per_page' => -1,
    'meta_query'  => array(
       'relation' => 'AND',
           array(
            'key'     => 'team_league',
            'value'   => $leaguename,
           ),
    ),
);

我认为'post_status' => 'any'无效。这也使用正确的元查询格式。

作为参考,下面的解决方案可以实现上述目标。主要变化是args,我必须在其中包含CPT的自定义帖子状态:

$leagueid = get_the_ID();

$args = array(
  'post_type'      => 'team',
  'posts_per_page' => - 1,
  'post_status' => array( 'mssl-completed', 'mssl-pending', 'publish' ),
  'meta_query' => array(
     array(
        'key'   => 'team_league',
        'value' => "$leagueid",
     ),
   ),
 );

从这里,我能够将从帖子元获取的信息写到我的自定义页面模板中。
