Question

我尝试合并两种自定义帖子类型：1）CPT =事件2）CPT =位置，在同一个foreach循环中。

e.g。

<?php
  $events = get_posts( array( post_type => event));
  $locations = get_posts( array( post_type => location));
  foreach($events as $event ) {
    foreach($locations as $location ) {
      echo $event->post_title;
      echo $location->post_title;
    }
  }
?>

然而，这只会复制每个帖子标题。我也尝试过以下但是它没有用。

<?php
  foreach($events as $index => $event ) {
    $event->post_title;
    $event->post_title[$index];
  }

Answer 1

我不确定你想要什么作为输出。这应该给你一个所有标题的列表：

foreach($events as $event ) {
  $titles[]=$event->post_title;
}
foreach($locations as $location ) {
  $titles[]=$location->post_title;
}
echo '<ul>';
foreach($titles as $title ) {
  echo '<li>'.$title.'</li>';
}
echo '</ul>';

Answer 2

你应该做的第一件事是切换到使用WP_Query而不是get_posts，你可以做以下快速脏的例子：

// The Query args
$args = array(
    'post_type' => array( 'event', 'location' )
);

// The Query
$the_query = new WP_Query( $args );

// The Loop
if ( $the_query->have_posts() ) {
    echo '<ul>';

   while( $the_query->have_posts() ){
       $post = $the_query->the_post();
       echo '<li>' . get_the_title() . '<li>';
   }

    echo '</ul>';
}

我想我找到了你需要的东西：

$args = array(
  'post_type' => 'event'
);

/* Get events */
$events = get_posts( $args );

foreach($events as $event ) {
  echo '<article><h2>';
  $event->post_title;
  echo '<span>';

  /*get location of event*/
  $args2 = array(
    'post_type' => 'location',
    'meta_key' => '_location_ID', 
    'meta_value' => get_post_meta($event->ID,'_location_ID')
  );
  $locations = get_posts( $args2 );
  foreach($locations as $location ) {
    echo $location->post_title;
  }
  echo '</span></h2></article>';
}

在单个foreach循环中组合2个自定义帖子类型
