在问之前，让我告诉你两件事<我知道这对某人来说很东东，但对我来说很难
2）我在创建WordPress模板时遇到了这个问题。这就是我在这里发帖的原因
问题：当我打印以下代码时

<?php 

          $home_starting_player_names = rwmb_meta( \'pb_home_starting_player_options\', array( \'multiple\' => true ) ); ?>

          <?php 
           foreach ( $home_starting_player_names as $home_starting_player ){?>
            <li role="presentation">
            <aside class="starting-player-image"><?php  echo get_the_post_thumbnail($home_starting_player); ?></aside>
            <aside class="starting-player-name"><?php  echo get_the_title($home_starting_player); ?></aside>
           <aside class="starting-player-number"><?php $var_dumps = get_post_meta($home_starting_player); 

           print_r ($var_dumps);

           ?></aside>
       <?php } 
        ?>

它的输出如下（我在这里只写了一个）：

Array ( 
[_edit_last] => Array ( [0] => 1 )
 [_edit_lock] => Array ( [0] => 1477596212:1 )
 [pb_squad_number] => Array ( [0] => 10 ) 
[pb_player_date_birth] => Array ( [0] => 2016-09-02 )
)

现在我想显示这个键的值[pb_squad_number].我是说10个。请帮我查一下密码。

echo get_post_meta( $home_starting_player, \'pb_squad_number\', true );
