Question

使用wordpress元数据插件并尝试将元数据保存为多维数组（我稍后会讨论的文本中）。

这是我的代码：

function wordpress_metabox() {

 $event_adress = explode('|', get_post_meta($post->ID, '_event_adress', true));
 foreach ($event_id as $key => $id){

  echo '<div class="event">
  <div class="ticket">
  <input type="text" name="_event_adress[]" value="'.$event_adress[$key].'" />
   <input type="text" name="_event_price[]" value="'.$event_price[$key].'" />
  </div><!-- end .ticket -->
  <div class="ticket">
   <input type="text" name="_event_adress[]" value="'.$event_adress[$key].'" />
   <input type="text" name="_event_price[]" value="'.$event_price[$key].'" />
  </div><!-- end .ticket -->
  <input type="button" class="button" id="add_ticket" value="+ Add ticket" />
 </div><!-- end .event -->
 <input type="button" class="button" id="add_event" value="+ Add Event" />';

 }

}

//this is the save function
function wordpress_metabox_save($post_id, $post) {

 // Is the user allowed to edit the post or page?
 if ( !current_user_can( 'edit_post', $post->ID ))
     return $post->ID;

 // OK, we're authenticated: we need to find and save the data
 // We'll put it into an array to make it easier to loop though.

 $event_meta['_event_adress'] = $_POST['_event_adress'];
 $event_meta['_event_id'] = $_POST['_event_id'];

 // Add values of $event_meta as custom fields
 foreach ($event_meta as $key => $value) { // Cycle through the $event_meta array!
     if( $post->post_type == 'revision' ) return; // Don't store custom data twice
     $value = implode('|', (array)$value); // If $value is an array, separate with |

     if(get_post_meta($post->ID, $key, FALSE)) { // If the custom field already has a value
         update_post_meta($post->ID, $key, $value);
     } else { // If the custom field doesn't have a value
        add_post_meta($post->ID, $key, $value);
     }
     if(!$value) delete_post_meta($post->ID, $key); // Delete if blank
 }
}

实际应该是一个foreach循环，但我还没有那么远，这就是为什么我写两次相同的div来说明。有人可以回答我如何在多维数组中保存每张票的地址和价格吗？我不确定是否可以输入例如_event_adress [] []将每个数据存储在嵌套数组中？或者我必须输入第一个键吗？
