在我的函数中，我正在用自定义字段注册多个元数据库。例如，单个metabox数组如下所示：

在函数中。php

$meta_boxes[] = array(
    \'id\' => \'general_info\',
    \'title\' => \'General Information\',
    \'pages\' => array(\'post\', \'page\', \'link\'), // multiple post types, accept custom post types
    \'context\' => \'normal\', // normal, advanced, side (optional)
    \'priority\' => \'high\', // high, low (optional)
    \'fields\' => array(
        array(
            \'name\' => \'Asking Price\',
            \'id\' => $prefix . \'asking_price\',
            \'type\' => \'text\',
            \'std\' => \'\'
        ),
        array(
            \'name\' => \'Currency\',
            \'id\' => $prefix . \'currency\',
            \'type\' => \'text\',
            \'std\' => \'USD\'
        ),
        array(
            \'name\' => \'Salesman\',
            \'id\' => $prefix . \'salesman\',
            \'type\' => \'text\',
            \'std\' => \'Your Name\'
        )
    )
);

在我的主题中，如何从metabox获取所有字段名（甚至可能的值）general_info ? 我试图分别从每个元数据库中检索数据。
