我对meta box中的复选框列表类型有问题。这是我的密码meta-box-config.php:

$meta_boxes[] = array(
\'id\'        => \'poker_room_extension\',
\'title\'     => \'Poker Room Options\',
\'pages\'     => array( \'post\', \'page\' ),

\'fields\'    => array(

    array(
        \'name\'      => \'Sistema operativo supportato\',
        \'id\'        => $prefix . \'os_poker_room\',
        \'clone\'     => false,
        \'type\'      => \'checkbox_list\',
        \'options\'   => array(
            \'windows\'     => \'Windows \',
            \'mac\' => \'Mac \',
            \'linux\' => \'Linux \'
        ),
        \'std\'       => false
    )
)
 );

变量omc\\u os\\u poker\\u room相同，这正常吗？如何显示值？omc\\u os\\u poker\\u room是否为阵列？我不明白。

如果我在模板中运行此代码，它将仅显示第一个值（windows，而不是选中的其他值）：

$omc_os_poker_room =  get_post_meta(get_the_ID(), \'omc_os_poker_room\', true);
$conta = count($omc_os_poker_room);

        <?php if ($omc_os_poker_room != \'\') {
            echo \'<p class="omc-info-one"><b>OS: </b>\';
            for($i=0;$i<$conta;$i++) {
            echo $omc_os_poker_room[$i];
            } }?>

我替换了这一行：

$omc_os_poker_room =  get_post_meta(get_the_ID(), \'omc_os_poker_room\', true);

$omc_os_poker_room =  get_post_meta(get_the_ID(), \'omc_os_poker_room\', false);
