如何在 wordpress postmeta 表中保存多个复选框?我应该将它们保存为数组吗?表单提交后如何访问它们?以及如何在编辑时显示选定的复选框值?

How Do I save multiple checkboxes in wordpress postmeta table? Should I save them as array? How Do I access them after form submit? And how do I display selected checkbox value while editing??

提交保存代码

<?php 
        //submit code 
          if(isset($_POST['service_name'])  ){
              $data=serialize($_POST['service_name']);

              update_post_meta($postid, 'service_name', $data);
          }
        ?>

编辑代码

<?php 
        //edit code

            $data=get_post_meta($postid, 'service_name');
            //$data=unserialize($data[0]);
            $data=$data[0];
            print_r($data);

        ?> 

        <input type="checkbox" id="architecture" size="80" name="service_name[]"  value="Architecture" <?php if(in_array('Architecture',$data)  ){echo "checked";} ?> >Architecture
