至少选中一个复选框时如何将值发布到数据库中

Question

我的带有复选框验证脚本的视图。我希望当我选中一个复选框时，应该存储与其相关的数据。

<form action="<?php echo site_url('need_assesment/insertservice'); ?>" [enter image description here][1]method="post">
        <div class="col-lg-11 col-md-5 col-sm-8 col-xs-9 bhoechie-tab-container">
            <div class="col-lg-2 col-md-3 col-sm-3 col-xs-3 bhoechie-tab-menu">
              <div class="list-group">
                <?php foreach($member_details as $members){?>
                <a href="<?php echo base_url('index.php/need_assesment/req_questions/'.$m_id."/".$members->id);?>" class="list-group-item active text-center">
                  <br/><?php echo $members->member_name; ?>

                </a>
