Php Chheckbox表格提交

我很难通过表单发送多个复选框条目

我正在使用kirby CMS和联系人表单插件

这是我的代码，如果有人能解释的话

<fieldset name="check">
    <h2>Project Needs</h2>     
    <ul>
        <li><input id="strategy" type="checkbox" name="needs" value="<?php echo $form->htmlValue('needs') ?> Strategy" checked><label for="strategy">Strategy</label></li>
        <li><input id="ux" type="checkbox" name="needs" value="<?php echo $form->htmlValue('needs') ?> UX"><label for="ux">UX</label></li>
        <li><input id="redesign" type="checkbox" name="needs" value="<?php echo $form->htmlValue('needs') ?> Re-Design"><label for="redesign">Re-Design</label></li>
        <li><input id="responsive" type="checkbox" name="needs" value="<?php echo $form->htmlValue('needs') ?> Responsive Design"><label for="responsive">Responsive Design</label></li>
        <li><input id="cms" type="checkbox" name="needs" value="<?php echo $form->htmlValue('needs') ?> CMS Implementation"><label for="cms">CMS Implementation</label></li>
        <li><input id="unsure" type="checkbox" name="needs" value="<?php echo $form->htmlValue('needs') ?> Unsure"><label for="unsure">Unsure</label></li>
    </ul>
</fieldset>  

项目需求

您是否将此发布到另一个PHP脚本？每个复选框都有“需要”的名称；尝试将它们更改为“需要cms”、“需要ux”，以便您可以使用$\u POST['needs-cms']、$\u POST['needs-ux']访问它们的值。我猜在这种情况下应该是
$form->htmlValue（'needs-cms'），$form->htmlValue（'needs-ux'）
，等等。
将每个复选框的名称更改为唯一名称或“needs[]”。
使用“needs[]”将在一个数组中传输所有复选框$\u POST[“needs”]
我尝试将复选框name=“needs”更改为name=“needs[]”，并尝试更改为我仅通过说出数组来接收电子邮件：（我需要保留所有被调用的名称，因为我希望返回以下结果：ux重新设计响应等
