留言板的实现是基于前端绑定表单，下面给出直接的代码步骤，用于快速实现。
第一步，开启前端绑定表单的插件 couch/addons/kfunctions.php
通常开启三个：前端表单绑定，会话，邮件发送
require_once( K_COUCH_DIR.'addons/data-bound-form/data-bound-form.php' ); require_once( K_COUCH_DIR.'addons/cart/session.php' ); require_once( K_COUCH_DIR.'addons/phpmailer/phpmailer.php' );
第二步：新建msg.php，创建后台留言板字段
<?php require_once( 'couch/cms.php' ); ?>
<cms:template title="在线留言" clonable='1' order='90'>
<cms:editable type='text' label='姓名' name='msg_name' required='1' order='5'/>
<cms:editable type='text' label='地址' name='msg_address' required='1' order='10'/>
<cms:editable type='text' label='电话' name='msg_tel' required='1' order='15'/>
<cms:editable type='text' label='邮箱' name='msg_email' required='1' order='20'/>
<cms:editable type='textarea' label='留言信息' name='msg_content' height='120' required='1' order='25'/>
<cms:config_list_view orderby='weight' order='asc' searchable='1'>
<cms:field 'k_selector_checkbox' />
<cms:field 'msg_name' header='姓名' class='w100'/>
<cms:field 'msg_tel' header='电话' />
<cms:field 'msg_email' header='邮箱' />
<cms:field 'msg_address' header='地址' />
<cms:field 'msg_content' header='留言信息' />
<cms:field 'k_page_date' header='发布时间' />
<cms:field 'k_up_down' header='排序'/>
<cms:field 'k_actions' header='操作'/>
</cms:config_list_view>
<cms:style>
.w100{
width: 100px;
}
</cms:style>
</cms:template>
<?php COUCH::invoke(); ?>
第三步：在任意其他页面创建提交表单：
<cms:set submit_success="<cms:get_flash 'submit_success' />" />
<cms:if submit_success>
<script type="text/javascript">
alert('您的留言发布成功!');
</script>
</cms:if>
<div class="contact_form">
<h2><cms:show contact_msg_title /></h2>
<cms:form masterpage='msg.php' mode='create' enctype='multipart/form-data' method='post' anchor='0' id="contact_form" class="form_wrapper">
<cms:if k_success>
<!-- email submitted data -->
<cms:send_mail from='shjdkj2023@163.com' to='contact@tex-construction.com' reply_to=frm_email subject='Contact Form tex-construction.com'>
以下是您网站的客户留言:
姓名: <cms:show frm_msg_name />,
地址: <cms:show frm_msg_address />,
邮箱: <cms:show frm_msg_email />,
电话: <cms:show frm_msg_tel />
留言: <cms:show frm_msg_content />
</cms:send_mail>
<!-- email submitted data -->
<cms:db_persist_form _invalidate_cache='0' _auto_title='1' />
<cms:set_flash name='submit_success' value='1' />
<cms:redirect k_page_link />
</cms:if>
<div uk-grid class="uk-grid-small">

</cms:if>

<script type="text/javascript">
$(document).ready(function(){
$("#contact_form").submit(function(){

if(!$('#f_msg_name').val()){
alert("请填写姓名");
return false;
