如何在会话中传递表单字段值，并在CakePHP中的DIV标签中显示

Question

谢谢，实际上，我有一个表格，带有考试名称，场地，考试日期，价格/课程，考试数量，并添加到购物车提交按钮，以下我有一个<div id="division"></div>。在表单字段中输入详细信息并提交表单后，表单字段值应传递到以下<div id="division"></div>标签。对于表单的每个条目，值应添加到<div id="division"></div>标签中。我想删除我之前添加的项目。我可以使用CakePHP中的会话来进行此操作。例如，在购物车中的购物车中添加物品。

My index.ctp view page
   <table><thead>
          <th>Exam Name</th>
          <th>Venue Name</th>
          <th>Date of Exam</th>
          <!--<th>Documents</th> --> 
          <th>Price / Course</th>  
          <th>Number of Exams</th>
          <th style="display:none">Document</th>  
          <th>Add to Cart</th> 
         </thead>

您的问题非常广泛，并且代码看起来不明显。在CakePHP中，您应该使用表格助手来构建表单（http://book.cakephp.org/3.0/en/views/helpers/form.html）并发布数据，然后在控制器操作中处理该数据并使用会话对象存储数据（http://book.cakephp.org/3.0/en/development/sessions.html#accessing-the-session-object）
