将表单数据和变量（ID）传递给控制器​​函数codeigniter

Question

我想将变量（id）和表单数据传递给控制器​​函数。代码如下：

<form action = "index.php/my_controller/my_function" method = "POST">

   <input name = "comment" type = "text" size = "8">
   <input type = "submit" value = "save">
</form>

  <?php
     my_function($id){
                      // get the text
                      // get the id 
                      //save id and text
                     }  
  ?>

当我尝试

时

`action = "index.php/my_controller/my_function/<?php echo record['ID']?>"`

其中$ record ['id']给我id，URL显示id，但是我如何将它传递给控制器​​文件中的my_function（$ id）。

尝试使用隐藏字段

<form action = "index.php/my_controller/my_function" method = "POST">
   <input name = "id" type = "hidden" value="<?php echo $id; ?>">
   <input name = "comment" type = "text" size = "8">
   <input type = "submit" value = "save">
</form>
