php - 我如何知道以表单传递的值或数组

Question

我遇到了这个问题，但我不知道如何解决。我有一个与数据库交互的项目，我制作了一个用于交互的 CRUD html 表，这意味着我在相关数据库中有 15 个表，我想要插入、删除和编辑记录，所以这是我的代码。我的问题是:我如何知道何时将这些值插入到该表中，以将其插入到数据库中的同一个表中，我真的不知道。

这是我的 Controller :

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

类 Main 扩展 CI_Controller {

Answer 1

是否也发送数据类型？

...
case 'case1':
 $data['table'] = $result..
 $data['table_type'] = 'case1';
break;
case 'case2':
 $data['table'] = $result..
 $data['table_type'] = 'case2';
break;
...

然后，您可以在 View 中将 table_type 变量放在提交按钮上:

<input type="submit" name="<?=$table_type;?>" value="update">

或隐藏区域

<input type="hidden" name="<?=$table_type;?>" value="TRUE">

然后在您接收POST数据的 Controller 上，您可以通过以下方式验证它:

if($this->input->post('case1'))
{
  //for case 1
  //insert/update to case1 table
}elseif($this->input->post('case2'){
  //for case 2
  //insert/update to case2 table
}else{
 //default
}

这只是一个简单的，您可以添加更多安全性或使 POST 值的检查更加动态。
