CURD 例子

    public function modify(){

			 $id=$_GET['id'];

			 $m=M('user');

			 $arr=$m->find($id);

			 //var_dump($arr);

			 $this->assign('data',$arr);

		   $this->display();

	   }

modify 方法:

对应的前台模板:

E:\thinkphp\ThinkPHP视频教程7.ThinkPHP 3.1.2 CURD演示 2\thinkphp\Home\Tpl\User\modify.html

<!doctype html>

<html lang="en">

 <head>

   <meta charset="UTF-8">

  <meta name="Generator" content="EditPlus?">

  <meta name="Author" content="">

  <meta name="Keywords" content="">

  <meta name="Description" content="">

  <title>Document</title>

  <script>

    window.onload=function(){

	   //alert ("<{$data.sex}>");

  }

    </script>

 </head>

 <body>

       <form action="/thinkphp/index.php/User/update" method='post'>

	   <input type='hidden' name='id' value="<{$data.id}>">

	  姓名:<input type="text" name='username' value="<{$data.username}>"/><br/>

	   性别:男<input type='radio' name='sex' value='1' checked >女<input type='radio'

	   name='sex' value='0'/><br/>

	   <input type="submit" value="提交修改"/>

	   </form>

 </body>

</html>

modify.html 又调用 /thinkphp/index.php/User/update 方法:

	   public function update(){

			 $id=$_GET['id'];

			 $m=M('user');

			 $data['id']=$_POST['id'];

			 $data['username']=$_POST['username'];

			 $data['sex']=$_POST['sex'];

			 $arr=$m->Save($id);

			 $count=$m->save($data);

			 //success 方法会调回到上一个页面

			  if($count >0){$this->success('数据修改成功','index');}

		   else{$this->error('数据修改失败','index');}

			 //var_dump($arr);

			// $this->assign('data',$arr);

		  // $this->display();

	   }
