一、控制器代码
<?php
namespace App\Http\Controllers;
use Illuminate\Support\Facades\DB;class CurdController extends Controller
{
public function index()
{
return view('curd/add');
}
public function add()
{
$data = $_POST;
$res = DB::table('customer')->insert([
'bh'=>$data['bh'],
'uname'=>$data['uname'],
'charge'=>$data['charge'],
'tel'=>$data['tel'],
'content'=>$data['content']
]);
if($res)
{
return redirect('curd/show');
}
}
public function show()
{
$data = DB::table('customer')->get();
return view('curd/show',['data'=>$data]);
}
public function del()
{
$id = $_GET['id'];
$res = DB::table('customer')->where('id',$id)->delete();
if($res)
{
return redirect('curd/show');
}
}
public function up()
{
$id = $_GET['id'];
$data = DB::table('customer')->where('id',$id)->first();
return view('curd/upda',['data'=>$data]);
}
public function upda()
{
$data = $_POST;
$id = $_POST['id'];
unset($data['_token']);
$res = DB::table('customer')->where('id','=',$id)->update($data);
if($res)
{
return redirect('curd/show');
}
}
}
二、视图代码
（1）添加页面
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>添加</title>
</head>
<body>
<form action="add" method="post">
<input type="hidden" name="_token" value="<?php echo csrf_token(); ?>">
<table border="1">
<tr>
<td>编号</td>
<td><input type="text" name="bh"></td>
</tr>
<tr>
<td>客户名称</td>
<td><input type="text" name="uname"></td>
</tr>
<tr>
<td>负责人</td>
<td><input type="text" name="charge"></td>
</tr>
<tr>
<td>公司电话</td>
<td><input type="text" name="tel"></td>
</tr>
<tr>
<td>描述</td>
<td><input type="text" name="content"></td>
</tr>
<tr>
<td><input type="submit" value="提交"></td>
<td></td>
</tr>
</table>
</form>
</body>
</html>
（2）展示页面
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>展示页面</title>
</head>
<body>
<table border="1">
<tr>
<th>编号</th>
<th>姓名</th>
<th>负责人</th>
<th>电话</th>
<th>描述</th>
<th>操作</th>
</tr>
<?php
foreach ($data as $k=>$v)
{
?>
<tr>
<td><?php echo $v->bh; ?></td>
<td><?php echo $v->uname; ?></td>
<td><?php echo $v->charge; ?></td>
<td><?php echo $v->tel; ?></td>
<td><?php echo $v->content; ?></td>
<td>
<a href="del?id=<?php echo $v->id; ?>">删除</a> |
<a href="up?id=<?php echo $v->id; ?>">修改</a>
</td>
</tr>
<?php } ?></table>
</body>
</html>
（3）修改的默认页面
<form action="upda" method="post">
<input type="hidden" name="_token" value="<?php echo csrf_token(); ?>">
<input type="hidden" name="id" value="<?php echo $data->id; ?>">
<table border="1">
<tr>
<td>编号</td>
<td><input type="text" name="bh" value="<?php echo $data->bh; ?>"></td>
</tr>
<tr>
<td>客户名称</td>
<td><input type="text" name="uname" value="<?php echo $data->uname; ?>"></td>
</tr>
<tr>
<td>负责人</td>
<td><input type="text" name="charge" value="<?php echo $data->charge; ?>"></td>
</tr>
<tr>
<td>公司电话</td>
<td><input type="text" name="tel" value="<?php echo $data->tel; ?>"></td>
</tr>
<tr>
<td>描述</td>
<td><input type="text" name="content" value="<?php echo $data->content; ?>"></td>
</tr>
<tr>
<td><input type="submit" value="修改"></td>
<td></td>
</tr>
</table>
</form>
