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>
