laravel 框架的路由设置： url: http://www.shanzezhao.com/laraverl/my_laravel/public/index.php/indexs
laravel 框架的数据库设置：config/database.php
1 \'mysql\' => [
2 \'driver\' => \'mysql\', 3 \'host\' => \'localhost\', 4 \'port\' => \'3306\', 5 \'database\' => \'laravel\', 6 \'username\' => \'root\', 7 \'password\' => \'123456\', 8 \'unix_socket\' => \'\', 9 \'charset\' => \'utf8\', 10 \'collation\' => \'utf8_unicode_ci\', 11 \'prefix\' => \'\', 12 \'strict\' => true, 13 \'engine\' => null, 14 ],
laravel 框架的增删改查：：
1 <?php 2 3 4 namespace App\\Http\\Controllers; 5 6 use DB; 7 use App\\Http\\Controllers\\Controller; 8 9 10 class IndexController extends Controller 11 { 12 13 //添加展示 14 public function index() 15 { 16 return view(\'index/index\'); 17 18 } 19 //添加 20 public function add() 21 { 22 23 $name=$_POST[\'uname\']; 24 $pwd=$_POST[\'upwd\']; 25 // print_r($pwd);die; 26 //设置数据表
$re=DB::table(\'text1\')->insert([\'uname\'=>$name,\'upwd\'=>MD5($pwd)]); 27 // print_r($re);die; 28 if($re) 29 { 30 return redirect(\'show\'); 31 } 32 } 33 //数据展示 34 public function show() 35 { 36 $re = DB::table(\'text1\')->get(); 37 // print_r($re);die; 38 return view(\'index/show\',[\'re\'=>$re]); 39 } 40 //删除 41 public function deletes() 42 { 43 $id=$_GET[\'id\']; 44 // print_r($id);die; 45 $re= DB::table(\'text1\') 46 ->where(\'id\',$id) 47 ->delete(); 48 if($re) 49 { 50 return redirect(\'show\'); 51 } 52 53 } 54 //修改页面 55 public function updates() 56 { 57 $id=$_GET[\'id\']; 58 //print_r($id);die; 59 $re = DB::table(\'text1\')->where(\'id\',$id)->first(); 60 // print_r($re);die; 61 return view(\'index/upd\',[\'re\'=>$re]); 62 63 64 } 65 //修改 66 public function upd() 67 { 68 $name=$_POST[\'uname\']; 69 $pwd=$_POST[\'upwd\']; 70 $id=$_POST[\'id\']; 71 $arr=array(\'id\'=>$id,\'uname\'=>$name,\'upwd\'=>$pwd); 72 $re=DB::table(\'text1\') 73 ->where(\'id\',\'=\',$id ) 74 ->update($arr); 75 if($re) 76 { 77 return redirect(\'show\'); 78 } 79 80 81 } 82 83 }
表单和以前学的框架大致还是没有什么区别的
resources/views/index/index.blade.php
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> </head> <body> <form action="add" method="post" > <input type="hidden" name="_token" value="<?php echo csrf_token(); ?>"> <table> <tr> <td>姓名：</td> <td><input type="text" name="uname"></td> </tr> <tr> <td>密码：</td> <td><input type="password" name="upwd"></td> </tr> <tr> <td><input type="submit" value="提交"></td> <td></td> </tr> </table> </form> </body> </html>
show.php
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<center>
<table>
<tr>
<td>姓名</td>
<td>加密密码</td>
<td>设置</td>
</tr>
<?php foreach ($re as $key => $val): ?>
<tr>
<td><?php echo $val->uname; ?></td>
<td><?php echo $val->upwd; ?></td>
<td>
<a href="deletes?id=<?php echo $val->id ?>">删除</a>
<a href="updates?id=<?php echo $val->id ?>">修改</a>
</td>
</tr>
<?php endforeach ?>
</table>
</center>
</body>
</html>
upd.php
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<form action="upd" method="post" >
<input type="hidden" name="_token" value="<?php echo csrf_token(); ?>">
<input type="hidden" name="id" value="<?php echo $re->id ?>">
<table>
<tr>
<td>姓名：</td>
<td><input type="text" name="uname" value="<?php echo $re->uname ?>"></td>
</tr>
<tr>
<td>密码：</td>
<td><input type="password" name="upwd" value="<?php echo $re->upwd ?>"></td>
</tr>
<tr>
<td><input type="submit" value="修改"></td>
<td></td>
</tr>
</table>
</form>
</body>
</html
