(1/1) ErrorException
未定义索引:密码
但是，我已经在UserLoginController.php文件中声明了用户名和密码.
But , I have declared Username and Password in UserLoginController.php file.
如何解决此问题?
这是UserLogin.blade.php(查看文件).
Here is the UserLogin.blade.php ( View file ).
<!DOCTYPE html>
<html>
<head>
</head>
<body">
<form method="post" action="{{ route('UserLogin') }}">
{{ csrf_field() }}
Username : <input type="text" name="username"> <br><br>
Password : <br><input type="password" name="password" class="text"> <br><br>
<input type="submit" name="login" value="Login"> <br>
<small><a href="{{ route('first') }}">Return Home</a></small>
</form>
</center>
</body>
</html>
这是UserLoginController.php(控制器文件).
Here is the UserLoginController.php ( Controller file ).
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\login;
use Illuminate\Support\Facades\Auth;
class UserLoginController extends Controller
{
public function index()
{
return view('UserLogin');
}
public function login(Request $request)
{
$this->validate($request, [
'username' => 'required',
'password' => 'required'
]);
if (Auth::attempt(['username' => $request['username'], 'pw' => $request['password']])) {
return redirect('RegView');
}
return redirect('UserLogin');
}
}
这是login.php(模型文件).
Here is the login.php ( Model file ).
<?php
namespace App;
use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Database\Eloquent\Model;
class login extends Model implements Authenticatable
{
use \Illuminate\Auth\Authenticatable;
}
我已经在Auth.php文件中写了这个
And I have written this in Auth.php file
'providers' => [
'users' => [
'driver' => 'eloquent',
'model' => App\User::class,
],
// 'users' => [
// 'driver' => 'database',
// 'table' => 'users',
// ],
'users' => [
'driver' => 'eloquent',
'model' => App\login::class,
],
这是我创建的路线.
Here is the Routes that I have created.
Route::any('/UserLogin', 'UserLoginController@index')->name('UserLogin');
Route::post('/UserLogin','UserLoginController@login');
这是我的登录表.
Here is my logins table.
推荐答案
首先检查您的模型login在登录数据库模式中是否在字段password中，然后进行以下更改:
first check if your model login has a field password in the login database schema after that change this :
if (Auth::attempt(['username' => $request->get('username'), 'pw' => $request->get('password')])) {
return redirect('RegView');
}
收件人:
if (Auth::attempt(['username' => $request->get('username'), 'password' => $request->get('password')])) {
return redirect('RegView');
}
还转到您的app/Http/Auth/LoginController.php并添加以下内容:
also go to your app/Http/Auth/LoginController.php and add this :
/**
* Get the login username to be used by the controller.
*
* @return string
*/
public function username()
{
return 'username';
}
最后改变这个:
'providers' => [
'users' => [
'driver' => 'eloquent',
'model' => App\User::class,
],
// 'users' => [
// 'driver' => 'database',
// 'table' => 'users',
// ],
'users' => [
'driver' => 'eloquent',
'model' => App\login::class,
],
对此:
'providers' => [
'users' => [
'driver' => 'eloquent',
'model' => App\login::class,
],
检查页面刷新是否存在任何错误:
check if there is any errors if the page refresh :
@if ($errors->any())
<div class="alert alert-danger">
<ul>
@foreach ($errors->all() as $error)
<li>{{ $error }}</li>
@endforeach
</ul>
</div>
@endif
