Laravel表单验证仅在按回按钮时有效

我正在使用Laravel 4.2。在提交表单时,我的问题发生在表单验证期间将会失败的数据(短传,无效的电子邮件等)。

我的表格在/注册。当我提交包含无效数据的表单时,页面变为空白(白色),并且没有数据输入到数据库中。验证错误仅在我点击浏览器中的后退按钮后显示。

如果我输入有效数据,表单会正确提交并向数据库添加数据,并将用户重定向到/ account。

非常感谢任何帮助。我觉得这是一个很小的东西,我正在俯视,它正在踢我的屁股。

这是我的代码......

user.php的

use Illuminate\Auth\UserTrait;
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableTrait;
use Illuminate\Auth\Reminders\RemindableInterface;

class User extends BaseModel implements UserInterface, RemindableInterface {

    use UserTrait, RemindableTrait;

    /**
     * The database table used by the model.
     *
     * @var string
     */
    protected $table = 'users';

    /** Protect from mass-assignment **/
    protected $fillable = array('username', 'email', 'password', 'password_confirmation');

    /**
     * The attributes excluded from the model's JSON form.
     *
     * @var array
     */
    protected $hidden = array('password', 'remember_token');

    public static $rules = array(
        'username'=>'required|unique:users,username|alpha_dash|min:4',
        'password'=>'required|between:8,32|confirmed',
        'password_confirmation'=>'required|between:8,32',
        'email'=>'required|email|unique:users,email'
    );

}

UsersController.php

class UsersController extends BaseController {

    public function getNew() {
        return View::make('users.new')
            ->with('title', 'Create An Account');
    }   

    public function postCreate() {
        $validation = User::Validate(Input::all());

        if ($validation->passes()) {
            User::create(array(
                'username'=>Input::get('username'),
                'password'=>Hash::make(Input::get('password')),
                'email'=>Input::get('email')
            ));

            return Redirect::to('account')->with('message', 'Welcome! Your account has been created.');
        } else {
            Redirect::to('register')->withErrors($validation)->withInput();
        }
    }
}

routes.php文件

Route::get('register', array('as'=>'register', 'uses'=>'UsersController@getNew'));

Route::post('register', array('before'=>'csrf', 'uses'=>'UsersController@postCreate'));

new.blade.php

    @if($errors->has())
        <p>The following errors have occured:</p>

        <ul id="form-errors">
            {{ $errors->first('username', '<li>:message</li>') }}
            {{ $errors->first('password', '<li>:message</li>') }}
            {{ $errors->first('password_confirmation', '<li>:message</li>') }}
            {{ $errors->first('email', '<li>:message</li>') }}
        </ul>   
    @endif

    {{ Form::open(array('action'=>'register')) }}

    <p>
        {{ Form::label('username', 'Username') }}<br />
        {{ Form::text('username', Input::old('username')) }}
    </p>

    <p>
        {{ Form::label('email', 'Email Address') }}<br />
        {{ Form::text('email', Input::old('email')) }}
    </p>

    <p>
        {{ Form::label('password', 'Password') }}<br />
        {{ Form::password('password') }}
    </p>

    <p>
        {{ Form::label('password_confirmation', 'Confirm Password') }}<br />
        {{ Form::password('password_confirmation') }}
    </p>

    <p>
        {{ Form::submit('Register') }}
    </p>

    {{ Form::close() }}

basemodel.php

class BaseModel extends Eloquent {

    public static function validate($data) {
        return Validator::make($data, static::$rules);
    }
}

UsersController::postCreate()功能中,您未在Redirect::to()中返回else{},因此不会将响应发送回用户。控制器正在执行而不返回任何内容,因此您将留下空白页。

Redirect::to('register')->withErrors($validation)->withInput();

需要成为

return Redirect::to('register')->withErrors($validation)->withInput();
