I have this view page index.blade.php
#section('main')
<h1>All Users</h1>
<p><a href={!! url('users\create') !!}>Add new user</a></p>
#if ($users->count())
<table border="2">
<tr><td>s.n.</td><td>name</td><td>email</td><td>options</td>
#foreach ($users as $user)
<tr>
<td>{{ $user->id }}</td>
<td>{{ $user->name }}</td>
<td>{{ $user->email }}</td>
<td><a href={{ url('users\{id}\edit', $user->id)}}>Edit</a>
<td>
{!! Form::open(array('method' => 'DELETE',
'route' => array('users.destroy', $user->id))) !!}
{!! Form::submit('Delete', array('class' => 'btn btn-danger')) !!}
{!! Form::close() !!}
</td>
</tr>
#endforeach
</table>
#else
There are no users
#endif
#stop
and controller
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\User;
class usercontroller extends Controller
{
public function index()
{
$users=User::all();
return view('users.index', compact('users'));
}
public function create()
{
return View('users.create');
}
public function store()
{
$input = Input::all();
$validation = Validator::make($input, User::$rules);
if ($validation->passes())
{
User::create($input);
return Redirect::route('users.index');
}
return Redirect::route('users.create')
->withInput()
->withErrors($validation)
->with('message', 'There were validation errors.');
}
public function show($id)
{
//
}
public function edit($id)
{
$user = User::find($id);

return Redirect::route('users.show', $id);
}
return Redirect::route('users.edit', $id)

->withErrors($validation)
->with('message', 'There were validation errors.');
}
public function destroy($id)
{
User::find($id)->delete();
return Redirect::route('users.index');
}
}
and
routes.php
Route::resource('users', 'UserController');
but when i enter laravel/public/users it displays the white blank page. same problem with any other routes such as:
Route::get('/users/edit/{id}','UserController#edit');
Route::put('/users/{id}','UserController#update');
Route::delete('/users/{id}','UserController#delete');
the problem occurred when i follow these steps https://laravelcollective.com/docs/5.2/html to use forms.
. earlier the error was 'class form' not found.
the app/User.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use DB;
class User extends BaseModel
{
protected $primarykey='id';
protected $table='users';
protected $fillable=array('name','email','password');
public static $rules = array(
'name' => 'required|min:5',
'email' => 'required|email'
);
}
and basemodel
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use DB;
class BaseModel extends Model {
public function selectQuery($sql_stmt) {
return DB::select($sql_stmt);
}
public function sqlStatement($sql_stmt) {
DB::statement($sql_stmt);
}
}

at first change your controller file name app/Http/Controller/usercontroller.php to app/Http/Controller/UserController.php.then in UserController.php you edit your class name like below:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\User;
class UserController extends Controller
Then make sure that you have a model name app/User.php which contains all the table field and table name.In app/Http/routes.php you set another route
Route::get('users','UserController#index');
then you can enter laravel/public/users

public function jenis(){
return $this->hasMany('App\Jenis');
}
}
Model
> Controller
$profile = Profile::all();
return view('profile/homeprofile',['profile' => $profile]);
Controller
no error
only data does not appear
Check your db migration file. define this in create_tbl_profil_penyedia_table :
Migrate it.
$table->unsignedInteger('id_jenis_penyedia')->unsigned();
$table->foreign('id_jenis_penyedia')->references('id_jenis_penyedia')->on('tbl_jenis_penyedia');
Edit your Jenis model
public function jenis(){
return $this->hasMany('App\Jenis', 'id_jenis_penyedia');
}
According to your controller your view should work like this:
#foreach($profile as $p)
#foreach($p as $a)
{{ $a->jenis->jenis_penyedia }},
#endforeach
#endforeach

Cant store information on DB from Laravel form

I have this application using Laravel and im trying to register some information from the Form Class to my DB through the store method in the controller, but for some reason it throws me some error. I cant even print the request coming from the form, as usual. Can someone point me a possible mistake tht i am making? I am new to Laravel
This is my form on a view called create.blade.php
#extends('layouts.app')
#section('content')
<p><b>Register your house</b></p>
{!! Form::open(['method'=>'post', 'action'=>'AdminHouseController#store']) !!}
{!! Form::text('house_address', null,['placeholder'=>'House Address']) !!}
<input type="hidden" name="house_admin" value="{{Auth::user()->id}}">
{!! Form::number('nflatmates', null, ['placeholder'=>'How many flatmates']) !!}
{!! Form::submit('Register', ['class'=>'ui-btn buttonDefault']) !!}
{!! Form::close() !!}
#stop
This is my controller AdminHouseController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\House;
use App\User;
class AdminHouseController extends Controller
{
public function index(){
}
public function create($role_id){
if($role_id == 1){
return view('admin.house.create');
}else{
return redirect('home');
}
}
public function store(Request $request){
House::create($request->all());
return redirect('home');
}
public function show($id){
}
public function edit($id){
}
public function update(Request $request, $id){
}
public function destroy($id){
}
}
And this is my router file web.php
use App\User;
Route::get('/', function () {
return view('welcome');
});
Auth::routes();
Route::get('/home', 'HomeController#index')->name('home');
Route::get('/house/{role_id}', 'AdminHouseController#create')->name('house');
Route::post('store', [
'uses' => 'AdminHouseController#store'
]);
you might be missing the {{ csrf_field() }} in the form this used to protect the form from tampering

laravel 5 routing error

the error is:
Route [users.destroy,$user->id] not defined. (View:
C:\xampp\htdocs\laravel\resources\views\users\index.blade.php)
in index.blade.php

{!! Form::submit('Delete', array('class' => 'btn btn-danger')) !!}
{!! Form::close() !!}
</td>
</tr>
#endforeach
</table>
#else
There are no users
#endif
#stop
and the controller is:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\User;
class UserController extends Controller
{
public function index()
{
$users=User::all();
return view('users.index', compact('users'));
}
public function create()
{
return View('users.create');
}
public function store()
{
$input = Input::all();
$validation = Validator::make($input, User::$rules);
if ($validation->passes())
{
User::create($input);
return Redirect::route('users.index');
}
return Redirect::route('users.create')
->withInput()
->withErrors($validation)
->with('message', 'There were validation errors.');
}
public function show($id)
{
//
}
public function edit($id)
{
$user = User::find($id);
if (is_null($user))
{
return Redirect::route('users.index');
}
return View('users.edit', compact('user'));
}
public function update($id)
{
$input = Input::all();
$validation = Validator::make($input, User::$rules);
if ($validation->passes())
{
$user = User::find($id);
$user->update($input);
return Redirect::route('users.show', $id);
}
return Redirect::route('users.edit', $id)
->withInput()
->withErrors($validation)
->with('message', 'There were validation errors.');
}
public function destroy($id)
{
User::find($id)->delete();
return Redirect::route('users.index');
}
}
and when i delete the form in view file index.blade.php the white blank page appears. earlier i didnot install html entities and it worked well except for the part of form.
Use this:
'route' => array('users.destroy', $user->id)
Then make sure you have users.destroy route in your routes.php file.

Have you added the error trapping logic to your app/Exceptions/Handler.php file?
Check out http://laravel.com/docs/5.0/eloquent ; specifically where it states:
Retrieving A Model By Primary Key Or Throw An Exception
Sometimes you may wish to throw an exception if a model is not found. To do this, you may use the firstOrFail method:
$model = User::findOrFail(1);
$model = User::where('votes', '>', 100)->firstOrFail();
Doing this will let you catch the exception so you can log and display an error page as necessary. To catch the ModelNotFoundException, add some logic to your app/Exceptions/Handler.php file.
use Illuminate\Database\Eloquent\ModelNotFoundException;
class Handler extends ExceptionHandler {
public function render($request, Exception $e)
{
if ($e instanceof ModelNotFoundException)
{
// Custom logic for model not found...
}
return parent::render($request, $e);
}
}

'MethodNotAllowedHttpException' means that the route that is being hit isnt set up for the http type that has been sent.
So for /signup, you allow a GET request but your form is using POST to send data to it. Make a route that accepts POST to use the relevant controller and method.
Route::post('/signup', 'UserController#postSignup');
Edit:
Ah, I think it may be Route::resource('user', 'UserController') that's causing the problem. Laravel Docs says that ::resource('user', 'UserController') should have restful actions in your controller like UserController#index, UserController#create, UserController#store, etc.
Your controller can be autopopulated with the relevant actions using 'php artisan controller:make UserController' Note: this may delete what you currently have in place
If you're not utilising Route::resource to handle requests though, go ahead and remove it.
