NOTE: this is for an endpoint. not for a form request.
let's say I have middleware named Inputs which has this code in the handle()
public function handle(Request $request, Closure $next) {
$data = $request->all();
foreach ($data as $array) {
//HOW TO USE THE CUSTOM RULE HERE?
}
return next($request);
}
here's the custom rule App\Rules
class MyRule {
public function construct() {}
public function passes($attribute, $value) {
if ($value > 1) {
return false;
}
return true;
}
public function message() {
return "data invalid";
}
}

You have role column in database. It preserves access to your role relation collection. You should delete it or rename role() relation for example to roles(). Moreover, belongsToMany implies that user can have many roles.
In addition, I want to note that the collection has its own methods in_array => contains, array_pluck => pluck. You could optimize your code like that:
public function roles()
{
return $this->belongsToMany(Role::class, 'user_role');
}
public function isEmloyee(){
return $this->roles->isNotEmpty();
}
public function hasRole($name){
return $this->roles->pluck('name')->contains($name);
}
public function makeEmployee($name){
$role = Role::where('name', $name)->first();
if($role){
$this->role()->attach($role->id);
}
}
I have a controller like this:
public function __construct()
{
$check = Auth::id();
if ($check->role == '5') {
// allow to run any other controller
} else {
// return view('home')
}
return $check;
}
public function index()
{
return view('admin.home');
}
What I want to do is whenever, AdminController is triggered, run __construct function and check if role == 5, if it is, proceed with the request, else return view. How can that be done?
Edit
public function handle($request, Closure $next)
{
if ($request->role == 2) {
} else {
return view('index');
}
return $next($request);
}
Kernel:
protected $middlewareGroups = [
'admin' => [
\App\Http\Middleware\CheckAdmin::class,
],
];
Route:
Route::group(['middleware' => ['admin']], function () {
Error::
(1/1) FatalThrowableError Call to a member function setCookie() on
null in VerifyCsrfToken.php (line 156)
view() returns a Illuminate\View\View object, instead of a Illuminate\Http\Response. So instead of sending the view. Redirect the user to index route
Try this
public function handle($request, Closure $next)
{
if ($request->role != 2) {
return return redirect()->route('index');
}
return $next($request);
}
I need to associate some models with at least two other models in an app that I'm developing, but I can't do the association in the controllers.
Here's the code.
UserModel
public function prices() {
return $this->hasMany(PriceClass::class);
}
PriceModel
public function user() {
return $this->belogsTo(ClassOfTheUser::class);
}
public function price_lines() {
return $this->hasMany(PriceLinesClass::class);
}
AreaModel
public function price_lines() {
return $this->hasMany(PriceLineClass::class);
}
PriceLinesModel
public function area() {
return $this->belongsTo(AreaClass::class);
}
public function price() {
return $this->belongsTo(PriceClass::class);
}
How may I do the creation of the Price, if I can't do something like:
public function store(Request $request) {
if ($request->ajax()) {
$user = UserClass::findOfFail($request->input("user_id"));
$user->prices()->save(new PriceClass());
$price = $user->prices()->lastest()->first();
foreach($request->input("price_lines") as $price_line) {
$area = AreaClass::findOrFail($price_line["area_id"]);
$area->price_lines()->save(new PriceLineClass());
$price_line_instance = $area->price_lines()->lastest()->first();
$price->price_lines()->save($price_line_instance);
}
}
}
I'm a new user of Slim framework, I've a simple Slim 3 application, with sign in and sign up validation. But I'm not really sure if this is the right/best way to set errors and check if user is logged in -In order to redirect it to his account if session user.id exists.
I used a middleware: AuthMiddleware which includes:
class AuthMiddleware
{
protected $container;
public function __construct($container)
{
$this->container = $container;
}
public function __invoke($request, $response, $next)
{
if (isset($_SESSION['user.id']) && !empty($_SESSION['user.id'])) {
return $response->withRedirect($this->container->router->pathFor('user.index'));
}
$twig = $this->container->view->getEnvironment();
if (isset($_SESSION['validation'])) {
$twig->addGlobal('errors', $_SESSION['validation']['errors']);
$twig->addGlobal('values', $_SESSION['validation']['values']);
unset($_SESSION['validation']);
}
if (isset($_SESSION['auth.signup.success'])) {
$twig->addGlobal('auth_signup_success', $_SESSION['auth.signup.success']);
unset($_SESSION['auth.signup.success']);
}
if (isset($_SESSION['auth.signin.failed'])) {
$twig->addGlobal('auth_signin_failed', $_SESSION['auth.signin.failed']);
unset($_SESSION['auth.signin.failed']);
}
$response = $next($request, $response);
return $response;
}
}
And I used Twig for my views.
Session validation assigned in the validator.php which includes:
class Validator
{
protected $errors = [];
protected $values = [];
public function validate($request, $rules)
{
foreach ($rules as $field => $rule) {
$this->values[$field] = $request->getParam($field);
try {
$rule->setName(ucfirst($field))->assert($request->getParam($field));
} catch (NestedValidationException $e) {
$this->errors[$field] = $e->getMessages()[0];
}
}
if ($this->failed()) {
$_SESSION['validation'] = [
'errors' => $this->errors,
'values' => $this->values,
];
}
return $this;
}
public function failed()
{
return !empty($this->errors);
}
}
Using Respect\Validation. Also, is this the right use of Middlewares?
Thanks in advance.
try creating a separate file for the methods, and calling it from the middleware:
<?php
class AuthMiddleware extends Middleware {
public function __invoke($request, $response, $next) {
if (!$this->container->auth->check()) {
$this->container->flash->addMessage('danger', 'Please sign in to continue.');
return $response->withRedirect($this->container->router->pathFor('auth.signin'));
}
$response = $next($request, $response);
return $response;
}
}
while the Auth class would have those methods to check:
<?php
public function check () {
return isset($_SESSION['user']);
}
public function user() {
if (isset($_SESSION['user'])) {
return User::find($_SESSION['user'])->first();
} else {
return false;
}
}
Don't forget to include the Auth Class within your $app:
<?php
$container['auth'] = function ($container) {
return new \App\Auth\Auth();
};
I Followed a tutorial with this source code:
https://github.com/laracasts/Dedicated-Query-String-Filtering/tree/master/app
If you have laracasts you can watch the video here
What i like to achieve is filter products based on their category.
When i filter on the product itself , it works fine
class ProductFilter extends QueryFilter
{
public function categorie($name)
{
return $this->builder->where('name' , $name);
}
}
But when i try to filter on the relationship it doens't work. (i get no errors either) . The error is located in this file , i think
class ProductFilter extends QueryFilter
{
public function categorie($name)
{
return $this->builder->categories()->where('name' , $name);
}
}
View
<form method="get" action="/producten/categorie" style="display:inline-block">
#foreach($roots as $root)
<li><button type="submit" name="categorie" value="{{$root->name}}" class="button-link">{{$root->name}}</button></li>
#endforeach
</form>
Route
Route::get('producten/categorie' , 'FrontProductController#index');
FrontProductController
public function index(ProductFilter $filters)
{
Product::filter($filters)->get();
}
QueryFilter class
abstract class QueryFilter
{
protected $request;
protected $builder;
public function __construct(Request $request)
{
$this->request = $request;
}
public function apply(Builder $builder)
{
$this->builder = $builder;
foreach ($this->filters() as $name => $value) {
if (! method_exists($this, $name)) {
continue;
}
if (strlen($value)) {
$this->$name($value);
} else {
$this->$name();
}
}
return $this->builder;
}
public function filters()
{
return $this->request->all();
}
}
Product Model
public function categories()
{
return $this->belongsToMany('App\Category')->withTimestamps();
}
public function scopeFilter($query, QueryFilter $filters)
{
return $filters->apply($query);
}
In the product filter i need to do the following for many-to-many relationships:
public function category($name)
{
return $this->builder->whereHas('categories', function ($query) use ($name) {
$query->where('name', $name);
});
}
