Laravel Redirect from Helper Class - php

I'm trying to redirect to an external URL from a helper class.
Here's my controller:
<?php
namespace App\Http\Controllers;
use App\Lead;
use Illuminate\Http\Request;
use App;
use Helper;
class MyController extends Controller
{
public function entities_get() {
Helper::my_function(); // <---- Call my Helper class method to redirect.
return view( 'template' );
}
}
Here's my helper class used in the controller:
<?php
namespace App\Helpers;
class Helper
{
public static function my_function()
{
return redirect()->away( 'https://www.google.com' ); // <---- Not redirecting.
}
}
Why is the redirect() not working inside my_function()? Do I need to include some Laravel classes using the PHP "use" statement?

You can add send method and it will work.
<?php
namespace App\Helpers;
class Helper
{
public static function my_function()
{
return redirect()->away('https://www.google.com')->send();
}
}

Method in trait not able to be called from controller

I'm trying to use a trait to handle image upload on my Laravel application, but none of the functions in my Trait can be called from the controller.
It throws a BadMethodCallException and says that the function couldn't be found.
I've tried using really simple functions to test if it is a problem with the trait or whether the function itself has an issue, but even a simple return function that only contains
return "sampletext";
has the same issue.
The path of the trait is under App/Traits/UploadTrait
and I've already checked the spelling on the use statement in my controller, which says use App\Traits\UploadTrait;
namespace App\Traits;
trait UploadTrait
{
public function test(){
return "testtext";
}
}
And the controller has
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\DB;
use Illuminate\Validation\Rule;
use App\User;
use App\Profile;
use App\Traits\UploadTrait;
use Image;
class UserProfileController extends Controller
{
...
protection function updateProfile($args, Request $request){
...
return $this->test();
...
Of course I expect the function in my trait to be called, but this does not happen.
You need to use the trait inside your controller and move the $this->test() inside a class function:
<?php
use App\Traits\UploadTrait;
class UserProfileController extends Controller
{
use UploadTrait; // <-- Added this here
public function index()
{
return $this->test(); // <-- Moved this into a function
}
}
You have to put the use keyword to use that trait and its methods in the class
trait UploadTrait
{
public function test(){
return "testtext";
}
}
class Controller{
}
class UserProfileController extends Controller
{
use UploadTrait;
}
$ob = new UserProfileController();
echo $ob->test();
You can make a function to and call the trait function.
More Details
Use trait inside the class like:
use my/path/abcTrait;
Class My class{
use abcTrait;
}
Now, you can call trait functions with $this->functionName () in functions.

Class App\Http\Controllers\Panel does not exist

I'm following the Laracasts series and have run into an issue on the episode Laravel 5.4 From Scratch: Route Model Binding.
Laravel version:
Laravel Framework 5.6.13
The error:
Class App\Http\Controllers\Panel does not exist
This shows on both the /panel and /panel/1 pages
App\Http\Controllers\PanelController.php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
// Code works if I uncomment below line, and change the show function to "show($panel)"
//use App;
class PanelController extends Controller
{
public function index()
{
$panels = Panel::all();
return view('panel/index', compact('panels'));
}
public function show(Panel $panel)
{
return $panel;
return view('panel/show', compact('panel'));
}
}
routes/web.php
// Main panel view
Route::get('/panel', 'PanelController#index');
// Individual panel view
Route::get('/panel/{panel}', 'PanelController#show');
App/Panel.php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Panel extends Model
{
public static function activePanels()
{
return static::where('status', 1)->get();
}
}
Add this line in panel controller before the class
use App\Panel;
You need to add use App\Panel; to top of class
Or call it by full namespace $panels = App\Panel::all();
You don't included your model to class.
Add App\Panel to main include section:
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Panel;
class PanelController extends Controller
{
public function index()
{
$panels = Panel::all();
return view('panel/index', compact('panels'));
}
public function show(Panel $panel)
{
return $panel;
return view('panel/show', compact('panel'));
}
}
or load model in your class method manually:
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class PanelController extends Controller
{
public function index()
{
$panels = App\Panel::all();
return view('panel/index', compact('panels'));
}
public function show(Panel $panel)
{
return $panel;
return view('panel/show', compact('panel'));
}
}

PHP/Laravel parent class variable is null when calling from different controllers

Parent Class:
<?php
namespace App\Services;
class RequestVariables {
protected static $keys_tour;
public static function init() {
self::$keys_tour = array_flip(['tour_type', 'city_from']);
}
}
Child Class:
<?php
namespace App\Services;
class PreviousVersions extends RequestVariables {
public static function createVersion ($tour) {
dd(parent::$keys_tour);
}
}
When I call PreviousVersions::createVersion() from 1st controller:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Services\PreviousVersions;
use App\Tour;
class Tours2Controller extends Controller
{
public static function PreProcess($tour)
{
PreviousVersions::createVersion($tour);
}
}
it outputs what's expected:
array:2 [
"tour_type" => 0
"city_from" => 1 ]
but when I execute the same function in another controller:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Tour;
use App\Services\PreviousVersions;
class BookingController extends Controller {
public function booking($tour)
{
PreviousVersions::createVersion($tour);
}
}
it outputs 'null'
I can't see what's different between my controllers causing different results when calling the same method. Can somebody tell me why it outputs 'null' in the 2nd case?
If you need more information, please ask.
The $keys_tour property is being set inside the init() method of the RequestVariables class.
You can solve it by calling RequestVariables::init() inside the createVersions() method:
public static function createVersion ($tour)
{
RequestVariables::init();
}
Or using the parent keyword:
public static function createVersion ($tour)
{
parent::init();
}

Call the UI function in controller class in laravel

UI Code: in resources\views\DistributorRegistration.php
<?php
class DistributorRegitrationForm
{
public function distributorRegitrationFormHtml(){
return '<h1>Hello</h1>';
}
}
?>
In Controler Class.....
namespace App\Http\Controllers;
use App\User;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use resources\views\DistributorRegistration;
class DistributorRegistration extends Controller
{
function VestigePOS_GRNHandler(Request $request){
$id = $request->input('id');
return view(DistributorRegitrationForm::distributorRegitrationFormHtml()) ;
}
}
When I call this controller in routes
Fatal error: Class 'App\Http\Controllers\DistributorRegitrationForm' not found
Which file contains the class DistributorRegitrationForm? I'm missing an use App\...\DistributorRegitrationForm; in the controller, if it's not in the same namespace.
Calling DistributorRegitrationForm::distributorRegitrationFormHtml() won't work, unless the method becomes a static method (public static function).
You have some typos in there ;-)

Laravel 5 fails to pass variable to all views

I have a problem with passing variable (data) to all Views. I created BaseController that extends default Laravel controller and "global" variables are defined there. When I extend other controller with BaseController i got error that variable is not defined. Does someone knows where's the problem?
Here is code:
namespace App\Http\Controllers;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Sentry;
use Illuminate\Http\Request;
use View;
class BaseController extends Controller {
public function __construct() {
$obavijesti="Other data";
$izbornici="Some data";
View::share ( 'izbornici', $izbornici );
View::share ( 'obavjesti', $obavjesti );
}
}
class AdminController extends BaseController {
.
.
.
echo '<pre>';var_dump($izbornici);echo '</pre>';//Error pop ups here
.
.
.
}
You are doing something wrong here. view::share() is used for sharing a piece of data across all views not controller.
namespace App\Http\Controllers;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Sentry;
use Illuminate\Http\Request;
use View;
//If you wish to get these variables in your other controllers you do this:
class BaseController extends Controller {
public $obavijesti="Other data";
public $izbornici="Some data";
public function __construct() {
View::share ( 'izbornici', $this->izbornici );
View::share ( 'obavjesti', $this->obavjesti );
}
}
class AdminController extends BaseController {
//if you have a constructor in other controllers you need call constructor of parent controller (i.e. BaseController) like so:
public function __construct(){
parent::__construct();
}
public function Index(){
echo $this->obavijesti;
}
}
You can also use a composer to share variables to views
//1. Create a composer file at app\Composers\AdminComposer.php
//NB: create "app\Composers" if does not exists
//2. Inside AdminComposer.php add this.
<?php namespace App\Composers;
class AdminComposer
{
public function __construct()
{
}
public function compose($view)
{
//Add your variables
$view->with('izbornici', 'Other data')
->with('obavjesti', 'Some other data');
}
}
//3. In you controller do this:
<?php namespace App\Http\Controllers;
//NB: I removed your BaseController because I believe the issue is coming from //there
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Sentry;
use Illuminate\Http\Request;
use View;
class AdminController extends Controller{
public function __construct(){
//Lets use AdminComposer to share variables to adminpage.blade.php view
View::composers([
'App\Composers\AdminComposer' => array('adminpage')
]);
}
public function Index(){
return view('adminpage');
}
}
Ideally you're going to want a combination of what you have, and the other answer posted here.
<?php
class BaseController extends Controller {
protected $obavijesti = 'Other data';
protected $izbornici = 'Some data';
public function __construct() {
View::share('obavjesti', $this->obavjesti);
View::share('izbornici', $this->izbornici);
}
}
Then in all of your views, you have access to the variables $obavjesti and $izbornici. Now in your other controllers, anything that extends BaseController can do the following:
class AdminController extends BaseController {
public function index() {
echo $this->ixbornici;
echo $this->obavjesti;
}
}
