I'm trying to learn how to use Laravel 5, but I've bumped into a problem. I've created the following code so far:
under app/HTTP/routes.php:
<?php
Route::get('/', 'MyController#home');
Created my own MyController.php file under app\Http\Controllers and added the following code to the controller:
<?php
namespace App\Http\Controllers;
use Illuminate\Routing\Controller as BaseController;
class MyController extends BaseController
{
public function home()
{
$name = "John Doe";
return View::make("index")->with("name", $name);
}
}
When I run the app I get the error:
FatalErrorException in MyController.php line 12:
Class 'App\Http\Controllers\View' not found
What am I doing wrong?
Change
return View::make("index")->with("name", $name);
To
return \View::make("index")->with("name", $name);
or Even better
return view("index",compact('name'));
UPDATE
View is a Facade, a wrapper class, and view() is a helper function that retrives a view instance.

I have a file that i put in app\Classes\myVendor\dev_client_api.php. This file has a class in it:
class someClass{
//stuff
}
I want to use this class in a controller.
In my controller I have done the following:
namespace App\Classes\myVendor;
use dev_client_api;
class myController extends Controller
{
///stuff
public function processData(Request $request){
$client = new someClass($vars);
}
}
When i execute this page I get:
Class 'App\Classes\myVendor\Controller' not found
I have to admit I am not sure what exactly I am doing. Any help would be great.
I assume your Controllers are in Laravel's default App\Http\Controller directory.
namespace App\Classes\myVendor;
class someClass {
//stuff
}
namespace App\Http\Controllers;
use App\Classes\myVendor\someClass;
class myController extends Controller
{
///stuff
public function processData(Request $request){
$client = new someClass($vars);
}
}
I want to call a function of CommonController in PostsController.
PostsController is in Posting namespace
PostController: App\Http\Controllers\Posting\PostsController
CommonController: App\Http\Controllers\CommonController
I tried this code but it did not work in PostingController, it is a small code from my PostingController
namespace App\Http\Controllers\Employer;
use App\Http\Controllers\CommonController;
class PostsController extends Controller
{
public function myFunction(Request $request, $id){
$commonControllerObj = new CommonContoller;
$result = $commonControllerObj->commonCallingFunction($id);
}
}
but it did not work, its giving error
Class 'App\Http\Controllers\Posting\CommonContoller' not found
The first your namespace is wrong
namespace App\Http\Controllers\Posting;
The second you can call another Controller like this
app('App\Http\Controllers\CommonController')->commonCallingFunction();
This will work, but this is bad in terms of code organisation
You can extends Controller like this
use App\Http\Controllers\CommonContoller;
class PostsController extends CommonContoller
{
public function myFunction(Request $request, $id){
$result = $this->commonCallingFunction($id);
}
}
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 ;-)
I am new to Laravel, I am trying things around while going through a tutorial. This is where I am facing an unexpected behaviour.
I have a model tweet and a controller named tweetsController; when I call tweet::find() or any similar method I found this:
FatalErrorException in tweetsController.php line 13:
Class 'App\Http\Controllers\tweet' not found
I have also tried App\tweet::find().
Everything seems fine through tinker.
Please explain.
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
class tweetsController extends Controller
{
public function show(){
$data = tweet::first()->tweetBody;
return view('tweets.list',['passedData'=> $data]);
}
public function delete($id){
return "here we dele the tweet ".$id;
}
public function add(){
return "i add your tweet to database then show you all the tweets";
}
}
tweet.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class tweet extends Model
{
protected $fillable = array(
'tweetHead',
'tweetBody'
);
}
?>
A few options the maybe generating this error:
The model/controller namespace is incorrect;
The name of the file and the class name for the model needs to be "Tweet" with the first letter in uppercase;
If you set the right namespace on the model "Tweet.php" and import that on your "TweetController.php"
I hope that helps :)
UPDATE:
In the TweetController.php add this
use App\Tweet;
Before the class declaration, like this
use App\Tweet;
class tweetsController extends Controller
{
And remember to change the controller name in the class declaration like this
class TweetsController extends Controller
{
And the controller filename will become "TweetsController.php"
The Model also has to be named "Tweet" and not "tweet" in the class declaration and the filename
class tweet extends Model
will become
class Tweet extends Model
and the file will be named "Tweet.php"
and everytime you need to call the model you will do this
public function show(){
$data = App\Tweet::first()->tweetBody;
return view('tweets.list',['passedData'=> $data]);
}
Add use Add\User below namespace in your controller
I have created Mycontoller.php inside app/controllers
class MyController extends BaseController {
public function showWelcome($name){
return "Hello $name !! ";
}
}
When i use inside routes.php
Route::get('user/{name}','App\Controllers\MyController#showWelcome');
It is giving exception
ReflectionException Class App\Controllers\MyController does not exist
just use MyController#showWelcome With the code you showed, you don't have any defined namespaces. You should make it
Route::get('user/{name}','App\Controllers\MyController#showWelcome');
