an exception appears when i am trying to customise registration form using fosuserbundle
Attempted to load class "RegistrationFormType" from namespace "PFE\UserBundle\Form\Type".
Did you forget a "use" statement for another namespace?
mu code
namespace PFE\UserBundle\Form\Type;
use Symfony\Component\Form\FormBuilderInterface;
use FOS\UserBundle\Form\Type\RegistrationFormType as BaseType;
class RegistrationFormType extends BaseType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
parent::buildForm($builder, $options);
$builder->add('nom')->add('prenom');
}
public function getName()
{
return 'pfe_user_registration';
}
}
Probably just adding a \ this way:
use \FOS\UserBundle\Form\Type\RegistrationFormType as BaseType;
Another possible solution is flushing APC. If you have set up APC sometimes it produces this kind of misterious errors.
To do that just restart your Apache, Nginx or the webserver you are using.
I hope this will help.

I am trying to create a class (working as factory class) in my Zend Expressive APP as follows:
declare(strict_types=1);
namespace App\Install\Factory;
use App\Install\Model as Models;
use App\Install\Abstracts\AttributeInterface;
class AttributeEntityFactory{
public static function create($type1 ='Attribute') : AttributeInterface
{
$resolvedClass = "Models\\$type1";
$resolvedClass1 = 'Models\\'.$type1;
//return new $resolvedClass();
//return new $resolvedClass1();
return new Models\Attribute();
}
}
The above code works perfectly for me. However, if try to use any of the other two return statements it shows
Class 'Models\Attribute' not found
How can I achieve dynamic instantiation?
The attribute class code is as follows:
namespace App\Install\Model;
use App\Install\Abstracts\AttributeInterface;
class Attribute implements AttributeInterface
{
protected $attribute;
public function setAttribute($attribute)
{
$this->attribute = $attribute;
}
public function getAttribute()
{
return $this->attribute;
}
}
My PHP version is:
PHP 7.2.13 (cli) (built: Dec 14 2018 04:20:16) ( NTS )
you may need to pass in the full namespace?
"App\Install\Model\" . $type1;
and more...
the model Attribute you have is in the namespace App\Install\Model, and the object you are trying to create is from Models\\ . $type1
maybe you need to change Models to Model
Personally, I would avoid such factory implementation because of several reasons:
It involves magic.
Less predictable code.
Harder to read for both humans and IDE's (E.g: PHPStorm would not find the usages of Attribute class in such code when you need to find it)
Harder to analyze using static analyzers
Instead, I would rewrite this to a more explicit factory, even if I had dozens of different classes in App\Install\Model namespace:
<?php declare(strict_types=1);
namespace App\Install\Factory;
use App\Install\Model as Models;
class AttributeEntityFactory
{
public static function create($type = 'Attribute') : AttributeInterface
{
switch ($type) {
case 'Attribute':
return new Models\Attribute();
case 'SomethingElse':
return new Models\SomethingElse();
default:
throw new \InvalidArgumentException(
sprintf('An unknown type %s requested from %s', $type, __METHOD__)
);
}
}
}
As a rule of thumb:
Never compose classnames / namespaces using strings concatenated with variables / parameters / constants whatever.
Never call methods in such way, too.
You'll thank me when your application/business/codebase grows enough.
I created a service provider named AdminServiceProvider
namespace App\Providers;
use Modules\Orders\Models\Orders;
use Illuminate\Support\ServiceProvider;
use View;
class AdminServiceProvider extends ServiceProvider
{
public function boot()
{
$comments = Orders::get_new_comments();
View::share('comments', $comments);
}
public function register()
{
}
}
Registered the provider
App\Providers\AdminServiceProvider::class,
Now I try to attach it to the controller
namespace App\Http\Controllers\admin;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\Providers\AdminServiceProvider;
class AdminController extends Controller
{
public $lang;
public function __construct()
{
}
public function index(){
return view('admin/dashboard');
}
}
Now I get this error message
Undefined variable: comments
This is the first time I try to use a custom service provider and don't know exactly how it works I'm sure there's something missing Hope you can help. Thanks in advance.
[UPDATE]
removed use App\Providers\AdminServiceProvider; from the controller
php artisan clear-compiled solved the problem but I want to attach it to some controllers not all controllers as the $comments are sent to all contollers in my app. So how to attach the service provider to specific controllers not all of them?
For the undefined variable run: php artisan clear-compiled will solve it
If you want to share a variable in some of your views you can create a middleware and assign it to the views you want to share the data with:
First create a middleware: php artisan make:middleware someName
Then in the handle function you add your view sharing logic:
$comments = Orders::get_new_comments();
view()->share('comments',$comments);
return $next($request);
Then register your middleware under the $routeMiddleware array and
give it an alias.
Then attach it to your routes like:
Route::group(['middleware'=> 'yourMiddlewwareName'], function(){
//your routes
});
If you have all your admin views in one directory (views\admin for example) you can use view composer in AdminServiceProvider:
public function boot()
{
view()->composer('admin.*', function($view){
$view->with('comments', Orders::get_new_comments());
});
}
It will attach comments variable to each view in your views\admin directory.
You can also attach a variable to some specific views or folders like this:
view()->composer(['admin.posts.*', 'admin.pages.index'], function($view){
$view->with('comments', Orders::get_new_comments());
});
Here I want to use session in my all pages any one can help me on this topic. some says create a custom controller in library, and/or use helper/hook, I don't know what will work.
If any one have a little example code and little desc. then please share here.
How can I use session in all pages.?
From the CodeIgniter documentation
Sessions will typically run globally with each page load, so the
Session class should either be initialized in your controller
constructors, or it can be auto-loaded by the system. For the most
part the session class will run unattended in the background, so
simply initializing the class will cause it to read, create, and
update sessions when necessary.
To initialize the Session class manually in your controller
constructor, use the $this->load->library() method:
$this->load->library('session');
So, in order to initialize the Session library in ALL your controllers, the best idea is to have a custom "general controller"
<?php
class MyController extends CI_Controller {
public function __construct()
{
$this->load->library('session');
}
}
and then have all your contollers extend not the default CI_Controller, but your "MyContoller", like in
<?php
class Blog extends MyController {
public function index()
{
echo 'Hello World!';
}
}
I hope this is what you need.
I want to use my custom Trait stored in app directory into my controller. However I always get this message:
Trait 'app\MessageTrait' not found
My Controller:
namespace app\Http\Controllers;
use Illuminate\Http\Request;
use Auth;
use app\Http\Requests;
use app\User;
use app\MessageTrait;
class login extends Controller{
use MessageTrait;
public function index(Request $request){
return back();
}
}
My MessageTrait is contained within MessageTrait.php, located in app directory. Code looks like this:
My Trait:
trait MessageTrait{
public function success(){
return 'success';
}
public function error($message){
return 'error';
}
}
First I thought it may be a Namespace issue - however, User class could be found using same namespacing as my MessageTrait. Any ideas?
I solved this by adding namespace app to the top line of my Trait file. Everything works as expected now!
In an attempt to try and narrow my query down, I'm still very new to Codeigniter framework...
I want to define global variables (eg. in autoloaded helpers) and use global mysql queries throughout my site - but I don't understand how to do the latter (global mysql queries).
I understand the concept of defining single variables in a helper... and I understand the concept of creating a single mysql query in a model, loading it in a controller and using it in a view file (with a foreach loop).
How (and where) do I create a mysql query that can be autoloaded (or whatever) and used anywhere on my site - without the need to load it in every controller?
this might help.. models would probably be your best bet. below i have given some insite on how to use controlelrs/models/libraries in general, i would put my mysql code into the appropriate model file. and call it via any controller
// Library/profiles.php
class My_library
{
protected $CI;
public function __construct()
{
$this->CI =& get_instance(); // Existing Code Igniter Instance
}
public function my_lib_method()
{
// Your Code Here
// can communicate back with CI by using $this->CI
// $this->CI->load->view(....);
// $this->CI->load->model(...);
// ETC
}
}
// models/my_model.php
class My_model extends CI_Model{
public function my_mdl_method(){
// Your Code Here
}
}
// controllers/my_controller.php
class My_controller extends CI_Controller
{
public function my_ctrl_method(){
$this->load->library('my_library');
$this->load->model('my_model');
// calling a library method
$this->my_library->my_lib_method();
// calling a model method
$this->my_model->my_mdl_method();
}
}
