Attempted to load interface "NotExistingInterface" from namespace "Symfony\Bundle\FrameworkBundle\Tests\Fixtures\Validation".
Did you forget a "use" statement for another namespace? unable to understand this error
Symfony\Component\Debug\Exception\
ClassNotFoundException
in \vendor/symfony/framework-bundle/Tests/Fixtures/Validation/Article.php (line 5)
<?php
namespace Symfony\Bundle\FrameworkBundle\Tests\Fixtures\Validation;
class Article implements NotExistingInterface
{
public $category;
}
I don't know the error. Please help.
Your code should be like:
<?php
namespace Symfony\Bundle\FrameworkBundle\Tests\Fixtures\Validation;
use Symfony\Bundle\FrameworkBundle\Tests\Fixtures\Validation\NotExistingInterface;
class Article implements NotExistingInterface
{
public $category;
}
It's likely that you have a class in your code called Article, and while using it in some code, forgot a use statement for it.
I ran into the same issue, which is why I'm here =).
It turned out that I hadn't put a use statement for my Article class in some other code, and when executing, it must have decided to use the Article class from the FrameworkBundle tests. Probably some autoloading/autowiring weirdness.
I just had the same problem.
In a controller I needed my Article entity and the IDE suggested me to import the class and I clicked on the wrong one.
Check your imports (use)
You might have a...
use Symfony\FrameworkBundle\Tests\Fixtures\Validation\Article;
instead of a
use App\Entity\Article;

I have started building a new Web App using Symfony, but am having issues using classes.
PhpStorm is able to find the functions within the classes (due to the fact that it gives suggestions when you type $className->.
Also, to prove this is not the same as the other similar questions, I have over simplified it, and even so, the error still occurs.
I have the below in my DefaultController:
<?php
namespace AppBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Request;
use testBundle;
use AppBundle\domainionClasses\firstlevelchecks;
class DefaultController extends Controller
{
/**
* #Route("/register",name="register")
*/
public function registerAction(){
$testClass = new firstlevelchecks();
$testing = $testClass->donothing(); //the IDE knows that the function donothing() exists, in fact it suggests it.
return new Response('');
}
}
The below is the php class located in AppBundle/domainionClasses/test1.php
<?php
namespace AppBundle\domainionClasses;
class firstlevelchecks
{
function donothing(){
return null;
}
}
When loading the /register route, the below Symfony error is displayed:
Attempted to load class "firstlevelchecks" from namespace "AppBundle\domainionClasses".
Did you forget a "use" statement for another namespace?
It is attempting to load the class from the correct name space, and I have used a use statement.
Is there anything I am missing here, or is there a problem with Symfony? This is the first time I used the new version of PhpStorm, and have just downloaded the plugin, also the first time I have experienced this issue :(
Because your file is named test1.php, how can the autoloader know which file to include ?
You shoud rename it to firstlevelchecks.php (= the name and case of your class).
I want to create and use a custom exception class in my CakePhp Application.
So I created a DuplicateConfigurationException.php with the following class skeleton:
<?php
namespace Cake\Exception;
class DuplicateConfigurationException extends Exception{
} ?>
I a controller, where I wish to raise the Exception, I added
use Cake\Exception\DuplicateConfigurationException;
and within a function I call
throw new DuplicateConfigurationException();
Following suggestions throughout the interwebs, I have tried to place the php file in the following locations, but neither of them seems to work:
src/Exception
src/Exceptions
src/Lib
src/Lib/Error
src/Lib/Error/Exceptions
I always get an error:
Error: Class 'Cake\Exception\DuplicateConfigurationException' not found
File /host/var/www/src/Controller/StructuresController.php
Line: 246
What else do I need to do to make Cake recognize my custom exception?
I'm well aware of Loading custom class in CakePHP3, but since this exception is not a separate library I would rather not place it within vendor?
A bit late but I think it might be useful for other users with the same question to have some further explanations.
In fact, with your solution, you rely on native PHP SPL Exception class located in global namespace.
To use Cake's basic Exception class, you missed to add
use Cake\Core\Exception\Exception;
in src/Exceptions/DuplicateConfigurationException.php for loading Cake Exception class constructor. See Cake's book
Your code is working because Cake is handling SPL exceptions the same way than its own Exception class. If you've wanted to go further with a custom handler for instance, it may have broken logic.
Note that class IniPermissionsException extends \Cake\Core\Exception\Exception {}; is also working. In this case, you must prepend \ as the root namespace when calling a class in an extends statement because you need to provide full namespace path.
To swim like a dolphin in Cake's namespaces, just go to API reference.
Full updated code for src/Exceptions/DuplicateConfigurationException.php :
<?php
namespace App\Exceptions;
use Cake\Core\Exception\Exception;
class DuplicateConfigurationException extends Exception {}
?>
Ok, after some fiddling I managed to get it working:
in src/Exceptions/DuplicateConfigurationException.php
<?php
namespace App\Exceptions;
class DuplicateConfigurationException extends \Exception{
} ?>
in the controller:
use App\Exceptions\DuplicateConfigurationException;
...
function somefunction(){
throw new DuplicateConfigurationException();
}
Apparently the namespace should be App\<Folder> and App\<Folder>\<Classname>, respectively.
And I had to prepend Exception with a backslash, since it is used in a namespaced context: http://www.php.net/manual/en/language.namespaces.global.php
Still, I'm not sure where the namespace conventions for CakePhp 3 are documented.
I have two classes in the same folder in own files. But when I am trying to extends one to another it is giving namespace and class not found error.
Info: It is the first time I am extending class using namespace. Also nested namespace is new to me. DB\CRUD So may be I am doing
completely wrong with namespace.
Error message:
Fatal error: Class 'DB\AT_Database' not found in /var/www/...
DB class
File: AT_Database.php
namespace DB;
class AT_Database
{
...
}
CRUD class
File: AT_CRUD.php
namespace DB\CRUD;
use DB\AT_Database;
class AT_CRUD extends AT_Database
{
public function __construct()
{
}
}
This may be silly mistake or may be I have overlooked it (which I should not as a programmer) and that is loading sequence of the class.
May be it's not worth to have as an answer but just adding so by chance in future it can help to someone who make such mistake.
As I mentioned in one of my comment, I am using glob to auto load all class files to include.
foreach ( glob( $this->classes_dir . "/*.php" ) as $class ) {
include_once $class;
}
Now my file names are AT_CRUD.php and AT_Database.php. Here I realized that php loads files in alphabetical order. So when I extends AT_Database class into AT_CRUD its never found.
This is just because php loads AT_CRUD first than AT_Database so either I have to instantiate the class into or to use something like dependancy injection as #prehfeldt mention in his comment.
This is my first question, besides I'm not english-native speaker, so sorry in advance for newbie mistakes...
I'm starting with Symfony2, and I've been facing an autoload problem for a couple of days, i'm getting crazy..
I'm just trying to use a PHP class inside my DefaultController of my AppBundle. I've read the way of doing this is by creating a service in my config.yml and giving a namespace to that class that matches.
Symfony tells me that it does found the file but the class is not in it, the exact error is:
The autoloader expected class "Priceget\CollectorBundle\Crawler\Amazon" to be defined in file "/srv/www/lol.com/public_html/priceget/symfony/src/Priceget/CollectorBundle/Crawler/Amazon.php". The file was found but the class was not in it, the class name or namespace probably has a typo.
And my class is just this:
<?php
namespace Priceget\CollectorBundle\Crawler\Amazon;
use Symfony\Component\HttpFoundation\Response;
class Amazon
{
public function getAll()
{
return new Response('l0l');
}
}
In my DefaultController I'm calling it like that:
<?php
namespace Priceget\CollectorBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Guzzle\Http\Client;
use Symfony\Component\DomCrawler\Crawler;
use Priceget\CollectorBundle\Crawler\Amazon;
class DefaultController extends Controller
{
public function indexAction()
{
$amazon = $this->get('amazon.crawler');
}
}
And my config.yml piece:
services:
amazon.crawler:
class: Priceget\CollectorBundle\Crawler\Amazon
I've already tried to:
Empty cache
Restart apache
Extend the class to Controller? :-Z
Thank you so much in advance.
Your namespace is wrong, rename it:
from: namespace Priceget\CollectorBundle\Crawler\Amazon;
to: namespace Priceget\CollectorBundle\Crawler;
This error also occurs if you do not put <?php in the beginning of the file.
In addition to what's said by Igor, you obviously have to change the FQN class name in the service declaration (YML) if you want it to work.
This can be a bit misleading, it also happens if you don't extend your class correctly. In my instance I tried to extend a repository with an incorrect FQN:
class FilesRepository extends Doctrine\ORM\EntityRepository
should have been:
class FilesRepository extends \Doctrine\ORM\EntityRepository
Notice the missing backslash (\).
Im trying to figure out how namespaces works in PHP, but havent really been lucky
Hope somebody could tell me what Im doing wrong here :)
code
require_once 'Vatcode.php';
$Vatcode = new \resource\Vatcode();
Vatcode.php
namespace resource;
require_once Ini::get('path/class').'/Resource.php';
class Vatcode extends Resource {
public function __construct(){
echo 'works!';
}
}
Rescource.php
namespace resource;
class Resource {
}
error
Fatal error: Class 'resource\Ini' not found in Vatcode.php
it's just a problem of namespace.
Your class Vatcode is in namesapce ressource. If, in the file of VatCode declaration you use nameofclas::... or new nameofclass() it will try to get the class in namespace ressource.
If you want to use the class Ini inside your document you have two solutions :
first give the full qualified name :
require \namespace\of\ini\Ini::get('path/class').'/Resource.php';
second using the "use" keyworld before using the get method :
use \namespace\of\ini\Ini;
require_once Ini::get('path/class').'/Resource.php';
In any case, if Ini is in "no namespace" (global namespace is the accurate word) you just has to use the solutions I gave you but only with \Ini instead of \namespace\of\ini\Ini
