Question

I am new in symfony2, I would like to register some user in my profile_tbl. here is my code in the controller.

 <?php

    namespace Ai\QABlogBundle\Controller;

    use Ai\QABlogBundle\Entity\Profile_tbl;
    use Symfony\Bundle\FrameworkBundle\Controller\Controller;
    use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
    use Symfony\Component\HttpFoundation\Request;
    use Symfony\Component\HttpFoundation\Response;



    class QABlogController extends Controller
    {

        /**
        *@Route("/" , name= "home")
        */
        public function homeAction()
        {
            return $this->render('AiQABlogBundle:QABlog:primaries/index.html.twig');

        }

        /**
        *@Route("/register/" ,name= "register")
        */

        public function registerAction(Request $request)
        {
            $profile = new Profile_tbl();

            $form  = $this -> createFormBuilder($profile)
                    -> add ('fname' , 'text')
                    -> add ('lname' , 'text')
                    -> add ('gender' , 'text')
                    -> add ('email' , 'text')
                    -> add ('register' , 'submit')
                    ->getForm();

            $form->handleRequest($request);
            if ($form->isValid()) {

                $em = $this->getDoctrine()->getManager();
                $em->persist($profile);
                $em->flush();
                return new Response('News added successfuly');
            }

             $build['form'] = $form->createView();
             return $this->render('AiQABlogBundle:QABlog:primaries/registration.html.twig', $build);
        }


    }

I try to rename or make another entity ..

steps that I tried to generate my new entity. Creating Database:

php app/console doctrine:database:create

Generate Entity:

php app/console doctrine:generate:entity

Generate the Getters and Setters:

php app/console doctrine:generate:entities AiQABlogBundle

after this I run it in my browser.

and gives me an error ,

Attempted to load class "Profile" from namespace "Ai\QABlogBundle\Controller". Did you forget a "use" statement for e.g. "Twig_Profiler_Profile" or "Symfony\Component\HttpKernel\Profiler\Profile"?

Answer 1

This happened to me a few times. It usually happens when I copy-paste an old class file to create a new class. Check your classname and the filename of the file containing your class; they should be the same. In your case they should be Profile_tbl and Profile_tbl .php respectively.

Update

Profile_tbl is converted to Profile/tbl.php as per the PSR-0 autoload convention which Composer uses by default to load classes inside the src/ directory. You'll have to rename the class to something that does not use an underscore e.g. ProfileTbl or simply Profile.

// This should be in the file: src/Ai/QABlogBundle/Entity/Profile.php
namespace Ai\QABlogBundle\Entity;

/**
 * Profile
 *
 * @ORM\Table()
 * @ORM\Entity
 */
class Profile
{
    // ...
}
