How to defined a variable in zendframework 3 i want to solve the issue

回答1:

Problem is that you're using the $company variable in your return new ViewModel statement, but you only create the variable when the entire form is valid.

Instead of what you're doing, make sure that you provide a Form instance (whichever you need, e.g. CompanyForm) to your controller via the Factory. Then have your function along the lines like below (I've removed some error checking):

public function editAction()
{
    $id = $this->params()->fromRoute('id', null);

    /** @var Company $entity */
    $entity = $this->getObjectManager()->getRepository(Company::class)->find($id);

    /** @var CompanyForm $form */
    $form = $this->getForm();
    $form->bind($entity);

    /** @var Request $request */
    $request = $this->getRequest();
    if ($request->isPost()) {
        $form->setData($request->getPost());

        if ($form->isValid()) {
            /** @var Company $entity */
            $entity = $form->getObject();

            $this->getObjectManager()->persist($entity);

            try {
                $this->getObjectManager()->flush();
            } catch (Exception $e) {

                throw new Exception('Could not save. Error was thrown, details: ', $e->getMessage());
            }

            return $this->redirectToRoute('companies/view', ['id' => $entity->getId()]);
        }
    }

    return [
        'form' => $form,
    ];
}
