更新信息时如何显示图像

Question

我想在编辑用户信息时显示图像。我只是将表单与获取的数据绑定在一起，并使用单个数组即表单显示所有数据。还有什么办法可以得到https 500错误？如果是，那么请向我显示一些代码，以便我可以显示该错误并检查为什么它给出了HTTPS 500错误。

public function editAction() {
        $id = (int) $this->params()->fromRoute('id', 0);
        if (!$id) {
            return $this->redirect()->toRoute('business', array(
                        'action' => 'add'
            ));
        }
        try {
            $business = $this->getBusinessTable()->getBusiness($id);
        } catch (\Exception $ex) {
            return $this->redirect()->toRoute('business', array(
                        'action' => 'index'
            ));
        }

        $form = new BusinessForm();
        $form->bind($business); /// values to the form
        $form->get('submit')->setAttribute('value', 'Update business info');

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

                $post = array_merge_recursive(
                    $request->getPost()->toArray(),
                    $request->getFiles()->toArray()
                 );
              $form->setData($post);
            if ($form->isValid()) {
                $this->getBusinessTable()->saveBusiness($business);

                // Redirect to list of Student
                return $this->redirect()->toRoute('business');
            }
        }

        return array(
            'id' => $id,
            'form' => $form,
        );
    }
