因此，我正在为我的Web应用程序创建carousel，我正在使用新的CodeIgniter 4。到目前为止，我已经成功地上传了图像，但我似乎无法获取图像以在前端显示它。它给我以下错误-尝试读取布尔值上的属性“bannerimg”。

编辑-我正在尝试从数据库中提取所有图像（当前存储了4个图像）
我的数据库表

Database table for carousel - Please check this image too!
下面是代码

在AdminModel中获取图像的函数

//This functions gets the images from db
public function getBanner() {

                $builder = $this->db->table('tblbanner');
                $result = $builder->get();

                if(count($result->getResultArray()) == 1) {

                        return $result->getRow();

                } else {

                        return false;
                        
                }

        }

管理控制器

public function banners() 

    {
        if(!session()->has('logged_staff')) {

                return redirect()->to(base_url(). "/team");
    
        }
        $data = [];
        $data['validation'] = null;
        $suid = session()->get('logged_staff');

        $data['getad'] = $this->adminModel->getBanner(); // This line of fetches the images from database.
        $data['staffdata'] = $this->adminModel->getLoggedStaffData($suid);

        echo view("team/Templates/header_panel");
        echo view("team/navigation", $data);
        echo view("team/sidebar", $data);
        echo view("team/banners", $data);
        echo view("team/Templates/footer_panel");
    }
