Question

I have a section of my code that is causing my whole page to load white with no error message.

I have debuged my code and the following section is causing my issue but I cannot work out why:

Problem Code:

        if($this->image_model->updatePage($id, $caption)) {
                        $data['title'] = 'Image Captions';
                        $data['cms_pages'] = $this->navigation_model->getCMSPages();
                        $data['sales_pages'] = $this->sales_model->getSalesPages();
                        $data['get_images'] = $this->image_model->getImages();
                        $data['content'] = $this->load->view('admin/imagecaption', $data, TRUE); #Loads the "content"
                        $this->load->view('admintemplate', $data); #Loads the given template and passes the $data['content'] into it    

                        }//END if updatePage

Answer 1

In your controller is $this->image_model an instance of your Image_Model class? If so, in the model you posted, there does not appear to be an updatePage() method .
