Question

Quick question about CI.

I have a view with a form, several text input fields and a file upload.
I want to be able to take the input from the text fields, save it to the DB, and then upload the image.

I’ve achieved this by having the upload code in a controller, and if the upload is successful, a call to my Model is made to update the database.

Is this “best practice”, or indeed an acceptable way of doing it? Or should the File Upload go in the Model. Does it matter?

Essentially my code is:

    function edit_category()
        {
            $config['upload_path'] = 'images/category/';
            $config['allowed_types'] = 'gif|jpg|jpeg|png';
            $config['max_size'] = '1000';
            $config['max_width'] = '300';
            $config['max_height'] = '300';

            $this->load->library('upload', $config);

            if(!$this->upload->do_upload()) 
            {
                $this->session->set_flashdata('status', $this->upload->display_errors());
                        redirect('admin/category/edit/'.$this->input->post('catID'), 'location');
            }
            else  /*no errors, upload is successful..*/
            {
                $fInfo = $this->upload->data();
                //$this->_createThumbnail($fInfo['file_name']);
                            //process form POST data.
                            $data = array(
                                'catName' => $this->input->post('catName'),
                                'catDesc' => $this->input->post('catDesc'),
                                'catImage' => $fInfo['file_name']
                );

/* update the database */
                $category = $this->category_model->edit_category($data, $this->input->post('catID'));

Answer 1

I would put this in a model because I like to keep my controllers as slim as possible. I think of the controller as the link between the views and the back-room processing, not the processing itself.
I’m not sure if this is “best practise” or not. It will certainly work the way you’re doing it too. CodeIgniter allows you to be quite flexible in how you apply mvc theory.
