Form Generation Library

[eluser]happydude[/eluser]
Yeah, I know. This is not the best code in the world... because I am still a rookie.

But, the concept follow a laid down form generation library structure.

The problem I am having with this is that when I click the submit button regardless of whether the data validates (and updates the database) or does not, it is the old database values that get populated as default values in the fields..... until the next edit of the same row comes up.

Is there any way I can make the newly posted data display as default values in the form.... especially if the form doesn't validate.

Thanks in advance. See the code below:

Code:

function update($id='')
    {
        if ( ! $id ) redirect ('admin/catalog');
        
        $data = $this->product->get($id);
        
        if ( ! $data ) redirect ('admin/catalog');
        
        $this->load->library('form');
        
        $this->data['title'] = 'Add Product';
        $this->data['add_type'] = 'Product';
        
        
        $categories     = $this->admin->prep_for_select('categories');
        $brands            = $this->admin->prep_for_select('brands');
        $sort            = array (1=>1, 2, 3, 4, 5);
        $checked = ($data['featured'] == 1) ? TRUE : FALSE;
        
        $this->form
                 ->open('admin/update/'.$id)
                ->fieldset()
                ->text('name', 'Product Name', 'trim|required|max_length[255]|xss_clean', $data['name'])
                ->text('reference', 'Product Reference', 'trim|required|numeric|xss_clean', $data['reference_id'])
                ->text('quantity', 'Quantity', 'trim|numeric|xss_clean', $data['quantity'])
                ->iupload('userfile', 'Product Image')->br()
                ->select('category', $categories, 'Category', $data['category_id'], 'trim|required|xss_clean|callback__check_cat')
                ->select('brand', $brands, 'Brand', $data['brand_id'], 'trim|required|xss_clean|callback__check_brand')
                ->textarea('description', 'Description', 'trim|xss_clean', $data['description'])->br()
                ->checkbox('featured', '1','  Feature on Home Page?', $checked, 'trim|xss_clean')->br()->br()
                ->select('sort', $sort, 'Sort Order', $data['sort'], 'trim|xss_clean')
                ->span('e.g. A product with a Sort Order of 3 will be placed higher than one with a sort order of 4 in any listing. It also affects the arrangement of featured products in the sidebar.')->br()->br()
                ->submit('Edit Product', 'submit_product')->reset('Clear')
                    ->validate();
                
                    
    
        if ($this->form->valid) {    
            $input = $this->form->get_post();
            
            $added_by = $modified_by = getField('username');
            $date_added = $date_modified = date('Y-m-d H:i:s');
            
            $params = array ( //prep and typecast the data.
                                 'reference_id'     => (int) $input['reference'],
                                 'name'            => (string) $input['name'],
                                 'category_id'    => (int) $input['category'],
                                 'brand_id'        => (int) $input['brand'],
                                 'description'    => (string) $input['description'],
                                 'quantity'        => (int) $input['quantity'],
                                 'featured'        => (int) $input['featured'],
                                 'image'            => (string)$input['userfile']['name'],
                                 'sort'            => (int) $input['sort'],
                                 'added_by'        => $added_by,
                                 'date_added'    => $date_added,
                                 'modified_by'    => $modified_by,
                                 'date_modified'    => $date_modified,                            
                            );
            
            if( ! isset($input['userfile']['name'])) {
                unset ($params['image']);
            }
                            
            $result = $this->product->update($data['id'], $params);
            
            if ($result) {
                $this->data['message'] = '<p class="success">Your product has been successfully edited. You can add another product below, or '.a('products/'.slug($input['name']).'/'.$data['id'], 'View your recently edited product', 'target="_blank"').'.</p>';
                
            } else {
                $this->data['message'] = '<p class="error">There was a problem editing your product. Please try again later.';
            }                
        }
        
        
        $this->data['resource'] = $data['name'];
        $this->data['form'] = $this->form->get();
        $this->data['errors'] = $this->form->errors;
        $this->view = 'admin/add';
        $this->data['update'] = 'TRUE';

N/B Nevermind $this->data. It justs collects data to be sent into the view. I am using Jamie Rumbelow's MY_Controller.
