6.7.3. A Product Controller

Implementation of the product controller is similar to what we did for the customer controller:

  1. <?php
  3. /*
  4.  * Product Controller
  5.  */
  6. namespace App\Http\Controllers;
  8. use App\Http\Controllers\Controller;
  9. use App\Product;
  11. class ProductController extends Controller {
  13.   /**
  14.    * Displays a list of products
  15.    *
  16.    * @return Response
  17.    */
  18.   public function showProducts() {
  19.     // Connect widget for search
  20.     $filter = \DataFilter::source(new Product);
  21.     // The search will be by product name
  22.     $filter->add('NAME', 'Name', 'text');
  23.     $filter->submit('Search');
  24.     $filter->reset('Reset');
  25.     // Create a grid to display the filtered data
  26.     $grid = \DataGrid::source($filter);
  27.     // output grid columns
  28.     // Field, label, sorting
  29.     $grid->add('NAME', 'Name', true);
  30.     // Set the format with 2 decimal places
  31.     $grid->add('PRICE|number_format[2,., ]', 'Price');
  32.     $grid->row(function($row) {
  33.       // Press the money values to the right
  34.       $row->cell('PRICE')->style("text-align: right");
  35.     });
  36.     // Add buttons to view, edit and delete records
  37.     $grid->edit('/product/edit', 'Edit', 'show|modify|delete');
  38.     // Add the Add product button
  39.     $grid->link('/product/edit', "?????????? ??????", "TR");
  40.     // set sorting
  41.     $grid->orderBy('NAME', 'asc');
  42.     // set the number of records per page
  43.     $grid->paginate(10);
  44.     // display the customer template and pass the filter and grid to it
  45.     return view('product', compact('filter', 'grid'));
  46.   }
  48.   /**
  49.    * Add, edit and delete products
  50.    *
  51.    * @return Response
  52.    */
  53.   public function editProduct() {
  54.     if (\Input::get('do_delete') == 1)
  55.       return "not the first";
  56.     // create editor
  57.     $edit = \DataEdit::source(new Product());
  58.     // Set the title of the dialog, depending on the type of operation
  59.     switch ($edit->status) {
  60.       case 'create':
  61.         $edit->label('Add product');
  62.         break;
  63.       case 'modify':
  64.         $edit->label('Edit product');
  65.         break;
  66.       case 'do_delete':
  67.         $edit->label('Delete product');
  68.         break;
  69.       case 'show':
  70.         $edit->label("Product's card");
  71.         $edit->link('products', 'Back', 'TR');
  72.         break;
  73.     }
  74.     // set that after the operations of adding, editing and deleting,
  75.     // you need to return to the list of products
  76.     $edit->back('insert|update|do_delete', 'products');
  77.     // We add editors of a certain type, assign them a label and
  78.     // associate them with the attributes of the model
  79.     $edit->add('NAME', 'Name', 'text')->rule('required|max:100');
  80.     $edit->add('PRICE', 'Price', 'text')->rule('max:19');
  81.     $edit->add('DESCRIPTION', 'Description', 'textarea')
  82.          ->attributes(['rows' => 8])
  83.          ->rule('max:8192');
  84.     // display the template product_edit and pass it to the editor
  85.     return $edit->view('product_edit', compact('edit'));
  86.   }
  87. }
