Commerce Commerce 1.x Developer Admin Data Management

To manage data from the Commerce dashboard, you’ll need:

• A Page class for each action (overview, create, update)
• A Grid class that lists your objects allowing the user to do stuff with it
• A FormWidget instance that defines the fields to use.
• A menu item to point to your overview page
• A module to tie it all together!

Your xPDO model will need to be loaded in Commerce (using a Module that calls $this->adapter->loadPackage in its initalize method).

Your xPDO object will need to extend comSimpleObject, otherwise the built-in form handling will not work.

You’ll need a couple of page classes in most cases. These are:

• Overview, containing the Grid widget that lists your existing objects, as well as having a “Add Object” button and actions on existing objects.
• Create, containing the Form widget to create new objects with.
• Update, containing logic on loading the object to edit and loading the form widget to edit that object.
• Delete, along with a DeleteForm class, to handle deleting an object.

It’s recommended to put all of these in the same directory and namespace, grouped by object/feature, inside an Admin subnamespace.

In this example we’re using the namespace MeMyselfAndI\AwesomeExtension\Admin\ToDo. As all classes are in the same namespace, we don’t have to include the full class name in references.

#Overview Page with Grid

File: core/components/commerce_awesomeextension/src/Admin/ToDo/Overview.php

Contents:

<?php
namespace MeMyselfAndI\AwesomeExtension\Admin\ToDo;

use modmore\Commerce\Admin\Page;
use modmore\Commerce\Admin\Sections\SimpleSection;

class Overview extends Page {
    public $key = 'todo-overview';
    public $title = 'commerce_todo.todos';

    public function setUp()
    {
        $section = new SimpleSection($this->commerce, [
            'title' => $this->getTitle()
        ]);
        $section->addWidget(new Grid($this->commerce));
        $this->addSection($section);
        return $this;
    }
}

We’re creating a simple section, giving it a title of commerce_todo.todos (which is expected to be a lexicon), and then add an instance of Grid to it.

Let’s create the Grid.

File: core/components/commerce_awesomeextension/src/Admin/ToDo/Grid.php

<?php
namespace MeMyselfAndI\AwesomeExtension\Admin\ToDo;

use modmore\Commerce\Admin\Widgets\GridWidget;
use modmore\Commerce\Admin\Util\Action;

class Grid extends GridWidget {
    public $key = 'todos';
    public $defaultSort = 'name';

    public function getItems(array $options = array())
    {
        $items = [];

        $c = $this->adapter->newQuery('MyExtTodo');

        // If you want to do any filtering, this is the place!

        // Get the total count for pagination
        $count = $this->adapter->getCount('MyExtTodo', $c);
        $this->setTotalCount($count);

        // Set the current page limit and load the object
        $c->limit($options['limit'], $options['start']);
        $collection = $this->adapter->getCollection('MyExtTodo', $c);

        foreach ($collection as $object) {
            $items[] = $this->prepareItem($object);
        }

        return $items;
    }

    public function getColumns(array $options = array())
    {
        return [
            [
                'name' => 'id',
                'hidden' => true,
            ],
            [
                'name' => 'task',
                'title' => $this->adapter->lexicon('commerce_todos.task'),
                'sortable' => true,
            ],
            [
                'name' => 'when',
                'title' => $this->adapter->lexicon('commerce_todos.when'),
                'sortable' => true,
            ],
        ];
    }

    public function getTopToolbar(array $options = array())
    {
        $toolbar = [];

        $toolbar[] = [
            'name' => 'add-todo',
            'title' => $this->adapter->lexicon('commerce_todos.add_todo'),
            'type' => 'button',
            'link' => $this->adapter->makeAdminUrl('todos/create'),
            'button_class' => 'commerce-ajax-modal',
            'icon_class' => 'icon-plus',
            'modal_title' => $this->adapter->lexicon('commerce_todos.add_todo'),
            'position' => 'top',
        ];

        $toolbar[] = [
            'name' => 'limit',
            'title' => $this->adapter->lexicon('commerce.limit'),
            'type' => 'textfield',
            'value' => (int)$options['limit'],
            'position' => 'bottom',
            'width' => 'two wide',
        ];

        return $toolbar;
    }

    public function prepareItem(MyExtTodo $todo)
    {
        $item = $todo->toArray('', false, true);

        $item['actions'] = [];

        $editUrl = $this->adapter->makeAdminUrl('todos/update', ['id' => $item['id']]);
        $item['actions'][] = (new Action())
            ->setUrl($editUrl)
            ->setTitle($this->adapter->lexicon('commerce_todos.todo.edit'))
            ->setIcon('icon-edit');

        $deleteUrl = $this->adapter->makeAdminUrl('todos/delete', ['id' => $item['id']]);
        $item['actions'][] = (new Action())
            ->setUrl($deleteUrl)
            ->setTitle($this->adapter->lexicon('commerce_todos.todo.delete'))
            ->setIcon('icon-trash');

        return $item;
    }
}

Lots of things are happening in the grid.

• First we get the items in a way that allows pagination.
• We define the columns that are shown in the table. With lexicons for names, and defining if columns are sortable.
• We define toolbar options. One button, to add a new to do, and the limit field that allows the user to change how many results are shown.
• We turn our MyExtTodo object into an array. This can do all sorts of pre-processing of the data, but in this example we just return the object’s data as-is. We also add Actions that will be shown for each row, with links to edit and delete the object.

#Top toolbar filter types

• textfield
• datefield (as of 1.4)
• select, provide a optgroups array of [label => [ [value => 'val', label => 'val label'] ] or options array of [ [value => 'val', label => 'val label'] ].
• button, acts as a link or a dropdown menu
• anything else will just render the title in the toolbar
