Example: product form

Example source code

Setup

1. Copy sample source to your application
2. Execute db dump from products.sql
3. Update imports in main.php to the following:

'import'=>array(
	'application.models.*',
	'application.models.forms.*',
	'application.components.*',
	'ext.wform.*',
),

4. Now you have access to sample controller:

• Product List: http://yourhost.local/index.php?r=/product
• Create Product: http://yourhost.local/index.php?r=/product/add

Form Layout

Here is what you should see:
