Abstract class code and interface support code to create more sofisticated view helpers with better setup and protected properties.

Installation

composer require mvccore/ext-view-helper

Example

Your custom primitive view helper code:

// located in `/App/Views/Helpers/FormatNumber.php`

namespace App\Views\Helpers;

class FormatNumber {
	public function FormatNumber ($number) { // $number = 1234.56;
		return number_format($number); // english notation - 1,234
	}
}

... could be more sofisticated with this package:

// located in `/App/Views/Helpers/FormatNumber.php`

namespace App\Views\Helpers;

class FormatNumber extends \MvcCore\Ext\Views\Helpers\AbstractHelper
	public function FormatNumber ($number) { // $number = 1234.56;
		if ($this->request->GetLang() == 'fr') {
			return number_format($number, 2, ',', ' '); // french notation: 1 234,56
		} else {
			return number_format($number); // english notation: 1,234
		}
	}
}

Automaticly assigned protected properties

• AbstractHelper::$view as \MvcCore\View|\MvcCore\IView
• AbstractHelper::$controller as \MvcCore\Controller|\MvcCore\IController
• AbstractHelper::$request as \MvcCore\Request|\MvcCore\IRequest
• AbstractHelper::$response as \MvcCore\Response|\MvcCore\IResponse

Behaviour

• Your view helper will be created by static method GetInstance() as singleton with abstract class AbstractHelper.
• Everytime, when there will be rendered different view script (action view, layout view or sub-controller view), there will be called automatically method AbstractHelper::SetView($view); to setup view object or other objects inside helper to actual ones.
