[TYPO3-mvc] Date examples, can't find any.

[Nathan Lenz]

We need a viewHelper repository. :)

Here is a simple viewHelper that allows the Form_TextboxViewHelper to
work with a DateTime method.




<myext:datetextbox property="published" format="d-m-Y"></myext:datetextbox>



class Tx_Myext_ViewHelpers_DatetextboxViewHelper extends
Tx_Fluid_ViewHelpers_Form_TextboxViewHelper {

	
	/**
	 * Initialize the arguments.
	 *
	 * @return void
	 */
	public function initializeArguments() {
		parent::initializeArguments();
		$this->registerTagAttribute('format', 'string', 'The format to render
the date in.');
	}

	/**
	 * Renders the textbox.
	 *
	 * @return string
	 * @api
	 */
	public function render() {
		$name = $this->getName();
		$this->registerFieldNameForFormTokenGeneration($name);
		
		$this->tag->addAttribute('type', 'text');
		$this->tag->addAttribute('name', $name);
		
		/** @var DateTime */
		$value = $this->getValue();		
		$stringValue = $value->format($this->getFormat());
		
		$this->tag->addAttribute('value', $stringValue);
		
		$this->setErrorClassAttribute();
		return $this->tag->render();
	}
	
	/**
	 * Get the format that was passed into the tag
	 * @return string Date format compatible with date()
	 */
	protected function getFormat() {
		return $this->arguments['format'];
	}

}
