[TYPO3-english] Re: Extbase/Fluid extension: viewhelper to return associative array (T3 6.2.4)

[Hagen Gebauer]

Hi Joey,

thanks a lot! That's working brilliantly! Sometimes it's that simple :) Here's a short summary for everybody else to read:

The ViewHelper class:

namespace VendorName\ExtensionName\ViewHelpers;
class TestViewHelper extends \TYPO3\CMS\Fluid\Core\ViewHelper\AbstractViewHelper {
	/**
	 * @param $arrayIndex string
	 *
	 * @return string
	 */
	public function render($arrayIndex) {
		$returnArray = array('a' => 'abcdefg', 'b' => 'hijklmn');
		return $returnArray[$arrayIndex];
	}
}

calling an array element by its index in the Fluid template:
{namespace abc = VendorName\ExtensionName\ViewHelpers}
{abc:test(arrayIndex: 'b')} (calling by {namespace:viewhelper} and passing the array index)

will return:
hijklmn
