Hey there.
"{returnValue.a}" would be the correct call, since the view helper Anja
suggested introduces that exact variable name.
You would need to call it like this
> <namespace:test>
> <h1>Test: {returnValue.a}</h1>
> {returnValue -> f:debug()}
> </namespace:test>
That's basically what the forViewHelper does for each iteration, it introduces
a new variable which is named according to the string given as "as" argument of
the forViewHelper. You skipped that "as" argument and used always "returnValue".
Another idea would be to create that "return $array" view helper you posted in
your first mail and use this one inside an "alias" view helper
> <f:alias map="{returnValue: '{namespace:test()}'}">
> <h1>Test: {returnValue.a}</h1>
> {returnValue -> f:debug()}
> </f:alias>

Betreff: [TYPO3-english] Re: Extbase/Fluid extension: viewhelper to return
associative array (T3 6.2.4)
Hi Anja,
thanks a lot for your reply. But somehow it doesn't work although there isn't a
parsing error at least :) calling {returnArray.a} returns an empty string
{namespace:returnArray.a} or {namespace:test.returnArray.a} instead are not
being parsed but displayed as is.
(the class is called TestViewHelper that's why I tried to call
namespace:test...)
Here is the full class:
class TestViewHelper extends
\TYPO3\CMS\Fluid\Core\ViewHelper\AbstractViewHelper {
/**
*
* @return array
*/
public function render() {
$returnArray = array('a' => 17, 'b' => 42);
$this->templateVariableContainer->add('returnArray', $returnArray);
$output = $this->renderChildren();
$this->templateVariableContainer->remove('returnArray');
return $output;
}
}
Cheers,
Hagen.
