[TYPO3-dev] Re: Register namespace for ViewHelpers

[Daniel Haring]

Hi Jens,

you should be able to achieve this by extending the Template Parser.



~/typo3conf/ext/myext/Classes/Parser/TemplateParser.php:

[php]
<?php

namespace Vendor\Myext\Parser;

class TemplateParser extends \TYPO3\CMS\Fluid\Core\Parser\TemplateParser{

    public function __construct() {
        $this->namespaces = [
            'f' => 'TYPO3\\CMS\\Fluid\\ViewHelpers',
            'myns' => 'Vendor\\Myext\\ViewHelpers'
        ];
        parent::__construct();
    }

    protected function reset() {
        $this->namespaces = [
            'f' => 'TYPO3\\CMS\\Fluid\\ViewHelpers',
            'myns' => 'Vendor\\Myext\\ViewHelpers'
        ];
    }

}
[/php]



~/typo3conf/ext/myext/ext_typoscript_setup.txt:

[code]
config.tx_extbase.objects{
    TYPO3\CMS\Fluid\Core\Parser\TemplateParser{
        className = Vendor\Myext\Parser\TemplateParser
    }
}
[/code]



After this (and clearing caches), you should be able to call your ViewHelpers via '<myns:myviewhelper />' without the need of specifying your namespace within every template.

Tested in TYPO3 CMS v 7.6.0 LTS.

Cheers,
Daniel
