Get content from a view and return a JSON

1

Hi guys,

simple ( apparently ) problem; I’d like to get content from a view, and return a JSON with that content.

Example:

 $response = $this->render($response, 'content.ajax', [
 'contentList'    => $contentList,
  ]);

return $response->withJson([
	'html' => $response->getBody()->__toString() , >>> horrible but works
]);

Is there another more elegant way to do this?

Thanks

Yes. you can use the fetch() function on twig instead which does not put it into the response object but rather gives you a string back.

In my controllers, my actions always return strings, which could be the result of a rendered twig template,
or a json result, or… you name it.

Still, I give you some weird example :wink:

 /**
     * Display the info
     *
     * @return string
     */
    public function info()
    {
        ob_start();
        phpinfo();
        $phpinfo = ob_get_clean();
        $phpinfo = str_replace('img {float: right; border: 0;}', '', $phpinfo);
        $phpinfo = str_replace('a:link {color: #009; text-decoration: none; background-color: #fff;}', '', $phpinfo);

        return $this->view->render($this->response, $this->templateDir . '/info.twig', ['phpinfo' => $phpinfo]);
    }

My twig (the usefull part)

{% set title = 'Info' %}
{% extends common ~ 'layoutmain.twig' %}

{% block content %}
{{ phpinfo | raw }}
{% endblock %}
