Symfony2：从控制器中的另一个文件获取HTML

Question

In my Symfony2 project, I would like to get the HTML of a file and put it in a variable in my controller.

I have a controller function like this:

public function myControllerAction()
{
   $htmlOtherFile = '';

   return $this->render('@MyBundle/myTargetFile.html.twig', ['htmlOtherFile' => $htmlOtherFile]);
}

The html file I would like to import is in my views folder: htmlOtherFile.html.twig

How can I get the HTML of this file into my $htmlOtherFile variable? I have already tried with file_get_contents , but without success.

Answer 1

all you need to do is call renderView from your controller on the template and put the contents in a variable.

$html = $this->renderView('/path/myTargetFile.html.twig', [/*options in here*/]);

Be sure to call renderView and not render on its own as that will return a Response instance, and not any HTML.

Alternatively, you can call:

$this->render('/path/myTargetFile.html.twig', [/*options in here*/])->getContent();

to return the html from the response.

Answer 2

如果是twig文件 - 你可以试试这个：

$this->renderView('/path/to/template.html.twig', []);

Answer 3

You can call a controller directly from you twig file if you want.

Use the syntax {{ render(controller('MyBundle:functionName')) }}
