Using halt() within a function in template file

[Ivan Gretsky]

Good evening (at least in my part of the world)!

Is there a way to call halt() method from within a function in a template file?

[rick]

$this->halt();
As shown at the bottom of this thread.

Is this what you are referring to?

[Ivan Gretsky]

Yes, that is what I need to do. But in a function, where $this (which contains current template) is out of scope.

Hm... For whatever reason the halt() method is protected and can therefore only be called from within the class or derived ones. Passing $this to the function does not work and I don't know of any solution other than using die() or exit() in this case. Or just let the function return false and halt outside in that case:

function foo() {
  if(...) return false;
  echo 'foo bar';
}

if(foo() === false) return $this->halt();

echo 'something more';

Thanks @bernhard! I did try about the same tricks to make it work and ended up just doing

exit(0);

There's no way to halt a template rendering from within my custom module's ready method?  return $this->halt(); doesn't work ?

[Jonathan Lahijani]

How would I halt output of a template file using return $this->halt(); but with that code not actually appearing in the template file itself?

In short, I want to halt output of a template file at some point using the halt method described, but I want to have it be done more flexibly, meaning I want that code to exist within my ready.php for example (or just somewhere not in the template file).  What's the best way to do this?

I don't want to use exit because it has unintended consequences.

I think your question totally depends on how you have built your frontend. When using RockFrontend for example you could hook into RockFrontend::render() and then trigger the halt() before or after any portion of code has been rendered.
