How to cache a modified view?

[eluser]gminuses[/eluser]
I try to compress my view and then cache it like this:

Code:

class MyController extends Controller {
    function myMethod() {

        $html = $this->load->view('myview', '', true);

        compressHtml($html);

        $this->output->cache(1);

        echo $html;
    }
}

But the user guide said

caching will only work if you are generating display for your controller with a view.

So how can I trigger a caching after processing the output?

I use a custom caching helper: http://ellislab.com/forums/viewthread/127155/

Could you just pass your compressed html into another view and output it through that? Then I think it would be cached?

Code:

class MyController extends Controller {
    function myMethod() {

        $html = $this->load->view('myview', '', true);
        $html = compressHtml($html);

        $this->output->cache(1);

        $this->load->view('output', array('html'=>$html));

    }
}

Inside views/output.php just <?php echo $html; ?>

It's kind of a hackish way to accomplish this but would allow you to use the native caching library (i think).

To clooner:
It seems to be a little overkill, but If I'm running out methods, I'll try that. Thanks.


To louis w:
This might not be a solution. If I have multiple html files to be compressed, I'll have to create this kind of view for every single of them, which is tedious and unmaintainable. Anyway, thanks for the reply.

Couldn't you just use the same output view for all the pages? All it's doing is echoing what you feed it.

[eluser]louis w[/eluser]
Have you also tried instead of your original echo? I don't use the CI cache mechanism but it looks like this might work because it get's written with the output->_display method.

$this->output->set_output($html);

I thought if I use same view for all pages, once it got cached, the following pages won't be displayed, because the view is already cached. Now I figure I might be wrong?

This works like a charm, Thanks!
