Capture view output for preprocessing

I was in need of a way to wrap some HTML around view outputs, if
needed, thus stopping me from adding the wrapper code to the layout.
This was for a templating issue I was having.

So after spending some time looking through Cakes View class, I cam up
with the code below, hope it helps someone else.

<?php
class WrapperHelper extends AppHelper {

public function afterRender() {
$post = ob_get_flush();
while(ob_get_level() > 0) {
ob_end_clean();
}
$post = "
<div class=\"post\">
<div class=\"post-body\">
<div class=\"post-inner article\">
$post
</div>
<div class=\"cleared\"></div>
</div>
</div>
";
ob_start();
echo $post;
}
}
?>

What it does is this: capture the output buffer, clean all buffers,
modify the rendered view, start output buffering again and echo out
the modified view.

Puk!
