weird template include problem

I found a weird template include problem, ill try to explain whats going on.

i have reproduced it on
https://www.vaultwiki.org/demo/TestArjan?redirect=no

I have a template, lets say: [template]seperator[/template]
When i use this in a page to seperate text, everything goes well. (first display on TestArjan)

When i include it in a template, all goes well (third display on TestArjan)

BUT
When a template already HAS a template include (see seccond display on TestArjan) the seccond template include gets ignored??
(many many of my templates and templatecalls have other templates included..)

Okay, took me a while to figure this out, but it's not that the template includes another template. It's that a template is passed as a parameter into another template. I thought this was supported a while back, but it looks like some vulnerability patches broke the functionality.

What happens is that only the current template level is checked for replacements. In this case the passed templates are resolved in level 1, but they are included in level 2, and the replacement can't occur in level 2 because it was already registered for level 1. In order to fix this, we need to find the template instance by searching the current and upper levels in reverse (still reject templates from a deeper level). Also, we need to modify the way template instances are numbered internally to prevent collisions across levels.

In vault/class/bbcode/template.php, find:

Code:

if (!isset($threadinfo['templates'][$this->parser->recursion['template'] - 1]["$match[1]"]["$match[2]"]))

Replace with:

Code:

$args = $this->get_instance($match[1], $match[2]); if ($args === null)

Find and remove:

Code:

$args = $threadinfo['templates'][$this->parser->recursion['template'] - 1]["$title"]["$match[2]"];

Find:

Code:

function validate_recursion($set, $find)

Add before:

Code:

function get_instance($title, $pos) { global $threadinfo; $i = $this->parser->recursion['template'] - 1; for ($c = $i; $c > -1; $c--) { if (isset($threadinfo['templates']["$c"]["$title"]["$pos"])) { return $threadinfo['templates']["$c"]["$title"]["$pos"]; } } return null; }

In vault/class/bbcode.php, find:

Code:

$instance = count($threadinfo['templates'][$this->recursion['template']]["$templatelow"]);

Replace with:

Code:

static $template_count; $template_count["$templatelow"]++; $instance = $template_count["$templatelow"];

when changing the code like above, my live server doesnt include the template tables anymore, and on localhost it does not seem to work.
I have noticed by previous fixes as well.. wondering why the fix didnt work, and uploaded the new build.. and tadaaa

this is not a showstopper for me, so it can wait untill next build
