OPTv2: loading a view from DB instead of file

[anw]

Hi,

First of all, congratulations for your incredible work. I'm really impressed, this project looks extremely well designed, coded and documented.

I'm in charge of a multilingual wiki engine based on XML contents, which are stored in database.
In order to allow a few dynamic operations in wiki contents (loops, conditions, external contents fetching and inclusions...) I implemented a basic XML-based logic syntax.
Unfortunately this is a quick&dirty work, and I need something more powerful.

It seems that OPTv2 would feet my needs without too much overhead, for handling wiki's dynamic contents parsing/rendering. However, OPT seems designed to handle XML-templates read from the file system only :

Code:

$view = new Opt_View('example.tpl');

I wonder how hard it would be to allow constructing a view directly from a template-content (and eventually giving a name to identify it - and retrieving it from cache) ? Maybe something like this :

Code:

$view = new Opt_View($wikiPageName);
if (!$view->cacheExists()) {
$view->setContent($wikiPageContent);
}

Do you think it's something possible, without too much hacks ? Is Opt_View the only class reading template from file system, or may it be done in other places too ?

Thanks in advance, and keep up great work!

Hi! Thanks for your words, we are glad you like OPT2.

OPT2 supports different sources for templates without any hacks. You just have to register a new stream in php:
http://docs.php.net/manual/en/book.stream.php
and then use it in Opt_View.

An example of stream usage can be found in "dev" files on our SVN:

Wow, this is great news, I'll try in this way! Thanks for the quick answer.
