I am thinkig of using smarty for my gallery script (http://singapore.sf.net) but I have a question:

My script uses functions which generate content on request to display on the page. Is it possible to do this with Smarty? I don't want to blindly assign the output of these functions to variables because then even content which is not displayed on that page will still have to be generated. I equally don't want to create a plugin for each function because there are many and they depend on each other.

I just want to be able to write {something} and that be replaced by the result of running something()

T.

You might want to consider using Smarty assigned objects. Since an object can expose many functions, it is similar to what you want. Otherwise, you can also explicitly register functions with Smarty, but they must support the Smarty calling and return interfaces. Why, you can even create a single generic function that supports the Smarty interface but then delegates to your custom functions based on a passed parameter from the template.

Smarty is EXTREMELY flexible.

See: http://smarty.php.net/manual/en/advanced.features.php

and http://smarty.php.net/manual/en/plugins.php

EDIT:

Lastly, Smarty is probably overkill in this situation. You can probably get away doing a custom regex if all you need is textual replacement. If you STILL want Smarty, you can custom regex in a pre-filter.

Perhaps on a side-note: your application code should be responsible for generating the right amount of data for your templates instead of delegating that to your template code.
