RE: [SMARTY-DEV] feature request

Thanks for your input! Using method calls on objects is an option yes, but I don't prefer this: I don't want the template designer to get access to my objects. I think smarty plugins are way much better for this approach. I give to the template designer a set of functions (smarty plugins) which he can use, together with a small manual what the input parameters and return values should be.

To implement this in Smarty would probably require some work on the compiler, an alternative may be to use method calls on objects from within your templates: http://smarty.php.net/manual/en/advanced.features.php -- Mark Gibson <gibsonm@cromwell.co.uk> Web Developer & Database Admin Cromwell Tools Ltd.
