Is there an way to access smarty variable in the {php} {/php} block? I've glance through the FAQ and Smarty Doc, but couldn't find an answer. One ugly way is to use the SESSION variable, but that defeats the purpose of using smarty variable.

Thanks for the help,
Scott Seong

$this works...

To be exact, I had to use $this->_tpl_vars['variable'].

Thanks much!
Scott

even cleaner would be
$var = $this->get_template_vars('variable');

if you want to change those variables obtain a reference:
$var = &$this->get_template_vars('variable');

see:

@messju: is there a reason that a reference isn't always returned by get_template_vars?

@boots: the reason is simply that it is not possible in php. the function returns a reference, but the '='-operator performs a copy. you allways have to request a reference explicetly with the &-operator in the assignment.

of course, doh. Sorry!!

I think I've gotten very used to using static classes where I pass by reference the object that I want filled (or molded) with the function results. ( eg: myclass::getvars( $myvarobj, $var ); ) This avoids the usual trickery involved with PHP return types and assignment and for me, helps me separate my data and purely functional classes. In fact, I usually setup the function return values to be either True/False or an integer return code.

As always thanks for the reply and setting me straight!
