Hi,

new to smarty and not sure I am getting it right. I'm using 3.0b6.

A class:
Code:

class Object {

  function method($string) {
    return md5($string);
  }

}


Register the object:
Code:

$smarty->register_object('obj', $object, NULL, FALSE, NULL);


Try to pass it a POST variable:
Code:

{obj->method p1=$smarty.request.var}


When processing I get this from PHP:
Code:

PHP Warning:  md5() expects parameter 1 to be string, object given


So it seems what is passed back to my method is a Smarty object and not the value of the POST variable.

Is this normal? How do I pas the value?

thanks

Luca

There was a bug in the handling of the format parameter of the register_object method.

This is fixed in the SVN now.


Note that instead of using register_object you can also assign objects as Smarty variable.

Code:
$smarty->assign('obj',$object);


Template
Code:
{$obj->method($smarty.request.var)}

Oh, good, I'll retest soon.

By the way, is there any advantage in assign_by_ref over assign? I guess assign_by_ref avoids copying the object over.

Also by assigning the object instead of registering it I think the ability to restrict methods accessible from the templates is lost.

thanks

There is no advantage of assign_by_ref for objects as in PHP5 objects are always handled as reference.

You are right, if you assign objects you can't restrict the access to methods.

Great to know.

I guess, not even by prefixing methods with _ since this is just a reference.
I like the cleaner syntax of assigned objects, and maybe from a security pov is also better to know any method in an assigned class is accessible to the templates, so just don't put it there.
