 |
|
Hi,
I'm pretty new to Smarty3.
This confuses me:
| Code: |
class SmartyVerbose extends Smarty
{
function __construct()
{
parent::__construct();
echo "I'm born\n";
}
function __destruct()
{
echo "I'm dead\n";
parent::__destruct();
}
}
$smarty = new SmartyVerbose();
$smarty->fetch('a.tpl');
|
dies twice:
| Code: |
I'm born
I'm dead
I'm dead
|
this is 'cause the cloning in method createTemplate() (Smarty.class.php:446)
this is really necessary?
I'm little tangled in parent-child relationship between Smarty and Templates.
Can someone explain to me? |

Smarty's __destruct() does exactly nothing (besides being defined):
| Code: | /**
* Class destructor
*/
public function __destruct()
{
} |
not sure how this could lead to the problems you described. Is it possible, that there are 2 instances? one of them being a clone (and thus not having __construct() invoked)? |

ok... should've read all of it.
Smarty 3.0.6 and current SVN trunk both clone the Smarty object. This is not only unnecessary, but potentially wrong. The issue has already been addressed in the rodneyrehm branch (which is our playground for Smarty 3.1). |

This problem is fixed in the SVN trunk version (globe was wrong about this).
The cloning of the Smarty class is no longer done on the internal createTemplate calls.
However if you create template objects manually in your script it will still clone the Smarty class to enable the possibillity to modifiy Smarty properties just for that template. |
