I found this message on php-general list, and I'm cross-posting the
reply to Smarty list.
I see a couple of issues with passing Smarty object to modifiers.
1. You want to use _current_file and _current_lineno member variables,
but they are only defined in Smarty_Compiler class, and what actually
runs the modifiers is Smarty class. Check Smarty::_run_mod_handler().
2. The only reasonable way to make Smarty object available to modifiers
is to pass it as a last parameter. However, you run into problems when
your modifier has default parameters. For example:
function x_mod($arg1, $arg2 = 5, &$smarty)
{
...
}
If you call modifier as {$foo|x}, $arg2 would actually point to the
Smarty object, and you will get a notice complaining about $smarty
parameter not being passed. So, it would not be possible to use default
parameters for modifiers which is a big step back IMO.
Can you provide alternative ideas?
