custom template variable

[Pok4]

Hello,
i have this php function:

function get_from_db_config($val) {
	global $dbh;
	$get = $dbh->query("SELECT ".$val." FROM ".$_SERVER['DB_PREFIX']."config");
	$row = $get->fetch(PDO::FETCH_ASSOC);
	return $row[$val];
}

It is possible to have template variable (custom) to fetch data from table name -> column name, like this:
{{get_from_db | tablename | columnname}}
?

Something like that will be very good solution for me... I fetch mostly int values from columns, but sometimes there is a text too..
If you know a method or workaround to do that, i'll be very happy :)

it's not really idiomatic mustache to made database calls from the template. you should prepare your data before rendering, or use a viewmodel to encapsulate the logic.

Yes, im agree with you, but can you give me example with ready to use code ?

If is possible with something like this, will be ok for me.
