need help with executing own function

hi folks,

i've just started using smarty. i think its great but i do find some
difficulty adjusting to it. right now i'm stuck. i'm sure its quite a
simple one so please bear with me.

what do i need to do in smarty so that i can execute my own function
on a template var?

take a look at this situation.. let say in my template:
--begin code--
<td>Car Type: </td><td>{$car->car_type}</td>
<td>Displacement: </td><td>{$car->car_cc}</td>
--end code--

$car is being assign value from a db query result (car_type, car_cc
are table columns)

now, car_type are integers.. it does not contain the actual car type.
before i use smarty, this can easily done by creating a function to
translate the car_type to its respective type. ie: car_type 1 is for
sedan, car_type 2 is for hatchback etc etc.. like this
--begin code--
<td>Car Type: </td><td><?php echo getCarType($car->car_type) ?></td>
--end code--
with the function getCarType returning the actual car type.

but how do i do it (the getCarType function) now in the template with
smarty? fyi, all my functions are in one separate file.

tia,
zuhaimi

Don't. Pass an associative array of car types:

$types = array(
1 => 'Sedan',
2 => 'Hatchback'
);

and pass that to the template. Then, when you need the string version:

<td>Car Type:</td><td>{$types[$car->cartype]}</td>

That way you don't need to muck about with creating Smarty functions or
modifiers.
