How to call a php function inside a smarty .tpl file?

Hi i have written a function in .php file. i.e.

public static function getCategories($id_lang = false, $active = true, $order = true, $sql_filter = '', $sql_sort = '',$sql_limit = '')
{
if (!Validate::isBool($active))
die(Tools::displayError());

$result = Db::getInstance(_PS_USE_SQL_SLAVE_)->ExecuteS('
SELECT *
FROM `'._DB_PREFIX_.'category` c
LEFT JOIN `'._DB_PREFIX_.'category_lang` cl
ON c.`id_category` = cl.`id_category`
WHERE 1 '.$sql_filter.' '.($id_lang ? 'AND `id_lang` = '.(int)($id_lang) : '').'
'.($active ? 'AND `active` = 1' : '').'
'.(!$id_lang ? 'GROUP BY c.id_category' : '').'
'.($sql_sort != '' ? $sql_sort : 'ORDER BY c.`level_depth` ASC, c.`position` ASC').'
'.($sql_limit != '' ? $sql_limit : '')
);

if (!$order)
return $result;

$categories = array();
foreach ($result AS $row)
{
$categories[$row['id_parent']][$row['id_category']]['infos'] = $row;
}
return $categories;
}


and i want to call this function inside a .tpl file. I used
{php} {/php}
way,but this not works.
What is the way to call this one?

Thanks

Answer

Smarty is a templating language - if you want to output the results of a function, assign the output to a smarty variable

$smarty->assign('categories', getCategories($args));

And then use it in your template

{$categories}

There are very few situations where this isn't the correct pattern.
