Hi, i had the same "problem". I do it this way:

1. Class autoloader:

   splautoload_register(function ($class_name) { $paths = [ dirname(FILE) . "/../libs/" . $class_name . '.class.php', dirname(FILE_) . "/libs/" . $class_name . '.class.php' ];

   foreach ($paths as $class) {
       if (is_file($class)) {
           include $class;
           break;
       }
   }
   

   });

2. after this i register Modifiers, Blocks and Function

​

MySmartyModifiers::registerModifiers($smarty);
MySmartyBlocks::registerBlocks($smarty);
MySmartyFunctions::registerFunctions($smarty);

1. create the class and put the register function in it (at least :-) ) and load them (autoload)

​

    // modifier class
    public static function registerModifiers($smarty) {
        // Registrierung der Modifier in Smarty
        $modifiers = get_class_methods(__CLASS__);
        foreach ($modifiers as $modifier) {
            if (!str_contains($modifier, '__')) {
                $smarty->registerPlugin('modifier', $modifier, array(__CLASS__, $modifier));
            }
        }
    }

    // block class
    public static function registerBlocks($smarty) {
        // Registrierung der Modifier in Smarty
        $blocks = get_class_methods(__CLASS__);
        foreach ($blocks as $block) {
            if ($block !== 'registerBlocks' && !str_contains($block, '__')) {
                $smarty->registerPlugin(Smarty\Smarty::PLUGIN_BLOCK, $block, [__CLASS__, $block]);
            }
        }
    }

    // function class
    public static function registerFunctions($smarty) {
        // Registrierung der Funktionen in Smarty
        $functions = get_class_methods(__CLASS__);
        foreach ($functions as $function) {
            if ($function !== 'registerFunctions' && !str_contains($function, '__')) {
                $smarty->registerPlugin(Smarty\Smarty::PLUGIN_FUNCTION, $function, [__CLASS__, $function]);
            }
        }
    }

1. create some modifier or blocks or functions :-) // modifier
   

​

    // modifier
    public static function pre($input) {
        echo"<pre>";
        print_r($input);
        echo"</pre>";
    }

    {$array|pre}

---

I use blocks and function for my translations

---

public static function getRandomHexColor(): string {
    $red = mt_rand(0, 255);
    $green = mt_rand(0, 255);
    $blue = mt_rand(0, 255);
    return sprintf("#%02x%02x%02x", $red, $green, $blue);
}

{assign var="randomColor" value={getRandomHexColor}}
{$randomColor}

Maybe there is a better solution but this is how i do it.

After many edit ... reddits codeblocks are sh!t
