Ca c'est la fonction qui chie apparemment dans la page Smarty.compiler.class.php:

Code :

function _compile_custom_tag($tag_command, $tag_args, $tag_modifier, &$output)
    {
        $found = false;
        $have_function = true;

        /*
         * First we check if the custom function has already been registered
         * or loaded from a plugin file.
         */
        if (isset($this->_plugins['function'][$tag_command])) {
            $found = true;
            $plugin_func = $this->_plugins['function'][$tag_command][0];
            if (!is_callable($plugin_func)) {
                $message = "custom function '$tag_command' is not implemented";
                $have_function = false;
            }
        }
        /*
         * Otherwise we need to load plugin file and look for the function
         * inside it.
         */
        else if ($plugin_file = $this->_get_plugin_filepath('function', $tag_command)) {
            $found = true;

            include_once $plugin_file;

            $plugin_func = 'smarty_function_' . $tag_command;
            if (!function_exists($plugin_func)) {
                $message = "plugin function $plugin_func() not found in $plugin_file\n";
                $have_function = false;
            } else {
                $this->_plugins['function'][$tag_command] = array($plugin_func, null, null, null, true);

            }
        }

        if (!$found) {
            return false;
        } else if (!$have_function) {
            $this->_syntax_error($message, E_USER_WARNING, __FILE__, __LINE__);
            return true;
        }

        /* declare plugin to be loaded on display of the template that
           we compile right now */
        $this->_add_plugin('function', $tag_command);

        $_cacheable_state = $this->_push_cacheable_state('function', $tag_command);
        $attrs = $this->_parse_attrs($tag_args);
        $_cache_attrs = '';
        $arg_list = $this->_compile_arg_list('function', $tag_command, $attrs, $_cache_attrs);

        $output = $this->_compile_plugin_call('function', $tag_command).'(array('.implode(',', $arg_list)."), \$this)";
        if($tag_modifier != '') {
            $this->_parse_modifiers($output, $tag_modifier);
        }

        if($output != '') {
            $output =  '<?php ' . $_cacheable_state . $_cache_attrs . 'echo ' . $output . ';'
                . $this->_pop_cacheable_state('function', $tag_command) . "?>" . $this->_additional_newline;
        }

        return true;
    }

apparemment le $have_function n'existe pas d'où la syntax_error

ce qui est étrange aussi, c'est quand rafraichissant la page, le message d'erreur disparait mais la page ne présente aucune trace de l'UDT, comme si elle n'était pas appelée.
