Slidehorizon optimierung: Call to a member function get()...
Hallo Forum
Ich versuche das Modul Slidehorizon etwas zu optimieren. Der erste Schritt dabei ist, das Javascript auszulagern, damit der Javascriptcode den Quelltext nicht mehr verwüstet.
Nun habe ich den JavaScript erzeugenden php Code in ein neues File namens js.css verschoben und in diesem File die Datei helpers.php included. Wenn ich nun die Seite js.php im Browser aufrufe, erscheint lediglich die Meldung "Fatal error: Call to a member function get() on a non-object in /joomla15/modules/mod_slidehorizon/js.php</b> on line <b>10"
Weiss jemand wie ich das beheben kann?
Hier der Code der drei Dateien, die alle im selben Verzeichnis liegen:
mod_slidehorizon.php:
js.php:PHP-Code:<script language="JavaScript" type="text/javascript" src="modules/mod_slidehorizon/js.php"></script>
helper.php:PHP-Code:<?php

$php_direction = ($params -> get('direction','left')); // direction of scrolling
$php_contwidth = intval ($params -> get('bwidth',0)); // width of outer container-border
$php_contcolor = ($params -> get('bcolor','FFFFFF')); // color of container and gap, if any
$php_gap = intval ($params -> get('gap',0)); // size of gap
