h1. Developing a module or plugin for Virtuemart 2 When you want to develop your own extension for virtuemart, then this hints should you help to get started: Use @if (!class_exists( 'VmConfig' )) require(JPATH_ADMINISTRATOR.DS.'components'.DS.'com_virtuemart'.DS.'helpers'.DS.'config.php');@ to load the configuration object in your extension. Then use @$config = VmConfig::getInstance();@ @VmConfig::loadConfig();@ to load the configuration values, you can then easily access them with @VmConfig::get('yourVariable','default');@ After loading the VmConfig you should always use the vm path constants to access files @JPATH_VM_SITE = JPATH_ROOT.DS.'components'.DS.'com_virtuemart' ); JPATH_VM_ADMINISTRATOR = JPATH_ROOT.DS.'administrator'.DS.'components'.DS.'com_virtuemart' );@ For performance reasons you should always use the @if (!class_exists( 'MyClass' )) require (JPATH_VM_ADMINISTRATOR.DS....)@ construction, dont use require_once When you want to access the js used in vm then load them with @$config->jQuery(); @VmConfig::jQuery(); $config->jVm();@ VmConfig::jPrice();@ or for the css use @$config->cssSite();@ @VmConfig::cssSite();@ For shipment or payment plugin development please look here [[Plugin system]] for modules here [[Modules system]]
