h1. Developing a module or plugin for VirtueMart Virtuemart 2 When you want to develop your own extension for VirtueMart, virtuemart, then these this hints should you help you 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::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 Loading and instancing a model is very easy in Vm, just use $mynameModel = VmModel::getModel('myname'); for example: $currencyModel = VmModel::getModel('currency'); When you want to access the js used in vm then load them with @$config->jQuery(); $config->jVm();@ or for the css use @$config->cssSite();@ *adding Virtuemart 2 menu to your component* IN view.php.html use ----------------------------- if(!class_exists('VmView'))require(JPATH_VM_ADMINISTRATOR.DS.'helpers'.DS.'vmview.php'); class vmg_exportViewCategory extends VmView ----------------------------- in tmpl/default.php for eg. before your HTML codes ----------------------------- @$lang = JFactory::getLanguage(); $extension = 'com_virtuemart'; $base_dir = JPATH_ADMINISTRATOR; $lang->load($extension, $base_dir); AdminUIHelper::startAdminArea();@ ----------------------------- After your HTML codes ----------------------------- @ AdminUIHelper::endAdminArea(); @ ----------------------------- * in controllers if model are wanted* @ if(!class_exists('VmModel'))require(JPATH_VM_ADMINISTRATOR.DS.'helpers'.DS.'vmmodel.php');@ @ $model = VmModel::getModel($this->vmView);@ or you can use @function vmModel($model=null){ if(!class_exists('ShopFunctions'))require(JPATH_VM_ADMINISTRATOR.DS.'helpers'.DS.'shopfunctions.php'); return ShopFunctions::getModel($model);@ *to use vm2 tables* @JTable::addIncludePath(JPATH_VM_ADMINISTRATOR.DS.'tables');@ For shipment, payment, or other plugin development please look here [[Plugin system]] or for modules here [[Modules system]]
