For Joomla 1.5 do folowing steps:
Add new function to the end of
components/com_jshopping/lib/functions.php. Here is the code of the function:
function changeCategoryTextUsePlugin($category){
$mainframe =& JFactory::getApplication();
$dispatcher =& JDispatcher::getInstance();
JPluginHelper::importPlugin('content');
$obj = new stdClass();
$params = &$mainframe->getParams('com_content');
$obj->product_id = $category->product_id;
$obj->text = $category->description;
$obj->title = $category->name;
$results = $dispatcher->trigger('onPrepareContent', array (&$obj, &$params, 0));
$category->description = $obj->text;
return 1;
}
Call ths function in
/components/com_jshopping/controllers/category.php in
after
the line
$category->getDescription()
It must works.
