How to verify a user in a user group?

Hi,

I 'm creating a custom login page to access a site, for that how I can verify the user exists in a user group?

The Portal Development Guide has some example code that will help you do this. Starting in Chapter 14, you'll find details on autheticating users and finding the user groups. On page 267 you'll find a good synopsis of getting attributes of a user and then finding user groups. You can also see information here on how to add business logic to this process (for finding a specific group membership for example).

For example, you can get information about a user through the PortalContext object (in a java class) and use EntityType to get things like group membership. Here is an example class that gets the entity object "currentName" for a user.

 

public PortalURI execute(PortalContext portalContext) throws ActionException {

HttpServletRequest request = portalContext.getHttpServletRequest();

 

String name = (String) request.getSession().getAttribute("currentName");

request.setAttribute("currentName", name);

 

return null;

 

or in a script as: User user = portalContext.getCurrentUser(); to get the current logged on user.

 

once you have the user then you need to get the list of entities available to that user:

 

 

// get users entities

EntityType userType = currentUser.getEntityType();

 

// query the type to get the ID of the property

Set propertyIDs = userType.getPropertyIDs();

 

// get the value of this property

String firstName = (String)currentUser.getProperty("firstname");

 

// check the value of this property attribute

 

EntityProperty firstNameProperty = userType.getProperty("firstname");

boolean canSearch = firstNameProperty.isSearchable();

 

// Then you can use the Group Type to find all the groups for this user or to look for a specific group...

 

EntityType userGroupType = UserGroupManager.getInstance().getUserGroupEntityType();
try{
Set userGroups = currentUser.getParents(userGroupType, false);

}catch (EntityPersistenceException exception){

// Handle exception.

}

try{

boolean isMember = currentUser.hasParent(groupA, false);

}catch (EntityPersistenceException exception){

// Handle exception.

}

 

 

Most of this is from the Dev Guide but I added some practical examples as well (since the dev guide tends to be a bit pedantic).

 

Hope this helps.
