Do you need to insert an IFrame within your portal and you want to pass some information to your external script? 

Now you can do it by installing IFrame Scoped Hook on your portal. Let's see how to do that.

First you need to download and install the hook from Liferay Marketplace: IFrame Scoped.

This hook overrides the standard behaviour of the IFrame core portlet by adding 3 new configuration parameters:

companyId

ID of the current company

groupId

ID of the current group

userId

ID of the current user

Once enabled the options you want, the IFrame core portlet will ad to the URL the parameters above in order to be managed in the external script.

The extension is available on the Liferay Marketplace: IFrame Scoped
