Question

In MS Dynamics CRM 4.0 we have created an extra tab for the salesorder entity in which an IFRAME with a custom, remote PHP page is loaded. Is there any way to find out which CRM user opened the tab with the IFRAME from the PHP file?

Answer 1

You should use postMessage to send the user’s information to the IFRAME. This works even if the IFRAME is on an other domain (cross domain). postMessage is supported in:

• Internet Explorer 8.0+
• Firefox 3.0+
• Safari 4.0+
• Google Chrome 1.0+
• Opera 9.5+
