Hi there,

Hope someone can help me. I have a class called "article" with 7 attributes. Already created few objects of this class and now i want to add another couple of new attributes to the class.

Any suggestions what I can do so that old objects of the class get also effected with default values of the new attributes.

Cheers
Smith

You will need to use a custom PHP script for this. Script will update all existing content objects with new attribute.

Access to PHP command line is needed.
