how to find whether a node has more than one revision? How could I find whether a node has more than one revision. I use node_load($nid) and get a $node object.
How can I achieve this using the object? What would be the best way to do it?
Have you checked node_revision_list($node) function?


  This returns a list of all the existing revision numbers.


You can pass the current node and it will return list of all revisions.
