1 node_access_test.module | node_access_test_page() |
Page callback: Creates the node access test page.
Page should say "No nodes" if there are no nodes, and "Yes, # nodes" (with the number filled in) if there were nodes the user could access. Also, the database query is shown, and a list of the node IDs, for debugging purposes. And if there is a query exception, the page says "Exception" and gives the error.
