I am coding a system for my bachelor theses. And I had & solved a small problem.

The problem. I have to types of content types – Record and Group of Records. If I navigate to Group of Records there should be a block with a link saying “Create a record”. The problem is that I need to pass some additional argument to the form Record (the node ID of Group of Records). So, my link looks like that: node/add/record?groupid=1001. The question: how to get the node ID of Group of Records?

The solution: small if()

if ( arg(0) == ‘node’ && is_numeric(arg(1)) ) {
$node = node_load(arg(1));
// Your code here…
}
