And solutions like
$nid = $node->nid;
don't work in my custom module (though I'm told they work in templates?). No error or anything, it just instantiates
$node with a
It feels like there must be something really obvious that I'm missing.
So, how do you get the NID of the current node without a template, while following best practices and building a reasonably robust module?
