[drupal-support] $node not always available
I recently asked for a way to know the current viewed node, someone point me to global $node. The problem is that the variable is randomly available, sometimes it have the correct content, sometimes is empty. This is probably a bug of Drupal core. I'm using CVS HEAD. I'm thinking using global $_menu['local tasks'] and do some tricky parsing to find out the current viewed node. My goal is to have selectively content shown in themes based on the owner of the current viewed node, that's why I inevitably need to know the current node. Thanks in advance for any hint.

Well, if you are not viewing a node, $node is not available, or incorrect. Does that hlep you? Regards, Bèr -- [ Bèr Kessels | Drupal services www.webschuur.com ]

No, this is by design. $node is not a global variable.

You can parse the url instead (arg(0) == 'node' && is_numeric(arg(1))). Cheers, Gerhard

You can parse the url instead (arg(0) == 'node' && is_numeric(arg(1))).
Additionally .. you can retrieve the node using node_load (it caches internally.. ) so if ((arg(0) == 'node') && is_numeric(arg(1))) { $node = node_load(array('nid' => arg(1)); } will populate the node variable. - -- Adrian Rossouw Drupal developer and Bryght Guy http://drupal.org | http://bryght.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (Darwin) iD8DBQFCeOZ1gegMqdGlkasRAk56AKCTwdKpP04LuDIA1GivdWI6EitQdACfd8lt M7HMHJeUEPQBHQpqrv02sSc= =T5jD -----END PGP SIGNATURE-----
