How to get the current node id
vj0914 - June 19, 2008 - 14:55
I created a custom page, in the page I use php code as input format.
here is what I did:
<?php
global $node;
$node_id = $node->nid;
?>I thought this would give the nid of current node, but it apparently not, can any expert tell me how to do it? much appreciated.
the nid will depend on
the nid will depend on whatever the current node is, it's dynamically changing
Not available
It's not a global. I think your problem is that $node is not available in the context where the content is being evaluated.
no as the last post says the
no as the last post says the node object is not globally available! It really depends on what page you are trying to load the node object on, I think the easiest way to get the node id is to use the arg() function to find what is in the URL, eg:
for URL www.site.com/node/31
<?php
// return 'node'
print arg(0) ;
// return '31'
print arg(1) ;
?>
This also works for url aliases, as the arg() function uses the unmodified url path.
hope this helps.
for customizing breadcrumbs
Thanks all for replies to this post.
the reason I wanna get nid is to customize breadcrumbs on the page,
now I have 3 different page, client-1, client-2, client-3
under each page, I have different content which is clickable. What I want to do is to get nid of current content showing, and based on the nid of
current showing content, I can track back where this content comes from, e.g
Home>>client-1
Home>>client-2
Home>>client-3
this way viewers don't need to click "back" to go back to the previous page.
