I have a node named let's say "group" to which I added a field called "foo".

How would I programmatically give a value to this "foo" attribute?

I would like to do this when a user is joining a group. This joining process does not involve a saving of the current node, it just add data to a custom table i made. So Hooks don't apply here.

I am guessing i would have to:

1-load the node 2- add data to my attribute 3- resave the node

I am still trying to figure out how to do that, so if anyone has experience to share that'd be much appreciated..

Thanks

Actually very straight forward, here is how i have done it: 

$group = node_load ( $nid );
$group-> foo = 'bar';
node_save ($group);

That's it.

Hope that' ll help anyone.

You have a lot of different hooks you can use to edit the node with. See Node API Hooks for more information on those.

I would personally use hook_node_presave() to add a value to "foo" this will then be added to the node before it's saved to the database.

  • Thanks for your answer Digital, although using hook would mean that i am already in a node editing process. What i would like to achieve is a snipet of code that would load a node in the background, add a value to one of it s attribute and then save it .

  • It that case you'll need to use the hooks for loading the node and then saving it. All this would need to be packaged into a custom module.

  • Thanks for the input, though the process doesn't involve any hooks at all. Just simple node load and node save, see below
