Properly implement hook_token_info() [#1192504]

I'm needing to get the title of a referenced node from within its parent so I can use autonodetitles module. Since Token module isn't working for fields in D7, I'm trying to do this by pulling fields out of the $node object. Here's the field I'm interested in, at $node->field_cal_event_parent

  [field_cal_event_parent] => Array
       (
           [und] => Array
               (
                   [0] => Array
                       (
                           [nid] => 59      //CAN GET THIS VALUE
                           [access] => 1
                           [node] => stdClass Object
                               (
                                   [nid] => 59
                                   [vid] => 59
                                   [type] => production_external_
                                   [language] => und
                                   [title] => Comedy Club    //CANNOT GET THIS VALUE
                                   [uid] => 1
                                   [status] => 1
                                   [created] => 1307347398
                                   [changed] => 1307348726
                                   [comment] => 1
                                   [promote] => 0
                                   [sticky] => 0
                                   [tnid] => 0
                                   [translate] => 0
                                   [uri] => Array
                                       (
                                           [path] => node/59
                                           [options] => Array
                                               (
                                                   [entity_type] => node
                                                   [entity] => stdClass Object
*RECURSION*
                                               )

                                       )

                               )

                       )

               )

       )

So the problem is that although I can get as far as the referenced node's nid using
$node->field_cal_event_parent['und'][0]['nid'];

I can't find the syntax for going one level deeper and getting the referenced node's title field.

While this code will work, it feels that I shouldn't need to load the referenced node just to get the title field:

$mynid = $node->field_cal_event_parent['und'][0]['nid'];
$mynode = node_load($mynid);
print $mynode->title;

Is there an easier way?

thanks

Title:	Best way to access title of referenced node within parent $node object	» Properly implement hook_token_info()
Version:	7.x-2.0-beta3	» 7.x-2.x-dev
Component:	Miscellaneous	» Code: node_reference
Category:	support	» bug

I would also like to use a token to access the node title. I have a field:

'field_name;

I expect to be able to access the referenced node title with the token:

[node:field-name:title]

but that is not working.

With devel and token installed on node/<n>/devel/token the field is showing up as:

[node:field-<referenced-content-type-machine-name>]

I tried:

[node:field-<referenced-content-type-machine-name>]
[node:field-<referenced-content-type-machine-name>:value]
[node:field-<referenced-content-type-machine-name>:title]

Nothing seems to work to get a token to access the node title of a referenced node.

Here is a first pass at node_reference_token_info() It is not working but I thought I'd upload it in case someone else wishes to continue where I left off.

This seems to be working in part. I can access the node reference with [node:field-name] You will need the Field Token patch along with this patch.

The patch makes node-reference fields appear in the Token UI's "Nodes" section. E.g. [node:field-contact] where "contact" is a node-reference field. In addition to this, a new section in the UI called "Node references" is created, which does not make sense in the context of a node-type settings form. This appears to be because of the extraneous plus character ("+") in the patch from comment #4. This character was noted in comment #6.

I removed the extra character from node_references.module and the "Node references" section disappeared.

I am still not sure how the [node:field-contact:field] and [node:field-values:?] tokens and sub-tokenswould be useful or what data they expose.

The attached annotated screenshot notes this same information.

The attached patch is the same as #4 but with the extra plus character removed.

I was able to use this patch to use the title of a referenced node as a token in an automatice nodetitle.

I think at a bare minimum, it would be a big step to just provide the Id's for the items being referenced. There is a token_function module, http://drupal.org/project/token_function , that you could use then pass those values into and process those into whatever info you needed.

Basic token fields are implemented in current token core module, but I need to add token for nid, as argument to Viewfield module of referenced field.

Current sulution [node:field-someone] return plain title of referenced module, but I need to get a NID of referenced module. Current version of Node references doesn't implement token for nid, or value.

So as original post of this issue, current situation is differencent, i dont'n need title but nid (original want title except of nid) ;-)
