You just need to get the nid of the main node into the creation of the
subordinate node typoes. How about using a query string to specify the
parent, like<br>
<br>
node/add/B?mainnode=(nid of A)<br>
<br>
or maybe<br>
<br>
node/add/B/(nid of A)<br>
<br>Populate the new field in hook_form(). You can even choose to show an input control for the field if it's not specified<br>

Hello, folks,<br>&nbsp; I'm in need of a little help...<br>&nbsp; I have a module with 3 types of node. Node A, B and C.<br>&nbsp;
I am trying to do something like A is the main node and B &amp; C
references A. So that, when I show the node A (teaser or full node), I
get some informations about nodes type B and C that makes reference to
A.
<br>&nbsp; Also, I want to node types B and C have a reference to the parent (A).<br>&nbsp;
When the user inserts the data, it must be transparent to him as who
the parent is (like there is a link on node type A that allows the user
to create type B or C and the node creation page will not ask the user
who the parent is). The only creation method shoud be like this for
nodes B and C (there should not have a link on the node creation list.
Just for type A)
<br><br>&nbsp; I took a look at the project module, but I couldn't get much out of it...<br>&nbsp; Any help is appreciated...<br><br>Thanks,<br>- Luis Sergio Moura<br>
