The Node Reference URL Widget module adds a new widget to the Node Reference
CCK field type. It auto-populates a node reference field with a value from the
URL, and does not allow this value to be changed once set.

Node Reference URL Widget was written by Nate Haug.

Dependencies
------------
* Node Reference (part of References)

Install
-------
Installing the Node Reference URL Widget is simple:

1) Copy the nodereference_url folder to the sites/all/modules folder in your
installation.

2) Enable the module using Administer -> Modules (admin/modules)

3) Add or edit a Node Reference field from admin/structure/types/manage/[type]/fields.
When configuring the field, use the "Reference from URL" option.

4) Follow on-screen help text to configure your Node Reference URL Widget.

Advanced: Build your own links
------------------------------
Normally you can prepopulate a Node Reference URL widget simply by creating a
link with the following structure:

As HTML:
Add a story

Or in PHP code:
Add a story

However if using multiple Node Reference fields, you can populate them by
using a query string instead of embedding the IDs directly in the URL. Assuming
you had two fields, named "field_ref_a" and "field_ref_b", the URL to
prepopulate both of them at the same time would look like this:

In HTML:
Add a story

Or in PHP code:
Add a story

Advanced: Support for non-standard URLs
---------------------------------------
By default Node Reference URL Widget will only work with node form paths that
match the standard Drupal install: "node/add/%type", where %type is a node type
like "blog" or "story". If you want to use Node Reference URL Widget on
non-standard URLs, you may do so by informing Node Reference URL Widget of these
special paths.

To do so, add additional paths to your settings.php with the following code:

$conf['nodereference_url_paths'] = array(
'node/add/%type/%nid',
'node/%/add/%type/%nid',
);

Only two tokens are supported:
%type: The node type that will be created.
%nid: The node ID that will be referenced.

The % wildcard may be used when including other dynamic IDs.

In the above example, Node Reference URL Widget will work at either
"node/add/story/2" or "node/1/add/story/2", where "2" is the node ID being
referenced. Important to note: The first URL will be used in the links that Node
Reference URL Widget provides. If needing advanced configuration of links, look
into the Custom Links module: http://drupal.org/project/custom_links.
