node reference default value with php

Its
" 'nid' as it is and replace 'value for nid' for the actual id of the node i'm tring to reference? "

Which means

return array(0 => array('nid' => 5)); 

should work...

Be sure to not actually include the < ?php ... ? > delimiters

I did this for the default value :

return array(0 => array('nid' => $_GET['storynumber']));

and then called the add like this :

node/add/story/?storynumber=5

Works for us, although I'm not sure this is the proper way to do it.

i am also trying to figure out how to get the default value to show up properly. what i have is a view that lists several nodes based on taxonomy. each row has a node being displayed and also has a node reference cck field. i would like to make the default value for the node reference to be itself for each node - i.e. the default node reference to nid 300 is 300. how can i do this? is there somewhere that i might find what format to place the default values in? thanks.

I'm not sure how you would do that, since when you create a new node the nid is still blank at this time. You probably need to use hook_nodeapi when the $op is equal to insert. For example :

function your_module_nodeapi(&$node, $op) {

if ( $node->type == 'your_node_type' && $op == 'insert') {
$node->field_your_field[0]['nid'] = $node->nid;
}

}

Here's one way that works. Include the following code in the default PHP value for your nodereference field:

$path_info = menu_get_item();
$default_nid = $path_info['page_arguments'][1]; // change this number to use a different part of the path
if (is_numeric($default_nid)) {
  return array(0 => array('nid' => $default_nid));
}
else {
  return array(0 => array('nid'));
}

One problem with this code: It doesn't check whether the node is of the right type, which can create problems. Anyone know an easy way to figure out which node types are referenceable for the field that's being filled?

Here's how this code works. menu_get_item() returns an array with lots of information about the page you're calling. Of particular interest is the element 'page_arguments', which is an array containing each part of the path. For instance, here's the output I get from menu_get_item() when I go to /node/add/degree/4:

Array
(
    [path] => node/add/degree
    [load_functions] => 
    [to_arg_functions] => 
    [access_callback] => node_access
    [access_arguments] => a:2:{i:0;s:6:"create";i:1;s:6:"degree";}
    [page_callback] => node_add
    [page_arguments] => Array
        (
            [0] => degree
            [1] => 4
        )

    [fit] => 7
    [number_parts] => 3
    [tab_parent] => 
    [tab_root] => node/add/degree
    [title] => Degree
    [title_callback] => check_plain
    [title_arguments] => 
    [type] => 6
    [block_callback] => 
    [description] => An educational degree earned by a Person in the database.
    [position] => 
    [weight] => 0
    [file] => modules/node/node.pages.inc
    [href] => node/add/degree
    [options] => Array
        (
        )

    [access] => 1
    [localized_options] => Array
        (
            [html] => 1
        )

    [map] => Array
        (
            [0] => node
            [1] => add
            [2] => degree
            [3] => 4
        )

)

Anyone have a simpler way?

$refnid = arg(3); //i get the argument from the url: "node/add/story/5"
return array( 0 => array('nid' => $refnid),);

Instead, try this:

if (is_numeric($refnid)) {
  return array( 0 => array('nid' => $refnid));
} else {
  return array( 0 => array('nid'));
}

That "else" handles null values (works if you're doing a db call and might have no result, too, or any other such case). I found that further down the comments here.

Although I prefer the various methods mentioned above there's actually a module which provides this functionality: prepopulate

I could really use some help with picking the nodeprofile reference variable to use to set the Default value. I'm using the code posted by eoneillPPH above:

$refnid = $field_p_node_ref[0]['nid']; //(my CCK node ref field)

if (is_numeric($refnid)) {
  return array( 0 => array('nid' => $refnid));
} else {
  return array( 0 => array('nid'));
}

If I hardcode $refnid to an actual profilenode id (ie, 101), it works just fine, however I just cant find the right variable/value to use to programmatically grab the user's profilenode id. I've tried just about every variable i can find, but it just isn't giving me the referenced node id.

Any suggestions?

Ok, after many hours of guesswork and then finally a little thought, I came up with a working solution for my problem:

$refnid = node_load(array('type'=>'profiles', 'uid'=>$node->uid));

return array(
    0 => array('nid' => $refnid->nid )
);

What it does is load the current logged in user's nodeprofile (based on their uid), which then gives me access to the nid of their profile.

It feels hacky, but it works.

I have a node type called property and at the bottom of the node is an add event link this has a node_referrer field that allows a user to choose the property node linked to that event. What I would really like to do is AUTOMATICALLY populate the events property_node_referrer field based on the property node we have just come from.

@clockwood: doesn't seem hacky to me...
@artatac: this is not related to this thread - you might want to look at http://drupal.org/project/prepopulate

I think this issue is fixed now ?

return array(0 => array('nid' => 5)); 

why it is not work ?
