Hi guys,

I have met a problem when i want to customize the form of creating/editing nodes.

Now i have a form for creating nodes of one content type. And there is a cck node reference field(checkbox) in this content type.

And in the form this field displays a list of checkboxes with reference node labels. If i want to use another field of refered content type to replace the labels, how can i do that?

I use form_alter, but it seems not working as expected. because this element's type in the form is nodereference_button and i cann't find out in which attribute it stores the data

and also the data format.

Any suggestions appreciated. Thanks...

Use the dsm() function provide by the Development (devel) module (http://drupal.org/project/devel) to analyze your form structure from within hook_form_alter. Every field that is included in the form will be listed in the array and dsm() will provide a printout in a collaspible tree that is easy to navigate. 


//print out form array using devel module
dsm($form);

When the printout first appears on your screen look at the first level for anything containing "node" or "reference" - I'm not sure what the container element is named for that type.

It seem that this dsm($form) is the same function with var_dump($form), maybe dsm() has a better outputs.

Thanks anyway!
