How do I return the value of a node reference field via PHP code in a view contextual filter?
I am attempting to do so via the following steps:
- Adding the node reference field in the contextual filters area
- Selecting "PHP Code" under "Provide default value"
I get stuck here because none of the data items provided by the Views module (
$argument) give access to the data saved in the node reference field.
In Drupal 6, the Views module gives access to a
$data variable which contains CCK data saved in nodes, but it seems there is nothing like that in Drupal 7.
