I have been tinkering with this problem and trying to research for a few hours. I am still getting familiar with the entity API for Drupal 7, and have been trying to work with PHP but to no avail–I think I am missing something VERY obvious as a result of my tired brain over-thinking things.<\/p>\n
I have two Content Types, CT1 and CT2. CT1 has a field that can hold multiple Field Collection values. In this Field Collection (field_coll_ct2) one of the fields (field_ct2_ref) is an Entity Reference to a node of content type CT2.<\/p>\n
Now, when I am looking at a single node of type CT1, I want a block View that will show me all of the CT2 nodes referenced in that CT1 node’s field_coll_ct2 field collection field.<\/p>\n
My primary approach, which has worked on non-field collection fields of the same kind of relation, is to add a contextual filter to the view on Content:NID. From there, since it is a block and URL parameter passing is out of the question (there are so many of these kinds of relations between 7-8 different content types, at different tuples per node, it is absolutely not feasible to use the URL for parameter-passing) I have it set to ‘Provide default value’ of type ‘PHP’ and ‘allow multiple values’ and here is where it gets hairy.<\/p>\n
I need to get all of the field_ct2_ref entity references in the currently-viewed node’s field_coll_ct2 field collections. I’ve tried using:<\/p>\n
$wrapper = entity_metadata_wrapper($entity_type, $entity);\nreturn $wrapper->field_coll_ct2->field_ct2_ref->value();\n<\/code><\/pre>\nor<\/p>\n
$node=menu_get_object(); \nforeach ($node->field_coll_ct2['und'] as $record) \n{ \n$values[]= $record['value'];\n} \nforeach($values as $val){\n$tgts[]=$val['every'][index]['possible'];\n}\nreturn $tgts[omg];\n<\/code><\/pre>\nand probably close to a hundred variations of the above trying to get it to return something that vaguely resembled an entity reference to a CT2 type node.<\/p>\n
I can’t seem to dig deeply enough into the entity\/field references to get to the field_ct2_ref[‘und’][0][‘target_id’] that has worked for all non-field collection fields with this kind of relationship. Or I get AJAX errors telling me ‘Unknown data property field_coll_ct2’ or console errors saying that every index I try to throw at these array objects (to even just get ONE of the values) is wrong.<\/p>\n
Is there an easier way of doing this? Am I missing something simple and obvious–either in the way I’m implementing my View or the PHP itself?<\/p>\n
For what it’s worth, I’ve been able to narrow down the view results without any contextual filter by selecting a relation to ‘Referencing Entity: field_ct2_ref’ but it shows ALL CT2 nodes referenced by ANY CT1 type node rather than the specific CT1 type node I’m looking at.<\/p>\n
Thank you!<\/p>\n
