Assign anonymous node to user Id

Question

What I want to try and achieve.

An authenticated user creates a node of type 'listing' (this node obviously belongs to this user via his uid). On this node will be a link to create a new node of a different content type 'booking-request' (this link the author can't control).

Now an anonymous user can view this created 'listing' node and then they can click on the link and create a 'booking-request' node. So obviously the 'booking-request' node will belong to the anonymous user.

My question is. How can I assign this 'booking-request' node to the author of the 'listing' node after the anonymous user saves it?

Can I do this with a module or will this need custom php or both and how will I do this?

Answer 1

You can use Entity Reference Prepopulate.

Allow prepopulating any Entity reference field via URL

In your booking-request set up an entity reference field pointing to user entities. Then, create a link in the listing node to booking-request node add form with the right parameter to prepopulate that entity reference field.

See README in the module:

In order to pre-populate an entity reference field you have to supply the parameter in the URL.

The structure is node/add/article?[field_ref]=[id]

Where [field_ref] is the name of the entity reference field and [id] is the id of the entity being referenced.

Examples: node/add/article?field_foo=1 node/add/page?field_bar=1,2,3

You can do this in following way :

1. You can do this using Rules, by checking the condition if author is anonymous of newly added content then add action, select Set data value. Your target should be node:author. Assign the value you want.

2. Using hook_node_insert, add condition inside your hook :

   if ($node->type == 'your_type' && !$node->uid) { $node->uid = 1; }
