allow user to choose from his own referenced nodes

Question

I have two content types: business listing, product listing. "Product listing" has an Entity Reference field. This field points to the nodes of "business listing". I want to allow user to choose from his own "business listing" nodes (during adding a "product listing" node). I have created a view to list the nodes of "business listing" type and have Added a Entity Reference display to the view. Then have selected the view Under "Entity selection". Now, I have a problem in adding proper contextual filter. I have added a contextual filter of "Content: Author Uid" and selected "provide default value".

a) if I select "USER ID from logged in user" as default value:

This solution will break if an admin is editing the node. The field will then show only nodes the current user (admin) has created.

b) if I select {"User ID from URL" and "Also look for a node and use the node author"}: This solution will break if an user is adding a new node. The field will not show any nodes!

How can I achieve this?

Answer 1

For type: select PHP Code

and put this code in there.

$url = $_SERVER['HTTP_HOST'] . request_uri();
$getnid = explode("/", $url);
$var = $getnid[2];

if (is_numeric($var)) { 

  $node = node_load($var);
  return $node->uid;

} else { 

  global $user;
  return $user->uid;

}

Explanation of code

Line 1 gets the current page url

Line 2 implements the explode php function

Line 3 grabs the 2nd / from the url

Then we use an if statement to check if line 3 is a number or not:

• If it is a number then it has to be the node/2/edit form. The 2 is the nid, which we then use to grab the author (uid).
• Else, if it's not a number, then we know that it is the node/add form. So since it doesn't have a number in the url, we use the logged in user uid instead.

Answer 2

No need to write any code for this. Use reference_option_limit module properly in your content types & when you create view and provide default value 'User ID from URL' - Please mark the checkbox 'Also look for a node and use the node author' to true.

Enjoy !!!

Answer 3

You could add the author uid to the url for creation and editing.

node/add/contenttype/123 and node/#/edit/123 where 123 is the current user during creation and is the author during edit.

Make your entity reference view pick the raw value from url.
