Invalid argument type for functions in nodereferrer.module

I also experience this bug. It's worth mentioning that I get this message for lines 135-136 as well as 162-163. My version is 6.x-1.0-rc2 (with a PostgreSQL database backend).

# warning: array_filter() [function.array-filter]: The first argument should be an array in /var/www/drupal/sites/all/modules/nodereferrer/nodereferrer.module on line 135.

I have the same issue.

I am seeing same issue with 6.x-1.0-rc2. It appears only on nodes without a referrer it seems

Same here, 6.x-1.0-rc2:

warning: array_filter() [function.array-filter]: The first argument should be an array in
/sites/all/modules/nodereferrer/nodereferrer.module on line 135.
warning: array_values() [function.array-values]: The argument should be an array in

Please explain a steps to reproduce this bug

Is this still an issue? Please test against current 6-dev

Its still an issue with rc2. Havent tried it with dev.

But I think it is because I am using node reference url widget. Error disappears if I select the autocomplete widget (or any other default ones).

Anyone else using this module?

I'm having the issue, but not using reference URL widget.

Same issue, lines 135, 136 with nodereferrer-6.x-1.0-rc2

- on nodes without refering nodes

This seems to come with latest php versions that are more strict about data type.

I solved the issue by modifying lines 135-136 as follow
Current code

   case 'load':
      $types = isset($field['referrer_types']) ? array_values(array_filter($field['referrer_types'])) : array();
      $fields = isset($field['referrer_fields']) ? array_values(array_filter($field['referrer_fields'])) : array();

Modified code

   case 'load':
+    if (($field['referrer_types'])){
      $types = isset($field['referrer_types']) ? array_values(array_filter($field['referrer_types'])) : array();
+   }
+   if (($field['referrer_fields'])){
      $fields = isset($field['referrer_fields']) ? array_values(array_filter($field['referrer_fields'])) : array();
+   }

Idem for lines 162-163
Current code

      $types = array_values(array_filter($field['referrer_types']));
      $fields = array_values(array_filter($field['referrer_fields']));

Modified code

      if (($field['referrer_fields'])){
      $types = array_values(array_filter($field['referrer_types']));
      }
      if (($field['referrer_fields'])){  
      $fields = array_values(array_filter($field['referrer_fields']));
      }

can you provide a patch? also suppose we just need to change isset() to !empty() in both cases

I don't know how to create a patch. (I installed Tortoie svn/cvs on my windows pc, but it looks like a piece of crap, or I did not spent enough time to gets the logic.)
I haven(t tried to change isset only, but the code breaks before, while evaluating the arguments, so I don't think your proposal would make it.

Is it possible to fix this?
Thanks

bump?

Hi! Here's a patch that might work for comment #14

any reviews?
