Notice: Array to string conversion in _link_sanitize().

+1 subscribing. We're running into the same issue on two sites currently in development, with hundreds of nodes already imported into each one.

Changing the issue title - the problem isn't so much the Notice, as the fact that I moved things around and didn't produce a proper hook_update_N implementation to move the data.

This shouldn't require changing the link data, just the field data. That being said, I've created an update hook in link.install and comitted it just now - sometime soon (tomorrow?) you should be able to pull down the 7.x-dev version and run that. Let me know how that works, please.

Thanks for trying... I tried swapping out the 7.x.dev version and running update.php. I'm still getting an error, but on line 449 now:

Notice: Array to string conversion in _link_sanitize() (line 449 of /var/www/sites/clients/umiacs/dev/docroot/sites/all/modules/link/link.module).

Well, we need to change the Status if that didn't work. Hmm.

modulist, can you get me what's in field_config and field_config_instance for the field in question? The status of the fields after you've run the update would be great, although if you can also let me know what were in these fields before an after the update that would be useful for seeing what's going on in your code.

Also, what are you doing when you get the error? Viewing the node? submitting the node?

Thanks.

(Anyone else having this same error, after pulling down the latest code and running the update, that would be useful as well to get your data.)

since this issue is almost half a year old I close it since somebody can reproduce the error in latest dev release ...

I'm not fully sure if this is a upgrade issue. We are getting this on new sites that only runs on 7.x-1.0. Tracking down the error link, it is the rel attribute and a piece of code that is not working.

So in link_field_prepare_view() prior to _link_sanitize() we have an $item:

    url (String, 4 characters ) www.
    title (String, 6 characters ) Google
    attributes (Array, 1 element)
        title (String, 0 characters ) 

afterwards we have:

    url (String, 4 characters ) www.
    title (String, 6 characters ) Google
    attributes (Array, 1 element)
        rel (Array, 4 elements)
            title (String, 0 characters )
            class (String, 0 characters )
            rel (String, 0 characters )
            configurable_title (String, 1 characters ) 1
    display_url (String, 16 characters ) http://htsa/www.
    html (Boolean) TRUE

Internally, we have this:

  // Remove the rel=nofollow for internal links.
  if ($type != LINK_EXTERNAL && strpos($item['attributes']['rel'], 'nofollow') !== FALSE) {
    $item['attributes']['rel'] = str_replace('nofollow', '', $item['attributes']);
  }

which should be

  // Remove the rel=nofollow for internal links.
  if ($type != LINK_EXTERNAL && strpos($item['attributes']['rel'], 'nofollow') !== FALSE) {
    $item['attributes']['rel'] = str_replace('nofollow', '', $item['attributes']['rel']);
  }

This is not an issue on most sites as field_attach_prepare_view() will only be called once. On sites that have multiple calls (this is normal), the 'rel' is an array second time through and the warning is triggered.

Updating the title to the only issue that appears to remain.

Alan D.,

this should be solved with this issue #1441702: Rel attribute should have an option to get automaticly turned on/off if link is internal/external
