Error when using Autocomplete to add Existing Entity

I have the same issue here.

I used 7.x-1.0-rc1 initially, but the autocomplete field for adding existing node gave me somehting like "array(content type)". I have updated this module to 7.x-1.x-dev, still got this error as well.

Hope this can be fixed soon.

Attached patch fixes the issue for me. Please review and consider commiting.

Thanks very much. Patch works for us.

#2 Works for me. I tested it with Entity Reference fields (Node) that allow only 1 bundle type and another that allows multiple bundle types.

I don't think I'm allowed to mark this RTBC (just 2 reviews), but this is quite a big fail when using IEF.

#2 seems to work ok and really opens up this module to huge number of cases, including simplenews content selection. See How to create a newsletter containing existing content, using entity reference, rules and VBO for an example of this.

Thanks eiriksm! This works, I would RTBC it but it needs to pass tests first, so here it is as a git compatible patch.

Oh well, looks like tests aren't running for IEF...if someone can confirm the patch applies we can RTBC this.

Thanks for testing.

My patch is very much git compatible (did you not test it?). It is only different from yours in the way that i have used git format-patch to make it. That way the maintainer can use git am to apply the patch, to save himself 33 seconds of writing the commit message and stuff like that. :)

Since you basically have an identical patch (except the header) i would say you can feel free to mark as RTBC if it works for you.

Thanks for the clarification! RTBC, patch in #2 works perfectly!

Tweaked the variable names and committed:

Patch in #2 worked great. Thanks!

After #10 I have warning: "Warning: Invalid argument supplied for foreach() in inline_entity_form_autocomplete() (line 67"

Field options:
"Allow users to add existing nodes.": TRUE
"Target type": node
"Target bundles": my_type (one)

$entity_labels looks like:

array(
  nid => title
)

    foreach ($entity_labels as $bundle => $labels) {
      // Here it is already $entity_id as $bundle, $label as $labels
      // Loop through each entity type, and autocomplete with its titles.
      foreach ($labels as $entity_id => $label) {
        // entityreference has already check_plain-ed the title.
        $results[] = t('!label (!entity_id)', array('!label' => $label, '!entity_id' => $entity_id));
      }
    }

i can't reproduce #13 : i get no warning message.
so i think this is closed (fixed).

@ser_house : please try the latest version of the module.

I still have this issue, both in 7x-1.5 and the dev release of 2015-Feb-26. The error I get is this:

Warning: Invalid argument supplied for foreach() in inline_entity_form_autocomplete() (line 68 of …/sites/all/modules/contrib/inline_entity_form/inline_entity_form.module). Backtrace:

inline_entity_form_autocomplete('node', 'field_questions', 'survey', 'beva')
call_user_func_array('inline_entity_form_autocomplete', Array) menu.inc:517
menu_execute_active_handler() index.php:21

I hope I can find some time this or next week to dive into this (because I really like this module).
