I face alot of problem when adding Entity Reference field

Ok, after some digging I found that our prepare and empty field callback calls was passing the field name instead of the field info array.

I hope it helps. Please note that I had other patches applied that may also affect the success of this patch.

The provided patch works fine for my entity reference,
but i still experience problems when i have a taxonomy reference with multiple terms.
It works when i choose the terms for every item, but when i use the bulk area and choose more then one term,
i get an ajax error as follows:

An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. Path: /de/batch?id=56&op=do StatusText: Service unavailable (with message) ResponseText: PDOException: SQLSTATE[21S01]: Insert value list does not match column list: 1136 Column count doesn't match value count at row 1: INSERT INTO {field_data_field_kategorie} (entity_type, entity_id, revision_id, bundle, delta, language, field_kategorie_tid) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5, :db_insert_placeholder_6_17, :db_insert_placeholder_6_20); Array ( [:db_insert_placeholder_0] => node [:db_insert_placeholder_1] => 26 [:db_insert_placeholder_2] => 26 [:db_insert_placeholder_3] => produkt_image [:db_insert_placeholder_4] => 0 [:db_insert_placeholder_5] => und [:db_insert_placeholder_6_17] => 17 [:db_insert_placeholder_6_20] => 20 ) in field_sql_storage_field_storage_write() (line 451 of C:\Users\tprinz\Workspace\duesenberg\htdocs\modules\field\modules\field_sql_storage\field_sql_storage.module).

if (!$empty_function($field_items, $field_info)) never validates true for my single value entity reference field.

Can someone explain the syntax of that line of code? I've never seen parameters passed to a variable.

I forced the validation to true with

if (strlen($field_items) > 0) { // instead of !$empty_function($field_items, $field_info)

However, when I attempted to save the nodes, I got a PDO error:

An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. Path: /batch?id=129&op=do StatusText: Service unavailable (with message) ResponseText: PDOException: SQLSTATE[HY000]: General error: 1366 Incorrect integer value: 'A' for column 'field_entitytest_target_id' at row 1: INSERT INTO {field_data_field_entitytest} (entity_type, entity_id, revision_id, bundle, delta, language, field_entitiytest_target_id) VALUES (:dn_insert_placeholder_0, :dn_insert_placeholder_1, :dn_insert_placeholder_2, :dn_insert_placeholder_3, :dn_insert_placeholder_4, :dn_insert_placeholder_5, :dn_insert_placeholder_6); Array ( [:dn_insert_placeholder_0] => node [:dn_insert_placeholder_1] => 404 [:dn_insert_placeholder_2] => 967 [:dn_insert_placeholder_3] => customcontenttest [:dn_insert_placeholder_4] => 0 [:dn_insert_placeholder_5] => und [:dn_insert_placeholder_6] => A ) in field_sql_storage_field_storage_write() (line 451 of /modules/field/modules/field_sql_storage.module).

Based on the value I attempted to enter and the error, I think what it's doing is returning the first letter of the entity name, instead of the entity target id.

Created patch fixing entity reference fields workflow

Updated patch, fixed empty function argument, missed that

@id.tarzanych: How is the patch in #7 related to https://www.drupal.org/node/2365497 ? Does this patch supersede that one?

@id.tarzanych: Since the patch in #7 bulk_photo_nodes_taxonomy_validate() is now acting on entity reference fields, and NOT taxonomy reference fields (because you changed $element['#value_key'] == 'tid' to $element['#value_key'] == 'target_id' . Was this change intentional?

We need to figure out what kind of validation should happen on taxonomy reference fields, and if nothing else, bulk_photo_nodes_taxonomy_validate() should be renamed...

#7 was just pushed to dev release. Thanks id.tarzanych!

Though we still need to determine what needs to by done regarding taxonomy reference fields, and whether bulk_photo_nodes_taxonomy_validate() should be renamed.
