How to print entity referenced fields (node) title in node.tpl.php?

Question

I want to print an entity referenced fields (node) title in node--customtype.tpl.php.

<?php print render($content['field_my_entity_reference']); ?> prints the field with some CSS class as below:

<div class="field-items">
<div class="field-item even">
<a href="/node/11">Entity Title</a>
</div>
</div>

What I want to do is to print this field without any pre-defined CSS classes etc..

[field_my_entity_reference] => Array
        (
            [und] => Array
                (
                    [0] => Array
                        (
                            [target_id] => 11
                            [entity] => stdClass Object
                                (
                                    [vid] => 41
                                    [uid] => 1
                                    [title] => Entity Title
                                    [log] => 
                                    [status] => 1
                                    [comment] => 1
                                    [promote] => 0
                                    [sticky] => 0
                                    [nid] => 11
                                    [type] => project
                                    [language] => es
                                    [created] => 1466009429
                                    [changed] => 1466502663
                                    [tnid] => 0
                                    [translate] => 0
                                    [revision_timestamp] => 1466502663
                                    [revision_uid] => 1
                                    [body] => Array
                                        (
                                            [und] => Array
                                                (
                                                    [0] => Array
                                                        (
                                                            [value] => 

I tried <?php print $node->field_my_entity_reference['und'][0]['entity']['title']; ?> but it gives error:

Fatal error: Cannot use object of type stdClass as array in

How can I print the title value of entity referenced field in node.tpl.php?

Answer 1

Alternative using the API is to use field_get_items and field_view_value.

Consider this example:

$field = field_get_items('node', $node, 'field_machine_name');
$title = field_view_value('node', $node, 'field_machine_name', $field[0]);
print render($title);

$title will produce...

Array
(
    [#markup] => test lang
    [#access] => 1
)

which is a renderable array.

The advantage of this against print $node->field_my_entity_reference['und'][0]['entity']->title; is the API will take care of the translation.

If you want to still use print $node->field_my_entity_reference['und'][0]['entity']->title I advice to avoid using und instead I will useLANGUAGE_NONE or much better $node->language.

print $node->field_my_entity_reference[$node->language][0]['entity']->title;

OK, without knowing anything about stdClass Object these kind of questions are normal :)

So, after reading a question about stdClass Object in SO I did what I want as below:

<?php print $node->field_my_entity_reference['und'][0]['entity']->title; ?>

This prints the title as plain text.

Note: Is there another way or better way you're always welcome.
