Correct way to render fields from Entities?

Question

This very popular article explains correct way to render fields: http://www.computerminds.co.uk/articles/rendering-drupal-7-fields-right-way

According to the article, the correct way to render fields is like this:

$node = node_load($nid);
$field = field_get_items('node', $node, 'field_name');
$output = field_view_value('node', $node, 'field_name', $field[$delta]);

But this is for rendering fields that are stored in a node. How would you use the code for fields in an entity?

I am using Paragraphs module that lets you create custom bundles in the predefined "paragraph" entity.

You can use entity.tpl.php to override the output of Paragraph module fields.

I want to print my fields that are stored in the entity, but the above code won't work because it is for nodes.

Answer 1

The equivalent to the sample code you posted from the article, but for an entity type other than node would be:

$entities = entity_load('ENTITY_TYPE_NAME', array($YOUR_ENTITY_ID));
$entity = $entities[$YOUR_ENTITY_ID];
$field = field_get_items('ENTITY_TYPE_NAME', $entity, 'field_name');
$output = field_view_value('ENTITY_TYPE_NAME', $entity, 'field_name', $field[$delta]);

If you're doing this in a template, your entity's fields should have already been retrieved by the entity module's template_preprocess_entity() function and made available under the $content variable, so you shouldn't have to do all these steps in an overridden entity template.

Answer 2

There is a function for that:

field_attach_view() I had to use it to get a renderable array from Paragraph entities (paragraphs module). Then you can render this array with the render() function ex:

$paragraphEntity = entity_load("paragraphs_item",array($paragraph['value']));
        //Per Paragraph field on the page-node get a renderable array of fields!
        $renderableParagraphBundle = field_attach_view("paragraphs_item", $paragraphEntity[$paragraph['value']], "full", $langcode = $GLOBALS['language']->language, $options = array());
        print render($renderableParagraphBundle);
