Drupal 7 get teaser with field_view_value()

Question

I have an Ajax handler script where I load a $nodeId and output the result in default (full) view:

$node = node_load($input);
$prerendered_node = node_view( $node, 'default' );
...

Now I need to display the teaser (summary or trimmed) as well.

I tried this so far, without success (summary is filled in content):

1.
$item = $node->body['en'][0];
$output = field_view_value('node', $node, 'body', $item, 'Teaser');
echo $output; (blank)

2. echo $node->body['eng']['0']['summary']; (blank)

A solution from this question but not working:

3. $output = truncate_utf8(strip_tags($node->body['eng']['0']['summary']),200,true,true);
echo $output; (blank)

Curious is that var_dump($node->body['eng']['0']) displays and array containing value (of body), summary, clean_summary and other elements and the summary has the necessary value filled. But as in example 2 I can't directly access it, it's coming up blank on display.

Tips, please?

Thank you.

Answer 1

The correct way to do this without accessing the value directly (so you automatically get an internationalised version I think) is shown below:

$node = node_load($nid);
$body = field_get_items('node', $node, 'body');
$teaser = field_view_value('node', $node, 'body', $body[0],'teaser');

To output the $teaser value, you need to pass it to the render() function

print render($teaser);
