I have a computed field in a Drupal 7 content type that is populated by my description (text) field:
$entity_field[0]['value'] = $entity->field_desciption['und'][0]['value'];
It works fine. I want to create another computed field that is populated by the title (Node module element) field.
I tried with the following lines, but they don't work.
$entity_field[0]['value'] = $entity->title['und'][0]['value'];
$entity_field[0]['value'] = $node->title;
How can I achieve this?
Use Exclude Node Title module.
https://drupal.org/project/exclude_node_title
Setting for this module:
Click on Module->Exclude node title->configure
Home » Administration » Configuration » Content authoring
Select All nodes from Basic Page
Check Full Content for hide title from all cms page except home page
Check Teaser for hide title from home page.
This will create an entity reference field for node content types with the article bundle.
$form['node_id'] = array(
'#type' => 'entity_autocomplete',
'#title' => $this->t('Node'),
'#target_type' => 'node',
'#selection_settings' => ['target_bundles' => ['article']],
'#tags' => TRUE,
'#size' => 30,
'#maxlength' => 1024,
);
Note you can change target_type for other entities like taxonomy_term.

The node title is not a field; therefore, using
$entity->title['und'][0]['value']will not work. What you should use is$entity->title.As side note, to get the value of a field, you should use field_get_items(), which takes care of the language set for the field, which isn't necessarily
LANGUAGE_NONE.
