class Value

Provides a form element for storage of internal information.

Unlike \Drupal\Core\Render\Element\Hidden, this information is not sent to the browser in a hidden form field, but only stored in the form array for use in validation and submit processing.

Properties:

• #value: The value of the form element that cannot be edited by the user.

Usage Example:

$form['entity_id'] = [
    '#type' => 'value',
    '#value' => $entity_id,
];
