I have a custom field type that I create with a custom module. It is a plain text field where the user type in a string. I want to retain two copies of this field:
- The exact string value as typed by the user.
- A safe value of the same string.
This is how I create the field:
class MyItem extends FieldItemBase { /** * {@inheritdoc} */ public static function schema(FieldStorageDefinitionInterface $field_definition) { return [ 'columns' => [ 'value' => [ 'type' => 'text', 'size' => 'tiny', 'not null' => FALSE, ], 'safevalue' => [ 'type' => 'text', 'size' => 'tiny', 'not null' => FALSE, ], ], ]; } … }
I assume I should generate a safevalue of the string in hook_node_presave() and somehow get into the entity there (but corrections to these assumptions are welcome).
I have no problem getting the string value as typed by the user and to compute a safe value:
$value = $entity->field_myfield->getString(); $safevalue = makeSafe($value); But I do not know how to get the $safevalue stored in the database.
