  • Creating fields programmatically and not through field configuration

    Creating fields in a Drupal website is essential to organize and store data. Typically, the process involves using the Drupal field configuration interface. However, creating fields programmatically can also be an efficient approach, especially when dealing with large amounts of data.

    In Drupal, programmatically creating fields can be done using a combination of hooks and functions. The process involves defining the field's properties, such as its name, type, and storage options. The following is an example code snippet that demonstrates how to create a text field programmatically:

    use Drupal\field\Entity\FieldStorageConfig;
    use Drupal\field\Entity\FieldConfig;
    // Define the field storage configuration.
    $storage = FieldStorageConfig::create([
      'field_name' => 'field_example',
      'entity_type' => 'node',
      'type' => 'text',
    // Define the field configuration.
    $field = FieldConfig::create([
      'field_storage' => $storage,
      'bundle' => 'article',
      'label' => 'Example Field',
      'settings' => [
        'max_length' => 255,
    // Save the field configuration.
    The above code defines a text field with the field name "field_example," which is stored in a node entity and has a maximum length of 255 characters. The field configuration is assigned to the "article" content type.

    One of the advantages of creating fields programmatically is that it allows for automation and consistency when building Drupal websites. Fields can be created in bulk using scripts or modules, and can be easily version controlled. This approach also allows for the reuse of code, making it easier to maintain and update fields across multiple websites.

    In conclusion, programmatically creating fields in Drupal is a useful technique for developers who want to streamline their website building process. By using hooks and functions, fields can be quickly defined and added to entities, which provides greater control and flexibility.
