Field Minimum Cardinality extends Drupal's built-in field cardinality system to enforce a minimum number of values on multi-value fields.
Drupal core already lets editors control how many values a field may hold (maximum cardinality), but provides no way to require more than one. This module fills that gap: once enabled, field administrators can set a lower bound on any configurable multi-value field, and content editors will receive a validation error if they save the entity without meeting it.
When would you use this?
- Require at least 2 tags on an article.
- Ensure a gallery field always has at least 3 images.
- Mandate that a quiz has a minimum number of answer options.
- Enforce a minimum number of related product references.
Post-Installation
No configuration page is needed. After enabling the module:
1. Navigate to Administration > Structure > Content types (or any entity type) > Manage fields.
2. Edit any multi-value field.
3. In the field settings form you will see a new "Minimum number of values" fieldset below the existing "Allowed number of values" control.
4. Enter the desired minimum (0 = no minimum) and save.
