Numeric item min/max settings ignored if set to 0

Created on 20 December 2016, over 7 years ago

Updated 24 November 2023, 7 months ago

Problem/Motivation

PHP's empty() function is not enough to check for $settings['min'] or $settings['max'] for numeric item - \Drupal\Core\Field\Plugin\Field\FieldType\NumericItemBase::getConstraints(), because their value can be numeric zero, and in such case constraint is not returned.

This results in possible invalid numeric values for items that have min or max boundary set to 0.

Rough example:

Custom entity class, baseFieldDefinitions()

    $fields['hour'] = BaseFieldDefinition::create('integer')
      ->setLabel(new TranslatableMarkup('Hour'))
      ->setSetting('min', 0)
      ->setSetting('max', 23);

Custom code

  $e = CustomEntity::create([ 'hour' => -100 ]);
  $violations = $e->validate();

Validation passes w/o errors, because NumericItemBase::getConstraints() does not return constraint to check for minimum.

Proposed resolution

Replace !empty() check with check for non-empty string (because an empty string is default value of min/max settings):

if ($settings['min'] !== '') {}

The issue summary at #3090629: NumericItemBase never sets minimum value constraint if minimum value is zero. → does look like it is solving the same problem and so does the code changes. I doubled checked and tested as well. I am closing this as a duplicate and moving credit over there.
