Field type validation

Validator schema

The schema for validator configuration should have a similar format to the settings schema, except it has an additional level, to group settings for a certain validation mechanism:

• The key on the 1^st level is a string, identifying a validator
• Assigned to that is an associative array (2^nd level) of settings
• This associative array has a string key for each setting of the validator
• It's assigned to a 3^rd level associative array, the setting description
• This associative array should have the same format as for normal settings

For example, for the ibexa_string type, the validator schema could be:

[
    'stringLength' => [
        'minStringLength' => [
            'type'    => 'int',
            'default' => 0,
        ],
        'maxStringLength' => [
            'type'    => 'int'
            'default' => null,
        ]
    ],
];
