Validation

Each Box config can define custom validation rules. These rules will be applied to the form in the Boxes editor.

To define custom validation rules, simply add a validation key to a Box config.

You can now define rules, attributeNames and customMessages to be used in October's Validation trait.

validation:
    rules:
        title:
            - required
            - numeric
            - "min:15"
    attributeNames:
        title: Title
    customMessages:
        title.min: "The title has to be at least 15 characters long"

Referencing other fields in validation rules

Boxes saves all Box data under a jsonable data column in the database.

This requires you to reference any other field name in your validation rules with the data. prefix:

Note, that the default relations (image, file, images, files) are not prefixed.

validation:
    rules:
        title:
            # Note the `data` prefix
            - required_if:data.type,1

form:
    fields:
        type:
            label: Type
            type: dropdown
            options:
                1: Title required
                2: Title optional
        title:
            label: Title
            type: text
