\GraphQL\Type\Definition\Type, array

getEagerLoadingGqlConditions()

Since

3.3.0

getElementValidationRules()

Returns the validation rules for an element with this field.

Rules should be defined in the array syntax required by yii\base\Model::rules(), with one difference: you can skip the first argument (the attribute list).

[
    // explicitly specify the field attribute
    [$this->handle, 'string', 'min' => 3, 'max' => 12],
    // skip the field attribute
    ['string', 'min' => 3, 'max' => 12],

    'bool',
]

To register validation rules that should only be enforced for live elements, set the rule scenario to live:

[
    ['string', 'min' => 3, 'max' => 12, 'on' => \craft\base\Element::SCENARIO_LIVE],
]

View source

Returns

array

getFileKindOptions()

Returns

array

Returns

boolean – Whether the value should be considered “empty”

normalizeValue()

Normalizes the field’s value for use.

This method is called when the field’s value is first accessed from the element. For example, the first time element.myFieldHandle is called from a template, or right before getInputHtml() is called. Whatever this method returns is what element.myFieldHandle will likewise return, and what getInputHtml()’s and serializeValue()’s $value arguments will be set to.

The value passed into this method will vary depending on the context.

• If a new, unsaved element is being edited for the first time (such as an entry within a Quick Post widget on the Dashboard), the value will be null.
• If an element is currently being saved, the value will be the field’s POST data.
• If an existing element was retrieved from the database, the value will be whatever is stored in the field’s content table column. (Or if the field doesn’t have a content table column per \craft\fields\hasContentColumn(), the value will be null.)
• If the field is being cleared out (e.g. via the resave/entries command with --to :empty:), the value will be an empty string ('').

There are cases where a pre-normalized value could be passed in as well, so be sure to account for that.

View source

Arguments

• $value (mixed) – The raw field value
• $element (craft\base\ElementInterface, null) – The element the field is associated with, if there is one

Returns

mixed – The prepared field value

phpType()

Since

If the values can be of more than one type, return multiple types separated by |s.
