__construct()

Constructor.

The default implementation does two things:

• Initializes the object with the given configuration $config.
• Call init().

If this method is overridden in a child class, it is recommended that

• the last parameter of the constructor is a configuration array, like $config here.
• call the parent implementation at the end of the constructor.

View source

Arguments

• $config (array) – Name-value pairs that will be used to initialize the object properties

_volumeBySourceKey()

Returns a volume via its source key.

View source

Arguments

• $sourceKey

afterElementSave()

Performs actions after the element has been saved.

View source

Arguments

• $element (craft\base\ElementInterface) – The element that was just saved
• $isNew (boolean) – Whether the element is brand new

defaultSelectionLabel()

Returns the default selectionLabel value.

View source

Returns

string – The default selection label

displayName()

Returns the display name of this class.

View source

Returns

string – The display name of this class.

getContentGqlType()

Since

3.3.0

Returns the GraphQL type to be used for this field type.

View source

Returns

\GraphQL\Type\Definition\Type, array

getEagerLoadingGqlConditions()

Since

3.3.0

Returns an array that lists the scopes this custom field allows when eager-loading or false if eager-loading should not be allowed in the GraphQL context.

View source

Returns

array, false

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],
    // you can only pass the validator class name/handle if not setting any params
    '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 the available file kind options for the settings

View source

Returns

array

getSettingsHtml()

Returns the component’s settings HTML.

An extremely simple implementation would be to directly return some HTML:

return '<textarea name="foo">'.$this->foo.'</textarea>';

For more complex settings, you might prefer to create a template, and render it via craft\web\View::renderTemplate(). For example, the following code would render a template located at src/templates/_settings.html, passing the settings to it:

return Craft::$app->view->renderTemplate('plugin-handle/_widget-settings', [
    'widget' => $this
]);

If you need to tie any JavaScript code to your settings, it’s important to know that any name and id attributes within the returned HTML will probably get namespaced, however your JavaScript code will be left untouched. For example, if getSettingsHtml() returns the following HTML:

<textarea id="foo" name="foo"></textarea>
<script type="text/javascript">
  var textarea = document.getElementById('foo');
</script>

…then it might actually look like this before getting output to the browser:

<textarea id="namespace-foo" name="namespace[foo]"></textarea>
<script type="text/javascript">
  var textarea = document.getElementById('foo');
</script>

As you can see, that JavaScript code will not be able to find the textarea, because the textarea’s id attribute was changed from foo to namespace-foo. Before you start adding namespace- to the beginning of your element ID selectors, keep in mind that the actual namespace is going to change depending on the context. Often they are randomly generated. So it’s not quite that simple.

Thankfully, Craft provides a couple handy methods that can help you deal with this:

• craft\web\View::namespaceInputId() will give you the namespaced version of a given ID.
• craft\web\View::namespaceInputName() will give you the namespaced version of a given input name.

So here’s what a getSettingsHtml() method that includes field-targeting JavaScript code might look like:

public function getSettingsHtml()
{
    // Figure out what the ID is going to be namespaced into
    $id = 'foo';
    $namespacedId = Craft::$app->view->namespaceInputId($id);
    // Render and return the input template
    return Craft::$app->view->renderTemplate('plugin-handle/_widget-settings', [
        'id' => $id,
        'namespacedId' => $namespacedId,
        'widget' => $this,
    ]);
}

And the _widget-settings.twig template might look like this:

<textarea id="{{ id }}" name="foo">{{ widget.foo }}</textarea>
<script type="text/javascript">
  var textarea = document.getElementById('{{ namespacedId }}');
</script>

The same principles also apply if you’re including your JavaScript code with craft\web\View::registerJs().

Returns

string, null

getSourceOptions()

Normalizes the available sources into select input options.

View source

Returns

array

includeInGqlSchema()

Since

3.6.0

Returns whether the field should be included in the given GraphQL schema.

View source

Arguments

• $schema

Returns

boolean

init()

Initializes the object.

This method is invoked at the end of the constructor after the object is initialized with the given configuration.

View source

isValueEmpty()

Returns whether the given value should be considered “empty” to a validator.

View source

Arguments

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

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 hasContentColumn(), the value will be null.)

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

{
     return 'int|mixed|\\craft\\elements\\db\\ElementQuery';
}

View source

Returns

string
