__construct()

View source

Arguments

• $config

afterSave()

Performs actions after a component is saved.

View source

Arguments

• $isNew (boolean) – Whether the component is brand new

attributeLabels()

Returns the attribute labels.

Attribute labels are mainly used for display purpose. For example, given an attribute firstName, we can declare a label First Name which is more user-friendly and can be displayed to end users.

By default an attribute label is generated using generateAttributeLabel(). This method allows you to explicitly specify attribute labels.

Note, in order to inherit labels defined in the parent class, a child class needs to merge the parent labels with child labels using functions such as array_merge().

View source

Returns

array – Attribute labels (name => label)

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(): ?string
{
    // 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().
