Returns the DB data type(s) that this field will store within the elements_sites.content column.

return \yii\db\Schema::TYPE_STRING;

Specifying the DB type isn’t strictly necessary, but it enables individual field values to be targeted by functional indexes.

If field values will consist of an associative array, each of the array keys can be specified here, so the nested values can receive their own functional indexes.

return [
    'date' => \yii\db\Schema::TYPE_DATETIME,
    'tz' => \yii\db\Schema::TYPE_STRING,

If null is returned, the field’s values won’t be stored in the elements_sites.content column at all. In that case, the field will be solely responsible for storing and retrieving its own values from normalizeValue() and afterElementSave()/afterElementPropagate().

string, string[], null – The column type(s).



Returns the field type’s SVG icon.

The returned icon can be a system icon’s name (e.g. 'whiskey-glass-ice'), the path to an SVG file, or raw SVG markup.

System icons can be found in src/icons/solid/.
