Configuration

Below is the full configuration available with defaults values:

"example" => [
    "type"   => "anomaly.field_type.checkboxes",
    "config" => [
        "default_value" => null,
        "options"       => null,
        "min"           => null,
        "max"           => null,
        "mode"          => "checkboxes",
        "handler"       => "Anomaly\CheckboxesFieldType\CheckboxesFieldTypeOptions@handle"
    ]
]

Configuration

Key	Example	Description
default_value	foo	The default value key.
options	`["foo" => "Foo", "bar" => "Bar"]`	The option array. Values may optionally be non-keyed.
min	3	The minimum selections allowed.
max	10	The maximum selections allowed.
mode	tags	The input mode. Valid options are `checkboxes` and `tags`.
handler	`\Example\Test\MyOptions@handle`	The option handler. You may also specify `countries` or `states` to use alternate built-in handlers.

Option Groups

Checkbox options can be organized into groups by nesting the options into keyed groups. The key is translated as the group's label.

"options" => [
    "module::message.examples" => [
        "foo" => "FOO",
        "bar" => "BAR",
    ],
    "module::message.tests" => [
        "baz" => "BAZ",
    ],
]

Option Handlers

Option handlers are responsible for setting the available options on the field type. You can define your own option handler to add your own logic to available options.

You can define custom handlers as a callable string where @handle will be assumed if no method is provided:

"handler" => \App\Example\MyOptions::class // Assumes @handle

Option handlers can also a handler with a closure:

"example" => [
    "config" => [
        "handler" => function (CheckboxesFieldType $fieldType) {
            $fieldType->setOptions(
                [
                    "foo" => "FOO",
                    "bar" => "BAR"
                ]
            );
        }
    ]
]

Closures can not be stored in the database so your closure type handlers must be set / overridden from the form builder.{.note}

Writing Option Handlers

Writing custom option handlers is easy. To begin create a class with the method you defined in the config option.

"handler" => "App/Example/MyOptions@handle"

The handler string is called via Laravel's service container. The CheckboxesFieldType $fieldType is passed as an argument.

Handlers are called through Laravel's service container so method and class injection is supported.{.tip}

<?php namespace App/Example;

class MyOptions
{
    public function handle(CheckboxesFieldType $fieldType)
    {
        $fieldType->setOptions(
            [
                "foo" => "FOO",
                "bar" => "BAR"
            ]
        );
    }
}
