Step 2 - Define the Point 2D field type

The Type class

The Type contains logic of the field type: validating data, transforming from various formats, describing the validators, and more. In this example Point 2D field type extends the Ibexa\Contracts\Core\FieldType\Generic\Type class.

For more information about the Type class of a field type, see Type class.

Field type identifier

First, create src/FieldType/Point2D/Type.php. Add a getFieldTypeIdentifier() method to it. The new method returns the string that uniquely identifies your field type, in this case point2d:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
<?php
declare(strict_types=1);

namespace App\FieldType\Point2D;

use Ibexa\Contracts\Core\FieldType\Generic\Type as GenericType;

final class Type extends GenericType
{
    public function getFieldTypeIdentifier(): string
    {
        return 'point2d';
    }
}

Add a new service definition

Next, add the ibexa.field_type tag to config/services.yaml:

1
2
3
4
services:
    App\FieldType\Point2D\Type:
        tags:
            - { name: ibexa.field_type, alias: point2d }
