Frontend

The auto suggest plugin works on the frontend using HTML data attributes.

{namespace as=SyntaxOOps\Autosuggest\ViewHelpers}

<f:form.textfield
    name="my_field"
    additionalAttributes="{as:suggestDataAttributes(identifier: 'news', pids: '123',
    additionalParameters: {table: 'tx_news_domain_model_news', field: 'title', recursive: 1, recursive_depth: 99})}"
/>

The extension provides the auto suggest ViewHelper namespace. This namespace is automatically loaded.

Alternatively, you can use TypoScript for the configuration and pass only the identifier to the ViewHelper.

{namespace as=SyntaxOOps\Autosuggest\ViewHelpers}

<f:form.textfield
    name="my_field"
    additionalAttributes="{as:suggestDataAttributes(identifier: 'news')}"
/>

plugin.tx_autosuggest {
    settings {
        news {
            storagePids {
                0 = 123
                1 = 213
                2 = 312
            }
            additionalParameters {
                table = tx_news_domain_model_news
                field = title
                recursive = 1
                recursive_depth = 99
            }
        }
    }
}

Backend

Enable auto suggest for backend input fields

$GLOBALS['TCA']['tx_news_domain_model_news']['columns']['author']['config']['autosuggest'] = [
    'identifier' => 'news',
    'table' => 'tx_news_domain_model_news',
    'field' => 'title',
    'storage_pids' => '123,213,312',
    'additionalUriParameters' => [
        'recursive' => true, // include subfolder of storage_pids
        'recursive_depth' => 999
    ], // applied to data-json-path uri path
    'additionalParameters' => [
        'data-combobox-case-sensitive' => 'no',
        'data-combobox-search-option' => 'containing',
        'data-combobox-limit-number-suggestions' => 10,
    ],
];

Custom Suggest Services

A new concept, Suggest Services has been introduced. These are singleton classes designed to provide data for suggestion features.

To register a suggested service, add the registration code to your extension’s ext_localconf.php file:

$GLOBALS['TYPO3_CONF_VARS']['EXT']['autosuggest']['custom'] =
    \Vendor\MyExtension\Service\Suggest\CustomSuggestService::class;

The array key custom serves as the SuggestService identifier.
This is the value you will use in your ViewHelper to access its suggestions.

Once registered, create the corresponding service class to provide the data.
The class can either :

Extend GenericSuggestService.php class

/**
 * Class CustomSuggestService
 */
class CustomSuggestService extends GenericSuggestService
{
    protected string $type = 'custom';
}

Or implement SuggestServiceInterface.php interface.

/**
 * Class CustomSuggestService
 */
class CustomSuggestService implements SuggestServiceInterface
{
    /**
     * @return array
     */
    public function generateItems()
    {
        return [
            [
                'name' => 'Example Title 1'
            ],
            [
                'name' => 'Example Title 2'
            ],
            [
                'name' => 'Example Title 3'
            ]
        ];
    }
}

Clear caches and you're ready to go!

Note

The extension provides an abstract service class, AbstractExtbaseSuggestService.php.
This class can be extended to create Extbase-based suggest services, allowing you to fetch data using queries, repositories, or other Extbase mechanisms.
