# fieldInformation {#tca-property-fieldinformation}

The `fieldInformation` is a reserved area within a single form element between
the label and the form element itself.

-   **fieldInformation**

    -   *Type:* array
    -   *Path:* $GLOBALS\['TCA'\]\[$table\]\['columns'\]\[$field\]\['config'\]
    -   *Scope:* Display

Extensions can register their own field information nodes, as shown in the
following example.

## Example {#tca-property-fieldinformation-example}

You can have a look at the extension `georgringer/news` in version 9.4 for an example:
[https://github.com/georgringer/news/blob/9.4.0/Configuration/TCA/tx_news_domain_model_news.php#L521](https://github.com/georgringer/news/blob/9.4.0/Configuration/TCA/tx_news_domain_model_news.php#L521)
(with `georgringer/news ^10.0` this was moved to a non-public extension).

**EXT:news/Configuration/TCA/tx_news_domain_model_news.php (Excerpt)**

```php
'tags' => [
    'config' => [
        // ...
        'fieldInformation' => [
            'tagInformation' => [
                'renderType' => 'NewsStaticText',
                'options' => [
                    'labels' => [
                        [
                            'label' => '',
                            'bold' => true,
                            'italic' => true,
                        ],
                    ],
                ],
            ],
        ],
    ]
```

The implementation can be found in [https://github.com/georgringer/news/blob/9.4.0/Classes/Backend/FieldInformation/StaticText.php](https://github.com/georgringer/news/blob/9.4.0/Classes/Backend/FieldInformation/StaticText.php):

**EXT:news/Classes/Backend/FieldInformation/StaticText.php**

```php
<?php

declare(strict_types=1);

namespace GeorgRinger\News\Backend\FieldInformation;

use TYPO3\CMS\Backend\Form\AbstractNode;

class StaticText extends AbstractNode
{
    public function render(): array
    {
        // ...

        return [
            'requireJsModules' => [
                'TYPO3/CMS/News/TagSuggestWizard',
            ],
            'html' => '...>',
        ];
    }
}
```

The custom FieldInformation must be rendered in `ext_localconf.php`:

**EXT:news/ext_localconf.php**

```php
$GLOBALS['TYPO3_CONF_VARS']['SYS']['formEngine']['nodeRegistry'][1552726986] = [
    'nodeName' => 'NewsStaticText',
    'priority' => 70,
    'class' => \GeorgRinger\News\Backend\FieldInformation\StaticText::class
];
```
