fieldInformation

fieldInformation

Path: $GLOBALS['TCA'][$table]['columns'][$field]['config']
type: array
Scope: Display
Types: check, flex, group, imageManipulation, input, none, radio

Show information between an element label and the main element input area. Configuration works identical to the "fieldWizard" property, no default configuration in the core exists (yet). In contrast to "fieldWizard", HTML returned by fieldInformation is limited, see FormEngine docs for more details.

Hint

fieldInformation is not implemented by default. Use Description to display general information below a fields title.

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 (with georgringer/news ^10.0 this was moved to a non-public extension).

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

'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:

<?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

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