fieldInformation

fieldInformation

Type: array
Path: $GLOBALS['TCA'][$table]['columns'][$field]['config']
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

Currently, fieldInformation is implement for all form elements, except in cases where it does not make sense. You can use description to display general information between a fields title and the form element itself.

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
];
