是否可以仅针对特定文件类型或TYPO3中特定子文件夹中的文件显示自定义sys_file_metadata？

Question

I am working on a file list extension and want to know if I can set additional meta data only for specific file types like pdf or for all files within a specific subfolder.

So far I have extended the sys_file_metadata with the following setup:

ext_tables.sql

CREATE TABLE sys_file_metadata (
    tags int(11) unsigned DEFAULT '0' NOT NULL,
    type int(11) unsigned DEFAULT '0'
);

CREATE TABLE sys_file_metadata_tags_mm (
    uid_local int(11) unsigned DEFAULT '0' NOT NULL,
    uid_foreign int(11) unsigned DEFAULT '0' NOT NULL,
    sorting int(11) unsigned DEFAULT '0' NOT NULL,
    sorting_foreign int(11) unsigned DEFAULT '0' NOT NULL,

    KEY uid_local (uid_local),
    KEY uid_foreign (uid_foreign)
);

sys_file_metadata.php

<?php
defined('TYPO3_MODE') || die();

$l1 = 'LLL:EXT:file_portal/Resources/Private/Language/locallang_db.xlf:';

$additionalColumns = [
    'tags' => [
        'exclude' => 1,
        'label' => $l1 . 'tx_fileportal_domain_model_file.tags',
        'config' => [
            'type' => 'select',

                'add' => [
                    'module' => [
                        'name' => 'wizard_add',

    ],
    'type' => [

            ],

                'showPossibleLocalizationRecords' => 1,
                'showAllLocalizationLink' => 1
            ]
        ]
    ]
];

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addTCAcolumns('sys_file_metadata', $additionalColumns);
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addToAllTCAtypes('sys_file_metadata', 'tags, type');

return $GLOBALS['TCA']['sys_file_metadata'];

This is working great and I can add some custom tags and a custom more specific type for my files, but this options are available for all my files now. Is there a way to display this options only for specific file types or for files within a specific subfolder, maybe with display conditions?

Answer 1

You can do that with displayCond in the TCA. Check the documentation .

If you want to depend on some field, that field should be added to the requestUpdate option in the ctrl section in the TCA of the table. Check the documentation

Now if the value of that field is changed, you're asked to reload the form as the fields may change.

Answer 2

I don't know how to add a "requestUpdate" to the TCA of sys_file_metadata, because the ExtensionManagementUtility don't contain something like this or am I wrong? Display conditions works so far for me and here is my example with conditions for the sake of completeness:
