是否可能仅为特定文件类型或TYPO3中特定子文件夹中的文件显示自定义sys_file_metadata ?

Question

我正在研究文件列表扩展名，想知道是否可以仅为特定文件类型(如pdf或特定子文件夹内的所有文件)设置额外的元数据。

到目前为止，我已经用以下设置扩展了sys_file_metadata:

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',
            'renderType' => 'selectMultipleSideBySide',
            'foreign_table' => 'tx_fileportal_domain_model_tag',
            'MM' => 'tx_fileportal_fileallocation_tag_mm',

                'edit' => [
                    'module' => [
                        'name' => 'wizard_edit',
                    ],
                    'type' => 'popup',
                    'title' => 'Edit',
                    'icon' => 'edit2.gif',
                    'popup_onlyOpenIfSelected' => 1,
                    'JSopenParams' => 'height=350,width=580,status=0,menubar=0,scrollbars=1',
                ],
                'add' => [
                    'module' => [
                        'name' => 'wizard_add',
                    ],
                    'type' => 'script',
                    'title' => 'Create new',
                    'icon' => 'add.gif',
                    'params' => [
                        'table' => 'tx_fileportal_domain_model_tag',
                        'pid' => '###CURRENT_PID###',
                        'setValue' => 'prepend'
                    ],
                ],
            ],
        ],
    ],
    'type' => [
        'exclude' => 1,
        'label' => $l1 . 'tx_fileportal_domain_model_file.type',
        'config' => [
            'type' => 'select',
            'renderType' => 'selectSingle',
            'foreign_table' => 'tx_fileportal_domain_model_filetype',
            'minitems' => 0,
            'maxitems' => 1,
            'items' => [
                ['Bitte wählen', 0]
            ],
            'appearance' => [
                'collapseAll' => 0,
                'levelLinksPosition' => 'top',
                'showSynchronizationLink' => 1,
                'showPossibleLocalizationRecords' => 1,
                'showAllLocalizationLink' => 1
            ]
        ]
    ]
];
TYPO3CMSCoreUtilityExtensionManagementUtility::addTCAcolumns('sys_file_metadata', $additionalColumns);
TYPO3CMSCoreUtilityExtensionManagementUtility::addToAllTCAtypes('sys_file_metadata', 'tags, type');
return $GLOBALS['TCA']['sys_file_metadata'];

这工作得很好，我可以为我的文件添加一些自定义标签和自定义更具体的类型，但这个选项现在可用于我的所有文件。是否有一种方法可以仅为特定的文件类型或特定子文件夹中的文件显示此选项，可能有显示条件?

Answer 1

您可以使用TCA中的displayCond来做到这一点。查看文档

如果您想要依赖某个字段，那么应该将该字段添加到表TCA的ctrl部分的requestUpdate选项中。检查文档

现在，如果该字段的值被更改，则会要求您重新加载表单，因为字段可能会更改

Answer 2

我不知道如何添加一个"requestUpdate"到sys_file_metadata的TCA，因为ExtensionManagementUtility不包含这样的东西还是我错了?到目前为止，显示条件对我来说是有效的，为了完整起见，下面是我使用条件的示例:
