Typo3 Extbase過濾器（按系統類別）

Question

您好，我為我的extbase擴展啟用了類別

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::makeCategorizable

工作正常，但是如何過濾要在前端顯示的元素，以便后端用戶可以為插件元素選擇類別？

添加一個FlexForm。 為此，請將其添加到您的ext_tables.php中

\TYPO3\CMS\Extbase\Utility\ExtensionUtility::registerPlugin(
    'Vendor.' . $_EXTKEY,
    'Pluginname',
    'My plugin description as shown to the backend user'
);
$pluginSignature = strtolower(\TYPO3\CMS\Core\Utility\GeneralUtility::underscoredToUpperCamelCase($_EXTKEY)) . '_pluginname';
$TCA['tt_content']['types']['list']['subtypes_addlist'][$pluginSignature] = 'pi_flexform';
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPiFlexFormValue($pluginSignature, 'FILE:EXT:' . $_EXTKEY . '/Configuration/FlexForms/myflexform.xml');

配置flexform，以便您可以選擇一個類別：

<T3DataStructure>
    <sheets>
        <settings>
            <ROOT>
                <TCEforms>
                    <sheetTitle>Settings</sheetTitle>
                </TCEforms>
                <type>array</type>
                <el>
                    <settings.myCategory>
                        <TCEforms>
                            <label>Category</label>
                            <config>
                                <type>group</type>
                                <internal_type>db</internal_type>
                                <allowed>sys_category</allowed>
                                <foreign_table>sys_category</foreign_table>
                                <size>1</size>
                                <minitems>0</minitems>
                                <maxitems>1</maxitems>
                            </config>
                        </TCEforms>
                    </settings.myCategory>
                </el>
            </ROOT>
        </settings>
    </sheets>
</T3DataStructure>

請參閱此處以供參考： https : //docs.typo3.org/typo3cms/CoreApiReference/DataFormats/T3datastructure/Index.html

然后在控制器操作中使用該值，例如$this->settings['myCategory']並將其傳遞到存儲庫中的查詢中。
