php - 如何在 TYPO3 10 中以自定义 extbase 扩展的 flexform 创建文件上传字段？

Question

我尝试在 TYPO3 10 中以 extbase 扩展的 flexform 创建文件上传字段。由于 TYPO3 10 不支持 internal_type“文件”，我尝试了下面给出的代码。

<settings.bgImage>
    <TCEforms>
        <label>Background Image</label>
        <config>
            <type>inline</type>
            <maxitems>1</maxitems>
            <foreign_table>sys_file_reference</foreign_table>
            <!--<foreign_field>uid_foreign</foreign_field>-->
            <foreign_table_field>tablenames</foreign_table_field>
            <foreign_label>uid_local</foreign_label>
            <foreign_sortby>sorting_foreign</foreign_sortby>
            <foreign_selector>uid_local</foreign_selector>
            <foreign_selector_fieldTcaOverride type="array">
            <config>
                <appearance>
                    <elementBrowserType>file</elementBrowserType>
                    <elementBrowserAllowed>jpg,jpeg,png,svg</elementBrowserAllowed>
                </appearance>
            </config>
            </foreign_selector_fieldTcaOverride>
            <foreign_match_fields type="array">
                <fieldname>image</fieldname>
            </foreign_match_fields>
            <appearance type="array">
                <newRecordLinkAddTitle>1</newRecordLinkAddTitle>
                <createNewRelationLinkTitle>Add Image</createNewRelationLinkTitle>
                <headerThumbnail>
                    <field>uid_local</field>
                    <height>64</height>
                    <width>64</width>
                </headerThumbnail>
            </appearance>
        </config>
    </TCEforms>
  </settings.bgImage>

但这也无法正常工作。请帮我解决这个问题。谢谢

这是一个当前工作的完整 FlexForm，只有一个 FAL-Image 字段。配置再次更改... :-(

更新：我将在这里展示一个 ViewHelper 以及如何使用它......

模板示例

{namespace t=Your\Extension\ViewHelpers}

<f:for each="{t:FAL(uid=entry.uid, field='image', table='tt_content')}" as="preview">
    <div class="preview">
        <f:image src="{f:uri.image(image=preview)}" title="{preview.title}" />
        <figcaption>{preview.title} {preview.description}</figcaption>
    </div>
</f:for>

ViewHelper 示例

<?php
namespace Your\Extension\ViewHelpers;
use TYPO3Fluid\Fluid\Core\Rendering\RenderingContextInterface;
use TYPO3Fluid\Fluid\Core\ViewHelper\AbstractViewHelper;
use TYPO3Fluid\Fluid\Core\ViewHelper\Traits\CompileWithRenderStatic;
use TYPO3\CMS\Core\Resource\ResourceFactory;
use TYPO3\CMS\Core\Utility\GeneralUtility;

class FALViewHelper extends AbstractViewHelper
{
    use CompileWithRenderStatic;

    public function initializeArguments()
    {
        $this->registerArgument('table', 'string', '', false);
        $this->registerArgument('field', 'string', '', true);
        $this->registerArgument('uid', 'integer', '', true);
    }
    public static function renderStatic( array $arguments, \Closure $renderChildrenClosure, RenderingContextInterface $renderingContext)
    {
        $resFactory = \TYPO3\CMS\Core\Resource\ResourceFactory::getInstance();
        $table = $arguments['table'] != NULL ? $arguments['table'] : 'tt_content';
        $field = $arguments['field'];
        $uid = intval($arguments['uid']);

        $fileRepository = GeneralUtility::makeInstance(\TYPO3\CMS\Core\Resource\FileRepository::class);
        $fileObjects = $fileRepository->findByRelation($table, $field, $uid);

        return $fileObjects;
    }
}

解释

图像通过表 sys_file_reference 解析。

当您查看它时，您会发现这些字段将填充您的扩展数据：- tablenames，- fieldname 和 - uid_foreign

一个 flexform 字段可能有tt_contentas tablenames，imageasfieldname和你的扩展 tt_content 记录的 uid as uid_foreign。

flexform 定义了<fieldname>image</fieldname>... 这将成为fieldname.

模板必须告诉 ViewHelper 要查找的内容：{t:FAL(uid=entry.uid, field='image', table='tt_content')}

• entry.uid 必须与您的内容元素的 uid 匹配。
• field='image' 必须与 FlexForm 字段名匹配。
• 该表必须与存储数据的表匹配。（此处：tt_content）

如果您在扩展中使用它，则需要将表名更改为您的tx_yourextension_whatever. 您可能还会更改字段名...

笔记

这段代码似乎仍然会产生一些弃用警告......我还没有弄清楚，如何克服这些：-/
