如何在前端按日期降序对TYPO3扩展fal_securedownload进行排序？

我写

您试图按“crdate”排序，但要按其排序的子对象属性的路径是properties.creation\u date。
此代码应适用于：

{namespace sd=BeechIt\FalSecuredownload\ViewHelpers}
<ul>

<f:for each="{folder.subFolders}" as="subFolder">
            <sd:security.assetAccess folder="{subFolder}">
                  <li><span class="icon-folder {sd:leaveState(folder:subFolder, then:'icon-folder-open')}" data-folder="{subFolder.combinedIdentifier}">{subFolder.name}</span>
                        <f:render partial="FileTree/Leaf" arguments="{folder:subFolder}" />
                  </li>
            </sd:security.assetAccess>
      </f:for>
        <f:for each="{folder.files->v:iterator.sort(order: 'DESC', sortBy: 'properties.creation_date')}" as="file">
                  <sd:security.assetAccess folder="{folder}" file="{file}">
                  <li><span class="icon-file icon-file-{file.extension}"></span><sd:downloadLink file="{file}">{file.name}</sd:downloadLink> (<f:format.date format="%d.%m.%Y">{file.properties.creation_date}</f:format.date> - <f:format.bytes value="{file.properties.size}" />)</li>
            </sd:security.assetAccess>
      </f:for>
</ul>

{namespace sd=BeechIt\FalSecuredownload\ViewHelpers}

{子文件夹.名称}

{file.name}（{file.properties.creation_date}-）

在不知道扩展名的情况下，您正在使用“{file.properties.creation\u date}”作为输出，您是否尝试过sortby=“properties.creation\u date”？谢谢，这很有效，您让我开心！谢谢我现在用这个，这个很好：@j4k3你能添加正确的答案吗？那太好了。：）@托马斯勒·弗勒完成了。：）
