我使用Liferay 6.2并使用Media Gallery Portlet显示放置在多个文件夹中的图像。 我有多个文件夹，其中包含多个图像，但文件夹按字母顺序排列，但我的要求是安排最近更新的文件夹（即，最近更新的文件夹必须位于顶部）所以任何人都可以提供解决方案如何为达到这个。

提前致谢。

Answer 1

通过hook或ext /html/portlet/image_gallery_display的view.jsp ，并在关于第115行的SearchContainer对象初始化下面添加以下两行：

OrderByComparator orderByComparator =
    DLUtil.getRepositoryModelOrderByComparator("modifiedDate", "desc");
searchContainer.setOrderByComparator(orderByComparator);

这将按照修改日期对Media Gallery的文件夹和图像进行排序。

更新：如果要从首选项控制此行为，则：

1. 在init.jsp声明并初始化这些属性：

String sortByCol = portletPreferences.getValue("sortByCol", "title");
String sortByOrder = portletPreferences.getValue("sortByOrder", "desc");

2. 在configuration.jsp为值选择添加以下下钻：

<div class="aui-column left-selector-column">
    <aui:select label="Sort By" name="preferences--sortByCol--">
        <aui:option label="Title" value="title"
            selected="<%= sortByCol.equals("title") %>" />
        <aui:option label="Create Date" value="creationDate"
            selected="<%= sortByCol.equals("creationDate") %>"/>
        <aui:option label="Modified Date" value="modifiedDate"
            selected="<%= sortByCol.equals("modifiedDate") %>" />
    </aui:select>
</div>

<div class="aui-column right-selector-column">
    <aui:select label="Order" name="preferences--sortByOrder--">
        <aui:option label="Ascending" value="asc"
            selected="<%= sortByOrder.equals("asc") %>"/>
        <aui:option label="Descending" value="desc"
            selected="<%= sortByOrder.equals("desc") %>"/>
    </aui:select>
</div>

3. 在SearchContainer初始化下面的view.jsp中添加这两行：

OrderByComparator orderByComparator =
    DLUtil.getRepositoryModelOrderByComparator(sortByCol, sortByOrder);
searchContainer.setOrderByComparator(orderByComparator);
