i m using Liferay 6.2 and using Media Gallery Portlet to display the images which is placed in Multiple folders. i have multiple folders which contain multiple images but the folders are arranged according to alphabetical order but my requirement is to arrange the folders which are recently updated (i,e the recently updated folder must come at the top) so can anybody please provide solution how to achieve this.

thanks in Advance.

Answer 1

Over-ride view.jsp of /html/portlet/image_gallery_display by either hook or ext and add following two lines below the initialization of SearchContainer object at about line# 115:

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

This will order your Media Gallery's folders and images descending by modified date.

Update: If you want to control this behavior from preferences, then:

1. Declare and initialize these properties in init.jsp:

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

2. Add following drill-downs for value selection in configuration.jsp:

<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. Add these two lines in view.jsp below the initialization of SearchContainer:

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