[opencms-dev] injecting Publish Date/Timestamp into page

[Paul-Inge Flakstad]

Hi Chris,

Like Bernd says, you probably want to avoid using "published" or "last-modified". ("Published" will never renew, and "last-modified" will renew too often - even after fixing typos).

For added control over the timestamp, *without* using an extra field/property, consider using the "date released" attribute. (Should be safe as long as you're not using it for any other customization.) We have chosen this approach, and it seems to work OK so far. Additionally, an unexpected benefit is that it allows us to do bulk updates on the timestamp (by updating it on a parent folder).

Here's a code suggestion:


CmsJspActionElement cms = new CmsJspActionElement(pageContext, request, response);
CmsObject cmso = cms.getCmsObject();
String resourceUri = cms.getRequestContext().getUri();

Date dr = null;
String drStr = null;
try {
    long drLong = cmso.readResource(resourceUri).getDateReleased();
    dr = drLong > 0 ? new Date(drLong) : null;
    drStr = new SimpleDateFormat("d MMM yyyy", locale).format(dr);
} catch (Exception e) {
    // No "date released" attribute set
}

if (drStr != null) {
    // Print the timestamp
}


HTH. 

Cheers,
Paul

Hi Chris,
you can find a lot of help in the pdf ship with OpenCms since version 8.
Find attached a screenshot with some useful resource related functions.

Hi Bernd,

nice idea. Do you happen to know which element to access to obtain the GetDateLastModified().
It looks like it's in CmsCntPageData.
