FR: Event aliases with date/time

[Anke]

For SEO reasons it would be nice to have the event date in automaticaly generated aliases, e.g. /eventdetails/fitness-training-2016-02-16.html.

Currently, I think, Contao generates the alias from the event title followed by a unique number if the title isn't unique. Would it be possible to generate the alias from the event title and the start date, then followed by a unique number, if necessary?

I bet that would interfere with reccuring events.
But you can easily implement Rich-Snippets within your event-Template which is seo-wise much more effective.

You can set the alias manually or create your own save_callback for the alias field, which implements this automatic behaviour.

@Anke: I put the following into dcaconfig.php:

// Always prefix the event alias with the start date (yyyy-mm-dd-),
// unless it begins with a date already
$GLOBALS['TL_DCA']['tl_calendar_events']['fields']['alias']['save_callback'][] = 
    function($varValue, DataContainer $dc)
    {
        if (!empty($varValue) and $dc->activeRecord and !preg_match('/^\d{4}-\d{2}-\d{2}-/', $varValue)) {
            $varValue = date('Y-m-d-', $dc->activeRecord->startDate) . $varValue;
        }
        return $varValue;
    }
;

If you want put the date at the end you'd change the pattern to '/-\d{4}-\d{2}-\d{2}$/ and swap date/varValue in the next line. The code does not care (not know) if the alias is automatically generated or not.
