Bug fix suggestion: Selection widget fail with DateTime

[poulet1212]

By Querying features on the map which contain DateTime Attribute, Fusion generate a callback error:

Reason: MapGuide/php/Query.php uses MapGuide\php\Utilities.php to retrieve via GetPropertyValueFromFeatReader, properties values. Look at (about) line 881 MapGuide\php\Utilities.php:

$value =  GetPropertyValueFromFeatReader($featureReader,
                $properties->$layerName->propertytypes[$j],
                                                 $propname);
$value = htmlentities($value,ENT_COMPAT,'UTF-8');

this will only work if $value is a string. But GetPropertyValueFromFeatReader() returns a DateTime Object, that's why Fusion causes this callback error.

Proposition is: Getting a string representation of this DateTime Object:

$value =  GetPropertyValueFromFeatReader($featureReader,
                $properties->$layerName->propertytypes[$j],
                                                   $propname);
if($value instanceof MgDateTime)
  $value = printDateTime($value);
$value = htmlentities($value,ENT_COMPAT,'UTF-8');

where: printDateTime($value) is:

function printDateTime($mgDateTime)
{
   $dayToday = $mgDateTime->GetDay();
   $month = $mgDateTime->GetMonth();
   $year = $mgDateTime->GetYear();
   return $dayToday.".".$month.".".$year;
}

it goes nice then, Rémy

I have made a submission to the MapGuide tree which partially fixes this defect. The MgDateTime.ToString() method returns an Fdo compliant text representation of the date/time. This format should be suitable for roundtripping but is not a nicely formatted user string.

implemented this using the printDateTime function for backward compatibility - this may be changed to us MgDateTime->ToString() in the future
