[mapguide-dev] GetLocalizedString

[Walt Welton-Lair]

It's a static helper method used to look up a localized string by name
(name="DISTANCEMETERS" in this case).  The source for the method (not
particularly interesting) is in the file PhpLocalizer.cpp in this
folder:
 
https://mapguide.osgeo.org/source/browse/mapguide/trunk/MgDev/Web/src/Ph
pApi/
 
The localized strings are stored in resource files, and the locale
argument specifies which file to use.  In the open source vault the
resource files are located in this folder:
 
https://mapguide.osgeo.org/source/browse/mapguide/trunk/MgDev/Web/src/lo
calized/.
 
Don't know offhand where the web tier install actually puts them - look
for a "localized" folder.
 
The vault only contains the English resource file, named "en".  Using
that locale, the returned string in this example would be "Meters".  The
coordinate system doesn't come into play.

Looking at the Last line of the Selected Code         "$unitsType =
GetLocalizedString("DISTANCEMETERS", $locale);"

What is happening here??? Im not a PHP programmer and I cant find a
function Called GetLocalizedString anywhere....

...What would this be in a Map with no Coordsys? Or is that Irrelevant?

 

 

 

//get the map extent and calculate the scale factor

        //

        $mapExtent = $map->GetMapExtent();

        $srs = $map->GetMapSRS();

        if($srs != "")

        {

            $csFactory = new MgCoordinateSystemFactory();

            $cs = $csFactory->Create($srs);

            $metersPerUnit =
$cs->ConvertCoordinateSystemUnitsToMeters(1.0);

            $unitsType = $cs->GetUnits();

        }

        else

        {

            $metersPerUnit = 1.0;

            $unitsType = GetLocalizedString("DISTANCEMETERS", $locale);

        }
