[maplab-users] Code to add MapSize to Maplab

[Bryan Tolka]

Add mapsize to Maplab(GMAP Factory)
Note: Some of code used is from the GMAP demo.

1.) Add this javascript to index.html under <SCRIPT> tags.

function mapsize()
 {
     if (document.forms[0].MapSize.selectedIndex != 0 &&
         document.forms[0].MapSize.selectedIndex !=1)
     document.forms[0].submit();
 }

2.)Change your main.php file.

Change
$oMapSession->oMap->set( "width", MAP_WIDTH );
$oMapSession->oMap->set( "height", MAP_HEIGHT );

to:

 if ($HTTP_GET_VARS["MapSize"])
    {
 if (ereg("([0-9]+),([0-9]+)", $HTTP_GET_VARS["MapSize"], $MapSizeExtents))
         {
             $WidthPixel = intval($MapSizeExtents[1]);
             $HeightPixel = intval($MapSizeExtents[2]);
 
             $oMapSession->oMap->set("width",$WidthPixel);
             $oMapSession->oMap->set("height",$HeightPixel);

 $oMapSession->oMap->set( "width", MAP_WIDTH );
 $oMapSession->oMap->set( "height", MAP_HEIGHT );

             $oMapNavigator->zoomOut( 999999 );
         }
     }
    
 else
 {
 $oMapSession->oMap->set( "width", $MAP_WIDTH );
 $oMapSession->oMap->set( "height", $MAP_HEIGHT );
 //     debugging       print("$MAP_WIDTH   $MAP_HEIGHT");
 }


3.) Change you globalprefs.php file

Change this:

define( "MAP_WIDTH", "400" );
define( "MAP_HEIGHT", "300" );

to
$MAP_WIDTH=400;
$MAP_HEIGHT=300;

4.) Add this code somehwhere in your contents.php file.
I will let the guys at DM add this to the gmapfactory of placement.


<td bgcolor="#333333"><FONT FACE="Arial, Helvetica, sans-serif" SIZE="2">
        <SELECT NAME="MapSize" onChange="mapsize()">


        <OPTION>Map Size</OPTION>

          <OPTION>---------------</OPTION>

          <OPTION VALUE="400,300"
                <?php if (($omap->width == 400) && ($omap->height == 300))
                 echo "SELECTED";?>> 400 x 300</OPTION>

          <OPTION VALUE="600,450"
                 <?php if (($omap->width == 600) && ($omap->height == 450))
                 echo "SELECTED";?>> 600 x 450</OPTION>

          <OPTION VALUE="800,600"
                 <?php if (($omap->width == 800) && ($omap->height == 600))
                 echo "SELECTED";?>> 800 x 600</OPTION>
          <OPTION VALUE="1024,768"
                 <?php if (($omap->width == 1024) && ($omap->height == 768))
                 echo "SELECTED";?>> 1024 x 768</OPTION>
        </SELECT>
