[mapguide-users] Problem with $resourceService (PHP)

Wed Oct 29 11:01:28 EDT 2008

You can enable display of PHP errors by modifying the php.ini file in the WebServerExtensions/Php folder. Change the setting of "display_errors" to On. This should help to determine the source of any script errors. You'll probably need to re-start the web tier for this to take effect.

Regarding Problem 1:

This script is intended to be launched from a web layout, which will already have instantiated a session-based map resource. In your case, it is getting run before you load the web layout, so if you want it to succeed, you need to use $map->Create instead of $map->Open. (Note that the variable $mgMapName that you are using is not currently defined in your script).

Something like this should work (though it doesn't actually do anything with the SRS once it has it):

        // Get the user information using the session id,
        // and set up a connection to the site server.
        $userInfo = new MgUserInformation($sessionId);
        $siteConnection = new MgSiteConnection();
        $siteConnection->Open($userInfo);
          $mapResourceId = new MgResourceIdentifier("Library://Samples/Sheboygan/Maps/Sheboygan.MapDefinition");
          $mgMapName = "MySheboyganMap";

        // Get an instance of the required service(s).
        $resourceService = $siteConnection->CreateService(MgServiceType::ResourceService);

        // Display the spatial reference system used for the map.
        $map = new MgMap();
        $map->Create($resourceService, $mapResourceId, $mgMapName);
        $srs = $map->GetMapSRS();

Regarding Problem 2:

I think there was a bug at one time where the session ID didn't get passed in to the script being invoked. That could be what's causing your problem. What version of the product are you using?

Chris.

Subject: [mapguide-users] Problem with $resourceService (PHP)

Hello,

I have two problems so If anyone knows something I would appreciate his/her
help.

Problem 1
when I define a resourceService, my page doesn't show.

The code is copy - paste from Dev's Guide:

<?php
        $installDir = 'C:\Program Files\MapGuideOpenSource\\';
        $extensionsDir = $installDir . 'WebServerExtensions\www\\';
        $viewerDir = $extensionsDir . 'mapviewerphp\\';
        include $viewerDir . 'constants.php';

        MgInitializeWebTier($extensionsDir . 'webconfig.ini');

        $site = new MgSite();
        $site->Open(new MgUserInformation("Administrator", "admin"));
        $sessionId = $site->CreateSession();

        $webLayout
="Library://GoSpatial/WebLayout/Autostrada+Brescia+Padova+Map.WebLayout";

        // Get the user information using the session id,
        // and set up a connection to the site server.
        $userInfo = new MgUserInformation($sessionId);
        $siteConnection = new MgSiteConnection();
        $siteConnection->Open($userInfo);

        // Get an instance of the required service(s).
        $resourceService =
$siteConnection->CreateService(MgServiceType::ResourceService);

        // Display the spatial reference system used for the map.
        $map = new MgMap();
        $map->Open($resourceService, $mgMapName);
        $srs = $map->GetMapSRS();

?>
<html>
<head>
<title>Simple Sample Application</title>
</head>
<body marginheight="0" marginwidth="0">
<iframe id="viewerFrame" width="100%" height="100%" frameborder=0
scrolling="no"
src="http://127.0.0.1:8008/mapguide/mapviewerajax/?SESSION=<?=$sessionId?>&WEBLAYOUT=<?=
$webLayout ?>&username=Administrator&password=admin"></iframe>
</body>
</html>

If I comment the lines from where I define $resourceService till the end of
php script, my map is loading...

Problem 2
When I try to run the phpSamples (for example the Hello Map) and I press on
the "Display Spatial Reference  ", I get the following error:

"Error: Invalid argument(s): [1] = "" The session ID is invalid because the
session separator character was not found. Exception occurred in method
MgUserInformation.SetMgSessionId at line 165 in file
c:\build_bond_area\mapguide_open_source_v1.2\build_18.1\mgdev\common\mapguidecommon\System/UserInformation.cpp"

Generally, I cannot run any of the samples...

Thanks in Advance!
