[mapguide-users] How to show a map (PHP)

[David Hequet]

i'm not sure it's possible to use
$resourceService->SetResource($resourceId, $byteSource->GetReader(), null);
for a mapdefinition.

I now undestand what you wan't to do:
To modify or create a mapdefinition before the layout loading

Here is what you can find in the Audoesk devnotes: (it was in C#, i used it
in VB.NET and it works)
This emulate what Mapguide do when you access a Layout:

If you want to get the MgMap object programmatically without displaying a
map in the Viewer (either DWF or AJAX), you need to follow these steps.
 
1. Initialize web tier with an ini file.
2. Connect to the site.
3. Instantiate an MgMap object.
4. Call MgMap.Create to actually create it.
5. Save the MgMap object to your session with MgMap.Save.
 

//1. $sessionId = valid session id
//2. $ressourceService = valid ressourceService

//3.
$aMap = new MgMap();
//4.
$resId = new
MgResourceIdentifier("Library://Samples/Map/".$aMapName.".MapDefinition");
$aMap->Create($resourceService, $resId, $aMapName);
//5.
$mapStateId = new
MgResourceIdentifier("Session:{$sessionId}//{$aMapName}.Map");
$aMap->Save($resourceService,$mapStateId);

hope this can help you, in VB.NET i had no problem, but in php i had an
"acces denied" error
if it work send me a mail please!
