Hello,
client-side:
------------
- in handleHttpPostRequest(), set a class property with the value of
exampleSelecting
- in buildRequest(), instanciate the plugin request class (to write in
the common/ part of the plugin - have a look for instance at the outline
plugin common/ part) and insert your exampleSelecting value in order to
send it to the server part
- handleResult() and initializeResult() are only useful if you want to
handle the server part response. Else you may leave them empty.
server-side:
-------------
- $request is the plugin request object you have sent from the
client-side with buildRequest()
- depending on the request class you wrote, retrieve you raster filename
in for instance $request->exampleSelecting
- in handlePreDrawing(), write for instance:
$layer->data = $request->exampleSelecting
"the_new_raster_file_path" in my previous example was just a comment on
what to put in $layer->data

Bonjour Alexandre,
I made a client Plugin for the choice of a raster file name. The Client
Interface is a simple input text tag html.
With the Gui Provider, i can retrieve in a variable named exampleSelecting
for the name of a raster file.
That 's fine. I can see with handleHttpPostRequest that i can access to this
variable.
But
In your class ServerRasterfileSelector :
$request : what's this ?
"The_new_raster_file_path" is hard coded ? how; layer->data can contain my
data of exampleSelecting variable written by a user ?
How this handlePreDrawing method is called ? and by whom ?
The ServerCaller interface has 3 methods : buildRequest, handleResult and
initialiseResult.
What is the purpose of this 3 methods ?
i have a lack of information about all theses classes.
Merci pour ces éclaircissements.

Subject: Re: [Cartoweb-users] retrieve layers for the mapfile
Hello,
write a new plugin with a client part that retrieves the user choice
about the raster file to use (client class must implements the
"GuiProvider" interface) and transmits it to the server part of the
plugin (client class must implements the "ServerCaller" interface).
The server part may look like :
class ServerRasterFileSelector extends ClientResponderAdapter {
public function handlePreDrawing($request) {
$layer = new LayerOverlay();
$layer->name = "the_name_of_the_layer_to_update";
$layer->data = "the_new_raster_file_path";
$mapOverlay =
$this->serverContext->getPluginManager()->mapOverlay;
$mapOverlay->updateMap($layer);
}
}

Hello,
i have also this problem. J'ai aussi un problème similaire.
i would like to draw different raster file depending on the name of a
file on the fly. Je voudrai qu'un utilisateur choisisse un fichier
raster selon par exemple son nom et que le paramètre DATA d'une couche
soit modifié en conséquence à la volée.
Is it possible ? Comment effectuer cela. ?
Merci d'avance pour des éclaircissements.
