[Cartoweb-users] Re: few queries

[Oliver Christen]

Hi

1) thats a bit too vague, can you be more precise?

2) http://www.cartoweb.org/doc/cw3.4/xhtml/image/intro/images/schema_flux.png
and http://www.cartoweb.org/doc/cw3.4/xhtml/intro.archi.html
Cartoweb has two parts, Cartoclient and Cartoserver. The Cartoserver interact with mapserver via mapscript (http://mapserver.gis.umn.edu/docs/reference/phpmapscript-class)
The generated data (map image, ...) are then then transfered to the Cartoclient which build the web page layout and the page is sent to the user browser. Once the page is displayed in the user browser, all actions are handled with javascript (zoom, pan, selection, ...) and the html form is sent back to the Cartoclient which process the action and transfert it to the Cartoserver (if needed) and the cycle start back.

3) Templates are based on SMARTY syntax. See smarty documentation (http://smarty.php.net/docs.php) and there is plenty of tutorials (http://smarty.php.net/crashcourse.php)
As for Cartoweb specificities, there is no documentation listing all the variable used in the templates. 
But usually all plugin and coreplugin have their own small templates files containing the related variables.
As for the main cartoclient.tpl file, experiement with the demo templates to get familiar with the various elements.

regards
Oliver

  Subject: few queries


  Hello
           1) how does the query option works in Cartoweb? (please mention the 
               files)

           2) which technology(as java applet is used in many cases what in case 
               of cartoweb?) is used behind the running of the main map 
               displayed at the front end in case of cartoweb. I basically want to  
               know the process of working of mapserver in case of cartoweb 
              specially.Is there any block diagram of process flow available?

           3) Can you please send me the documentation of templates( in order to 
              know the basic syntax of the template files used in cartoweb so that 
              modifications can be done in a proper manner as still there are few 
              syntax I am not familiar with .If its for beginners then good for me)

             Looking forward to your mail.

   Regards
   Natasha
