[Cartoweb-users] Re: Problem with toolbar buttons

[Oliver Christen]

Hi

if the zoom or pan function dont work, then you have some major issue with your project, as this should always work. This is usualy a effect of a total failing of the javascript framework.
I would strongly suggest starting anew with the template of a working project.

as for query, if you added the correct metadata in the corresponding layer in the mapfile, it should return by default all the data associated with the selected features, as explained in the documentation.
you can interact with the query result in several way: specifying query_returned_attributes in the layer metadata, modifying the "table" coreplugin template, or adding a new "tablerules" plugin (see chapter 9 of http://cartoweb.org/doc/foss4g06/CartoWeb_GettingStarted.pdf) and more generaly http://www.cartoweb.org/cwiki/Foss4g06Workshops

Oliver

  Hello 
           Thanks a lot for all the details now many things are clear to me .
            I am able to load the new data aswell but the zoomin,zoomout and other
            functionalities are not working(when I am applying any operation on the 
            map like zoomin, zoomout etc. its not reflecting),though i have tried and 
            still in the process, please tell me which files are associated with the 
            working of these buttons.(zoomin,zoomout,panning,full extent etc.)

           In the same way I wanted to know in which files coding for the map 
           querying is done ,whenver we fire query then changes in which file 
           'll effect the results ?

           Looking forward to your reply.

  Regards
  Natasha

    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
