[Cartoweb-users] writing new plugin

[oliver]

Hi Giuseppe,

did you add "implements FilterProvider " in your plugin class definition ? Otherwise your plugin wont understand what are filterGetRequest and filterPostRequest

otherwise, try doing a x($request) in your filterPostRequest function to see whats inside and eventually see if something is wrong.

Regards,
Oliver

  Hi,
  I fixed the first error, due to a naming error. Now, the plug in is found but I get the following error:

  Class : CartocommonExceptionMessage : Error [8, Undefined property:  ClientRicerca::$request, C:\wamp\www\cartoweb3\projects\MyProject\plugins\Ricerca\client\ClientRicerca.php, 21]


  My target consists on building up a new recenter plugin. I've followed the indications into HowToWriteANewRecenterPlugIn. This new plugin gets a text string (name of a building and so on) and recenters the map on the specific point. In  a db, there is the relation between name and coordinates. 
  I've created a new folder and put the template into it, and that is ok, the plugin find the coordinates but than it crashes and returns the error above.
  That is my code :


  public function filterGetRequest(FilterRequestModifier $request) {}

      public function filterPostRequest(FilterRequestModifier $request) {
      $searchString = $request->getValue('buildName');
      if (!empty($searchString)) {

          // To simplify we assume that only one result is returned by the search
          list($x, $y) = $this->makeSearch($searchString);

          $this->request->setValue('recenter_x', $x);  (1)
          $this->request->setValue('recenter_y', $y);  (2)

      }

  protected function makeSearch($searchString) {
   // db connection atc.

   return array($x, $y);

  }

  If I delete the lines (1) and (2) there's no error but I don't get the recentering. Can you help me?
  Is  there a way to set a fixed zoom so I get a visible map in a time ?

  In my not-smarty plugin, I've set the distances for x and y to set a fixed box around the found center.

  Thanks in advantage

    Hi Giuseppe,
    first, be sure you didnt used any function that require a server side ( your plugin must not implements ServerCaller), 
    also you must not call your plugin on the server side (in server_conf/yourproject/yourproject.ini it must not be in loadPlugins = ...)
    otherwise it may be something to do with the functions or objects you have used but i cant say without seeing your actual code.

    Regards,
    Oliver

      Hi Alexandre,
      in my first attemp, I wrote a new feature by linking a new  html/php page in the main page, the results is ok but it's no too "smarty", then I've just tried to follow the suggested procedures,   HowToWriteaRecenterPlugin,  Ive called my new plugin  myPlugin (what a immagination ), but when I recall my project (which works fine in Cartoweb 3.2 ) I get : 

      Couldn't load plugin ServerMyPlugin.
       
      No errors during the compilation. I've not written any server plugin, but it seems I 'm not supposed to do .
      what's wrong ?

      Thanks in advantage.

        Hello,

        have a look at this tutorial:
        http://cartoweb.org/cwiki/HowToWriteaRecenterPlugin

        The plugin writing principles are obviously the same for other kinds of 
        plugins...
