Hello everybody

I'm trying to use the method in subject with no result. CakePHP
1.1.18.

The PHP code in thtml is:

...
echo $html->input("Project/name",array("maxlength"=>"50","class"=>""));
...
echo $ajax->observeField(
               "ProjectName",
               array(
                  "update"=>"web",
                  "url"=>"/projects/webAlias/"
               )
          )?>
...

the rendered code (html) is the following

...
<input name="data[Project][name]"  maxlength="50" class="" value=""
type="text" id="ProjectName" />
...
<script type="text/javascript">
   new Form.Element.Observer('ProjectName', 2,
       function(element, value) {
          new Ajax.Updater('web','/projects/webAlias/', {
              asynchronous:true, evalScripts:true,
              parameters:Form.Element.serialize('ProjectName'),
              requestHeaders:['X-Update', 'web']}
          )
       }
   )
</script>

everything "works" except that it's returned to me that is missing
argument 1 for the controller action.

Maybe I'm missing some parameter to the observeField function.

Bye
Davide

Solved at moment making the function argument as optional and testing
for the existence of $this->data["Project"]["name"]

thank and bye

A strange thing regarding this topic.

I can't understand where's the problem.

Everytime I call the method with the observeField, all my Session data
is lost and so I'm disconnected.

It's the first time I'm using Ajax+AjaxHelper+Cake, so I could do
something wrong.

When I remove the observeField call, everything is fine.

Here is the code of the methods:

<?php
// app/controllers/projects_controller.php
class ProjectsController extends AppController {
...
   function beforeFilter(){
      parent::beforeFilter();
      array_push($this->helpers,"ajax");
   }
...
   function webAlias(){
      if(isset($this->data["Project"]["name"])){
         $this->layout = "ajax";
         $this->autoRender = false;
         echo $this->_webAlias($this->data["Project"]["name"]);
      }
   }

?>

<?php
/*
 * /app/app_controller.php
 */
class AppController extends Controller {
...
   function beforeFilter(){
      parent::beforeFilter();

      $aro = ALL;
      if($this->Session->check(ID)){
         $aro = $this->Session->read(ARO);
      }

      if(isset($this->params["controller"]) &&
isset($this->params["action"])){
         if($this->checkAccess($this->params["controller"],$this->params["action"],$ aro)){
         }else{
            $this->redirect("/pages/denied");
            exit;
         }
      }
   }

   /**
    * return a web alias starting from a provied string
    *
    * @param $string the provided string to be parsed
    * @return the translated string
    */
   function _webAlias($string){
      $ret = trim(strtolower($string));
      $ret = preg_replace("/[ ]/","-",$ret);
      $ret = preg_replace("/^[-]+/","",$ret);
      $ret = preg_replace("/[-]+\$/","",$ret);
      $ret = preg_replace("/[^a-z0-9-]/","",$ret);
      return $ret;
   }
...

?>

You might have to change some stuff in your config/core.php file.

Look for Session.checkAgent

Often you have do

Configure::write('Session.checkAgent', false);

to preserve sessions when using Ajax

Hope that helps.

Session.checkAgent is not defined in my core.php. I tried defining it

define("Session.checkAgent",false);

and call the Configure::write

  function webAlias(){
      if(isset($this->data["Project"]["name"])){
         Configure::write('Session.checkAgent', false);
         $this->layout = "ajax";
         $this->autoRender = false;
         echo $this->_webAlias($this->data["Project"]["name"]);
      }
   }

But none of them worked.

Some other ideas? Cake version 1.1.18.

D'oh -- that stuff I posted is Cake 1.2 specific.

I don't use Cake 1.1 at all, so can't help you there.

Ok Chris but you gave me a hint. So searching in the core code
(session.php) I saw three points where Session.checkAgent is
present. The only way I found (puttin some debug messages) for setting
this parameter was putting the Configure::write inside the
bootstrap.php, cause inside the core.php it seems to be ignored, or
maybe the core.php is read after the session.php; I've not got deeper
the question.

I've also tried to put it to false editing the core libs/configure.php
the only Session.checkAgent (line 340) but it seems to be ignored or
to be not enough for the problem.

Finally, I've solved, after restoring the old situation, making the
CAKE_SECURITY=medium in the app core.php (it was "high" before). Now
everything is working out right.

Thanks a lot
Bye
Davide
