Alternative Ext Direct PHP Implementation

[Dumbledore]

is there a reason for following code?

ExtDirect/API.php Line 95

$cSettings['fullPath'] = $this->getClassPath($name, $Settings);

when i change this line to

$cSettings['fullPath'] = $this->getClassPath($name, $cSettings);

i was able to set individiual paths for each Class via basePath...

Tommy,
did you have something special in mind in using

getNumberOfRequiredParameters()

instead of

getNumberOfParameters()

to get the functions parameters in order to construct the length?

I stumbled upon this on a function where I was initializing some parameters in the function declaration, and they were not counting in the parameter len config for the remote procedure.

Hello community,
just wanted to share this experience I had, in case somebody else stumbles upon this behavior. Hopefully it will save you some time

I don't know how many of you have tested this solution with the reflection capabilities of php, but I found something strange happening.

I was playing around with the example classes, and changed the file class a bit.
After that when I called the api.php, I was only getting back the actions of the file class and not any of the other files.

I debugged the php side and found out that once a class has been analyzed with the reflection tools, the next time it get's analyzed, the

                    if(    $rMethod->isPublic() &&
                        strlen($rMethod->getDocComment()) > 0
                    ) 

code fails. This meant that for some reason the 'getDocComment()' command returned real data only the first time it parses a class method.

Since I am new to reflections and just starting to experiment I was not sure if this is a bug in PHP or some config issue with Tommy's implementation.

I did some goggleing and found this bug which kind of reminded me of this behaviour:
http://eaccelerator.net/ticket/229

and indeed it was an eaccelerator (that I am using) bug which was fixed and the solution is also explained in the link I provided. You should also install the latest version of course....

Hi Could anyone explain how to catch up the exception result formed in Router.php:

          } 
            catch(Exception $e)
            { 
                $response = array(
                    'type' => 'exception',                    
                    'tid' => $cdata->tid,
                    'message' => $e->getMessage(),
                    'where' => $e->getTraceAsString()
                );
            } 

In Ext script I'm on success and failure events and just can't catch this response

            FormPanel constructor
            ...
            buttons:[{
                text: 'Enter',
                id: 'submit',
                handler: doSubmit
            }],
            // configs for BasicForm
            api: {
                // The server-side must mark the submit handler as a 'formHandler'
                submit: Ext.ss.Auth_Demo.login
            },
            // specify the order for the passed params    
            paramsAsHash: true
        });

        function doSubmit()
        {        
            basicInfo.getForm().submit(
            { 
                waitMsg: '????????',
                waitTitle: '???? ????????..',
                params: 
                {
                    username : 'username',
                    password : 'password'
                },
                success: function(form, action)
                {
                    Ext.Msg.alert(':)');

                    basicInfo.ownerCt.close();
                },
                failure:function(form, action)
                { 
                    if(action.failureType == 'server')
                    { 
                        Ext.Msg.alert(':(');
                    } 
                }
            }); 
        }

Hi

Thanks for posting this updated version.

I found a bug in API.php --

Line 54 reads:

 if(isset($state['nameAttribute'])) {
            $this->setFormAttribute($state['nameAttribute']);
        }

It should read:

  if(isset($state['nameAttribute'])) {
            $this->setNameAttribute($state['nameAttribute']);
        }

This was causing errors when working with forms and direct.

Best Regards

Hi Could anyone explain how to catch up the exception result formed in Router.php:

I too would like to know how to catch an exception from this, firebug says "result is undefined" when the result is

{"type":"exception","tid":"2","message":"New and repeat passwords do not match","where":"#0 [internal function]: ExtLib_Password->passwd(Array, Array)\n#1 \/var\/www\/localhost\/htdocs\/lib\/ExtDirect\/Router.php(176): call_user_func_array(Array, Array)\n#2 \/var\/www\/localhost\/htdocs\/lib\/ExtDirect\/Router.php(62): ExtDirect_Router->rpc(Object(BogusAction))\n#3 \/var\/www\/localhost\/htdocs\/lib\/router.php(17): ExtDirect_Router->dispatch()\n#4 {main}"}

[mrsunshine]

you can for example catch the ext direct exception event

Ext.Direct.on(
  'exception'
  function(e){
    // do something with the exception information
    console.log(e);
  }
);
