Extremely Easy Ext.Direct integration with PHP

[Trii]

Thanks Trii... I came to the same conclusion myself shortly afterwards. I typed that discovery into a post here, but I guess I forgot to press "submit". But thanks anyway - I appreciate your help.

Whilst you and I are here.... I don't suppose you've got any thoughts about how to use this integration in a polling process? I don't have a scooby where to start.

(Scooby => Scooby Doo => clue)

Look into Ext.util.TaskRunner() You can use that to start a task that calls an arbitrary callback every interval. It's hard to give you a more detailed response without knowing more about what you are trying to poll and when you should start and when you should end. you can use your callback on the executeHooks to register a polling task with the task runner

Ah! Thanks Trii. I'd kind of glossed over that, misinterpreting what it was. But yes, that looks like it'll do the trick!

Thanks again for all your help,
Andy

Hi all,

I'm using this ExtDirect integration a lot and I found something that I want to change. If you setup a DirectStore with the "api" parameters (code below), "baseParams" are received server-side in one object, not multiples parameters.

DirectStore (incomplete code):

        this.store = new Ext.data.DirectStore(
        {        
            pruneModifiedRecord: true,
            autoLoad: true,
            api: 
            {
                read    : Ext.php.get.Store,
                create  : Ext.php.set.StoreCreate,
                update  : Ext.php.set.StoreUpdate,
                destroy : Ext.php.del.Store
            },
            baseParams:
            {
                databaseTable: 'jos_gtr_batiment_bat',
                displayField: 'nom_BAT',
                valueField: 'id_BAT',
                idField: 'id_BAT',
                returnAllFields: true
            }, 

Doing code above, I have to setup this PHP class:

class del 
{    

    function Store($datas)
    {        
        $database_table = $datas->databaseTable;
        $idField = $datas->idField; 

But I want to achieve this:

class del 
{    

    function Store($databaseTable,$displayField,$valueField,$idField, $returnAllFields)
    { 

Any advice on how to do that ?

Thanks,

Stephane

Since I didn't see anything in the .zip file itself, what license is this code released under?

Sorry. In my ignorance, I see the whole licensing issue as complicated, and I never spent the time reading and studying it enough to have a good comprehension of the characteristics and differences between the most known open source licenses...

All I can tell is that what I currently think about the code license is something like:

1. You are free to do anything you want with it.
2. You are responsible for the consequences of the code usage (meaning: the author is not responsible if you misuse, or use it in an unsafe manner, etc.)
3. I will be happy if you don't remove the "author" comment in the code.

Hmmm... maybe I should add these words as a "license.txt" in the zip?

A new version has been released today.

Just go to post #1 of this thread, and the new ZIP file is there.

Five new configuration options were added, four of them of callback type: "declare_method_function", "authorization_function", "transform_result_function", and "transform_response_function"

Now, you are able to specify an "authorization_function", where you can check the user permissions and return true or false accordingly, allowing the API call or not.

With the "transform_result_function", you can modify the result of the API method call after its execution, but before it is sent to the client-side.

Finally, with the "transform_response_function", you can modify the response structure. This allows to fire server-side events, and to send extra server side data together with the RPC result.

I am too busy to write detailed instructions about the new features.

Here is some sample code:

// New configuration option
ExtDirect::$id = 'my_api';

// All "function" configurations accept parameters of callback type
ExtDirect::$transform_result_function   = 'transform_result';
ExtDirect::$transform_response_function = 'transform_response';
ExtDirect::$declare_method_function     = 'declare_method';
ExtDirect::$authorization_function      = 'authorize';

    function transform_result( $action, $result )
    {
        if ( $action->form_handler )
            $result = array( 'success' => $result );
        
        return $result;
        // return modified result
    }
    
    function transform_response( $action, $response )
    {
        $response['error_msg']   = MyFramework::$errors;
        $response['success_msg'] = MyFramework::$success;
        return $response;
        // return modified response
    }
    
    function declare_method( $class, $method )
    {
        $key = $class . '::' . $method;
        return in_array( $key, MyFramework::$user->permissions );
        // return boolean - declare the method in the API or not
    }
    
    function authorize( $action )
    {
        return declare_method( $action->action, $action->method );
        // return boolean - authorize the action call or not
    }

// Types of the parameters received by the functions are:
// $action - ExtDirectAction
// $result - array
// $response - array
// $class - string
// $method - string 

Feedback is appreciated.

Thanks!

Excellent Job! This is a great Ext.Direct implementation. Has there been any updates to this since August?

[ttbgwt]

Do you have an example on how to configure and load a DirectStore using your implementation?

No updates since August. This is currently the latest version. (Today is October 26, 2010.)

I have developed a PHP / MySQL application (a basic CMS) making intensive use of this implementation. In the future, when this CMS is more mature, I want to open source it too.

Several components data are loaded using DirectStore (treepanel, treegrid, grid, list, etc.) - in the server side, the data source is MySQL (or Memcached).

I do not have a simple/small sample to post, but if you specify more details about what do you want, I may help.
