In this article show the same example but using only ZendFramework.

I will take the same example used in the previous article, just changing the class to use PHP classes abstraction database ZendFramework. We begin with our gateway.php

PLAIN TEXT
PHP:
  1. <?php
  2. require_once 'Zend/Config.php';
  3. require_once 'Zend/Db.php';
  4. require_once 'Zend/Amf/Server.php';
  5. require_once 'Zend/Amf/Exception.php';
  6. require_once 'Zend/Amf/Server.php';
  7. $server = new Zend_Amf_Server();
  8. $server->setProduction(false);
  9. $server->setClass('Contato');
  10. echo($server->handle());
  11. ?>

Running the link into your browser, you should see the following message:

Zend Amf Endpoint

Then modify in our main class, which will perform the operations list, insert, delete and update data from our database:

In ActionScript only need to change what will be passed to PHP, instead of VOs, send Arrays:

PLAIN TEXT
ACTIONSCRIPT3:
  1. public function insertData():void
  2.             {
  3.                 var contatosVO:Array = [];
  4.                 contatosVO['nome']= input_nome.text;
  5.                 contatosVO['email'] = input_email.text;
  6.                 ro.insertData(contatosVO);
  7.             }

In the Adobe documentation, it is recommended to use AMFPHP or pure PHP, but this integration can be used seamlessly together with ZendFramework (using ZendAMF)
Ryan Stewart wrote two articles that show how this implementation with PHP and REST.

A note on the article by Ryan, in Flex 4, Adobe introduced the use of swfobject, then the mode of getting the URL and pass parameters to the SWF looks like this:

PLAIN TEXT
JAVASCRIPT:
  1. var xiSwfUrlStr = "playerProductInstall.swf";
  2. var flashvars = {};
  3. {
  4.     flashvars.roomURL = swfobject.getQueryParamValue("roomURL");
  5.     flashvars.authToken = swfobject.getQueryParamValue("authToken");
  6. }
  7. var params = {};

In LCCS sdk, there is a file called lccs.php, just copy it to the same directory of your class zend. Then add the include in your gateway.php

PLAIN TEXT
PHP:
  1. <?php
  2. require_once 'Zend/Amf/Server.php';
  3. require_once 'lccs.php';
  4. require_once 'Test.php';
  5.  
  6. /** Bootstrap */
  7.  
  8. // Instantiate server
  9. $server = new Zend_Amf_Server();
  10. $server->setProduction(false);
  11. $server->setClass('Test');
  12. // Handle request
  13. echo($server->handle());
  14. ?>

And this is a simple test class to call the method that returns the token for authentication

  1. <?php

  4. {

  14.    
  15.     function __construct()
  16.     {
  17.         //for LCCS

I had to implement a system to upload files that were a little different than what is typically used in Flash, with this feature had to be integrated into the Zend AMF.
Researching a little on the net, found a solution that was simpler than I thought based on that article with a few adjustments.
Begin with our gateway to be used as endpoint in Adobe Flex.

PLAIN TEXT
PHP:
  1. <?php
  2.       require_once 'Zend/Amf/Server.php';
  3.       require_once 'Zend/Amf/Exception.php';
  4.       require_once 'br/com/leonardofranca/vo/FileVO.php';
  5.       require_once 'br/com/leonardofranca/UploadZendAMF.php';
  6.        
  7.       $server = new Zend_Amf_Server();
  8.       $server->setProduction(false);
  9.        
  10.       $server->setClass('UploadZendAMF');
  11.        
  12.       $server->setClassMap('FileVO',"br.com.leonardofranca.vo.FileVO");
  13.    
  14.       echo($server->handle());
  15.       ?>

Now our VO properties with the file name and binaries.

PLAIN TEXT
PHP:
  1. <?php
  2.       class FileVO
  3.       {
  4.           public $_explicitType = 'br.com.leonardofranca.vo.FileVO';
  5.           public $fileName;
  6.           public $fileData;
  7.          
  8.           function __construct ()
  9.           {}
  10.          
  11.           public function getFileName()
  12.           {
  13.               return $this->fileName;
  14.           }
  15.        
  16.           public function setFileName($fileName)
  17.           {
  18.               $this->fileName = $fileName;
  19.           }
  20.        
  21.           public function getFileData()
  22.           {
  23.               return $this->fileData;
  24.           }
  25.        
  26.           public function setFileData($fileData)
  27.           {
  28.               $this->fileData = $fileData;
  29.           }
  30.       }
  31.       ?>

Now our PHP class to be responsible for efetudar uploading.

PLAIN TEXT
PHP:
  1. <?php
  2.       class UploadZendAMF  
  3.       {
  4.           public function __construct()
  5.           {
  6.            
  7.           }
  8.          
  9.           public function upload(FileVO $data)
  10.           {
  11.               try
  12.               {
  13.                   $fileData = $data->getFileData();
  14.                   file_put_contents( 'C:\\apache\\htdocs\\images\\' . $data->getFileName(), $fileData);//your dir
  15.                   return true;  
  16.               }
  17.               catch (Exception $e)
  18.               {
  19.                   throw new Exception($e->getMessage());
  20.               }
  21.           }
  22.       }
  23.       ?>

Now let the view layer using Adobe Flex, we start with our VO.

PLAIN TEXT
ACTIONSCRIPT3:
  1. package br.com.leonardofranca.vo
  2.       {
  3.           import flash.utils.ByteArray;
  4.        
  5.           [Bindable]
  6.           [RemoteClass(alias="br.com.leonardofranca.vo.FileVO")
  7.           public class FileVO
  8.           {
  9.               private var _fileName:String;
  10.               private var _fileData:ByteArray;
  11.              
  12.               public function FileVO()
  13.               {
  14.               }
  15.        
  16.               public function get fileName():String
  17.               {
  18.                   return _fileName;
  19.               }
  20.        
  21.               public function set fileName(value:String):void
  22.               {
  23.                   _fileName = value;
  24.               }
  25.        
  26.               public function get fileData():ByteArray
  27.               {
  28.                   return _fileData;
  29.               }
  30.        
  31.               public function set fileData(value:ByteArray):void
  32.               {
  33.                   _fileData = value;
  34.               }
  35.        
  36.           }
  37.       }

Now our mxml that will load the bytes from the file to send to the Zend AMF.

It is a resource that if properly used, it is powerful and help prevent future headaches for your system. An exception is nothing more than the possibility of treating an error without necessarily stop completely your program.
Support for exceptions was added in PHP since version 5, and may be using in conjunction with Adobe Flex, this case will use the Zend AMF, an implementation of the AMF protocol for working together with the Flash Platform and its server- side running PHP as part of ZendFramework.
It is considered a best practice you create your exception class extending the class Zend_Exception.

PLAIN TEXT
PHP:
  1. <?php
  2. class MyException extends Zend_Exception{}

For now just that is enough, we can implement more methods according to the need for our system.
Now create a class to trigger the exception, in PHP this is done using the keyword "throw".

PLAIN TEXT
PHP:
  1. <?php
  2.       class HelloException  
  3.       {
  4.            public function dispatchException()
  5.            {
  6.               throw new MyException("dispatch exception!!!");
  7.            }  
  8.       }
  9.       ?>

In Flex we usually call the method using the RemoteObject class.

PLAIN TEXT
ACTIONSCRIPT3:
  1. protected function application1_creationCompleteHandler(event:FlexEvent):void
  2.                   {
  3.                       ro = new RemoteObject();
  4.                       ro.destination = "nao faz diferença nenhuma usando com Zend AMF";
  5.                       ro.endpoint = "http://localhost:81/ZendAmf/teste_exception.php";
  6.                       ro.source = "br.com.leonardofranca.HelloException";
  7.                       ro.addEventListener(ResultEvent.RESULT, handlerResult);
  8.                       ro.addEventListener(FaultEvent.FAULT, handlerFault);
  9.                       ro.dispatchException();
  10.                   }

Our attention will turn to the FaultEvent, he is responsible for catching exceptions coming from the server. Basically just need to show the user the faultString.

PLAIN TEXT
ACTIONSCRIPT3:
  1. private function handlerFault(fault:FaultEvent):void
  2.                   {
  3.                       trace(fault.fault.faultCode);
  4.                       trace(fault.fault.faultDetail);
  5.                       trace(fault.fault.faultString);
  6.                       Alert.show(fault.fault.faultString,"Atenção");
  7.                   }

We have the following result:

Exception

Sometimes I see on the Internet some movement "anti-Flash", something really strange, it seems religion. There is a culture of saying that Flash is a program "to make a ball go" or that "Flash has accessibility zero, this is very far from the truth. it is possible to make extremely complex applications with Flash. And when there is a kind of "dispute" between AJAX X FLASH Flash x Silverlight Flash x HTML5. From time to time there is a new "Flash-killer", I think they are different technologies and complement. I see the same kind of radicalism in relation to PHP X Cold Fusion, ASP X PHP, PHP X PHYTON, Open Source X Proprietary etc.
I have also been very radical, defending PHP tooth and nail, spoke ill of any other language that was not PHP without even know it, but I realized that those who still think that way, limits their opportunities to major world today no matter what tool you use but how you use the tool, who heard "The bad employee blames his tools work"?.
Always worked with Flash and PHP, when I entered the BANCOOB, I felt compelled to learn Java, was a challenge that could overcome. Shortly after I entered the migration project, which would have to program in C # and Visual Basic, many of my friends simply do not accept into the project. I heard things like, "look at my curriculum and see if it is VB" and called the loose, but the end result was a great experience for me, I was able to grow much.
I have already been many philosophical discussions, and today I have no more patience for it when I see that this conversation tends to radicalism or religion, I lose the will to fully discuss.
Working with Flash since version 5, I followed closely the development of the tool, and the long ceased to be just a "plugin" to become a development platform for several devices. Of course with that, disrespect the competition, which is great. After all we must always move.

Developers who do not work with Flash, underestimate the power he has.

I'm not the only one who thinks this story that "one will replace the other" makes no sense, to own Adobe preaches that the two work perfectly together, so that the Adobe Dreamweaver CS5 already has support HTML5.
The launch of the iPad was the trigger for the so-called "anti-Flash". it mounted the perfect setting for a healthy discussion, where we could point out the strengths and weaknesses of a given technology and how it can be improved. But what we have seen is just the opposite, I've seen several articles and comments from people simply saying "I hate Flash", sites with sensational headlines(what they did to the post of Lee was disgusting!!!), Each week a different rumor that people believe without checking the sources and the same conversation 5 years ago.

Meanwhile, the client ta little matter if you use this tool or that, what matters to him is that you do the job.

The bad employee blames his tools work.

Zend, which maintains the PHP, have your ZendFramework, a package called ZendAMF to implement such an integration between Flex and PHP. In the hands of Wade Arnold, who also holds the AMFPHP.
If took me a while to start using this implementation, had already gotten used to het AMFPHP and made several systems with it. However, their adobe recommends the use of ZendAMF for building RIAS's with Flex and PHP.
As a first example using the ZendAMF, i will use the same database meda in the previus article about Flex and Java.
Ona advantage of Flex is designed to be the view layer, and this alllow the business layer is transparent and can user either Java, PHP or .NET, need only pointo to a different endpoint according to their need.
You can download the latest version of ZendAMF the following link. More importantly, you do note need to dowload any ZendFramework to use this packag.
Once that's done, extract the files in the directory of your choice, in my case, i created one called "ZendAMF" and make sure thath the directory contains "Zend".
The objective is not to change almost anything int the form of organization which was in AMFPHP. So to test our AMF, create a file called "gateway.php" with the following code:

PLAIN TEXT
PHP:
  1. <?php
  2. require_once 'Zend/Amf/Server.php';
  3. $server = new Zend_Amf_Server();
  4. $server->setProduction(false);
  5. echo($server->handle());
  6. ?>

Running the link in your browser, you should see the following message:

Zend Amf Endpoint

The ZendAMF are ready for our development, i tried to keep the directory structure as close as possible to what they had in java, therefore, create the following directory to our VO; br.com.leonardofranca.vo and br.com.leonardofranca for the main class. The structure should be as follows:

Zend
br/com/leonardofranca/vo
br/com/leonardofranca
gateway.php

Our VO in PHP would be as follows:

PLAIN TEXT
PHP:
  1. <?php
  2. class ContatosVO  
  3. {
  4.     public $_explicitType = 'br.com.leonardofranca.vo.ContatosVO';
  5.     public $id = 0;
  6.     public $nome = "";
  7.     public $email = "";
  8.    
  9.     function __construct()
  10.     {
  11.        
  12.     }
  13.    
  14.     public function getId()
  15.     {
  16.         return $this->id;
  17.     }
  18.    
  19.     public function setId($id)
  20.     {
  21.         $this->id = $id;
  22.     }
  23.    
  24.     public function getNome()
  25.     {
  26.         return $this->nome;
  27.     }
  28.    
  29.     public function setNome($nome)
  30.     {
  31.         $this->nome = $nome;
  32.     }
  33.    
  34.     public function getEmail()
  35.     {
  36.         return $this->email;
  37.     }
  38.    
  39.     public function setEmail($email)
  40.     {
  41.         $this->email = $email;
  42.     }
  43. }
  44. ?>

Then, our main class, which will perform the operations list, insert, delete and update data from our database:

  37.             }
  38.             return($this->dados);
  39.         }
  40.         else
  41.         {
  42.             return false;
  43.         }

  52.         '".$this->contatosVO->email."')";
  53.         $this->query = mysql_query($this->sql);
  54.         if (!mysql_error())
  55.         {
  56.             return true;
  57.         }

  66.         $this->contatosVO = $contatosVO;
  67.         $this->sql = "DELETE FROM tabela WHERE id = '".$this->contatosVO->id."' LIMIT 1";
  68.         $this->query = mysql_query($this->sql);
  69.         if (!mysql_error())
  70.         {
  71.             return true;
  72.         }
  73.         else
  74.         {
  75.             return false;
  76.         }
  77.     }
  78.    
  79.     public function updateData($contatosVO=ContatosVO)
  80.     {
  81.         $this->contatosVO = $contatosVO;
  82.         $this->sql = "UPDATE tabela SET nome = '".$this->contatosVO->nome."', email = '".$this->contatosVO->email."' WHERE id = '".$this->contatosVO->id."'";
  83.         $this->query = mysql_query($this->sql);
  84.         if (!mysql_error())

  90.             return false;
  91.         }
  92.     }
  93.    
  94. }
  95. ?>

Until now, no mystery, we have a simple class that uses a typed object, now let's edit the file "gateway.php" so you can call our vo and implementation class:

PLAIN TEXT
PHP:
  1. <?php
  2. require_once 'Zend/Amf/Server.php';
  3. require_once 'br/com/leonardofranca/vo/ContatosVO.php';
  4. require_once 'br/com/leonardofranca/Contatos.php';
  5.  
  6. /** Bootstrap */
  7.  
  8. // Instantiate server
  9. $server = new Zend_Amf_Server();
  10. $server->setProduction(false);
  11. //$server->addDirectory('services/');
  12. // reflection
  13. $server->setClass('Contatos');
  14. $server->setClassMap('ContatosVO',"br.com.leonardofranca.vo.ContatosVO");
  15. // Handle request
  16. echo($server->handle());
  17. ?>

Added the call our implementation class and mapped the vo, done that, let's the hardest part now :P ,
got the same mxml file of the previous articles and modify the following line:

PLAIN TEXT
MXML:
  1. <mx : RemoteObject id="ro" destination="zendamf" source="br.com.leonardofranca.Contatos" endpoint="http://localhost/ZendAmf/gateway.php">
  2. <!-- <mx : RemoteObject id="ro" destination="blazeds" source="br.com.leonardofranca.Contatos" endpoint="http://localhost:8080/Contatos/messagebroker/amf"> -->

Moreover, i did not change anything in programming in Fle, the objective here was to show a simple way, how we can have a view layer rich with Adobe Flex, regardless of the business layer.

In later versions of ZendAmf, you nedd some packages contained in ZendFramework, one option is to go adding the packages in your project or use any ZendFramework.

Now we go to our archive in Flash, remembering that it only will contain the codes, the components (generated dinamicamente script saw action) will have to be in the library of the swf.
We will dinamicamente create dinamicamente the fields of text and the buttons, using the method createClassObject, being necessary to specify the way of the component.
For example to create a button dinamicamente.

PLAIN TEXT
Actionscript:
  1. _root.createClassObject(mx.controls.Button, "Button", 1);

One another way to make this would be to import the classrooms of the component in the start of script.

Actionscript:
  1. import mx.controls.Button;

and in metodo

PLAIN TEXT
Actionscript:
  1. _root.createClassObject(Button, " Button ", 1);

The second argument will be the name of the instancia of the object created in the case “Button�
Understood as the components they are created dinamicamente, we will need that when the option of datagrid will be clicked, that it appears in the fields of texts to be brought up to date or excluded. For this we will add to an object listener who listens to ours datagrid. We will make this of the function inside user_Result.

PLAIN TEXT
Actionscript:
  1. var listenerObject:Object = new Object();

creating the function that to respond to the object listener, in it we will catch the option that will be chosen in datagrid to fill the fields of texts , it notices that id of datagrid will be stored in an variable to be later used in the metodos to bring up to date and to exclude the information of the database . We are including the actions (onRelease) that they will be used in the buttons to bring up to date and to exclude the registers . It notices that it is not being enclosed the action of the button to insert therefore will not depend on datagrid.
When the button to bring up to date will be clicado it will order for the server the parameters that will be in the field of text and the variable “id� for method updateRecords(id, campo_nome.text, campo_email.text, campo_tel.text); (the same for exclusion ) e for I finish adding to everything this datagrid with the method addEventListener("change", listenerObject);

PLAIN TEXT
Actionscript:
  1. listenerObject.change = function(evt) {
  2. var id:Number = evt.target.selectedItem.id;
  3.         campo_nome.text = evt.target.selectedItem.nome;
  4.         campo_email.text = evt.target.selectedItem.email;
  5.         campo_tel.text = evt.target.selectedItem.telefone;
  6.         trace(evt.target.selectedItem.id);
  7.         bot_update.onRelease = function() {
  8.             var pcs:PendingCall = conexao.updateRecords(id, campo_nome.text, campo_email.text, campo_tel.text);
  9.             pcs.responder = new RelayResponder(_root, "updateRecords_Result", "updateRecords_Fault");
  10.         };
  11.         bot_excluir.onRelease = function() {
  12.             trace(id);
  13.             var pcs:PendingCall = conexao.delRecords(id);
  14.             pcs.responder = new RelayResponder(_root, "delRecords_Result", "delRecords_Fault");
  15.         };
  16.     };
  17. grid.addEventListener("change", listenerObject);

will also use the component “Alert� to confirm that the insertion, update and exclusion of a register were made successfully. It will be called inside the functions setRecords_Result, updateRecords_Result and delRecords_Result, being that as soon as ok of alert will be clicado the button, will be invoked the method update_Dg that datagrid will bring up to date the data of ours.

PLAIN TEXT
Actionscript:
  1. var dialog_obj:Object = Alert.show("Sucess", "Sucess!!!", Alert.OK, null, update_Dg);

In this article we are going to create a RIA application more elaborated than a “Hello World�?, and you can use it in you real world application.

You need knowledge about PHP, MySQL, Flash and Flash Remoting.

First, we create a simple database structure, only with name, e-mail and telephone number. Let’s create the table and insert some data:

PLAIN TEXT
SQL:
  1. ##create the user table
  2.     CREATE TABLE `users` (
  3.     `id` int(4) UNSIGNED NOT NULL AUTO_INCREMENT,
  4.     `name` char(80) DEFAULT NULL,
  5.     `email` char(100) DEFAULT NULL,
  6.     `telephone` char(10) DEFAULT NULL,
  7.     PRIMARY KEY (`id`)
  8.     ) ENGINE=MyISAM ;
  9.     ##insert some data in the database
  10.     INSERT INTO `users` VALUES ('’,'John’,'john@example.org’,'1234567′);
  11.     INSERT INTO `users` VALUES ('’,'Henry’,'henry@example.org’,'2234567′);
  12.     INSERT INTO `users` VALUES ('’,'Carl’,'carl@example.org’,'3234567′);
  13.     INSERT INTO `users` VALUES ('’,'Leo’,'leo@example.org’,'4234567′);
  14.     INSERT INTO `users` VALUES ('’,'Wendel’,'wendel@example.org’,'5234567′);

We have our user table in the database, now we create a AMFPHP class that connect with our database and return data for Flash.

PLAIN TEXT
PHP:
  1. <?php
  2.      class query{
  3.           var $host = "localhost";
  4.           var $user = 'root';
  5.           var $database = 'seubanco';
  6.           var $pass = 'suasenha';
  7.           function query(){
  8.               $this->methodTable = array(
  9.               "get_user"=>array(
  10.               "description"=>"populando nosso datagrid",
  11.               "access"=>"remote"
  12.               )
  13.               );
  14.               $this->conexao = mysql_pconnect($this->host,$this->user,$this->pass);
  15.               mysql_select_db($this->database);
  16.           }
  17.        
  18.           function get_user(){
  19.               $query = mysql_query("SELECT * FROM users");
  20.               if (!mysql_error()) {
  21.                   return $query;
  22.               }else {
  23.                   return mysql_error();
  24.               }
  25.           }
  26.   }
  27. ?>

At this point, all right, now let’s go create the Flash. Open a new document, we use only one layer and one frame for importing all necessary classes from Flash Remoting.

PLAIN TEXT
Actionscript:
  1. //classes do Flash Remoting
  2. import mx.remoting.Service;
  3. import mx.services.Log;
  4. import mx.rpc.RelayResponder;
  5. import mx.rpc.FaultEvent;
  6. import mx.remoting.DataGlue;
  7. import mx.rpc.ResultEvent;
  8. import mx.remoting.PendingCall;
  9. import mx.remoting.RecordSet;
  10. // creating a connection with Flash Remoting to AMFPHP.
  11. // Add in the address of you PHP Server, with the class:
  12. var conexao = new Service("http://localhost//flashservices/gateway.php", new Log(), "query", null, null);
  13. // Calling the method get_user()
  14. var pcs:PendingCall = conexao.get_user();
  15. pcs.responder = new RelayResponder(this, "user_Result", "user_Fault");
  16. function user_Result(res:ResultEvent) {
  17.     var grid = _root.createClassObject(mx.controls.DataGrid, "dg", _root.getNextHighestDepth(), {_x:20, _y:20});
  18.     grid.setSize(400, 350);
  19.     grid.dataProvider = res.result;
  20. }
  21. function user_Fault(fault:FaultEvent) {
  22.     trace(fault.fault.faultstring);
  23. }

All finished, you may asking, and the DataGrid? Where is? They must be in the movie or not? The answer is No. Because she will be created dynamically by the following line:

PLAIN TEXT
Actionscript:
  1. var grid = _root.createClassObject(mx.controls.DataGrid, "dg", _root.getNextHighestDepth(), {_x:20, _y:20});

The DataGrid will be created with instance name “dg�? and in the position x=20 and y=20. So, in the next step is determinated the DataGrid size with setSize().

The only one requisite is that the DataGrid must be in the movie library. “One moment, but if I want to show only some fields in the DataGrid?�? You can use two method for this, the first is using action script (hard method) and second is using the following method on AMFPHP class:

PLAIN TEXT
PHP:
  1. $query = mysql_query("SELECT name,email FROM users");

In the next articles we show you how to implement a application to insert, edit and delete data in you database, and how to configure you layout and headers of the DataGrid.
