Tasting the mix of Flex, PHP and SAP

[former_member182779]

After reading Matthias Zeller excelent blog [Engaging User Interfaces with Adobe Flex | Engaging User Interfaces with Adobe Flex] I start my Flex learning process...So yes...I have studied Flex for the last 10 days or less...Anyway...I have come to learn and really love Flex...It's simple, nice and productive.

I download this awesome Module Flex Module for Apache and IIS in order to test my Flex experiments on my Apache Server.[
| http://labs.adobe.com/wiki/index.php/Flex_Module_for_Apache_and_IIS]

As I usually do when I first learn a new Scripting Language, I have developed a SE16 Emulator by using Flex, PHP and SAP...I know that you might be asking yourselfs..."Did Blag said PHP? Why?"...It's fair simple...I can't use WebServices on my laptop's MiniSAP 4.6D so I needed a way to connect to SAP and pass the information to Flex.

What we need to do? We must create a Login Class...

Login_Class.php

<p>Class Login{var $Login, $rfc;function Log_In($Server,$Sysnum,$Client,$User,$Pass){$this->Login = array ("ASHOST"=>$Server,                      "SYSNR"=>$Sysnum,                      "CLIENT"=>$Client,                      "USER"=>$User,                      "PASSWD"=>$Pass,                      "CODEPAGE"=>"1404");return $this->Login;}function RFC_Connection($Login){$this->rfc = saprfc_open($Login);   IF ( !$this->rfc )   {       ECHO "The connection fails with the following error:".saprfc_error();       EXIT;   }   else   {       return $this->rfc;   }}}?></p>

We need an Index php page too...

index.php<br />

<textarea cols="90" rows="20"><?php

session_start();

include("Login_Class.php");

$_SESSION["Server"] = $_POST["myServer"];

$_SESSION["Sysnum"] = $_POST["mySysnum"];

$_SESSION["Client"] = $_POST["myClient"];

$_SESSION["User"] = $_POST["myUser"];

$_SESSION["Pass"] = $_POST["myPassword"];

$Login = new Login();

$Log_Me =  $Login->Log_In($_SESSION["Server"],$_SESSION["Sysnum"],

             $_SESSION["Client"],$_SESSION["User"],$_SESSION["Pass"]);

$RFC_Me = $Login->RFC_Connection($Log_Me);

if(isset($RFC_Me))

{

     $Return = "<connections><connection>

                  <value>Connected</value>

                  </connection></connections>";

     print($Return);

}

else

{

$_SESSION = array();

session_destroy();

$Login = new Login();

$Login->Login_Page();

}

?>

</textarea>

</p><p>Now, we can build our UI in Flex.

</p><p>index.mxml

browser.mxml<br />

<textarea cols="90" rows="20"><?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns="*"

layout="horizontal">

<mx:HTTPService id="userRequest"

useProxy="false" method="POST">

     <mx:request xmlns="">

          <myTable>{myTable.text}</myTable>

     </mx:request>

</mx:HTTPService>

<mx:Form>

<mx:Panel x="10" y="10" title="SE16 Emulator"

width="775" height="400" layout="absolute">

     <mx:Label x="60" y="10" text="Table" />

     <mx:TextInput x="110" y="10" id="myTable" text=""/>

     <mx:Button x="280" y="10" id="ShowData" label="Show Data"

     click="userRequest.send()"/>

     <mx:DataGrid id="dgData" x="20" y="40" height="300" width="710"

     dataProvider="{userRequest.lastResult.tables.table}">

          <mx:columns>

               <mx:DataGridColumn headerText="{userRequest.lastResult.connections.     

               connection.value}" dataField="data"/>

          </mx:columns>

     </mx:DataGrid>     

</mx:Panel>

</mx:Form>

</mx:Application>

</textarea>

</p><p>In order for this to work, we need to create our last php page...
