Flex & PHP Tutorial - Transmitting data using JSON

To make sure we don't get too stuck in a rut with our tutorial posts I decided to branch out a little bit and talk about Adobe Flex 2.0. I recently spent a lot of time figuring out how to do this. Basically what I am going to go over here is how to use php and json to send data to your flex application, and then how to use that data in Flex.

This is actually a lot easier than it seems because PHP and Flex both have functions to handle json data transmissions. For Flex, the one thing you need to make sure is that you have the corelib from Adobe in order to use the JSON functions - this can be found at Adobe Flex coreLib. This can be added to a project in Flex builder by going into the properties of a project then to "Flex Build Path" and adding the .swc to the library path. For PHP, if you have a version greater than 5.2, you are all set. If not, you can either upgrade, or install the php-json extension.

Below is the final product of what we are going to create today - to view the Flex source right click the flash movie and select 'View Source'. Pressing each of the buttons sends a request to our php code for data. If you click the "Get Employee" button we just get a single person back, and if you click "Get Manager" we get a manager back and his employees (which is an array of people). This is a very simple little app, and not particularly useful, but it does have everything needed to show how to communicate between php and flex using json.

The first thing we are going to go over is the php code. The php code creates a few classes for the objects that we will pass to our flex application. We also have code to check if a GET variable has been set, we use this to tell the php code what we are requesting. If the variable "getPerson" is set we create a person and echo it (after we encode it into json) to send it to the Flex app. Ideally your data would be stored in a database, but for simplicity, we're just creating Person objects directly in the php code.

<?php

class Person
{
public $first_name;
public $last_name;
public $email;
public $address;
}

class Manager extends Person
{
public $title;
public $employees;
}

if(isset($_GET['getPerson']))
{
$p = new Person();
$p->first_name = 'Chuck';
$p->last_name = 'Killer';
$p->email = 'fake@email.com';
$p->address = '5555 Some Street City, State 52423';
echo json_encode($p);
}

if(isset($_GET['getManager']))
{
$p1 = new Person();
$p1->first_name = 'Joe';
$p1->last_name = 'Schmoe';
$p1->email = 'joe.schmoe@email.com';
$p1->address = '5424 Some Street City, State 12314';
$p2 = new Person();
$p2->first_name = 'Bob';
$p2->last_name = 'Hacker';
$p2->email = 'bob.hacker@email.com';
$p2->address = '1414 Some Street City, State 12412';
$p3 = new Person();
$p3->first_name = 'Kevin';
$p3->last_name = 'Putvin';
$p3->email = 'kevin.putvin@email.com';
$p3->address = '6123 Some Street City, State 41241';
$m = new Manager();
$m->first_name = 'Manager';
$m->last_name = 'Dude';
$m->email = 'manager.dude@email.com';
$m->address = '5534 Some Other Street City, State 91230';
$m->title = 'Office Manager';
$m->employees = array($p1, $p2, $p3);
echo json_encode($m);

}
?>

The next thing to do is setup the basic application for flex. The following code is the simplest flex application. This sets up an application with specified height and width and also adds the view source option to the movie, with the source file specified by "viewSourceURL".

The next thing to do is setup the user interface. This is pretty standard flex mxml, nothing should look out of place. The user interface has a couple of text fields for the data we get back from the php code, a datagrid, and two buttons. This is all setup on a panel. The one important thing to observe is that the dataField properties on the DataGridColumns, these names correspond to the variables from the objects in the php code.This code goes inside the Application block.

<mx:Panel x="0" y="0" width="500" height="410" layout="absolute"
title="Simple JSON Example">
<mx:DataGrid x="10" y="174" width="460" enabled="true"
editable="false" id="dgEmployees">
<mx:columns>
<mx:DataGridColumn headerText="First Name"
dataField="first_name"/>
<mx:DataGridColumn headerText="Last Name"
dataField="last_name"/>
<mx:DataGridColumn headerText="Email"
dataField="email"/>
<mx:DataGridColumn headerText="Address"
dataField="address"/>
</mx:columns>
</mx:DataGrid>
<mx:Button x="116" y="338" label="Get Employee"
id="getPerson" />
<mx:Button x="266" y="338" label="Get Manager"
id="getManager" />
<mx:Label x="131" y="12" text="Name"/>
<mx:TextInput x="189" y="10" id="txtName" editable="false"/>
<mx:Label x="131" y="42" text="E-mail"/>
<mx:TextInput x="189" y="40" id="txtEmail" editable="false"/>
<mx:Label x="131" y="68" text="Address"/>
<mx:TextInput x="189" y="66" id="txtAddress"
editable="false"/>
<mx:Label x="131" y="94" text="Title"/>
<mx:TextInput x="189" y="92" id="txtTitle" editable="false"/>
<mx:Label x="131" y="122" text="Has Employees"/>
<mx:TextInput x="229" y="120" width="120" editable="false"
id="txtEmployees" text="No"/>
<mx:Label x="10" y="148" text="Employees:"/>
</mx:Panel>

Now that our user interface is setup and ready to go we can add our http services to go ask for the data from our php code. Now in flex you can setup all kinds of different services. We are just going to setup a simple http request service that sets a GET variable and tells the service that we want to run a function once we get the results. As you can see in the code below we send both services out to the same php page, which is the one we made earlier. Also each one sets one GET variable, which is done inside the mx:request block. Lastly, the result is an event which we hook to, to process the results of the request (our JSON data). This code goes at the very beginning of the file right after the Application opening element.

<mx:HTTPService id="personRequest"
url="../files/json_tutorial.php"
useProxy="false" method="GET" resultFormat="text"
result="personJSON(event)">
<mx:request xmlns="">
<getPerson>"true"</getPerson>
</mx:request>
</mx:HTTPService>
<mx:HTTPService id="managerRequest"
url="../files/json_tutorial.php"
useProxy="false" method="GET" resultFormat="text"
result="managerJSON(event)">
<mx:request xmlns="">
<getManager>"true"</getManager>
</mx:request>
</mx:HTTPService>

Ok, now let's get into the actual JSON decoding, which is really simple. So at this point if your using flex builder you will be getting a error message about an undefined method for personJSON(event) and managerJSON(event). We are going to solve that right now. First things first - lets just put in the method signatures so the application can build and run. The way this is done is by inputting a script tag and adding our actionscript functions inside there. You'll notice we added two import statements to import our JSON serialization functions and use the result event. This code will go right above the http services we just setup and below the Application opening element.

<mx:Script>
<![CDATA[
import mx.rpc.events.ResultEvent;
import com.adobe.serialization.json.JSON;

private function personJSON(event:ResultEvent):void
{
}

private function managerJSON(event:ResultEvent):void
{
}
]]>
</mx:Script>

Now down to the actual work of our application, the first thing we need to do in both of the functions is get the result back and we store it in a string. The next thing we do is call the function JSON.decode on the string, this function will return us an object with all the same properties of the one sent by php - we set this equal to a variable. We can now use this object and reference the properties using the . (dot) notation. So to get the first name of the person we simply use variable.first_name and so on for the rest of the variables. So that takes care of getting a person. And the above code is changed like so.

<mx:Script>
<![CDATA[
import mx.rpc.events.ResultEvent;
import com.adobe.serialization.json.JSON;

private function personJSON(event:ResultEvent):void
{
//get the raw JSON data and cast to String
var rawData:String = String(event.result);
var person = JSON.decode(rawData);
txtName.text = person.first_name + " " +
person.last_name;
txtEmail.text = person.email;
txtAddress.text = person.address;
txtEmployees.text = "No";
txtTitle.text = "No Title";
}

private function managerJSON(event:ResultEvent):void
{
//get the raw JSON data and cast to String
var rawData:String = String(event.result);
var manager = JSON.decode(rawData);
txtName.text = manager.first_name + " " +
manager.last_name;
txtEmail.text = manager.email;
txtAddress.text = manager.address;
txtEmployees.text = "Yes";
txtTitle.text = manager.title;
}
]]>
</mx:Script>

This takes care of all the text boxes we created and puts the correct values in them. Now we have to worry about that datagrid we created, and you might have noticed we haven't dealt with the employees of the manager yet. Well this is handled pretty nicely in the manager function. We are going add a new var called employees and this will be an Array. Because of the JSON.decode function we can simply cast the employees as an Array and all will be fine. The next thing we do is actually create an ArrayCollection to use for the data provider for the datagrid. This is a best practice when using array data for the provider because the ArrayCollection allows for some extra functionality. The final setup is to set the dataGrid.dataProvider equal to the ArrayCollection. Also we set the dataProvider equal to null in the person function to clear our the data in the data grid. To make all this work we also need to add another import for ArrayCollection. This leaves us with the following code.

<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
import mx.rpc.events.ResultEvent;
import com.adobe.serialization.json.JSON;

private function personJSON(event:ResultEvent):void
{
//get the raw JSON data and cast to String
var rawData:String = String(event.result);
var person = JSON.decode(rawData);
txtName.text = person.first_name + " "
+ person.last_name;
txtEmail.text = person.email;
txtAddress.text = person.address;
txtEmployees.text = "No";
txtTitle.text = "No Title";

//Data Grid Code
dgEmployees.dataProvider = null;
}

private function managerJSON(event:ResultEvent):void
{
//get the raw JSON data and cast to String
var rawData:String = String(event.result);
var manager = JSON.decode(rawData);
txtName.text = manager.first_name + " "
+ manager.last_name;
txtEmail.text = manager.email;
txtAddress.text = manager.address;
txtEmployees.text = "Yes";
txtTitle.text = manager.title;

//Data Grid Code
var employees:Array =
manager.employees as Array;
var employeesCollection:ArrayCollection =
new ArrayCollection(employees);
dgEmployees.dataProvider = employeesCollection;
}
]]>
</mx:Script>

Now you might have tried it at this point and said "Hey, this isn't working!", well that is true. This is because we never hooked our buttons up to send the requests. This is really simple, we just add click events for both buttons and the corresponding service.send() commands to the click events. The code below is our new button code.

<mx:Button x="116" y="338" label="Get Employee"
id="getPerson" click="personRequest.send();"/>
<mx:Button x="266" y="338" label="Get Manager"
id="getManager" click="managerRequest.send();"/>

So this leaves us with the final flex code. This along with the php code at the beginning of the tutorial allows for JSON data to be sent to your flex applications.

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="absolute" width="500" height="410"

//get the raw JSON data and cast to String
var rawData:String = String(event.result);
var person = JSON.decode(rawData);
txtName.text = person.first_name + " "
+ person.last_name;
txtEmail.text = person.email;
txtAddress.text = person.address;
txtEmployees.text = "No";
txtTitle.text = "No Title";

//Data Grid Code
dgEmployees.dataProvider = null;
}

private function managerJSON(event:ResultEvent):void
{
//get the raw JSON data and cast to String
var rawData:String = String(event.result);
var manager = JSON.decode(rawData);
txtName.text = manager.first_name + " "
+ manager.last_name;
txtEmail.text = manager.email;
txtAddress.text = manager.address;
txtEmployees.text = "Yes";
txtTitle.text = manager.title;

//Data Grid Code
var employees:Array =

Hi,

Thanks for your article, I was looking for make an RPC with Flex and PHP (using symfony framework) and now it works really good !

There is the code I used for calling a symfony action (MVC pattern …) with some argument (arg0 is for identification) :

public function invoke (url:String, callback:Function, args:Array = null):void
{
var loader:URLLoader = new URLLoader();
configureListeners(loader);

// Prepare arg string
var argString:String = “?arg0=security_code”;

if (args != null) {

// Match ob_name needed with data loaded
args.forEach(function (item:String, index:Number, arr:Array):void {

argString += “&arg” + (index+1) + “=” + item;

});

}

var request:URLRequest = new URLRequest(”../” + url + argString);

this.callback = callback;

request.method = URLRequestMethod.POST;
loader.load(request);
}
————————————-
myRPC.invoke(”object/delete”, onResult, [3, ‘Laura’]);

private function onResult(result : Object, status:int) : void
{
if (result != “OK”) {
Alert.show(result as String, “Message”);
}
}

Hope its can be useful !

Thanx to Fastest for the nice tutorial.Is there any way I could do the opposite of what u have done.By this am and have been trying for some time to send an array of actionScript class object to PHP.
This is what i mean
Person.as is an AS class
In the same Flex project I have the main MXML file that has an array of Person objects declared like this:
var people:Array = new Array()
Finally I would like to send this entire array to a PHP script
Thanx in advance
Mine is not working, i get the following error Says:

Mr Mine,
Here is what I would suggest. First, go to the php page that your pulling data from directly from your browser. So in our case it would be http://blog.paranoidferret.com/files/json_tutorial.php?getPerson=true
this should return some JSON encode data, and you will be able to see this in the browser window. If the data isn’t showing up the problem lies in the php code. If it does show up then the next step I would suggest is to run the debugger on your flex with a break point right before you call JSON.decode; now you can check out what event.result is set to. If these suggestions don’t help out, let me know and at that point I will have to see some code.

Is using cold fusion easier?
The Fattest Says:
December 3rd, 2007 at 9:20 am
Mike,
Using cold fusion is probably easier, but I can’t say for sure because I’ve never used cold fusion. From what I’ve heard Flex/Actionscript are tightly integrated with cold fusion so this task would probably be easier.

The Fattest Says:
December 7th, 2007 at 1:17 pm
My spanish is not as good as it used to be but the error is simple to fix and really should show up as a warning.

Use:
var persion:Object = JSON.decode(rawData);

That should take care of it.

hei thanks for this tutorial. it will save a lot of time cos i’ve been parsing xmls all the time!!!

i imported the .swc of corelib 0.90, using Flex Builder 2.0.1, php 5.2.3 and running the test on localhost. and i am doing everything as you said (as far as i know).

first i got the “Error #2148: ” that says that “Only local-with-filesystem and trusted local SWF files may access local resources”

i tried correcting this by adding “-use-network=false” to the flex compiler proyect properties.

But then the error is

Error: Unexpected
Javlae Says:
January 30th, 2008 at 9:07 am
Error: Unexpected
Javlae Says:
January 30th, 2008 at 9:11 am
Ok this is not working!

Error: Unexpected (less than character) encountered
at com.adobe.serialization.json::JSONTokenizer/parseError()
at com.adobe.serialization.json::JSONTokenizer/getNextToken()

from the JSONToken.as

i think this is because by adding the line i added, php is simply not working and the parser is reading the first ‘(less than)’ char from the php file: ‘(less than character)?php’

Is there another way to correct the error? do i HAVE to test it online? Why doesn’t it work on localhost?

Thanx for taking the time to do great stuff for all of us rookies!

and sorry for so many posts but this sign is kinda tricky

HI, I have problems transmitting UTF-8 characters form Flex to php. I am getting some sort of wired characters. I don’t know what’s that for. Is it from JSON encode function in Flex, or it’s from flex. Can someone help me, its very important.
Please,
Best greetings,
Dragan
The Fattest Says:
February 2nd, 2008 at 5:25 pm
Javlae,
Yes the php code needs to be running on a php server, this could be a local server but you need to make sure you’re using the correct url for your localhost.

Dragan,
It looks like PHP’s json_encoding doesn’t utf8 encode the data before sending it. I would recommend running any strings with special characters through PHP’s utf8_encode before json encoding.

For going from Flex to PHP you probably want to base64 encode the string with the special characters in Flex and then decode then in PHP. So this would look something like this:

var be:Base64Encoder = new Base64Encoder();
var s:String = “Däoeö”;
s = be.encodeUTFBytes(s)

and now s is your new value string. Does this make sense? If not I will write up a quick sample to illustrate this.

It is the same article. The guy in the picture is The Fattest. Adobe contacted us about publishing a couple of our Flex tutorials in their developer center. Here’s one of our posts explaining it a little more.
