I got 2 questions on (Flash Builder 4.5 for PHP) autogenerated classes and authentication via AMF.

1) As I understood, the authentication should be set up manually on the PHP side, for instance right in the gateway.php, just before the ‘handle’ call:

// create server
$server = new Zend_Amf_Server();
$server->setProduction(false);

// auth
$authAdapter = new My_Custom_Auth_Adapter();
$server->setAuth($authAdapter);

// acl
$acl = new Zend_Acl();
$server->setAcl($acl);

// handle AMF request
echo $server->handle();

Now, I know about implementin initAcl($acl) method inside each service class, and it works fine.
However, I’ve got the problem with auth. My_Custom_Auth_Adapter never gets called.
I think it’s because at this state I’ve got no credentions sent from Flex through the wire (via headers).
I expected that the methods shouldn’t be called if there are no credentials, but they somehow are.
Now check this out:

Server.php (Zend_Amf_Server) line 499:

$handleAuth = false;
if ($this->_auth) {
$headers = $request->getAmfHeaders();
if (isset($headers[Zend_Amf_Constants::CREDENTIALS_HEADER]) &&
isset($headers[Zend_Amf_Constants::CREDENTIALS_HEADER]->userid)) {
$handleAuth = true;
}
}

… seems like the auth is handled only if there are credentials sent from Flex. Meaning that one can skip auth with no headers sent (?)

2) now for the client. Do you know how am I supposed to supply the credentials to AMF call?
Is it on each call?
Or is it one per session?

This is the best I know, but it doesn’t help: http://forums.adobe.com/thread/840942?decorator=print&displayFullThread=true

Thank you.

Your series of blogs are very helpful. One question: is Cairngorm framework able to fit into this picture smoothly? Theoretially Cairngorm is client side framework, it should be independent of what you discussed here, just want to see how it works practically, or should we use it with FlashBuilder4 at all?

How do I go about changing the records for a specific field?

@Kash, Anna
Hi, I dont know if you found the answer but I think you dont have access to your web root. In “my computer” the drive must be accessible, ie. you should be able to connect to D:\78963\www\mydomain\

My servers are in linux enviroment so i set up samba and mount webroot as network drive for my dev server.
So http://www.mydomain.com is simply z:\
I am sure you can do a similar setup in windows servers.

This only works for local WAMP/MAMP configuration. If I try to enter external server info (Web root and root URL), the configuration fails validation. For example, my external server web root absolute path is “D:\78963\www\mydomain\” and the root URL is “http://www.mydomain.com”.

Any suggestions?

this is my first flex application and i m trying to make a login form using wsdl. My wsdl return string called “Success” if the user name and password is correct.
I call the web service at the click of submit button
when i try to get the return value into a variable for eg:

var info:String = service.lastResult

i always get a null value at first. When i click for the second time, it returns the string.
I m not able to understand. Please help.

Thanks in advance,

2. Why implementation is only possible with wizard and zend framework? Is it not MUCH better to provide something like a DATA PROVIDER with parameters startIndex, maxElements, callbackFunction?

Once you see data in your data grid you should have a value for event.itemRenderer.data different than null.

I have been tracing in the debugger since I see data and event.itemRenderer.data is returning null

Joel

From what you are saying I understand that you don’t see any data on the client. If you’d see data then event.itemRenderer.data wouldn’t be null.

So, the first step would be to fix any problem you have in order to see data (problems could be on the PHP side, like incorrect database credentials).

After you see data, use the Flex debugger to see if the itemRenderer.data object has the type you expect. If the mapping from the PHP to ActionScript type is not correct, you’ll get instances of ProxyObjects and not VOObject.

I actually had a problem with Flex 4 based ont his tutorial. I’ve been struggling with it for hours. In the editedData function I trace event.itemRenderer.data and the value is null. I assign VOObject = event.itemRenderer.data AS VOObject and trace(VOObject) and the value is null. I’m really stuck at this step and I’d like to get some sleep soon, please help!

1067: Implicit coercion of a value of type services.authors:VOAuthor to an unrelated type valueObjects:VOAuthor. flexPHPAMF.mxml flexPHPAMF/src line 25 Flex Problem

this refers to:
authors.saveData(vOAuthor);

any ideas?

For the Web Root set the path to the PHP web server root (where the PHP files stay on your server).
For the Root URL set the URL to reach the Web Root (usually this is http://localhost)
For the Output folder location set the same path as the one for Web Root and add flexPHPAMF-debug.

These should work.

You mean like a search? It’s simple, you just have to create a search method in the PHP class, and then in Flex to add a textbox and a button in order to fill in the search criteria and start the search.

Great example; I have a question that I have not been able to figure out: your example as some others return all the records, how would one go about adding the code that would allow to return the records from a specific field where the data matched some user input from a text box?

Joel

not at all. you can use any kind of PHP installation.

Is a localized server environment, such as MAMP, required to setup the PHP data/service? I can’t for the life of me figure this out. All examples that I have found are using either MAMP or WAMP. What if you want to accomplish this on a production server?

Thanks in advance for any insight.
