Happy New Year Wade,

I thoroughly enjoyed your webcast on the framework last year and have begun a port of our application from AMFPHP to Zend.

Alas,

I’m stuck at something (likely trivial) and would appreciate a pointer on where to seek help.

Following the Zend setup and get Apache error…

client denied by server configuration: C:/Program Files/Apache Software Foundation/Apache2.2/htdocs/QuickStart/public/.htaccess

I’ve added

LoadModule rewrite_module modules/mod_rewrite.so
RewriteEngine on

and

Options Indexes FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all

to httpd.conf to no avail

A point in the right direction – or the forum to post on would be most appreciated.

Sincerely,

David Priest

Wade,
The webcast was great. Thanks for you hard work with AMFPHP and Zend_AMF. Is there a log of the question and answers for the webcast? I can’t remember your response to my question about AMFEXT. Are there any plans for Zend to work on a new AMFEXT? And is the current AMFEXT compatible with Zend_Amf. I apologize for the repetition here but I’m not sure you remember me asking the question.

Thank You.

That is fantastic. Thanks!

Hi Wade,
I’m having a problem to send AS class object (this class doesn’t have mapping on PHP side) it is only mapped in AS [RemoteClass(alias="MyClass")].

It works the other way if I return from PHP I just receive dynamic object on Flerx side. Can it be done the other way around?

Best,
Piotr

Hi Wade,

Thanks for the great work on Zend_Amf and AMFPHP.
I’m having to update a project that was built some time back in AS1 using Adobe’s (Macromedia then) Remoting framework for AS1. I’ve been able to port my (old) AMFPHP code across to seemingly work with Zend_Amf but haven’t as yet worked out how I can have my mysql results typed as AMF0 RecordSet’s. I know that AMFPHP simply created an associate array or object using an adapter – is there any way built in to Zend_Amf to achieve the same or do I need to emulate the AMFPHP adapter?
Thanks in advance for any help you can offer.
Cheers

Hi.
Can I use Zend_Amf together with Flash Media Server, doing remote calls serverside? FMS have a NetConnection-class that should do the trick. I have found a few articles about FMS and AMFPHP, but none about Zend_Amf. Would be nice to know if/how this is possible to do, before i use several hours just trying, having no clue at all.

Thanks again.

Hi Wade,

I am developing a Flex/Zend Framework website. For compatibility reasons, the home page is in XHTML and I’m loading the Flex swf in the background, using the htmlFlash ZF Helper. Unless I disable the server calls, Flash Player returns an unknown file type error.

My server being at mysite.com/remote , for each call a text file called ‘remote’ is returned . This seems to create the problem wit FP 10.

Is there any way to append a file extension name to the text file returned by Zend Amf?

If I load the site directly in Flex, the problem doesn’t happen, I could also make the calls after the Flex page is accessible but both solutions defeats the purpose of preloading the content within the HTML page.

Any ideas?

Thanks !

Patrick

Hi Wade,

Oops, sorry, wrong culprit, nothing to do with Zend Amf!…

Best!

Any chance you could do an updated tutorial on connecting zend with Flash? Lee’s code doesn’t work anymore as there must have been some changes to the framework from 1.6 to 1.7.

Now that I have switched from amfphp this interesting fileupload concept comes up

http://gertonscorner.wordpress.com/2009/03/15/fileupload-using-amfphp-remoteobject-and-flash-10/

A simple tutorial uploading file(s) with zend_amf using the zend framework would be great!

Hi Wade,

one question about ZendAMF and the integration of Flex (AS3) with PHP5.
What is the sense of definining Value Objects in PHP and perform all the explicit class mapping with AS3 classes, when type checking is not enforced anyways?

Example: I create a Contact object in PHP, add some non-member variables and send it via ZendAMF to Flex. There it will still be recognised as a valid Contact object.

In addition, the setClassMapping method does not care if the Flex and PHP Object actually looks alike.

Is there a function, which checks if an object really only defines member defined in the class (PHP and AS3)?

Otherwise I dont understand the whole concept of binding the classes, when I am anyways able to send whatever I want an the serialized object will comply (whatsoever it contains) as a valid object.

Thanks,
Martin

Hi Wade,

Thanks to your wonderful work, I have been able to communicate between flash and php. I am running into a couple of problems and was hoping you could give me some insight on what to do.

I am using zend_db_table to interact with my database. To do things like insert, I need to pass in an array. Since flash suggests to use objects I have been passing into php objects and type casting them to arrays. This works if everything is perfect, but I am also validating the parameters – php does the validation for the front end of the flash app to report. I am using Zend_filter_input for the validation.

My original thought was to throw errors and pass back the zend_filter_input error array to flash. In flash I get the NetConnection.Call.BadVersion when I throw an exception and am passing in an object (and meet the criteria for an exception to be thrown).

I couldn’t get around this so my next thought was to pass back an object to flash as a normal return, but flash is not able to parse through the object (I’m guessing it doesn’t receive it correctly).

So lastly I attempted to do a classMap, but my poor knowledge of flash as3 has hindered me sorely. All the examples with class mapping are in flex and I can’t seem to make the adjustment for flash.

Any help on the matter would be greatly appreciated. I’ve been banging away at this, and I get the sense that a stepback and question could help.

Thanks in advance,

Shai

Hi Wade, thanks a ton for your work on Zend AMF! I was wondering if you can point me towards how I would send responses of binary data. Using the native PHP strings I can send binary data just fine, and can see that it is being sent correctly over the wire. However, when it’s received by my Flex app, it becomes truncated at the first null character (!) and the rest is lost. I guess that I need to send it on the wire as a ByteArray type… but I can’t figure out how to make Zend AMF do this. Could you give me a clue how to proceed?

Some interesting tests on transfering data in flex indicated to me that AMF may not be the fastest way.

http://www.remwebdevelopment.com/dev/a39/Flex-The-Fastest-Way-to-Transfer-Data.html

I don’t care what anyone else says about you. You are doing great work with Zend AMF. If we cross paths I will buy you a drink. Seriously, heroes work you are doing, because without this I would not be using/coding/or even looking at Flex.

Need some help!!!

Hi
Thanks and appreciate.
Anyone know how I can set object relational mapping with flex and zend amf such as one-many relationship ?

Looking forward to hearing from you

Hi,

Does Zend_Amf support Actionscript 2 i.e AMF0 and not AMF3?

Thanks,

Luke.

Wade,

I’m hoping I will get a chance to meet you @ Max 09′.

I was thinking about using IExternalizable to map an ArrayCollection to Array when going from Flex->PHP and from an Array back to an ArrayCollection when coming back from PHP->Flex.

This would give me all the benefits of the ArrayCollection on the client side without unnecessary complications added on the server side.

First, what are your thoughts about this idea? Do you see any red flags or problems that could be introduced by this? Second, is it even possible?

Thanks for your insight,
Beau N. Brewer

Will ZendAMF ever return to a stand alone product like it was in version 1.7.8 and below? All the other newer versions have a “require_once ‘Zend/Auth.php’;” that returns an error because Auth.php is not in the ZendAMF package. Is this a Zend sale Strategy to force people to install their entire Zend Framework? Please be clear so people can decide to continue using ZendAMF or to change to other products.

Will you be able to respond to the slow serialization issue anytime soon? At the time we’re having to completely abandon ZendAMF on developing projects, and return to AMFPHP on some completed ones. Thanks for everything Wade.

Hello, on second look that “thanks for everything Wade” might sound rude, or sarcastic on the end of the previous sentence, but that was not the intention = [ I really do appreciate all of the hard work you’ve put into ZendAMF, I like the direction it’s taken. I especially like how “services” aren’t required to be in any particular place as they are in AMFPHP. Cheers

Hi Wade.

Hi, all the examples I’ve seen for Zend_Amf/Flex, are extremely simple (for brevity, I guess). What if my service class has dependencies? How can I pass those dependencies to my service class? Is there something in the Zend_Amf module that will help me do this?

Hi Wade,

Any update on the integration of Zend_AMF and AMFEXT?

Thanks

Wade- I totally appreciate all that you have done in the way of education with regards to Zend Framework and AMF. I’ve posted my full delema here.

http://forums.zend.com/viewtopic.php?f=59&t=4629

I’m sorry to possibly take users away to the Zend Site, as I know you are looking for domains with a lot of traffic. However, I laid out my issue well on the Zend Forums. The issue I have is with the simple “Hello Wade” sample with Zend Studio 7x and the Flash Builder 4 (beta 2 plugin). This uses Flex SDK 3.4 or 4.0. Your thoughts on this would be a tremendous help. – Best, Doogle

Hi,
when I create sample code with gumbo from a database, value Objects and data typing is managed automaticly.

I have tried to create the Services now from my own PHP Classes.
Works fine except Datatyping.
Lets say a PHP function returns an array, how do I map those to a ValueObject, how do I data type it.( The sample code also returns an array.)

A tutorial HOW this all exactly works together would make customisation a lot easier.

Help Please
Cheers dl

I have a Flex frontend connecting via RemoteObject to Zend Amf. This is my only means to transport data between client layer (Flex) and the application and persistence layers (LAMP with Zend Framework).
Some ways I can address security are as follows:

1. I can address TLS by using mx.messaging.channels.SecureAMFChannel in my services-config.xml file and ensuring Flash player is loaded into a HTTPS wrapper and is in fact using HTTPS since the AMF protocol is layered on top of HTTP
2. RemoteObject has a setCredentials method with which I can pass AMF authentication headers to protect user related data. Assuming TLS was actually secure I can expose methods on the endpoint after authenticating the User.
3. I can protect against cross-site scripting and other FLASH vulnerabilities with a properly set up crossdomain.xml

The question I have is how to I protect my endpoint against another AMF consumer? For instance, if there were another AMF consumer (not Flash so not bound by crossdomain.xml and Flash sandbox security) other than my Flex client that knew my endpoint, what would stop it from using methods that the endpoint exposes?

As far as I know I essentially need a way to authenticate my Flex application against my Zend Amf endpoint. After AMF consumer authentication, I have some of the security mechanisms I mentioned above to protect certain pieces of data (like User authentication). I can not embed some sort of authentication mechanism into my Flex swf because the swf is vulnerable to decompilation (the swf can not be trusted). While sensitive data is protected via User authentication the unprotected data is hardly public but as far as I can tell is totally open for public consumption.

hello,
I have an error with zend AMf, I’m working with zend 1.9.7 and flex 3.2.0

Hi,

I have spent hours searching for an answer to this one and was hoping you might be able to assist!

I am trying to pass a parameter via a NetConnection object in AS3 (Flash CS4), viz: ncDB.connect(serverName, param) and then have the parameter picked up by my class on the Zend Amf server side, ie,

$server = new Zend_Amf_Server();
$server->setClass(“className”,”",param);

class className {
public function __construct($param) {
mysql_connect(“localhost”,”$param”,”passwd”);
mysql_select_db(“$param”);
}

I can successfully connect to the server when all references to the param are removed and are replaced by a hard coded name.

Any suggestions gratefully received!

Thanks in anticipation.

Hi, i’m also having troubles using Zend_Amf with Flex. I set everything up according to the tutorial on
http://framework.zend.com/wiki/display/ZFPROP/Zend_Amf+-+Wade+Arnold but I always get a an error (in Flex) with the following message:
Channel.Connect.Failed error NetConnection.Call.BadVersion: : url: ‘http://localhost/flexshop/’
(The directory flexshop is where the index.php with the amf server is located).
In my index.php I do the following:
[CODE]
require_once ‘Zend/Amf/Server.php’;
require_once ‘Flexshop/HelloWorld.php’;

$server = new Zend_Amf_Server();
$server->setClass(‘HelloWorld’);

echo $server->handle(); //OR: $server->handle();
[/CODE]

If I simply use $server->handle(); without the “echo” in the last line, the Flex application does not get an answer from the service and keeps waiting forever. If I use “echo” it gets an answer which results in the error message already stated. Pointing to the service with a browser opens a file download dialogue which offers me a file of the type “application/x-amf” – what seems basically correct. However, this file contains just a string: Zend Amf Endpoint.

1. I’m not sure what the file returned SHOULD contain. Maybe at least this part of the app is correct and the error is on the Flex-Side.
2. Has anybody any idea what goes wrong here? In fact, I tried different tutorials and different settings but had no success in getting Zend_AMF to comuciate correctly with Flex. Maybe I do have a more general configuration somewhere (something in the apache or php config?) that I do not know is relevant to Zend_Amf. I have no clue where to look, any hint would greately be appreciated.

Anyway, I guess if I could get Zand_Amf to work, it would be a great tool. (I’ve read a lot about it while searching for a solution…)

Greets,

Michael H.

Okay, I finally solved my BadVersion error. The lesson is: Watch out for spaces that should not be there (in AMF’s opinion) and that COULD appear at the beginning or end of your PHP files. In my case, the HelloWorld class had a few spaces at the end after PHP’s closing tag. After I removed them, everything worked as it should.
By the way, Zend_Amf seems to be supposed to return a file download dialogue, offering a file which contains the line “Zend Amf Endpoint” But there should be no spaces at the beginning or end of the line. (Before I fixed my mistakes, there were some spaces at the beginning of the line in this file).
There is also a nice tool for debugging Zend_Amf Applications, called “Zamf Browser”:
http://www.zamfbrowser.org/

Ok, now I’m going to enjoy my working Zend / PHP connection… Thanks for this tool!

Hi,
I’m developing a flash cms using Flex + PHP (Zend Framework – Zend_AMF)…
I switch between my zend_amf gateway and amfphp gateway and the result was a performance improvement about 2x faster, without amfext…

So, i would like to know if theres a coming release of zend_amf more eficient and with amfext suport

bruno and philou if you used zend mvc try in flash

[code]connection.objectEncoding = ObjectEncoding.AMF3;[/code]

and in php

[code]Zend_Layout::getMvcInstance()->disableLayout();[/code]

and use a blank view

Hi,
I’ve a problem regarding credentials authentication with the latest svn sources.
If I add the following line to my pure as3 project, php drops a notice level error message:

PHP Log =>

I have no success to get the \Zend\Amf\Adobe\Auth class working. Anonymous user access works but i cannot authenticate other users, both from client or server side.

Also i’m wondering that are there any open source library that simulates the Flex like Messaging framework, so i could send CommandMessages to the server with a pure as3 client?
