Extension with Zend AMF Server

Tuesday 14 April 2009 7:56:11 am

Hello,

I've been working on an extension for Ez Publish that allows me to let Flex communicate with Ez Publish. I've got it working, after some struggles, using Ez Publish 4.1 and Zend AMF Server.

But in order to get responses back from Ez Publish I've had to change the index.php file where at the very end where the echo happens of the output ($out) the php function "trim" is used to get rid of any whitespaces around the output.
Apparently, this trim function removes a vital character for the response of the Zend AMF Server as I only had to remove this trim call in order to get the communication working properly.

Can this be regarded as an issue? :) I wonder why that trim is even there as browsers should have no problem with a little whitespacing around the output. But it obviously poses a problem for using Zend AMF Server with Ez Publish.
Itsnot cool to have to change any files from Ez Publish itself with each update / reinstall.

Regards

You should create an issue for this.
But not sure we can just remove it, it's there for a reason.

Doesn't 'some' browsers fall back to quirks mode if there is anything before doctype tag in html?

that's true but IMHO if you have such a problem you should fix your templates. You can imagine cases where you want to output some spaces at the beginning or the end of the output.
It seems that this "feature" was added in revision 19872 but the commit log doesn't help a lot.

$ svn -v log -r 19872 index.php

Sweet, adding that to the extension allows me to leave index.php untouched. Thanks for that :)

Indeed pagelayout is disabled as I dont want any other output but that from the Zend AMF Server.

This shows one thing I find problematic when developing on Ez Publish though, where could I have found out, in documentation, how to properly exit the extension view?
It seems stuff like this you need to run into, then ask a question and thus the answer appears.
I've seen the articles (and thus knew how to create an extension), the api (which has very little useful info), the technical documentation, which is decent.

Am I missing an important source of information somewhere?

Hi

I have developped an extension to communicate with AMF (Zend_AMF) and I'm about to release it on projects.ez.no. It's called <b>jvAMF</b>

It's quite simple an do not need kernel hack. As far as I know, Flash Player ignores everything that's after the AMF content. It works well with the debug on, but fails with template debug (with the inline comments).

Next step is to develop a service debugger for the admin, which can be quite tough...

Hi Gaetano

I didn't know about this extension <i>ezdebug</i>, I'll check, thanks.
I've looked at your extension, nice :-). What I would like to do is to try to implement the AMF service debugger from AMFPHP with Zend AMF

There exists an older (2007/php5/ez4) example extension which provided amfphp which can be used with eZ Publish via php to provide data to flash using the AMF protocol.

<i>http://projects.ez.no/remoting
http://svn.projects.ez.no/remoting/trunk/extension/remoting/

It even comes with the initial examples and detailed installation instructions.

Cheers,
Heath
