Once you get it to work a whole world opens up as you know “own” a good way to to databased things. Also, besides the Flex Builder, all of this software is free. My demo runs on a cheap shared commercial server, so there’s no heavy or expensive middleware to buy. Stay with it.

You need to track down why the object you are working with does not (yet) exist when you see this error:
Cannot access a property or method of a null object reference

The players.mxml file has compilation warning
Severity and Description Path Resource Location Creation Time Id
Data binding will not be able to detect assignments to “countriesXML”. Players/src Players.mxml line 285 1264001802015 71

Data binding will not be able to detect changes when using square bracket operator. For Array, please use ArrayCollection.getItemAt() instead. Players/src Players.mxml line 272 1264001802000 70

The application runs but reports httpService errors for countries.xml.

I can see the datagrid populated with the playes from the database but if I click any user to display the popup screen I then get the error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

I beleive I have all the bits in the right place and assume my running errors are a result of the compilation warning. Does there need to be a [Bindable] statement somewhere?

http://www.flos-freeware.ch/notepad2.html

// optional path include or do this within php.ini
// a final \ at the end of $inc_path results in a hidden syntax error making the path invalid.
// after solving that I found that the loader folder was missing from my ZendAMF download software
// so downloaded the full monty instead.
$inc_path =’;C:\Program Files\ZendFramework-1.9.7\library\;C:\Program Files\PostgreSQL\EnterpriseDB-ApachePhp\apache\www’;

ini_set( ‘include_path’, ini_get(‘include_path’).$inc_path);
$inc_path = ini_get(‘include_path’);
// show path
// echo $inc_path;

Now for chapter 3 the interesting bit, thanks for your time.

This whole exercise is about putting the pieces together. We know it works as the live demo does. You have all the code, so now its just lining it up in a workable manner. Since my stuff is all Linux based you want to be sure of the paths and directories, look out for “/” where you need “\”. If your base Apache works, then you got the right starting place. The zendamf.php file must then live in the Apache root.

Where you are at now is making the PHP stuff work. Turn on all error reporting. For the error you got on line 20, check that there is in fact a Players_service.php file where you said it was. Once you straighten out the paths and all the VO and SERVICE files are in place, you should see the Zend AMF Endpoint message at http://localhost:8080/zendamf.php

If we don’t see this message: Zend AMF Endpoint , then we DO NOT have a valid install and may not progress until we do.

Be sure that whatever Zend AMF version you are working with, that the library folder is within your Zend folder. We point to the directory that contains the “library” folder. Thats where all this works from.

What happens if you OMIT the :8080 from the URL?

When you do see the Zend AMF Endpoint message, go get yourself a couple of pints and some bangers!

I am running on a windows XP with PostgreSQL,PgAdmin, ApachePHP from EnterpriseDB.com and Adobe Flex3.

Working through the tutorials I have sucessfully loaded the Players database and can navigate to the default page for Apache.

I have some trouble interpreting some of the instructions because I don’t know enough yet.
In particulare how all the directories of the different parts fit together.

I have assumed that my ‘web folder’ is under C:\Program Files\PostgreSQL\EnterpriseDB-ApachePhp\apache\www
because this is where I found my default apache page when I navigated to http://localhost:8080

I also created the services and VO directories under \www with their respective php files

I have set my include path in zendamf.php to be:-

ini_set( “include_path”, ini_get(“include_path”) . “;C:\Program Files\ZendAMF-1.9.7\”);
(I did not load the full ZEN because of previous comments on 27 December)

At this point I can navigate to http://localhost:8080/zendamf.php but did not get the expected ZEN message but niether
did I get any error message. I put display_errors = on in php.ini and I now get a syntax error:-

Parse error: syntax error, unexpected T_STRING in
C:\Program Files\PostgreSQL\EnterpriseDB-ApachePhp\apache\www\zendamf.php on line 20,

line 20 is $server->setClass(“Players_service”);

The syntax must be correct so I must still have my directories and/or path wrong but I am at a loss to figure out how.

Any suggestion welcome.
Thanks

It took me a lot of work getting all these ducks lined up, but as you can see, it does work. Its worth the effort to get the PHP/Zend stable. The upside of the Zends constantly improving the Framework is also the downside, in that it changes. My demo is working with Zend AMF 1.9.2. You did the right thing making a link that you can easily update once to point to the Library of the next version. Note that you can grab the whole Zend Framework or just the AMF subsection which is all this tutorial uses. Thanks for letting people know about the link situation.
Good luck,
- Alan

I was able to get things working by downloading ZendFramework-1.9.6-minimal. After copying this to /usr/local, I created a symbolic link called ZendFramework to point to/usr/local/ZendFramework-1.9.6-minimal/library, so that I could use your code.
