Created Issue: Exceptions not passed properly to debug framework

hpatcouto — Mon, 08 Sep 2008 16:32:44 GMT

Most of what's needed to pass PHP exceptions right through to JavaScript is there, except for an HTTP header that the framework checks. Add

header('jsonerror:true');

at line 95 to enable it.

Now you can see your exception message rather than "The 'd' property is missing from the JSON wrapper" (emitted by the Debug library).

Created Issue: Useless $applicationRoot

hpatcouto — Mon, 08 Sep 2008 16:26:20 GMT

MSAjaxProxyGenerator defines $applicationRoot at line 12. It is never used and is useless.

cwenz — Sat, 30 Aug 2008 10:44:56 GMT

A small set of PHP files to support using the Microsoft AJAX Library with PHP web applications. The current release supports creating web service proxies in PHP code such that the Microsoft AJAX Library (a free download from http://ajax.asp.net) can call them from client-side code. Future releases will support localization and globalization, debug and release scripts, and more features inspired by ASP.NET AJAX.

Download

Download the current release: 4 Alpha

Requirements

A web server -- Steve and Christian have personally tested on IIS7 (Vista) and Apache (Ubuntu 6.06, with PHP5.2 from 'feisty')
PHP 5.2+ -- 5.2+ is required for json_encode/json_decode; on older versions you can manually install php-json
Version 3.5 of the Microsoft AJAX Library (older versions are supported by 3 Alpha)

Installation

Download the current release and unpack it locally.
Download the Microsoft AJAX Library from http://ajax.asp.net/.
From your PHP code, include MSAjaxService.php from your service code.
From your client code, include MicrosoftAjax.js via a script tag. (This file is part of the Microsoft AJAX Library you downloaded in step 2.)

NOTE: The samples included in the full distribution will not work until you download the Microsoft AJAX Library. See the readme.txt in the MicrosoftAjaxLibrary directory where you unpacked PHP for Microsoft AJAX Library.

Hello World Example

A basic example showing how to expose a web service from PHP and consume it from the browser. This sample can be found under samples/HelloWorld in the source distribution.

HelloService.php:

<?php
 
require_once '../../dist/MSAjaxService.php';
 
class HelloService extends MSAjaxService
{
    function SayHello($name)
    {
        return 'Hello, ' . $name . '!';
    }
}
 
$h = new HelloService();
$h->ProcessRequest();
 
?>

index.html:

<html>
<head>
<title>Hello, World!</title>
<script type="text/javascript" src="../../MicrosoftAjaxLibrary/MicrosoftAjax.js"></script>
<script type="text/javascript" src="HelloService.php/js"></script>
</head>
<body>
Name: <input id="name" type="text" /> <input type="button" value="Say Hello" onclick="button_click(); return false;" />
<br />
Response from server: <span id="response"></span>
</body>
<script type="text/javascript">
    function button_click() {
        HelloService.SayHello($get('name').value, function (result) { $get('response').innerHTML = result; });
    }
</script>
</html>

Microsoft AJAX Library 3.5 is now supported; older versions are not supported (use version 3 Alpha instead).

Patch Uploaded

dherbst — Mon, 07 Jan 2008 13:27:59 GMT

dherbst has uploaded a patch.

Description:
This patches MSAjaxService.php when using MicrosoftAjaxLibrary 3.5. There seems to have been a breaking change from the earlier msajaxlibrary which did not put the result data into the "d" property of the returned json object.

The fix is line 87 to add the array wrapper:

echo json_encode( array("d"=>$returnValue));

This should fix iss #4997 for you.

Please let me know if you have any questions.

COMMENTED ISSUE: b has no properties

Dzonny — Sun, 06 Jan 2008 13:47:30 GMT

Trying your hello example creates "b has no properties" error in MicrosoftAjax.js line 5.
When changing script source from MicrosoftAjax.js to MicrosoftAjax.debug.js is says:
Chyba: [Exception... "'Sys.Net.WebServiceFailedException: Sys.Net.WebServiceFailedException: The server method 'SayHello' returned invalid data. The 'd' property is missing from the JSON wrapper.' when calling method: [nsIOnReadyStateChangeHandler::handleEvent]" nsresult: "0x8057001c (NS_ERROR_XPC_JS_THREW_JS_OBJECT)" location: "<unknown>" data: no]

Using PHP PHP 5.2.5, Apache 2.2.6, Windows XP Pro, FireFox 2.0.0.11

And getting undefined also in IE

.... and exception when using MicrosoftAjax.debug.js:

COMMENTED ISSUE: b has no properties

Dzonny — Sun, 06 Jan 2008 12:19:40 GMT

There was a problem with your PHP code and my very strict PHP settings. It generated a notice:
 
Notice: Undefined index: HTTP_CONTENT_TYPE in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\filestore\phpmsajax\MSAjaxService.php on line 60 
So, I've altered the line 60 from
if ((strpos($_SERVER['HTTP_CONTENT_TYPE'], 'application/json') !== 0) && (strpos($_SERVER['CONTENT_TYPE'], 'application/json') !== 0))
to
if ((strpos(@$_SERVER['HTTP_CONTENT_TYPE'], 'application/json') !== 0) && (strpos(@$_SERVER['CONTENT_TYPE'], 'application/json') !== 0))

now I¨m getting undefined instead fo hello message :-(

COMMENTED ISSUE: $_SERVER variable HTTP_CONTENT_TYPE doesn't exist -- Still an Issue

bencornwell — Mon, 25 Jun 2007 13:40:08 GMT

Here is the correct way to solve it: if ((isset($_SERVER['HTTP_CONTENT_TYPE']) && strpos($_SERVER['HTTP_CONTENT_TYPE'], 'application/json') !== 0) || (isset($_SERVER['CONTENT_TYPE']) && strpos($_SERVER['CONTENT_TYPE'], 'application/json') !== 0)) { header('HTTP/1.0 500 Internal Server Error'); throw new Exception('Wrong content-type, should be application/json'); } Comments: ** Comment from web user: bencornwell **

actually - that should be

if( array_key_exists( 'CONTENT_TYPE', $_SERVER ) ) { //do something }

Standard argument ordering isn't one of PHP's strong points ;)

COMMENTED ISSUE: $_SERVER variable HTTP_CONTENT_TYPE doesn't exist -- Still an Issue

bencornwell — Mon, 25 Jun 2007 13:33:28 GMT

Hi Steve - just caught your presentation at ReMIX07 and thought I'd check out the phpmsajax project.

I hit the issue described above - it's actually a PHP5 -> PHP4 legacy issue. PHP5 (strict mode) will generate an error if the array index you're trying to access doesn't exist, while PHP4 (or PHP5 running a more forgiving error_reporting() setting) won't.

Further, the isset() probably isn't the best way to test this condition either - the best way I've come across is: if( array_key_exists( $_SERVER, 'CONTENT_TYPE') ) { //do something }

Happy to submit a patch - just let me know how :)

CREATED ISSUE: solution of how to cast to an arbitrary class

heygrady — Wed, 25 Apr 2007 21:33:27 GMT

PHP maintains a generic empty class stdClass from which all class are built in PHP. You can use that class to create generic class objects anytime you wish.


$class = new stdClass();
$class->randomProperty1 = 'foo';
$class->randomProperty2 = 'bar';

Aditionally, PHP5 supports object cloning. http://us2.php.net/manual/en/language.oop5.cloning.php
