Help with PHP Connector
Hi Everyone
I think I'm causing myself a problem with the Wookie PHP connector and
wonder if any of you can help me.
The demo site <address>:8080/wookie/ works fine but when I instantiate my
own widgets the browser throws up an error, even though the widgets then
seem to function as intended. I get the same symptoms using Firefox,
Chrome, Opera and Internet Explorer. I'm running Wookie 0.11 on my test
server (Windows XP) and also Wookie 0.13 locally from a USB drive for
development (Windows 7). Both are using the internal database. I get the
same issue on both platforms and so the common factor seems to be my PHP
scripting.
When I load a widget instance (instantiated through the PHP connector)
using the URL provided by the connector, for example...
http://127.0.0.1:8080/wookie/deploy/wookie.apache.org/widgets/simplechat/index.htm?idkey=0qfFcvflywg5wYVQUcRorsUA2mU.eq.&proxy=http://127.0.0.1:8080/wookie/proxy&st=
...the following dialogue box appears (everything done in Firefox for this
email)...
"The page at 127.0.0.1:8080 says: Error".
In the Developer console I see two error lines.
1) Stack trace from engine.js, function dwr.engine._debug, line 1310.
[09:18:51.198] http://127.0.0.1:8080/wookie/dwr/engine.js ::

2) Error: undefined, Error
[09:18:51.199] Error: undefined, Error
Here are the Wookie related sections from my PHP.
require '../connector/wookie/WookieConnectorService.php';
$admin1 = "Waldorf";
$user1 = "Animal";
$widgetidentifier = "http://wookie.apache.org/widgets/simplechat";
// Create shared data key for connector
$sharedDataKey = date('Ymd') . stringrandom(8);
// Initialise Wookie Connector
$widgetconnector = new WookieConnectorService("http://localhost:8080/wookie",
"TEST", $sharedDataKey, $admin1, $admin1);
// Create new instance of specified widget
$widgetconnector->setUser($user1);
$widgetinstance1 = $widgetconnector->getOrCreateInstance($widgetidentifier);
// Show instance details
var_dump($widgetinstance1);
// Create iframe to display widget
echo "<iframe src='" . $widgetinstance1->getUrl() . "' height='" .
$widgetinstance1->getHeight() . "' width='" . $widgetinstance1->getWidth()
. "'></iframe>";
Here's an example of the var_dump output...
object(WidgetInstance)#8 (5) { ["url":"WidgetInstance":private]=>
string(171) "
http://127.0.0.1:8080/wookie/deploy/wookie.apache.org/widgets/simplechat/index.htm?idkey=cHOKJcOG.pl.0XvYda.pl.ichxQFvlfsQ.eq.&proxy=http://127.0.0.1:8080/wookie/proxy&st="
["guid":"WidgetInstance":private]=> string(43) "
http://wookie.apache.org/widgets/simplechat"
["title":"WidgetInstance":private]=> string(10) "SimpleChat"
["height":"WidgetInstance":private]=> int(383)
["width":"WidgetInstance":private]=> int(255) }
My full test PHP script instantiates four widgets, for four different
users, using the same shared data key. I receive the same error for each
instance, but interwidget communication works properly and the correct user
is associated with each instance.
I've no idea where to take things from here and would really appreciate any
help you can offer.
Thanks
Tim.

Hi Paul
That worked a treat and the error has gone. Thanks ever so much for that,
I owe you a drink next time you're in.
Using the new version of WookieConnectorService.php, PHP did show the
following...
Notice: Undefined variable: request in
F:\xampp\htdocs\sponge\connector\wookie\WookieConnectorService.php on line
196
Line 196 is...
$request.= '&api_key='.$this->getConnection()->getApiKey();
... and $request didn't look like it had been defined earlier. I changed
the assignment operator on $request from .= to = and this removed the
notice. However I don't know if I'm impacting on anything else by doing
this (I think David Sherlock sorted this for me in an earlier version of
the connector). It seems fine but I thought you might want to know.
Thanks ever so much again for your help.
Best wishes
Tim.

Just to add that this fix is can be found in the
WookieConnectorService.php file.

Hi Tim,
I think this might be due to a bug in the connector which I have just
fixed and committed. Looks like the wave feature needed an extra attribute.
If you get the update from svn, retry to see if everything works (note:
You'll have to make sure you are creating new instances - so use another
key)
