[Chameleon] moving widgets into custom directories

[Paul Spencer]

Bart,

what we normally do in this case is have a configuration file that 
defines where chameleon is.

define( "CHAMELEON_PATH", "/ms4w/apps/chameleon/htdocs" );

The popups need to use CHAMELEON_PATH to access stuff like 
session.inc.php and other common code.

include( "../../config.php" );
include( CHAMELEON_PATH."/session.inc.php" );

you could make this fancier:

if (file_exists( "../../../config/config.php" ))
{
     //include application configuration file if it exists
     include( "../../../config/config.php" );
}
if (!is_defined( "CHAMELEON_PATH" ))
{
     //assume chameleon at same level as application
     define( "CHAMELEON_PATH", "../../../../chameleon/htdocs" );
}

In the widgets, you can then modify the moPopup->mszLink to be:

$this->moPopup->mszLink = 
$_SESSION['gszAppWebPath']."/widgets/myWidget/myPopup.phtml";

the popup code will only put the chameleon stuff in front of the link 
path if the path starts with ./widgets or widgets (see Popup.php 
GetPopupURL() function)

This is essentially the same solution as Bill's except that it uses the 
application web path calculated by Chameleon rather than doing it yourself.

Another solution may be to put all your widgets in a web-accessible 
location for use by all your apps ... for instance

/ms4w/apps/chameleon
/ms4w/apps/customWidgets/widgets/...
/ms4w/apps/myApp

in your CWCExecute, you would pass the path to the custom widgets directory

in your widgets, they would have a configuration file that would define 
both the CHAMELEON_PATH and CUSTOM_WIDGETS_URL

define ("CHAMELEON_PATH", "/ms4w/apps/chameleon/htdocs" );
define ("CUSTOM_WIDGETS_URL", "http://myserver/customwidgets");

$this->moPopup->mszLink = CUSTOM_WIDGETS_URL."/myWidget/myPopup.phtml";

If you use one of these solutions, can you please add something to the 
chameleon tiki so we can point others there :)
