AJAX to return an eZ Publish template? eg new comment

Hi Paul

The ezxajax_classattributes extension uses the result of some templates: http://projects.ez.no/ezxajax_classattributes

You may use your custom library (e.g. if you would like to you scriptacoulus, extjs or jQuery) and access your custom eZPublish templates via the "layout/set" functionnality.

So, you design your own functionnality in a custom module, like fetching meteo on yahoo.com, and to call it, you may use this one to change the layout :

http://www.mydomain.com/mysiteacess/layout/set/ajax/mymodule/myfunction/parameters..

All you have to do is to declare a new pagelayout template for ajax (pagelayout_ajaxa.tpl), set up your layout.ini file and finally edit the pagelayout file as :

{$module_result.content}

Or maybe there's something eZier but I haven't found.

Hi Patrick,

Here's a cut-down version of where I got to. I did get it to work. Please note that for simplicity I have stripped out some of the logic in this code (some elements to check permissions), so there may be some extra pieces here that can be safely removed / ignored. Some of the include statements are in peculiar places through the code for similar reasons. I'm heading away for a few days, so apologies for the rushed code & reply.

function EditBox($ContentObjID){
	// Add Includes required for function, others loaded IFF logic shows they're needed.
	include_once( 'kernel/classes/ezcontentobject.php' );

            $Result = array();
            $Result['content'] = $tpl->fetch( 'design:content/edit.tpl' );

	// Create New Object Response
	$objResponse = new xajaxResponse();
	$returnthismessage=$Result['content'];
	$objResponse->setReturnValue($returnthismessage);

    // Send Response
	return $objResponse;

@Maxime
Just a small hint: You should always write own modules for such kind of functionality.
This is much faster than using the /layout/set functionality. Especially for AJAX.
Within you module you can just fetch the content you need and output it directly without using the template engine. (For example as an xml document)

Mit freundlichen Grüßen
Best regards

Ajax views should have something like this in it's end:

eZDB::checkTransactionCounter();
eZExecution::cleanExit();

1. Avoids possessing of pagelayout
2. stops the execution, so the sessions variables for remembering last accessed page is not stored for this ajax url.
