Pawel Graczyk	Friday 13 March 2009 1:20:49 pm Is it possible to create an image alias automatically, in time when image is being uploaded? I'm making ajax gallery. I would like to use ajax to call for image url, problem is, I cannot use attribute_view_gui() or any other template function/operator to generate my foto.

Sunday 15 March 2009 5:21:12 am It can also generate xml if you want to (if you use soap or xslt), and there are some more advance stuff in the ezcore extension if you need more ajax features( see http://projects.ez.no/ezcore ). eZ Online Editor 5: http://projects.ez.no/ezoe \|\| eZJSCore (Ajax): http://projects.ez.no/ezjscore \|\| eZ Publish EE http://ez.no/eZPublish/eZ-Publish-Enterprise-Subscription @: http://twitter.com/andrerom
Patrick Kaiser	Tuesday 05 May 2009 1:28:56 am Just in case someone has also problems to use this code: Make sure you add the ContentClass which has the image attribute you want use to the AvailableImageDataTypes[] under block [ImageDataTypeSettings] settings in site.ini: [ImageDataTypeSettings] AvailableImageDataTypes[]=yourCustomClassWithImageAttribute Then the requested ImageAlias will be created on the first request. Try this in your module: $ezAjaxOptions = array( 'dataMap' => array('all'), 'fetchPath' => false, 'fetchChildrenCount' => false, 'dataMapType' => array(), 'loadImages' => true, 'imagePreGenerateSizes' => array('yourCustomImageAlias') ); $node = eZContentObjectTreeNode::fetch( $testNodeId ); $node_reduced = eZAjaxContent::simplify( $node, $ezAjaxOptions ); Best regards, Patrick
