Trouble with ezimagealiashandler

Monday 03 October 2005 1:11:43 am

Hi,

If your purple.jpeg is taken from a camera, the guilty might be crap data on EXIF. ez stores the EXIF data on xml. It tooks me an howfull lot of time to find this one ;)

I've modified the ezimage libs so they don't store any information about EXIF, that is never used anyway if I'm right (there is a bug report about that filled by someone else).

Use this code to get image URL

$objectWithIMG = eZContentObject::fetch( 171 );

$dataMap =& $objectWithIMG->attribute( 'data_map' );

$image =& $dataMap['image']->content();

$list =& $image->aliasList();

var_dump( $list['original']['url'] );

This seems to work (for the most part) but some weird things happen :

1) I can't doeZDebug::writeNotice($imageattribute->content()), that gives (that is probably because some circular reference I'd say):

class ezimagealiashandler { var $ContentObjectAttribute = class ezcontentobjectattribute { var $HTTPValue = NULL; var $Content = class ezimagealiashandler { var $ContentObjectAttribute = class ezcontentobjectattribute { var $HTTPValue = NULL; var $Content = class ezimagealiashandler { var $ContentObjectAttribute = class ezcontentobjectattribute { var $HTTPValue = NULL; var $Content = class ezimagealiashandler { var $ContentObjectAttribute = class ezcontentobjectattribute {
Fatal error: Nesting level too deep - recursive dependency? in /home/buz/www/Exponential-3.7.0rc2/lib/ezutils/classes/ezdebug.php on line 569

2) Not all available aliases are being shown, it seems:

This is more worrisome. While there are three aliases defined, I only get to see one plus the original one?
