Summary0000174: use_exif_mapping is not taken into account during metadata synchronisation to update database
Descriptionuse_exif_mapping may describe other field than date_creation when using an extended config_local.inc.php
$conf['use_exif_mapping'] = array(
  'date_creation' => 'DateTimeOriginal',
  'author' => 'Artist',
  'comment' => 'ImageDescription'

In that case, we would like to have these fields updated as for IPTC in the update_metadata() function.
this code: $update_fields = array_merge($update_fields,
is also good for EXIF.

A problem may occur when both EXIF and IPTC are used. Need a way to choose one or the other in the config file ?
Additional InformationThanks a lot to all the team for its very good work!

Waiting for RC2....

I've just updated the "Product version". My current filter is on release 1.5.0RC1 so I didn't see your bug entry. I'll look at it tomorrow in depth.

Thanks for your accurate analysis.

Here I read two issues :

1. bug: in admin/include/functions_metadata.inc::update_metadata function, only date_creation is added to $update_fields even if other keys are configured in $conf['use_exif_mapping']. The correction is as you say, copied from IPTC.

2. feature request: by default IPTC values overload EXIF values for a single key (date_creation for example). You ask a configuration parameter to choose EXIF more important than IPTC.

Concerning the bug correction, I've made the correction and it works fine.

Concerning the feature request, I refuse it. Indeed, I think you should not have keys in common among EXIF and IPTC. If you really want that, you'll have to modify (easy for you I think) the order of EXIF and IPTC retrieval in the foreach loop.

Do you agree with this? (OK means I close the bug entry)

Thank you for such a quick answer and reactivity!
The most important for me is the bug correction to avoid a code modification in each new version. Thanks for that.
Regarding point 2, as you said, I dont use IPTC at all, then it is not a problem for me to have the code left as it is now (IPCT priority over EXIF when both exist). I suppose also that most people wont use both at the same time with the same fields... hope so ;)

Fine :-) I've just commited the bug correction in CVS.
