Re: [**RESOLU**] comment faire apparaitre la légende IPTC sous la photo

I just found this thread: http://forum.phpwebgallery.net/viewtopi … 70&p=1 where I found how to get at the metadata.  Slowly, I learn! :-)
part of the metadata.php output:

Code:

no IPTC information

EXIF Fields in sample.jpg

Array
(
    [FileName] => sample.jpg
    [FileDateTime] => 1229315052
    [FileSize] => 182652
    [FileType] => 2
    [MimeType] => image/jpeg
    [SectionsFound] => ANY_TAG, IFD0, THUMBNAIL, COMMENT, EXIF, INTEROP, MAKERNOTE
    [COMPUTED] => Array
        (
            [html] => width="800" height="600"
            [Height] => 600
            [Width] => 800
            [IsColor] => 1
            [ByteOrderMotorola] => 0
            [CCDWidth] => 1mm
            [ApertureFNumber] => f/3.5
            [UserComment] => 
            [UserCommentEncoding] => UNDEFINED
            [Thumbnail.FileType] => 2
            [Thumbnail.MimeType] => image/jpeg
        )

    [Make] => Canon
    [Model] => Canon PowerShot G9
    [Orientation] => 1
    [XResolution] => 124/1
    [YResolution] => 124/1
    [ResolutionUnit] => 2
    [DateTime] => 2008:12:12 21:27:06
    [YCbCrPositioning] => 1
    [Exif_IFD_Pointer] => 184
    [THUMBNAIL] => Array
        (
            [Compression] => 6
            [XResolution] => 180/1
            [YResolution] => 180/1
            [ResolutionUnit] => 2
            [JPEGInterchangeFormat] => 3508
            [JPEGInterchangeFormatLength] => 2935
        )

    [COMMENT] => Array
        (
            [0] => Putting it back together, and trying to figure out where the two leftover screws should have gone.
        )

So, apparently it is called "comment" not caption.  Or UserComment?  Or COMMENT?  Or what?  I'm confused.  I tried "Comment" and "UserComment" instead of "Caption" in the show-exif-fields part.  No comment-related field shows up in the Synchronize window, however, so I'm not doing that right.

When I tried adding to use-exif-mapping:

Code:

$conf['use_exif_mapping'] = array(
  'date_creation' => 'DateTimeOriginal',
  'caption' => 'UserComment'                               //changed.  line added. pwg blew up
  );

The gallery blew up rather spectacularly.  (At that point the show_exif_fields did have " 'UserComment',").  So, obviously, that line is necessary for something to happen.  It just needs to be right ... :D
