1) select
$sql=" SELECT *, concat(foto_dir, '/', foto, '|', breedte, '|', hoogte) as beeld, foto_id as exif FROM ".$_SESSION[ '_fotos_' ];
2) link-field
Column-declaration
"exif" =>array("header"=>"EXIF", "type"=>"link",
"align"=>"left", "width"=>"", "wrap"=>"nowrap", "text_length"=>"-1",
"tooltip"=>"false", "tooltip_type"=>"floating|simple", "case"=>"normal", "summarize"=>"false",
"sort_type"=>"string", "sort_by"=>"", "visible"=>"true",
"on_js_event"=>"", "field_key"=>"exif",
"field_data"=>"foto_id", "rel"=>"", "title"=>"", "target"=>"_self",
"href"=>"javascript:openeenw({0},'_show_exif.php', 500,400)"),
Note foto_id is field in the used table
2) Javascript:
function openeenw(fo, bestand, br, ho)
{
spec = "resizable=1, width=" + br + ", height=" + ho;
br = br - 40;
ho = ho - 40;
window.open("<? echo $_SESSION[$_SESSION['pregrp']]['subdir']; ?>include_beheer/" + bestand + "?b=" + fo + "&br=" + br + "&ho=" + ho,"mywindow", spec);
}
3) Now I run the php

I put a red frame around the concerned link-field. It also show's the data that should be returned to the javascript.
fields with this data are foto_id or exif
The returned value however is 10229
When I run, I do not get an error !!!
Debugger is on, and no errors are showed
But, When I see the opened window, the firsth parameter isn't the foto_id.
Thus, the call is running, but the field_data isn't passed and I got a wrong one
//localhost/image_data/albumbeheer/include_beheer/_show_exif.php?b=10229&br=460&ho=360
Here a pciture

No where in the table is a field with this content.
What could be wrong ?
