replace IPTC Title with IPTC Copyright
clemphoto:
Developing a new photo viewing site, http://clemsonphotos.org/coppermine is the gallery location. Using 1.5 RC, and every thing seems to work. But, for my application, I would prefer to have thumbnails and files displayed with something other than the image title below the image. Due to the nature of the project, the IPTC Copyright field would be more appropriate. I don't see how this can be done without modifying code, and what and how to modify are not clear. Is this something that can be done by a user, or should it more properly be viewed as a feature request?

Your subject is wrong: you don't replace the IPTC title, but the regular thumbnail title, because that's what actually shows as far as I can see.

That's not a feature request, but clearly a matter of custom theme modification, so I'm moving this thread accordingly. A feature request is a request for a feature in a future coppermine release. Your request clearly won't go into a future version; you want a solution now and not in the distant future.

It's actually cpg1.5.3 RC - that's the official version number.

This is a request that is very similar to your other thread replace Title with Copyright. All you need to do is take a look at Documentation -> Creating your custom theme ff.
In the first place you need to do as suggested in Rename your theme first. Next, I want you to read Editing theme.php, because that's what we need to do.We'll need to edit the function definition for theme_display_thumbnails, so you'll have to copy that section from the sample theme first into your custom theme, i.e. you copy from themes/sample/theme.php

and paste that into a new line before
--- Code: ---?>
--- End code ---
into the file themes/yourtheme/theme.php
Finally you need to populate the title accordingly: find
--- Code: --- $wrapper_start = CPGPluginAPI::filter('theme_thumbnails_wrapper_start');
--- End code ---
in the code you just added and add before that into a new line something like
--- Code: --- if ($iptc['Copyright'] != '') {
$title = $iptc['Copyright'];
}
--- End code ---
We're not done yet - the variable we pasted in doesn't reside inside the scope of the function that we're modifying. So, find
--- Code: --- global $CONFIG, $CURRENT_ALBUM_DATA;
global $template_thumb_view_title_row,$template_fav_thumb_view_title_row, $lang_thumb_view, $lang_common, $template_tab_display, $template_thumbnail_view, $lang_album_list, $lang_errors;
--- End code ---
in the code you inserted and add underneath it (into a new line of it's own)
--- Code: --- global $iptc;
--- End code ---
Please report back if this works as expected, as I haven't actually tried my suggestions, but coded it from the back of my head.
I'd really like to see you try a little harder before you ask a question: please give the documentation a try.
clemphoto:
My thinking was that the thumbnail title contains the IPTC Title, and I would prefer it to contain the IPTC Copyright. Perhaps I need to write in a more detailed and explicit way. I noted in a reply on another thread the challenge of knowing where to look to effect a change. That is another challenge in my newness to this. I assure you, I have read the documentation, to less good effect that I would have wished for the issues I need to resolve.
I will try this, and then expand the scope of my modifications to see how to do the same thing in display of pictures. I will post here and let you know of my progress, and of course when the issue is resolved.

Nibbler:
If you simply want to import the IPTC Copyright instead of the IPTC Title, just change picmgmt.inc.php from
--- Code: ---$title = (isset($iptc['Title'])) ? $iptc['Title'] : $title;
--- End code ---
to
--- Code: ---$title = (isset($iptc['Copyright'])) ? $iptc['Copyright'] : $title;
--- End code ---
Then re-add your pictures.
clemphoto:
Considering future software updates, is it better practice to do this in a custom theme, rather than modify picmgt.inc.php?
