popup title shows ‘title’, but it should show ‘caption’

Not sure what you mean when you say “it should show”. The plugin is meant to show a title on mouse-over, and that is what it shows. Are you asking for a feature to be able to show the caption on mouse-over?

but in a regular wp gallery the title is nothing but the name of the pic minus the extension.

In a regular WP gallery, the title and caption are both editable fields. If you look at the standard WP “Add media” behavior, the title (never the caption) is used to populate the “title” attribute on links, which shows up when you hover over an image, or, in devices for the blind, shows up in the “alt” attribute. This behavior is consistent between Photonic and WP. In fact, in WP the caption only kicks in if the caption field is populated (which triggers the caption shortcode), and even then the title is what is used for the link title and image alt. In every scenarios WP uses the title, and it only uses the caption when present, that too in a limited manner.

Problem is, most users will add a meaningful description to the image in the “caption” field, which corresponds to post_excerpt, leaving the title field alone, because this is pre-filled by WP.

That is debatable. For every user you show me that uses captions and not the title, I can show you a user that ignores the caption altogether in favour of the title, and I can show you another user that uses both.

But, back to my original question: are you looking for help in displaying a caption? Can you help me with answers to the following?

1. What type of provider – Flickr, Smugmug, Zenfolio, 500px, Picasa, or Instagram?
2. What type of layout – embedded in a page or in a lightbox? Note that for the cases where the shortcode supports single-image display, the caption is already shown. See http://aquoid.com/news/plugins/photonic/flickr/flickr-photo/, or http://aquoid.com/news/plugins/photonic/zenfolio/photos/, or “Enjoying the sunshine” here: http://aquoid.com/news/plugins/photonic/500px/. Also, in case the title is empty, for each of the providers the caption is displayed in the lightbox or on mouse-over.
3. Which lightbox – Swipebox, PrettyPhoto, Colorbox or Fancybox?

Are you using a child theme / custom theme? If so, are you familiar with the use of filters?

I am adding this to the plugin, in the file photonic.php, after line 654, and line 679:

$title = apply_filters('photonic_modify_title', $title, $attachment);

If you have a child / custom theme, you can perform these steps:

1. Make a call to add_filter in your child / custom theme’s functions.php, and add a filter for photonic_modify_title this way:
   add_filter('photonic_modify_title', 'my_theme_photonic_modify_title', 10, 2);
2. Then, create a function my_theme_photonic_modify_title this way:

   function my_theme_photonic_modify_title($title, $attachment) {
   	return empty($attachment->post_excerpt) ? $title : wptexturize($attachment->post_excerpt);
   }
   

Since I will be adding the filter hook photonic_modify_title to the plugin code, your edits will be upgrade-safe if you follow the above approach.

If you are not using a child / custom theme, you can modify the plugin directly by changing line 650 and line 675:

$title = wptexturize($attachment->post_excerpt);

This change is not upgrade-safe, so everytime the plugin is upgraded you will have to redo the change.

Looks like an oversight at my end, which I will fix for the next version.

This is the code:

1. Right after you added the title code in line 680, put in this code:

   
   $shown_title = '';
   if (in_array($photonic_wp_thumbnail_title_display, array('below', 'hover-slideup-show', 'hover-slidedown-show')) && $title != '') {
   	$shown_title = '<div class="photonic-title-info"><div class="photonic-photo-title photonic-title">'.wp_specialchars_decode($title, ENT_QUOTES).'</div></div>';
   }
   

2. Then, a few lines later, you have this code:

   
   $ret .= "<a href=\"".$src[0]."\" rel='$rel' title='$title' $slideshow_library_class><img src='".$src[0]."' alt='$title' /></a>";
   

   Replace it with:

   
   $ret .= "<a href=\"".$src[0]."\" rel='$rel' title='$title' $slideshow_library_class><img src='".$src[0]."' alt='$title' />$shown_title</a>";
