That’s great! Just to clarify, when you say “linked URLs”, do you mean URLs in the “URL” bibliographic metadata field, or linked attachments added using the “Attach link to URI”? (I hope both, or at least the latter 🙂 )

Sure. Change the line above to:

$args = array( 'posts_per_page' => 6, 'cat' => 2 );

And change “2” to your category ID. Basically this is just a standard post query so you can change whatever you like. The posts_per_page => 6 thingy will make sure you don’t overfeed the slider – it doesn’t look as good with more than six posts.

Ah okay it appeared in the repo again.

Update: To test, I have just given the editor all user-related capabilities except promoting and deleting/removing users. No dice. I can’t get the Guest Authors page to show up for my editor.

Thanks for your response Griden.

The word “complex” should be a more appropriate though. As a theme developer, my main goal is to make the front-end interface intuitive.

Complex might be more appropriate. However, as an admin explaining others how to maintain a site using this theme, I can report that the “location” box feels not just complex but also inflexible to users. They would much rather simply use known features like “sticky” and various categories to manage what appears where on the front page. (So I made a start with that here.)

The theme doesn’t lock you in in any way. You can replace the Hybrid Core shortcodes with the core WordPress template tags/functions if you need to customise the theme. Hybrid Core is not a “layer”, it consists of optional features – you can choose what to use and what not.

This is true in a literal way, I guess — I’m still free to do whatever I want — but what I mean by lock-in is well exemplified by the case of the Hybrid shortcodes. They are use all over the template files. Customizing that aspect of the theme thus means editing all template files in which, say, [entry-author] occurs. Or it may mean editing the shortcode function itself, but that is not so trivial even given the transparent Hybrid code. (For instance, I find it quite hard to find out how to override the [entry-author] shortcode function with my own version in a child theme.)

You are problably right though that much could be learnt by reading through the Hybrid core code.

Here’s an answer. My goal was to make the Flickr Pick a Picture plugin work with an Oxygen child theme. FPP puts the attribution, including a link to the Flickr photo page, in the image post_excerpt. Alt text can’t include links so I was looking for a way to display the post_excerpt with the featured image in an unobtrusive way. I settled for a div that only appears when you hover over the image.

First, I was able to throw together a function for getting the post_excerpt() field (what I was calling the caption). Here is the function that I added to my functions.php:

function get_the_feature_caption() {
  global $post;

  $thumbnail_id    = get_post_thumbnail_id($post->ID);
  $thumbnail_image = get_posts(array('p' => $thumbnail_id, 'post_type' => 'attachment'));

  if ($thumbnail_image && isset($thumbnail_image[0])) {
    $caption = '<span>'.$thumbnail_image[0]->post_excerpt.'</span>';
  }
  return $caption;
}

Then in the post.php template of my Oxygen child theme, I include the following code:

if ( current_theme_supports( 'get-the-image' ) )
	$image= get_the_image( array( 'meta_key' => 'Thumbnail', 'size' => 'single-thumbnail', 'link_to_post' => false, 'image_class' => 'featured', 'attachment' => false, 'width' => 470, 'height' => 260, 'echo' => false ) );
$caption = get_the_feature_caption();
if ( !empty( $image ) ) {
	echo '<div class="img-feature">' . $image ;
	echo '<div class="feature-caption">' . $caption . '</div></div>';
}

Finally, in style.css of my child theme I use the following CSS to display the attribution in the lower right corner of the image — on hover only.

.img-feature { position:relative; }
.img-feature .feature-caption { display:none; }
.img-feature:hover .feature-caption {
	display:block;
	position:absolute;
	bottom:15px;
	right:0px;
	opacity:0.5;
	background-color:#000;
	padding:4px 8px;
	color:#fff;
	text-align:right;
}
.feature-caption a {
	color:#fff;
}
.feature-caption a:hover {
	color:#fff;
}

Hopefully this is helpful for others.
