Smarter Cleaner Gallery

(8)

Justin Tadlock’s Cleaner Gallery plugin fixes the semantics of the WordPress built-in gallery feature by placing all of the gallery related CSS in an external file instead of the inline CSS produced by WordPress core.

However, the problem is that this CSS file is loaded on every page request. Therefore, until WordPress supports combining all CSS files into one, here is a quick way to hide this CSS file on all pages that don’t contain a gallery (line 128 of cleaner-gallery.php):

Note: this will add cleaner-gallery.css only on single post and page views (not indexes or archives).

add_action('wp_head', 'cleaner_gallery_head', 0);
function cleaner_gallery_head() {
	global $post;
	if (strstr($post->post_content, '[gallery'))
		wp_enqueue_style( 'cleaner-gallery', CLEANER_GALLERY_URL . '/cleaner-gallery.css', false, 0.7, 'all' );
}

Hopefully, Justin can incorporate this into the next release of this handy plugin.

Automatically Escape HTML Entities of Code Fragments in Comments

(7)

Update: Ryan has made this into a plugin — Code Comments.

Add this to your theme’s functions.php to allow readers post fragments of code in their comments (wrapped in <code>...</code>) which are automatically encoded (think of < and <)

add_filter('pre_comment_content', 'encode_code_in_comment');

function encode_code_in_comment($source) {
  $encoded = preg_replace_callback('/<code>(.*?)<\/code>/ims',
  create_function(
    '$matches',
    '$matches[1] = preg_replace(
        array("/^[\r|\n]+/i", "/[\r|\n]+$/i"), "",
        $matches[1]);
      return "<code>" . htmlentities($matches[1]) . "</code>";'
  ),
  $source);

  if ($encoded)
    return $encoded;
  else
    return $source;
}

Worth noting:

• Everything wrapped in <code>...</code> is encoded.
• Line breaks after opening <code> and before closing </code> are removed in order to avoid unnecessary <br /> tags.

Multiple Galleries per Post/Page

(11)

Ever wanted to have multiple galleries on the same post or page? Currently most of the solutions require you to manually edit gallery shortcode and add something like include="img_id_1 img_id2". Luckily, WordPress 2.9 will have this include/exclude feature built in core, but you still don’t have an easy way to select images which to include or to insert multiple galleries.

Therefore, I created a plugin called Multiple Galleries which adds checkboxes next to images in the Insert Gallery window which makes selecting images to be included in galleries fast and easy. If no checkbox is selected, all images are included.

I created this plugin because I am designing a new WordPress theme for designers, artists, architects and all of the creative types where the ability to have multiple galleries per portfolio entry is very important.

Enable Automatic Updates for Plugins Hosted by Developers

(12)

Currently WordPress doesn’t offer an easy way for plugins which are not hosted on wordpress.org to use its built-in automatic update feature.

Fortunately, I have found a quick and simple way to add this functionality to any plugin and allow plugin authors to take a complete control over when and how the updates are released. Read more »
