External Links

An icon can be added to the external links.

Installation:

Unpack and upload it to the /wp-content/plugins/ directory.
Activate the plugin through the 'Plugins' menu in WordPress.

Features:

• Process all outgoing links, rather than only those within your entries' content.
• You can use a class="noicon" attribute on links to override the link icon.
• Open outgoing links in new windows. Note that this can damage your visitor's trust towards your site in that they can think your site used a pop-under.
• Add rel=nofollow to the links. This is not very nice for those you're linking to, but useful to avoid PR leak.

What is new in this release:

• Domains to Exclude no longer assumes subdomains meaning subdomains need to be specifically excluded now.
• Entry of Domains to Exclude now allows separation by comma, space, newline/return, and tab. It will convert into a CSV list.
• Fixed placeholder links (href="#") not being excluded from processing correctly.
• Fixed plugin version number not being updated in the database options correctly.

What is new in version 6.4:

• New setting to specify domain(s) to be excluded from any processing. props Brian Wilson
• Remove multi-site check that was causing all links to be deemed internal.

What is new in version 6.3:

• Changed link detection to err on the side of a link being local rather than external to avoid false positives.
• Fixed double inclusion of class attribute under certain link attribute ordering conditions.

What is new in version 6.2:

• Additional performance changes for long post/page when Apply Globally is off.
• Links with no anchor text will have nofollow and/or target set, but no external icon.
• Improved detection and handling of anchor links as internal.
• Initial support for AddThis placeholder links.

What is new in version 6.1:

• The nofollow attribute was not being set if a certain combination of the global, follow comments, set nofollow settings were set.
• Backtracked and removed the Follow Comments functionality. It's usage was limited to certain cases and if Apply Globally was on, then it was disabled. Supporting it was adding too complex logic.

What is new in version 6.0.1:

• Fixed:
• Plugin decided to break classes on embedded images.

What is new in version 5.5.1:

• Additional tweak to global callback processing.

What is new in version 5.4.1:

• Adds a few HTML comments in the page source to ensure hooks are being called.

What is new in version 5.3:

• Fix:
• Conflict with Auto Thickbox plugin that would result in text widgets still being filtered even though option was turned off
• Ensure this plugin filter is executed way back in the change to prevent other plugins/themes from reversing our changes

What is new in version 5.2:

• Further updates to the link attribute parsing code.

What is new in version 5.0:

• Completely replaced the mechanism for parsing links to resolve the various errors that have been occurring with different external services' link attributes
• Added new option to apply to text widgets in addition to content and comment links. This will now handle 95% of the external link cases and allow for Apply Globally to be left off.

What is new in version 4.2:

• WP 3.6 compatibility.
• PHP 5.4 compatibility.
• Fixed issue with parsing of links with non-standard (class, href, rel, target) attributes included in the tag.

What is new in version 4.0.6:

• WP 3.0.1 compatibility.

What is new in version 4.0.4:

• Force a higher pcre.backtrack_limit and pcre.recursion_limit to avoid blank screens on large posts.

Requirements:

• WordPress 2.8 or higher
