Link Indication


Link Indication adds CSS class attributes to external links and optionally specific attributes to any other link types such as, flickr, imdb, file extensions like .pdf or .zip, etc. Thereby you can indicate your links, e.g. by images, for characterizing your types of links. Furthermore you can add target=”blank” to all external links, rel=”nofollow” to specific hyperlinks or display websnapr preview thumbnails.

The plugin is applied at display time, not while a post is being saved. This means that this plugin can be integrated at any time, it will modify the rendering of existing posts and comments as soon as the plugin is enabled.

I installed this plugin when I first started with wordpress... It was 2.x something version. Still works with 4.9.2 ! EDIT: I recently upgraded my server to PHP7.0, this plugin broke my site. The workaround is quite easy. Edit the file link-indication.php Locate the following line (should be line 315): $final_stuff = eregi_replace('\[\[:space:\]\]+', ' ', $final_stuff); Change it to look like this: $final_stuff = preg_replace('/:space:+/', ' ', $final_stuff); Save it, the plugin is back for good !
