WordPress.org

This simple jQuery-based plugin adds a list of existing (already used) tags with posts count for each tag into "Tags" box on new/edit post form. No more hard time remembering your hundreds of tags - simply click the one you need to add it to the post. Clicked tags are removed from tags list after they inserted into a post - so no worries about inserting one tag several times. No tuning and customizing needed - it just works as it is. Also, you now can hover a tag with mouse pointer to get a short list of five last posts tagged by it.

Changelog

v.1.14 - Made some changes in paths, cause automatic plugin update feature seems to move updated plugin from /wp-content/plugins/ to /wp-content/plugins/wp-existing-tags/. Now installation require you to put wp-extags.php into /wp-content/plugins/wp-existing-tags/ directory or manually edit paths after update to point to your custom directory.

v.1.12 - Fix: in_array() wrong datatype warning occured when editing post with no tags on it.

v.1.11 - Made some minor tweaks: clicked tags are removed from tags list after they inserted into a post; when editing, tags already assigned to the post do not appear in the list.

v.1.1 - Now prints number of posts for each tag. Also, you now can hover a tag with mouse pointer to get a short list of five last posts tagged by it.

v.1.0 - Initial version, basic functionality.
