Welcome to MTTags.com. Hopefully, you'll discover that this a really easy place to find information about Movable Type Template Tags. If you think we could be doing something better, please let us know! If this is your first time here, be sure to stop by the information desk, because we've got a growing todo list that might already include what you were about to suggest.
A variable tag that outputs a link to a tag search for the entry tag in context. The tag context is created by either an MTEntryTags or an MTTags block.
Like all variable tags, you can apply any of the supported global filters to MTTagSearchLink to do further transformations.
Example code
The example below shows each tag in a cloud tag linked to a search for other entries with that tag assigned. It can just as easily be used to link entry tags within an MTEntryTags loop
<h1>Tag cloud</h1>
<div id="tagcloud">
<MTTags>
<h<$MTTagRank$>>
<a href="<$MTTagSearchLink$>"><$MTTagName$></a>
</h<$MTTagRank$>>
</MTTags>
</div>
The search link will look something like:
http://example.com/mt/mt-search.cgi?blog_id=1&tag=politics
Using Apache rewriting, the search URL can be cleaned up to look something like:
http://example.com/tag/politics
See the relevant section of Chapter 5.4 in the User and Administration Manual entitled "Using Template Modules" for more examples related to entry tags, including the creation of "tag clouds".
