alogblog’s MTy plugins: CCode and TCode for blocking comment/trackback spam for MT 3.2
Update:
Installed as instructed, although I wasn’t sure where to put the tag in the referenced comment templates. At first I put it above the closing /MTIfCommentsActive tag, but this generated an error because I was defining a field outside of the form tags. I then moved as shown below, and that worked. I went ahead and added to the default templates for Individual Archive (individual_entry_archive.tmpl) and Comment Preview (comment_preview_template.tmpl) making it easier to refresh each blog’s templates. Not sure why this was not in instructions, but it matches the recommendation for the site java script (site_javascript.tmpl.)
</div>
<input type=”hidden” name=”entry_id” value=”<$MTEntryID$>” />
<$MTEntryCCode$>
</form>
</MTEntryIfCommentsOpen>
</div>
</MTIfCommentsActive>
