You should only use the uri filter for encoding query values in the url. e.g. [% term = 'Ben & Jerry' %] <a href="http://foo.com/search?term=[% term | uri %]">...</a> This generates: <a href="http://foo.com/search?term=Ben%20%26%20Jerry";>...</a> This stops the '&' in the search term from being confused with the URL parameter separator. But the URI filter is too aggressive for encoding complete URLs. The only time you would want to do that is if you're using a URL as a query parameter. Consider this rather contrived example: [% term = 'http://www.google.co.uk/search?q=uri+encoding&ie=utf-8' %] <a href="http://foo.com/search?term=[% term | uri %]">...</a> Which produces: <a href="http://foo.com/search?term=http%3A%2F%2Fwww.google.co.uk%2Fsearch%3Fq%3Duri%2Bencoding%26ie%3Dutf-8";>...</a> > using "| url" > =========== Yes, the url filter is for encoding complete URLs. It's a less aggressive form of the uri filter that attempts to Do The Right Thing. But be warned that there's no such thing as URL encoding in formal terms so the Right Thing is somewhat arbitrary. > - fails W3C validation with the error below.

You must pass it through the html filter to escape any '&' characters as '&' [% my_url | html %] To clarify, this URL: http://foo.com/search?term=Ben%20%26%20Jerry&page=20 Must be embedded in HTML as: <a href="http://foo.com/search?term=Ben%20%26%20Jerry&page=20";>...</a> ^^^^^ The most reliable way to generate URLs is to use the URL plugin. It takes care of all this mess for you: [% USE search = URL('http://foo.com/search') %] <a href="[% search_link(term="Ben & Jerry", page=20) %]">GO</a> This generates: <a href="http://foo.com/search?page=20&term=Ben%20%26%20Jerry";>GO</a> Which is the correct HTML encoded representation of a URL with URI encoded query terms.
