There are two different kinds of escaping going on.</p> <p>It sounds like you're talking about the URL encoding that uses '%xx' to represent special characters.</p> <p>However, the html_escape function does something completely different. It takes a string and turns '&' into '&' and '<' into '<', etc., so that it can go into HTML without being interpreted as literal '&'s and '<'s.</p> <p>Escaping special characters in URLs using the '%xx' scheme is mandatory, otherwise they are not valid URLs.</p> </blockquote> <p>I've realized that the 'escaping' that you see happening is url encoding, and it shouldn't affect your query/sorting, etc. You can test it out by taking the encoded url and typing it into your browser.</p> <p>:escape => false disable html escaping, which means dangerous characters get converted to display codes, such as '&' into '&' and '<' into '<', etc.,</p> <p>And the "?" in your append should be "&":</p> <pre><code>+ "&direction=desc" </code></pre> <p>Hope this helps. =)</p>
