Validate::uri doesn't seem to work

I'm pretty much a newbie to PEAR, trying to run some code from a book which utilizes the Validate package. Two of the form fields validate just fine, but uri does not. Is this a problem with the package, or am I doing something wrong? Here is the relevant code from my script: $errors = array('name'=>'','email'=>'','uri'=>''); if ( !Validate::uri($_POST['uri']) ) { $errors['uri']=' class="error"'; } and from the HTML form that uses the above code: <div> <label<?php echo ($errors['uri']); ?>>Website:</label> <span> <input type="text" name="uri" value="<?php echo(@$_POST['uri']);?>"> </span> </div> ~8^) Pat Wong http://www.napathon.net/ - Music Around The World For collecting tips, trade and want lists, album reviews and more. http://www.techtipscentral.net/CDTrusteeIntro.asp - Showcase your music collection on your website.
