You need to add a space to your character class: if (ereg("^[a-zA-Z0-9_ ]{2,30}$", $name)) { return true; } However, note also: pattern matching such as this is faster and more flexible if you use the preg_* functions instead of the ereg_* functions: if (preg_match('/^[a-z0-9_ ]{2,30}$/i', $name)) { return true; } will perform faster, and gives you case insensitivity with the 'i' switch following the regexp. -- Matthew Weier O'Phinney | mailto:matthew@garden.org Webmaster and IT Specialist | http://www.garden.org National Gardening Association | http://www.kidsgardening.com 802-863-5251 x156 | http://nationalgardenmonth.org
