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.
