I use a javascript to do that for my forms:
if (window.RegExp) {
var reg = new RegExp("^[_0-9a-z]*$","gi");
if (!reg.test(f.elements['username'].value)) {
alert("Kullanici adi harf ve/veya rakamlardan
olusmalidir. Lutfen Duzeltiniz!");
f.elements['username'].focus();
return(false);
}
}
I am sure you could write something similar with PHP.....
