That would have been my first choice also, however, with the #
and - being
legal, things like ctype_alnum and others don't work out.
[/snip]
Here is an example of something that I did before;
$alphachar = " abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
$ld1alpha = strspn($ld1, $alphachar);
if(strlen($ld1) != $ld1alpha){
$err[$i] = "The LD1 may only contain alpha characters.<br>\n";
$i++;
}
int strspn ( string str1, string str2) - Returns the length of the
initial segment of str1 which consists entirely of characters in str2.
You could add - and # to $alphachar
Now, in this case $ld1aplpha would be the same length as the string
length of the input field where the characters are contained in
$alphachar. This is used as one of the steps in a
verification/validation procedure on a large internal form.
Just another solution to the problem
HTH!
