Yeah, I assumed it would only be used on text.
What I have never figured out is how to check for white space:
<?
function alphaNumeric($entered)
{
if(ereg("^[a-zA-Z0-9]*$", $entered))
{
return true;
}
}
$firstname="Jose";
$lastname="de la Cruz";
if($output=alphaNumeric($firstname) or $output=alphaNumeric($lastname)
{
echo "true";
}
?>
as a work around:
$lastname="de la Cruz";
$explode_lastname=explode(" ", $lastname);
$new_lastname=implode("", $explode_lastname);
if($output=alphaNumeric($new_lastname))
{
echo "true";
}
