firstname and lastname are being submitted from a HTML form.
In PHP i want to check that both of them must be atleast 3 characters long and maximum upto 18 characters.
How can i check it in an if else
statement
Example code is below
$f = $_POST['firstname'];
$l = $_POST['lastname'];
if((strlen($f) < 3 || strlen($f) > 16) && (strlen($l) < 3 || strlen($l) > 16))
{
echo "Firstname and lastname must be between 3 and 16 characters";
exit();
}
It is not working what i have done wrong.....
Thanks for help and I hope you understand my problem
