Thanks Steve,
It is not my choice re javascript in this case
I have tried to use the functions is_int($input_var) and
is_integer($input_var) and the !versions as you suggest but with
failures.
____Example 1_____
if ((@!$submit) || (!is_int($input_var)) )
{
echo "error";
include "get_id.php";
}
else {
________
_____Example 2_____
if ((@!$submit))
{
echo "error";
include "get_id.php";
}
elseif (is_int($num)) {
_____________
There were no problems before attempting validation with is_int() and
is_integer(). The integer validation was being with a javascript and
the creation of the variable was OK.
Further advise appreciated.
Tim
