Question

mysql code :
CREATE TABLE DEST_C(ID_DEST_C INT(5),CATEGORY VARCHAR(45))
CREATE TABLE DEST(ID1_DEST INT(6),ID2_DEST INT (6),COUNTRY VARCHAR(40),CITY VARCHAR(40),URL VARCHAR(5400));
jsp form code:
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>create dest</title>
</head>
<body>
<html>
<head>
<title>CREATE DESTINATION</title>
<meta charset="UTF-8">

<h1> CREATING DESTINATION </h1>
<form name="createdest" method="get" action="create dest code.jsp">
Country: <input type="text" required name="id8" /> <br>

<input type="submit" value="CREATE DESTINATION" />
<br>
</form>
<SCRIPT LANGUAGE="javascript">
function KeepCount() {
var NewCount = 0
if (document.createdest.id5.checked)
{NewCount = NewCount + 1}
if (document.createdest.id6.checked)
{NewCount = NewCount + 1}
if (document.createdest.id7.checked)
{NewCount = NewCount + 1}
if (NewCount == 3)
{
alert('Pick Just Two Please')
document.createdest; return false;
}
}
</SCRIPT>

A very simple solution would be to assign a binary value to your checkboxes. So rather than 1,2,3 you could use 1,2,4. Then you would sum the values of the selected boxes and save this unique value.
As in your code:
`input type="checkbox" name="id5" value="1" (...)` `input type="checkbox" name="id6" value="2" (...)` `input type="checkbox" name="id7" value="4" (...)`
The truth table below shows you the different values.
id: ID5 ID6 ID7 Sum
value: 1 2 4
x 1
x 2
x x 3
x 4
x x 5
x x 6
The solution is not SQL related, but quite frankly, neither is the question... Good luck!
