Passing the value of selected radio button from one jsp to another
Hi All,
I am trying to pass the value of selected radio button from one jsp page to another but my code is not working.
Below is my code:-
Code:
<%@ page import="java.sql.*" %>
<%@ page import="java.io.*" %>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<style></style>
<%
int i=1;
String url = "jdbc:mysql://127.0.0.1:3306/Quiz";
String username1="root";
String password1="root";
PreparedStatement st = null;
ResultSet results = null;
int iQuestionID=3;
try {
Class.forName("com.mysql.jdbc.Driver");
Connection con= DriverManager.getConnection(url,username1,password1);
String sql="SELECT Questions.Question, Questions.option1, Questions.option2,Questions.option3, Questions.option4,Questions.correctanswer FROM Questions order by RAND() limit ?";
st = (PreparedStatement) con.prepareStatement(sql);
st.setInt(1,iQuestionID);
results = st.executeQuery();
while (results.next()) {
String r1, r2, r3, r4, r5,r6;
r1 = results.getString(1);
r2 = results.getString(2);
r3 = results.getString(3);
r4 = results.getString(4);
r5 = results.getString(5);
r6 = results.getString(6);
%>
<br/>
<center>
<form name="form1" method="post" action="Results.jsp" >
<table border="1" width="500px" bgcolor="white" cellspacing="0" cellpadding="0">
<tr>
<td width="100%">
<h2 align="center"><font color="red">Online Quiz Application</font></h2>
<b>Select Correct Answer</b>
<table border="0" width="500px" cellspacing="2" cellpadding="4">
<tr>
<td width="50%"> Question:</td>
<td><input type="hidden" name="correctAns<%= i %>" value="<%= results.getString(6) %>" /></td>
</tr>
<tr>
<td><%= results.getString(1) %></td></tr>
<tr>
<td>
1: <input type="radio" name="a<%= i %>" id="a<%= i %>" value="<%= results.getString(2) %>" /></td>
<td><%= results.getString(2) %></td></tr>
<tr>
<td>
2: <input type="radio" name="a<%= i %>" id="a<%= i %>" value="<%= results.getString(3) %>" /></td>
<td><%= results.getString(3) %></td></tr>
<tr>
<td>
3: <input type="radio" name="a<%= i %>" id="a<%= i %>" value="<%= results.getString(4) %>" /></td>
<td><%= results.getString(4) %> </td></tr>
<tr>
<td>
4: <input type="radio" name="a<%= i %>" id="a<%= i %>" value="<%= results.getString(5) %>" /> </td>
<td> <%= results.getString(5) %> </td></tr>
</table>
</td>
</tr>
</table>
<br/>
<% if (i==iQuestionID)
{
%>
<INPUT type = "submit" name="addSubmit" value = "Press to Submit">
<% } %>
</form>
</center>
<%
i++;
}
results.close();
con.close();
}catch (Exception ex) {
ex.printStackTrace();
}finally {
} %>
</body>
</html>
And the code in Results.Jsp
<%
String id[]= new String [5];
for (int i=1;i<5; i++)
{
id[i]=request.getParameter("a"+i);
out.println(id[i]);
}
%>
But in Results.jsp , I am getting null values.
I even tried the code with servlets.I was able to display the questions of quiz but I am unable to fetch the value of selected radio button.
Any help in correcting the above jsp code so that I can fetch the value of selected radio button will be much appreciated.
Thanks
