REGISTRATION AND LOGIN PAGE
The "Registration and Login Form" is a simple web-based project. As we know that in almost every web-based project we require a "SIGN UP & LOGIN PAGE".
So in this blog, we will see about this, and if haven't watched the complete tutorial of it on youtube then click here👉[[ REGISTRATION AND LOGIN FORM TUTORIAL ]]
- Initially for running SIGN UP PAGE, we require signup.jsp and signupServlet.java. And also we have to create a database for it to store the user detail.
DATABASE CODE:
create database youtube;
use youtube;
create table login(username varchar(50),password varchar(50));
signup.jsp code [JSP code] :
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Sign up</title>
<script type="text/javascript">
function validate()
{
var email=document.getElementById("email").value;
var pass=document.getElementById("pass").value;
var cpass=document.getElementById("cpass").value;
if(email=="")
{
document.getElementById("emailerror").innerHTML="Please enter Email...";
return false;
}
else
{
document.getElementById("emailerror").innerHTML="";
}
if(pass=="")
{
document.getElementById("passerror").innerHTML="Please enter password...";
return false;
}
else
{
document.getElementById("passerror").innerHTML="";
}
if(pass.length<5 || pass.length>8)
{
document.getElementById("passerror").innerHTML="Password should be in betwwen 5 to 8 character..";
return false;
}
else
{
document.getElementById("passerror").innerHTML="";
}
if(cpass=="")
{
document.getElementById("cpasserror").innerHTML="Please re-enter password...";
return false;
}
else
{
document.getElementById("passerror").innerHTML="";
}
if(cpass != pass)
{
document.getElementById("cpasserror").innerHTML="please enter same password";
return false;
}
else
{
document.getElementById("passerror").innerHTML="";
}
return true;
}
</script>
</head>
<body>
<div align="center">
<fieldset>
<%
String status =(String)request.getAttribute("status");
if(status != null)
{
out.println(status);
}
%>
<legend><h1>Sign up</h1></legend>
<form onsubmit="return validate()" action="signupServlet" method="post">
<table>
<tr>
<td>Email : </td>
<td><input type="email" id="email" name="email"></td>
<td><span style="color:red" id="emailerror">*</span></td>
