Today, I will teach you how to create log-in and sign-up using tab control. We will be using CSS for the design of the tab menu and smooth transition using jQuery.
This is the basic implementation of CSS and jQuery.
Below are the step by step processes in making of this project.
1.Create a CSS file for the layout of the design. Name it “style.css”.
[css]
body {
font-family:Arial, Helvetica, sans-serif;
font-size:12px; background-color:#eee;
}
#wrap{
width:500px;
position: center;
padding: 12px;
}
#tab-menu{
height:40px
}
#content{
background-color:#FFF;
}
.tab-link{
background: #dedede;
display: block;
height: 40px;
line-height: 40px;
text-align: center;
width: 80px;
float: left;
font-weight: bold;
}
.tab-active{
background-color:#FFF;
}
#login-box{
height:300px;
padding:10px;
}
#signup-box{
height:300px;
padding:10px;
display:none;
}
[/css]2.Create a design for login and registration form in the tab control. Name it “index.php”.
[html]
<!-- css extension -->
<link rel="stylesheet" type="text/css" href="css/bootstrap.min.css">
<link rel="stylesheet" type="text/css" href="style.css">
<!-- wrap -->
<div id="wrap">
<h1><a href="itsourcecode.com">IT Sourcecode</a></h1>
<!-- menu -->
<div id="tab-menu">
<a href="#" id="login" class="tab-link tab-active">Log-in</a>
<a href="#" id="signup" class="tab-link">Sign-up</a>
</div>
<!-- end menu -->
<!-- content -->
<div id="content">
<!-- login tab -->
<div id="login-box"><h1>Log-in Form</h1>
<form role="form" action="#" method="post">
<div class="form-group">
<label class="sr-only" for="form-username">Username</label>
<input type="text" name="form-username" placeholder="Username..." class="form-control" id="form-username">
</div>
<div class="form-group">
<label class="sr-only" for="form-password">Password</label>
<input type="password" name="form-password" placeholder="Password..." class=" form-control" id="form-password">
</div>
<button type="submit" name="login" class="btn">Login!</button>
</form>
</div>
<!-- end login tab -->
<!-- signup tab -->
<div id="signup-box"><h1>Sign-up Form</h1>
<form role="form" action="#" method="post" >
<div class="form-group">
<label class="sr-only" for="fname">Name</label>
<input type="text" name="fname" placeholder="Full name..." class="form-control" id="fname">
</div>
<div class="form-group">
<label class="sr-only" for="user-name">Username</label>
<input type="text" name="user-name" placeholder="Username..." class="form-control" id="user-name">
</div>
<div class="form-group">
<label class="sr-only" for="user-pass">Password</label>
<input type="password" name="user-pass" placeholder="Password..." class="form-control" id="user-pass">
</div>
<button type="submit" name="register" class="btn">Submit</button>
</form>
</div>
<!-- end signup tab -->
</div>
<!-- end content -->
</div>
<!-- end wrap -->
[/html]3. Create a script for the transition of the tab control. Do this under the extension of jQuery.
[jquery]
<!-- jquery extension -->
<script type="text/javascript" src="jquery/jquery.min.js"></script>
<script type="application/javascript">
$(document).ready(function(){
if(action=='signup') {
$("#login").removeClass('tab-active');
$("#signup").addClass('tab-active');
$("#login-box").slideUp();
$("#signup-box").slideDown();
}else{
$("#signup").removeClass('tab-active');
$("#login").addClass('tab-active');
$("#signup-box").slideUp();
$("#login-box").slideDown();
}
});
});
</script>

Frequently Asked Questions
How does this PHP login or registration system work?
User signup form (with email verification optional), password hashing via password_hash() / password_verify(), login form with session_start(), remember-me cookie, logout, password reset via emailed token.
What PHP and MySQL versions does this project require?
Most projects in this batch run on PHP 7.4 to PHP 8.2 with MySQL 5.7+ or MariaDB 10+. A few older projects need PHP 5.6 (deprecated, use XAMPP 7.x). To run: install XAMPP / WAMP / Laragon, extract project to htdocs, import the included .sql file via phpMyAdmin, edit the connection file (usually config.php or db_connect.php) with your DB credentials, browse to the project URL in your browser.
How do I set up the database for this PHP project?
Open phpMyAdmin (http://localhost/phpmyadmin/ on XAMPP), create a new empty database with the name specified in the project’s config.php. Click the Import tab, choose the included .sql file, click Go. Then edit config.php (or includes/connection.php) with: ‘localhost’, your MySQL username (usually ‘root’), your MySQL password (usually blank for XAMPP), and the database name.
Can I use this PHP project for a BSIT capstone or thesis?
Yes, but extend it. A bare CRUD app is too narrow for full capstone scope. Add: user roles via session checks, reports/dashboards (Chart.js + AJAX), PDF exports (TCPDF library), email notifications (PHPMailer), real domain extension (analytics, audit log, multi-branch support). Pair with Chapter 1-5 documentation matching your panel’s rubric.
Why am I getting ‘connection error’ or ‘undefined function mysqli_connect’?
Three common PHP issues: (1) Connection error: Apache + MySQL services not running in XAMPP control panel, OR database name in config.php does not match what you created in phpMyAdmin. (2) ‘undefined function mysqli_connect’: MySQL extension not enabled, in php.ini uncomment extension=mysqli (then restart Apache). (3) ‘No such file or directory’: MySQL socket path wrong, use 127.0.0.1 instead of localhost in the connection string.
Where can I find more PHP projects with source code?
Browse the PHP Projects hub for the full library (300+ vanilla PHP systems). For modern PHP MVC alternatives see Laravel Projects (74 systems) or CodeIgniter Projects (32 systems). For BSIT-focused capstone idea lists see 150 Best Capstone Project Ideas.
