Login or Signup with Jquery and PHP

Some users doesn't like to filling the registration form. So that I had implemented login and singup fields in same block just controlling with jquery and PHP. It's is very simple javascript and basic PHP code.

Download Script     Live Demo

Javascript code
$('#signup').click(function(){} - signup is the ID of the radio. Using $("#login_block").hide() hide the login block and $("#signup_block").show() shows signup block.
<script type="text/javascript" src="http://ajax.googleapis.com/
<script type="text/javascript">




Contains simple html code. signup_block style display none.
<form method="post" action="loginup.php">

<label>Email</label> <br/>
<input type="text" name="email"/><br />
<input type="radio" name="choose" id="login" checked="checked"/> I have an account <br />
<input type="radio" name="choose" id="signup"/> I am new!<br />

<div id="login_block">
<label>Password</label><br />
<input type="password" name="password" id="password"/><br/>
<input type="submit" value=" Login "/>

<div id="signup_block" style="display:none">
<label>Choose password</label><br/>
<input type="password" name="newpassword" id="newpassword" /><br/>
<input type="submit" value=" Signup "/>


$email = $_POST['email'];
$password = $_POST['password'];
$newpassword = $_POST['newpassword'];

if($_POST['password'] && $_POST['email'])
$sql=mysql_query("SQl select statement");
echo "Login success";

else if($_POST['newpassword'] && $_POST['email'])
$sql=mysql_query("SQl Insert values statement");
echo "Registration Success";

Why you use document.getElementById ?

why not use jQuery selector?

Simple but very usefull.

bart said...

No offence, but you're learning PHP & JS but can't set proper labels in HTML?

Amit said...

from a usability pov, I think you have really simplified this quite well.

This is so simple. If you make something more, like: control the error with ajax, sending email, ... then the tutorial will be better.

Tom said...

1. please link the labels to the input fields
2. make your js code more reusable for others
3. why don't you modify the given form instead of showing or hiding the extra block?
4. sanitize user input data in php !!! (high security risk)

Good tutorial. Great thinking UX-wise !

Good code and learning curve for beginner. I just want to mention for beginners that, all times to keep in mind filter input before pass user inputted value to mysql. Otherwise mysql injection may happen.
