First we have to create users table that will hold all user information like name, username, password, and email.

  `name` varchar(128) NOT NULL,
  `username` varchar(64) NOT NULL,
  `password` varchar(64) NOT NULL,
  `email` varchar(124) NOT NULL,
  PRIMARY KEY (`id`)


This following html code resides in index.php file. That file holds the basic of registration form.

<!doctype html>
<html lang="en">
  <meta charset="UTF-8">
  <title>Sign Up</title>

  <!-- bootstrap style sheet -->
  <link rel="stylesheet" type="text/css" href="assets/css/bootstrap.min.css">

  <!-- general styling -->
  <link rel="stylesheet" type="text/css" href="assets/css/style.css">

  <div class="container">
    <div class="main">

      <div class="alert alert-error">
        <!-- error message will be shown here -->

      <form class="form-horizontal" action="" method="post">

        <div class="control-group">
          <label for="name" class="control-label">
            <span>Full Name</span> <span class="required">*</span>
          <div class="controls">
            <input type="text" name="name" id="name" required placeholder="Full name">

        <div class="control-group">
          <label for="username" class="control-label">
            <span>Username</span> <span class="required">*</span>
          <div class="controls">
            <input type="text" name="username" id="username" required placeholder="username">

        <div class="control-group">
          <label for="password" class="control-label">
            <span>Password</span> <span class="required">*</span>
          <div class="controls">
            <input type="password" name="password" id="password" required placeholder="Password">

        <div class="control-group">
          <label for="password2" class="control-label">
            <span>Repeat password</span> <span class="required">*</span>
          <div class="controls">
            <input type="password" name="password2" id="password2" required placeholder="Repeat Password">

        <div class="control-group">
          <label for="email" class="control-label">
            <span>Email</span> <span class="required">*</span>
          <div class="controls">  
            <input type="email" name="email" id="email" required placeholder="Email Address">

        <div class="controls">
          <input class="btn btn-primary" id="submit" type="submit" value="Sign Up!">




  <!-- jquery library include -->
  <script src=""></script>

  <!-- jquery validation plugin include -->
  <script src="assets/js/validation.min.js"></script>

  <script src="assets/js/script.js"></script>


Take a look on the above html markup, we used required attribute on input fields. It is a html5 attribute. It tells the browser that this field it required and user must have to fill this field.


The following JavaScript resides in script.js file. This file holds jQuery Validation plugin's configurations. Here we needs to set some rules. Take a look on the comments to know more about the rules. We will also need to create a function called ajaxSubmit. This function will submit the form asynchronously through ajax request.


  var form  = $('form');
  var submit   = $('#submit');
  var alert  = $('.alert');

  // validate form
    // validation rules
    rules: {
      // name field (required , minimum length 3)
      name: {
        required: true,
        minlength: 3
      // username field (required , minimum length 3, max 8)
      username: {
        required: true,
        minlength: 3,
        maxlength: 8,
      // password field (required , minimum length 6, max 16)
      password: {
        required: true,
        minlength: 6,
        maxlength: 16
      // password2 field must be equal to password field
      password2: {
        equalTo: '#password'
      // email field only required
      email: 'required'
    // submit ajax request
    submitHandler: ajaxSubmit

  * ajax submit function
  * sending simple ajax request

  function ajaxSubmit() {
      url: 'ajax.php',
      type: 'POST',
      dataType: 'json',
      // form serialize data
      data: form.serialize(),
      beforeSend: function(){
        submit.val('Sending...').attr('disabled', 'disabled');
      success: function(data){
        if ( data.status === 'success' ) {
          // if responce status == success redirect to success page
        } else {
          // not success! show error messages
          submit.val('Sign Up').removeAttr('disabled');
      error: function(){
        // show error message
        alert.html('Sending request fail').fadeIn();
        submit.val('Sign Up').removeAttr('disabled');


We are now ready to write some php code. The following code is resides on ajax.php file. This file receives ajax request and checks some validity.

include 'config.php';
include 'function.php';
# mysql db connect

header('Content-type: application/json');

  if ($_POST['name'] !== '' and $_POST['username'] !== '' and $_POST['password'] !== '' and $_POST['email'] !== '' )
    if ($_POST['password'] === $_POST['password2']) {
      # prevent sql injection
      $name     = mysql_real_escape_string($_POST['name']);
      $username   = mysql_real_escape_string($_POST['username']);
      $password   = mysql_real_escape_string($_POST['password']);
      $email     = mysql_real_escape_string($_POST['email']);

      # username exist or not
      if (!user_exist($username))
      {  # insert new user
        if (inser_new_user($name, $username, md5($password), $email))
        {  # throw success status
          # throw errors
        } else { json_status('Request not complete'); }
      } else { json_status('Username already exist'); }
    } else { json_status('Passwords are not matched'); }
  } else { json_status('You must complete all the fields'); }
Note: It is not a secure way to process registrations data form server side. If you want to implement it in your real life project you need to do more validation.
