USE `user_login`;

-- --------------------------------------------------------

--
-- Table structure for table `categories`
--

CREATE TABLE IF NOT EXISTS `categories` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `category_name` varchar(100) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

-- --------------------------------------------------------

  `category_id` int(11) NOT NULL,
  `right_answer` int(11) NOT NULL,
  `wrong_answer` int(11) NOT NULL,
  `unanswered` int(11) NOT NULL,

Integrate User Login, Regisration and Forget Password Functionality in Quiz Application:

As I said I had integarted my previous tutorial on User registration and Login Using PHP5, MySQLi, jQuery and Bootstrap in  this Online Quiz Using PHP. Please refer the above tutorial for detail integration.

If you may want integrate Social logins (i.e. Facebook, Twitter and Google Plus) in your Quiz Application, Please refer this following tutorial.

Timer Integration In Quiz Application:

I had removed timer in the previous version of Quiz application, and added new timer for this multiple choice quiz application with very few lines of jQuery script.

    var c = 60;
    var t;
    timedCount();
    function timedCount() {
    	var hours = parseInt( c / 3600 ) % 24;
    	var minutes = parseInt( c / 60 ) % 60;
    	var seconds = c % 60;
    	var result = (hours < 10 ? "0" + hours : hours) + ":" + (minutes < 10 ? "0" + minutes : minutes) + ":" + (seconds  < 10 ? "0" + seconds : seconds);
    	$('#timer').html(result);
        if(c == 0 ){
        	setConfirmUnload(false);
            $("#quiz_form").submit();
        }
        c = c - 1;
        t = setTimeout(function(){ timedCount() }, 1000);
    }

I had set my quiz application for 60 seconds. If you may want to change Quiz timings, then change in the following line.
For 10 Minutes

var c = 60*10;

For 20 Minutes

var c = 60*20;

For 1 hour

var c = 60*60;

PHP Flash Session Message Integration:

When user do some action in our application, we must properly communicate wheteher that action is success or failure to the user.

Assign your message in the Session like this…

session_start();
$_SESSION['success'] = 'Sample session message';

Display that message like this…

<?php if( isset( $_SESSION['error']) && !empty( $_SESSION['error'] )){ ?>
	<div class="message_error message_div">
		<p class="text-center"> <?php echo $_SESSION['error']; ?>  </p>
	</div>
<?php $s = 1;  ?>
<?php }elseif ( isset( $_SESSION['success']) && !empty( $_SESSION['success'] )){ ?>
<?php //print_r( $_SESSION );exit; ?>
	<div class="message_success message_div">
		<p class="text-center"> <?php echo $_SESSION['success']; ?> </p>
	</div>
<?php $s = 1; ?>
<?php }else{
	$s =0;
} ?>




<?php if($s){ $s = 0; ?>
	<script>
		$(document).ready(function(){
			$('.message_div').delay(5000).slideUp();
		});
    </script>
<?php } ?>

Once it displayed, we must unset that session using unset() function.

<?php unset($_SESSION['success'] ); unset($_SESSION['error']);  ?>
