       // check validity of date
    if(empty($unix_date)) {
        return "Bad date";
    }

    // is it future date or past date
    if($now > $unix_date) {
        $difference     = $now - $unix_date;
        $tense         = "ago";

        $difference     = $unix_date - $now;
        $tense         = "from now";
    }

    for($j = 0; $difference >= $lengths[$j] && $j < count($lengths)-1; $j++) {
        $difference /= $lengths[$j];
    }

    $difference = round($difference);

    if($difference != 1) {
        $periods[$j].= "s";
    }

    return "$difference $periods[$j] {$tense}";
}

call this function as 

$date = "2010-07-16 17:45";
$result = time_difference($date); // 1 year ago

</html>

In above html code the feedback form and button code is added at the top in tag as we want the feedback button at right side of the page and feedback form over all the page content.

CSS Style style.css

#feedback_lightbox
{
	width:350px;

{
margin:10px 0px 10px 0px;
border:1px solid green;
padding:10px;
color:green;
overflow:hidden;
display:none;
}

You can edit this stylesheet code to improve the appearance of the form elements.

Jquery Code

code is included inside the js/script.js file

	$(document).ready(function(){
		/* Show Feedback form when feedback button clicked */
		$('#feedback_button a').click(function(){
			$('#feedback_overlay_box').show();
		});
		/* Hide Feedback form when close button clicked */
		$('#feedback_close a').click(function(){
			$('#feedback_overlay_box').hide();
		});

		/* Following code will be called when user submit the feedback form */
		$('.wp_feedback_form').submit(function(){
		var url = $(this).attr('action');
		var update = url.split("#")[1];
		var name = $("#feedback_name").val();
		var email = $("#feedback_email").val();
		var website=$("#feedback_website").val();
		var message=$("#feedback_message").val();
		var dataString = 'email='+ email + '&name=' + name+'&website='+website+'&message='+message;
		var emailFormat = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i;

		/* In first part of this code we validated inputs entered by user. */
		if (email == '' || name == '' || website=='') {
			$("#feedback_error").fadeIn(200).html("All fields are required !");
		}else if (email.search(emailFormat) == -1) {
			$("#feedback_error").fadeIn(200).html("Invalid Email Address!");
		}

		else
		{
			/*
			Following code will send a jquery ajax request to the send_email.php file,
			with user inputs */
			$.ajax({
				type: "POST",
				url: "" + url + "",
				data: dataString,
				success: function(response){
			/* Response is add to the #feedback_response div */
					$('#feedback_response').html(response);

				},
				complete: function(){
			/* On completion of ajax request following methods are called. */
					$("#feedback_error").fadeOut(200);
					$("#feedback_response").fadeIn(200);
					$(".feedback_text").val('');
					}

			});

		}
		return false;
		});
	});

PHP CODE

For email sending we will use php mail()

 <?php
	$to="mail@website.com"; /* All the emails will be sent to this email address. */
	/* Get all the field values */
	$from=$_POST['email'];
	$name=$_POST['name'];
	$website=$_POST['website'];

	$subject="Feedback Posted on  Your Website"; /* Subject added to email.*/
	$success_message="Thanks For your feedback!."; /* Success message displayed on the form.*/
	$info =addslashes($_POST['message']);
	$message="<h2>".$subject."</h2>";
	$message.="<p>Name = ".$name.'</p>';
	$message.="<p>Email = ".$from.'</p>';
	$message.="<p>Website = ".$website.'</p>';
	$message.="<p>Message = ".$info.'</p>';
	// To send HTML mail, the Content-type header must be set
	$headers  = 'MIME-Version: 1.0' . "\r\n";
	$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
	$headers .= 'From:'.$from;
	if (mail($to, $subject, $message,$headers)) {
	echo $success_message;
	}
	else
	{
		echo 'ERROR Sending Email. Please try again.';
	}

 ?>

You can use this feedback form code to get feedbacks from users. All your comment and suggestion will be appreciated.

So using this code you can calculate age by sending birth date as parameter. Or you can calculate difference between today’s date and any date in past.


function get_Age_difference($start_date,$end_date){

$text_colour = imagecolorallocate( $new_image, 255, 255, 0 );

header( "Content-type: image/jpeg" );
imagejpeg( $new_image );

imagecolordeallocate( $background );
imagedestroy( $new_image );?>

Create Image

Create image using the PHP function createimage(), function will create image with the dimensions of the image, namely its width and height in that order

Apply Colors

Next thing is to apply colors using the imagecolorallocate() function.
Colours are allocated using the imagecolorallocate() function. This function will automatically fill the background of the image with the colours you specified, and return an identifier for that particular colour. Subsequent calls to imagecolorallocate() will create a colour identifier for your colour.
imagecolorallocate() returns FALSE if the function fails for any reason.

Write Text On Image

We can write text on images using the function imagestring().
imagestring ( resource $image , int $font , int $x , int $y , string $string , int $color );
1] $image is image source
2] Font Can be 1, 2, 3, 4, 5 for built-in fonts in latin2 encoding
3] x-coordinate of the upper left corner.
4] y-coordinate of the upper left corner.
5] The string to be written.
6] A color identifier created with imagecolorallocate().

Display Image

Image is created using imagejpeg()
In this example i passed header( “Content-type: image/jpeg” ) as i want to create a jpg image.
Other functions are
1]imagepng()
2]imagegif()

Free Resources

Free individual resources which are created using the imagecolordeallocate() function and the image resource using the imagedestroy() function.
