A little introduction
How I said this package is ready to use and contains these files:
- index.php: the launching soon page final interface (countdow + form)
- config.php: enables database connection
- insert.php: PHP code to add emails into a database table
- js/jquery-1.3.2.min.js: jQuery framework
- js/countdown.js: the countdown script
1. index.php
index.php is the final interface of your launching soon page. How I said it contains a countdown and a form to allow users to leave their emails.
The countdown script
In order to implement the countdown I used this dynamic countdown script that lets you count down to relative events of a future date/time. This future date, while the same for everyone, occurs differently depending on the time zone they're in. The result is here and it's fully customizable changing some lines of CSS code:
The only thing you have to do is to add this line of code in the <head> tag of the page:
<script type="text/javascript" src="js/countdown.js"></script>
Then, in the tag <body> add the following lines of code to display the countdown:
<div id="count_down_container"></div>
<script type="text/javascript">
var currentyear = new Date().getFullYear()
var target_date = new cdtime("count_down_container", "July 6, "+currentyear+" 0:0:00")
target_date.displaycountdown("days", displayCountDown)
</script>
<script type="text/javascript">
var currentyear = new Date().getFullYear()
var target_date = new cdtime("count_down_container", "July 6, "+currentyear+" 0:0:00")
target_date.displaycountdown("days", displayCountDown)
</script>
To set a target date you have to change this line modifying July 6 and the hour 0:0:00 with your target date (for example 25 december):
new cdtime("count_down_container", "July 6, "+currentyear+" 0:0:00")
...if your target date is 25 December the previous line becomes:
new cdtime("count_down_container", "December 25, "+currentyear+" 0:0:00")
If you want to change the style of the countdown you have to modify the following CSS classes:
.count_down{...}
.count_down sup{...}
.count_down sup{...}
In particular .count_down{} changes the format of the numbers and .count_down sup{} changes the style of the text "days", "hours", "minutes".
jQuery and the input form
Ok, the countdown is ready! Next step: add this line of code to include jQuery in the <head> tag of the page:
<script type="text/javascript" src="js/jquery-1.3.2.min.js"> </script>
Now, in the tag <body> add a simple form with an input field:
<form id="submit_leave_email">
<input id="input_leave_email" type="text" class="input_bg" value="Add your e-mail address"/>
<button type="submit" class="input_button">Update me</button>
</form>
<input id="input_leave_email" type="text" class="input_bg" value="Add your e-mail address"/>
<button type="submit" class="input_button">Update me</button>
</form>
...and add this layer to display a custom message when an user submit the form:
<div id="update_success">E-mail added!>/div>
...the result after the submission is here:
The form with the input field disappears with a nice fade-out effect and a success message appears in its place. Now, in the <head> tag, after the line of code that includes jQuery, add this script to enable ajax functionalities to insert emails added from users into a database table without reload the page:
<script type="text/javascript">
$(document).ready(function(){
$(document).ready(function(){
$("form#submit_leave_email").submit(function() {
var input_leave_email = $('#input_leave_email').attr('value');
$.ajax({
type: "POST",
url: "insert.php",
data:"input_leave_email="+ input_leave_email,
success: function(){
$("#submit_leave_email").fadeOut();
$("#update_success").fadeIn();
}
});
return false;
});
});
</script>var input_leave_email = $('#input_leave_email').attr('value');
$.ajax({
type: "POST",
url: "insert.php",
data:"input_leave_email="+ input_leave_email,
success: function(){
$("#submit_leave_email").fadeOut();
$("#update_success").fadeIn();
}
});
return false;
});
});
2. insert.php
insert.php contains some lines of PHP code to insert an email address into a database table. In this example I created a table EMAIL with just one attribute "email". PHP code is very simple:
<?php
if(isset($_POST['input_leave_email'])){
/* Connection to Database */
include('config.php');
/* Remove HTML tag to prevent query injection */
$email = strip_tags($_POST['input_leave_email']);
$sql = 'INSERT INTO WALL (email) VALUES( "'.$email.'")';
mysql_query($sql);
echo $email;
} else { echo '0'; }
?>
if(isset($_POST['input_leave_email'])){
/* Connection to Database */
include('config.php');
/* Remove HTML tag to prevent query injection */
$email = strip_tags($_POST['input_leave_email']);
$sql = 'INSERT INTO WALL (email) VALUES( "'.$email.'")';
mysql_query($sql);
echo $email;
} else { echo '0'; }
?>
Now, remember to modify your database connection parameters in config.php and upload all files on your testing server. Than load index.php and see the result!
