CodeIgniter Tutorial for creating Header ,Footer & display content..

(1)Download codeigniter from "http://www.codeigniter.com/download"

(2) create folder ci under path "c:/wamp/www"

(3) then extract zip file of CodeIgniter-2.2.1 into "ci" folder.

(means into following path=
"C:/wamp/www/ci")

(4)then go to browser & type

"localhost/ci/" (note: you will see welcome message )

(5)now understand Codeigniter sturcture:

It contains three main folder under "application" folder:

(a)controllers (handles all incoming Http requests,passes data to the views).

(b)views(Renders the Html output).

(c)Models(Encapsulate Business Logic,such as Interaction with database).

(6)now opend notepad type following code:
<h1> this is header </h1>

save file name as header.php & save this file under "views" folder.

(7) type code:
<h1>this is content </h1>

save file name as content.php & save this file under "views" folder.

(8) type code:

h1> this is footer </h1>

save file name as footer.php & save this file under "views" folder.

(9) now wirte following code :
<?php

class Hello extends CI_controller

{

public function one()

{

echo "this is one";

}
public function two()
{

$this->load->view('header.php');

$this->load->view('content.php');

$this->load->view('footer.php');

}

}

save this file as hello.php & save this file under "controllers" folder.

(10) Now open browser & to run one function of hello class

type following url:"Localhost/index.php/hello/one

output: this is one

(11)Now open browser & to run two function of hello class

type following url:"Localhost/index.php/hello/two

output:

this is header
this is content
this is footer

preg_match — Perform a regular expression match for email,name ,URL

see code below for example.php:

Read explanation of above used preg_match():

PHP - Validate E-mail

The easiest and safest way to check whether an email address is well-formed is to use PHP's filter_var() function.

In the code below, if the e-mail address is not well-formed, then store an error message:

$email = test_input($_POST["email"]);if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {  $emailErr = "Invalid email format"; }

PHP - Validate URL
The code below shows a way to check if a URL address syntax is valid (this regular expression also allows dashes in the URL). If the URL address syntax is not valid, then store an error message:

$website = test_input($_POST["website"]);if (!preg_match("/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i",$website)) {  $websiteErr = "Invalid URL"; }

PHP - Validate Name
The code below shows a simple way to check if the name field only contains letters and whitespace. If the value of the name field is not valid, then store an error message:

$name = test_input($_POST["name"]);if (!preg_match("/^[a-zA-Z ]*$/",$name)) {  $nameErr = "Only letters and white space allowed"; }

//function code:

function test_input($data) {   $data = trim($data);   $data = stripslashes($data);   $data = htmlspecialchars($data);   return $data;}

PHP script for Contact form validation

(1)write code for "contactform.php file":

<?php include 'validation.php';?>

<!DOCTYPE HTML>

<html>
<head>
<title>PHP Contact Form with Validation</title>
<link rel="stylesheet" href="css/style.css" />
</head>
<body>
<div class="container">
<div class="main">
<h2>PHP Contact Form with Validation</h2>
<form method="post" action="contactform.php">
<label>Name :</label>
<input class="input" type="text" name="name" value="">
<span class="error"><?php echo $nameError;?></span>
<label>Email :</label>
<input class="input" type="text" name="email" value="">
<span class="error"><?php echo $emailError;?></span>
<label>Purpose :</label>
<input class="input" type="text" name="purpose" value="">
<span class="error"><?php echo $purposeError;?></span>
<label>Message :</label>
<textarea name="message" val=""></textarea>
<span class="error"><?php echo $messageError;?></span>
<input class="submit" type="submit" name="submit" value="Submit">
<span class="success"><?php echo $successMessage;?></span>
</form>
</div>
</div>
</body>
</html>

(2) write code for "validation.php" file :

<?php // Initialize variables to null.
$name =""; // Sender Name
$email =""; // Sender's email ID
$purpose =""; // Subject of mail
$message =""; // Sender's Message
$nameError ="";
$emailError ="";
$purposeError ="";
$messageError ="";
$successMessage =""; // On submitting form below function will execute.

function test_input($data)
{
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
if(isset($_POST['submit'])) { // Checking null values in message.
if (empty($_POST["name"])){
$nameError = "Name is required";
}
else
{
$name = test_input($_POST["name"]); // check name only contains letters and whitespace
if (!preg_match("/^[a-zA-Z ]*$/",$name))
{
$nameError = "Only letters and white space allowed";
}
} // Checking null values in the message.
if (empty($_POST["email"]))
{
$emailError = "Email is required";
}
else
{
$email = test_input($_POST["email"]);
} // Checking null values in message.
if (empty($_POST["purpose"]))
{
$purposeError = "Purpose is required";
}
else
{
$purpose = test_input($_POST["purpose"]);
} // Checking null values in message.
if (empty($_POST["message"]))
{
$messageError = "Message is required";
}
else
{
$message = test_input($_POST["message"]);
} // Checking null values in the message.
if( !($name=='') && !($email=='') && !($purpose=='') &&!($message=='') )
{ // Checking valid email.
if (preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/",$email))
{
$header= $name."<". $email .">";
$headers = "FormGet.com"; /* Let's prepare the message for the e-mail */
$msg = "Hello! $name Thank you...! For Contacting Us.
Name: $name
E-mail: $email
Purpose: $purpose
Message: $message

$msg1 = " $name Contacted Us. Here is some information about $name.

if(mail($email, $headers, $msg ) && mail("receiver_mail_id@xyz.com", $header, $msg1 ))
{
$successMessage = "Message sent successfully.......";
}
}
else
{ $emailError = "Invalid Email";
}
}
} // Function for filtering input values. function test_input($data)
