Login with LinkedIn

Linkedin Login API allows the user to sign into the website using their Linkedin account without sign up on that website. Here we can give an option to the user to register/ login to our system with their Linkedin Account. The process is like this: If the user click on "Login with Linkedin" button then it will ask Linkedin user name and password. If the user is using the system first time then it will fill up the registration form and display first name, last name, email and Gender fields. There will be no password field as the user is register / connect through Gmail. Once the user click on submit, our system will save the data in the server with the reference number sent by Linkedin. Next time when the user come and click on "Login with Linkedin" our system will check the reference number in our database, if it matches then it will sent the user directly to My Account page.
You can download the attached file and get the basic html form and other required files used in this project.

Click here to generate required Key for Linkedin.
Save the keys in config.php file.


define("CLIENT_ID", "************");
define("CLIENT_SECRET", "************");
define("REDIRECT_URI", "http://www.a2zwebhelp.com/demo/login_with_linkedin/");
define("SCOPE", 'r_basicprofile r_emailaddress' );

If the user registered before then our system will redirect the user to my account page otherwise it will ask the user to register for the first time.

$email	= $user->emailAddress;
$passcode	= $user->id;
$fname	= $user->firstName;
$lname	= $user->lastName;
$profilepic	= $user->pictureUrl;

/*Check if the user connected before */
$sql = db_query("select * from register_linkedin where passcode='".$passcode."'");
$numrow = mysqli_num_rows($sql);
if($numrow > 0){
	$_SESSION['email']	= $email;
	$_SESSION['passcode']	= $passcode;
