How to Integrate login with LinkedIn oAuth in PHP
Now a days popular sites provide api so that we can integrate in our sites and get there information on one click no more fill complex forms etc. Today i am going to explain you how to integrate with LinkedIn one of the most popular website.
Follow new Tutorial: How to login with LinkedIn oAuth2 in PHP and MySQL
Make New Application on LinkedIn:
1.visit https://www.linkedin.com/secure/developer and click Add New Application.
Fill all information of your application.
You will get linkedin API key and Secret Key
Programming Time:
The script contains two folders called oAuth and images with PHP files.
oauth
– class.linkedClass.php // Class Get user Information
– config.php // Configuration file
– linkedinoAuth.php // Call methods
– OAuth.php // Twitter OAUTH library
images
linkedinauth.php //Call back page Show details
html.inc // html design view
index.php // Main index file show data
linkedin.php // Redirect to linkedin for authorization
PHP Code
Edit config.php
<?php $config['base_url'] = 'http://demo.phpgang.com/'; $config['callback_url'] = 'http://demo.phpgang.com/index.php'; //linkedin configuration $config['linkedin_access'] = 'your_linkedin_access'; $config['linkedin_secret'] = 'your_linkedin_secret'; $config['linkedin_library_path']= 'linkedinoAuth.php'; ?>
Index.php
Shows a button for linkedin authorization if not authorized.
Redirect you to linkedin.php generate token and redirect to linkedin app authorization page.
<?php
session_start();
include_once 'oAuth/config.php';
include_once 'oAuth/linkedinoAuth.php';
# First step is to initialize with your consumer key and secret. We'll use an out-of-band oauth_callback
$linkedin = new LinkedIn($config['linkedin_access'], $config['linkedin_secret'], $config['base_url'] . 'linkedin_login_oauth/linkedinauth.php' );
// $linkedin->debug = true;
# Now we retrieve a request token. It will be set as $linkedin->request_token
$linkedin->getRequestToken();
$_SESSION['requestToken'] = serialize($linkedin->request_token);
# With a request token in hand, we can generate an authorization URL, which we'll direct the user to
## echo "Authorization URL: " . $linkedin->generateAuthorizeUrl() . "\n\n";
header("Location: " . $linkedin->generateAuthorizeUrl());
?>
Once you Allow access it will redirect you on linkedinauth.php (defined in linkedin.php) and show all data of authorized user.

When you receive data you have to put you database queries there and insert data in database.
could you tell me where i can write the query in the given source code because i am not familiar with this auth integration.
https://www linkedin com/uas/oauth/authorize?oauth_token=
We were anable to find authorization token. How to fix this ?
If it is about hte server time and linkedin time sync problem, the how do we fix that ?
Change your server time to sync with linkedin.
How do we do that ? New to all this.
open linkedin.php
in the httpRequest function add:
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
I also changed ubuntu timezone to EST using follow command:
exec(“ln -sf /usr/share/zoneinfo/EST localtime”); // run this command in a new file and run on your server.
This erros should be fixed and linkedin should return request token.
Thanks a lot 😀
Can you tell me how can I store the data retrieved in a database ? I am able to store all elements except for skills field.
i am getting error “Notice: Use of undefined constant CONSUMER_SECRET – assumed ‘CONSUMER_SECRET’ in D:xampphtdocslinkedin_login_oauthindex.php on line 3” please suggest me way to solve this.

Debug error before redirecting to linkedin it might be time syncing error.
hello sir, i am also getting same error “An Error occurred during authorization, please try again later.” and url like “linkedincom/uas/oauth/authorize?oauth_token=”

Please see my reply above. This should solve your issue.
Looks like my comment has to be approved.. It was kinda lengthy with a photo attached.
After going a little further into the code – since I continued to get error messages. I noticed that in the same file (oAuth/linkedinoAuth.php) there were a couple of php errors that said a reference variable ‘debug’ was not set.
Change lines 57 & 73 to read if($this->debug), rather than just if($debug). For whatever reason, even though it was listed as a public variable at the beginning of the class, it wasn’t pulling through. This seems to have fixed this issue.
I think the wise choice for folks who are looking to use this is to store the token & secret that you receive from LinkedIn in a database of some kind or a session variable, because if you refresh the linkedinauth.php page after you’ve already logged in, it no longer has a trace of the token & secret – its only available the first time this page processes/loads and then you’ll have to go back to the log in page an do log in again. This causes two errors for unset variables ‘oauth_token’ & ‘oauth_token_secret’, which again would not be thrown if the script checked a DB or Session variable and if not set, redirect back to login page.
I also kept getting an error on line 121 in oAuth/linkedinoAuth.php – You have a comment listed as // Set the headers. Anything that I try and change this too, it kills the login and return of user information. I simply put the @ symbol in front of the line and kept it moving. Now it seems the script is working exactly as it should! 🙂
@huzoorbux:disqus you’re the man! Even though I’ve had to troubleshoot the code a bit, this is a great script!
You already have session variables! Awesome! 🙂
But in the linkedinauth.php file line 13 should read:
if (isset($_REQUEST[‘oauth_verifier’]) AND !isset($_SESSION[‘oauth_access_token’])){
rather than:
if (isset($_REQUEST[‘oauth_verifier’])){
Or it just tries to get another access token, but LinkedIn doesn’t like this and throws this error with the variable returned: [message] => [unauthorized]. The token used in the OAuth request is not valid.
Thank you @brandon_dewitt:disqus 🙂 you solved most of the issues
You’re very welcome 🙂
