Nowadays every website authenticating a user using some of the greatest trusty third party websites like Google, yahoo or some of the social networks. Today we are learning how to authenticate a user using his Yahoo account. By using third party login we make user feel happy by avoiding filling a registration form. So just start with a simple illustration.

The Basic work flow
Little Description
1. If user want to login with his yahoo account he is redirected to yahoo login page from our website for authentication.
2. After successful login yahoo issues user data along with his GUID (Globally Unique Identifier) to our website.
3. We are identifying a user using his GUID in our database. In third step we need to check our database for existence of GUID if it is present the user is old user and display his account. If GUID is not present insert a new record and allot new privileges for him by creating a new account.
4. Display user account with his data.
In order to start working with Yahoo SDK you need to register a web application and get the Application ID, Consumer keys.
1. Creating a new Application
a) Register a new application
b) Get the Application ID, Consumer Key and Consumer Secret.
After getting the Keys for your application next step is to Create a Table for the users.
2. Designing the Database
Create a table for the users with the fields uid, oauth_vendor, oauth_id, name
CREATE TABLE users(
uid INT(11) PRIMARY KEY AUTO_INCREMENT,
oauth_vendor VARCHAR(15),
oauth_id varchar(50),
name VARCHAR(30)
);
uid INT(11) PRIMARY KEY AUTO_INCREMENT,
oauth_vendor VARCHAR(15),
oauth_id varchar(50),
name VARCHAR(30)
);
3. User authentication and Storing User GUID
yahoo_connect.php

In Api after getting the Keys for your application check for SUB DIRECTORY option in the list provided below to your keys.
ReplyDeleteSelect the RADIO BUTTON Read/Write Public and Private inorder to get login page..
You won't be redirected to login page and will be in same page until you select this radui button and save the information.
After getting API Keys,
ReplyDeleteYou need to CHeck for SOCIAL DIRECTORY option below keys.
You need to check " Read/Write Public and Private" RADIO BUTTON.
You remain in the same page and won't be redirected to login page until u select this radio button and save the information.
It does not work in my site!

ReplyDeleteIt seems that if you arrive on yahoo registrayion / login page and click "Back" button, the next attempt to login with yahoo throws this error:
Warning: First parameter must either be an object or the name of an existing class in /home/hotpens/www/yahoo/Yahoo.inc on line 1372
Warning: First parameter must either be an object or the name of an existing class in /home/domain/www/yahoo/Yahoo.inc on line 1372
Warning: Cannot modify header information - headers already sent by (output started at /home/domain/www/yahoo/Yahoo.inc:1372) in /home/domain/www/yahoo/Yahoo.inc on line 343
Any idea on how can it be fixed? Also, it throws the same error if you use a linkedin script and not get logged in and after the yahoo one.
Thanks
