How to implement Sign in with Twitter

Importance of implementing Sign in with Twitter

Getting the customer for your business website is important than anything. Researches states that sending the newsletter to the customer can make more leads. But it is hard to get the email of potential customers, or is it? Even if a website has a user sign up option, only a few of the visitors actually sign ups compared to the daily visits. It is seen that the users closes the website on seeing these long sign up forms. So we suggest you a way by which the customer finds it easier to give their details for you. By this method you get to collect the emails of the potential or interested users for your website. Now users  just need to click a button rather filling big forms. Twitter is of course a leading social media, implementing Sign in with Twitter also gets the user’s twitter profile. Following their tweets can also makes the newsletter sending more effective.

This is where the data of your customer will be stored. You get to have the email id of the signed in customers. These email id can be used in the future to send the newsletters. Code to create the table :

<!--?php require("twitter/twitteroauth.php"); require 'config/twconfig.php'; session_start(); &nbsp; $twitteroauth = new TwitterOAuth(YOUR_CONSUMER_KEY, YOUR_CONSUMER_SECRET); // Requesting authentication tokens, the parameter is the URL we will be redirected to $request_token = $twitteroauth--->getRequestToken('<a href="http://your-site.com/getTwitterData.php">http://your-site.com/getTwitterData.php</a>');
// Saving them into the session
$_SESSION['oauth_token'] = $request_token['oauth_token'];
$_SESSION['oauth_token_secret'] = $request_token['oauth_token_secret'];
// If everything goes well..
if ($twitteroauth->http_code == 200) {
// Let's generate the URL and redirect
$url = $twitteroauth->getAuthorizeURL($request_token['oauth_token']);
header('Location: ' . $url);
} else {
// It's a bad idea to kill the script, but we've got to know when there's an error.
die('Something wrong happened.');
