I'm providing a custom login page for the website visitors and would like to include the Login with Facebook button such that the application checks if the user email is registered, and if so it will log the user in.
using wp_signon I can log a user in by providing the email and password, but in that case I don't have a password for the user, so is there a way I can provide a Facebook login button without using plugins?
分享 Use this code and replace the APP ID with and your Domain...
<html>
<head>
<title>Login with Facebook</title>
</head>
<body>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'YOUR_APP_ID', // App ID
channelUrl : '//WWW.YOUR_DOMAIN.COM/channel.html', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
};
// Load the SDK Asynchronously
(function(d){
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
</script>
<div class="fb-login-button">Login with Facebook</div>
</body>
