Facebook在WordPress上的实现

Question

I'm using the new Instagram Graph API and would like to implement the 'Login via Facebook' inside the admin panel under settings so I can just authenticate my Business account to display media on the homepage.

Here is what I've done so far:

Inside facebook-jssdk.js: Has all the reference to the .js file that has to be included.

File path: /scripts/facebook-jssdk.js

// This is called with the results from from FB.getLoginStatus().
function statusChangeCallback(response) {
    console.log('statusChangeCallback');
    console.log(response);
    // The response object is returned with a status field that lets the
    // app know the current login status of the person.
    // Full docs on the response object can be found in the documentation
    // for FB.getLoginStatus().
    if (response.status === 'connected') {
        // Logged into your app and Facebook.
        testAPI();
    } else {
        // The person is not logged into your app or we are unable to tell.
        document.getElementById('status').innerHTML = 'Please log ' +
            'into this app.';
    }
}

// This function is called when someone finishes with the Login
// Button.  See the onlogin handler attached to it in the sample
// code below.
function checkLoginState() {
    FB.getLoginStatus(function(response) {
        statusChangeCallback(response);
    });
}

window.fbAsyncInit = function() {
    FB.init({
        appId      : '565176724011853',
        cookie     : true,  // enable cookies to allow the server to access
                            // the session
        xfbml      : true,  // parse social plugins on this page
        version    : 'v4.0' // The Graph API version to use for the call
    });

    // Now that we've initialized the JavaScript SDK, we call
    // FB.getLoginStatus().  This function gets the state of the
    // person visiting this page and can return one of three states to
    // the callback you provide.  They can be:
    //
    // 1. Logged into your app ('connected')
    // 2. Logged into Facebook, but not your app ('not_authorized')
    // 3. Not logged into Facebook and can't tell if they are logged into
    //    your app or not.
    //
    // These three cases are handled in the callback function.

    FB.getLoginStatus(function(response) {
        statusChangeCallback(response);
    });

};

// Load the SDK asynchronously
(function(d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0];
    if (d.getElementById(id)) return;
    js = d.createElement(s); js.id = id;
    js.src = "https://connect.facebook.net/en_US/sdk.js";
    fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));

// Here we run a very simple test of the Graph API after login is
// successful.  See statusChangeCallback() for when this call is made.
function testAPI() {
    console.log('Welcome! Fetching your information.... ');
    FB.api('/me', function(response) {
        console.log('Successful login for: ' + response.name);
        document.getElementById('status').innerHTML =
            'Thanks for logging in, ' + response.name + '!';
    });
}

The error that I am getting:

This is inside options-general.php - Do I have to have a fb reference somewhere?

All help would be appreciated!
