How to Integrate Facebook login to WordPress?

Facebook API integration with a site improves your site’s social rank. We can integrate a like button to our website or a comment box which is quite easy. A bit messy job comes when we get a requirement to create an app for a website and then integrate it. There may be many reasons to create an app. May be you want to give the users to signup to your site using their Facebook account or you want to engage more traffic from your social circle to your site/blog using Facebook login.

So today we are going to sum up the tried and tested steps involved in integration of  Facebook login to WordPress manually without using any plugin. So let’s begin!

To integrate graph API to WordPress, we first need to create an app on Facebook using developer page. And then start it straight away.

Step 1:

Login to your Facebook account and go to developer page.

Click on add new app.

Step 6:

Please get back to your Facebook page and copy this code and paste it into your fb template file.  And you can see you have to give your site URL which in my case is localhost/wordpress. After putting your site URL click next.

So you have done a good job but as you know our objective is still not achieved.

Step 9:

If you go down of developer page you will see these boxes. Let’s integrate login to our site. Click on login box.

It will open a new tab and on that page you will find a complete code for login to put into your facebook template file.

Step 10:

After putting the code, just find this “{your-app-id}” and put your app id. You can get your app id by navigating to this page “My apps

Save your fb template and reload the page.

Ah, an error, but it was important to show you. See it is saying the URL is mismatching. But what is it about? Now go to “My apps” page and edit your app settings on edit settings page you will see the “App Domains” is empty and you should mentions your app domain over here. And we are using http://localhost/wordpress/facebook so our “App Domain” will be “localhost”. Put “localhost” in the box and click save. Now go to your WordPress page and reload it.

Awesome, now you can see something like this.

There are three things to take care of.

1: Which of the things you are taking from user.

2: User can edit and select which of the things he wants this app to access.

3: Facebook is assuring the user that this app will not put anything on your wall (Unless you give it permissions to do so).

After clicking OK, you will get a “response object” from Facebook. This object will have the whole detail. If you open your browser’s console you will see some sub objects of main object. You can console the whole “response object” to see the whole information it is carrying.

You can put the post request into this block or wherever you need. In our Test example, we are using TestAPI() function which fetches the user information from Facebook and shows you in console.log

"if (response.status === 'connected'){}"

You can make an ajax call at this point and store user information in your WordPress database and create Facebook login user as a WordPress user as well.  There should be part 2 of this tutorial which explains that how we make an ajax call and create Facebook login user as WordPress user as well. We will be sharing it soon seeing how much people are interested in it so looking forward to it, and you can ask anything related to integration of  Facebook login to WordPress in the comment box, will surely be helpful to all of our great readers!

  1. Great Tutorial i have been searching for one that properly explains the process for WordPress. I now have a working Facebook log in on my page

  2. Thanks for the great tutorial!

    I am having issues with Facebook app site url matching the page containing the code on a WordPress site. I have been able to get this to work on a simple index.html page that is hosted on heroku, however when I moved the code over to a WordPress site, I get this error:

    “Given URL is not allowed by the Application configuration: One or more of the given URLs is not allowed by the App’s settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App’s domains.”

    My site’s url is like this: http://mysite.com/test-home-page
    The url that I have in the FB Developer Portal -> Website -> Site URL is http://mysite.com/test-home-page

    I have tried putting mysite.com/test-home-page in the Site URL as well.

    Any ideas on this? Thanks in advance!
