For more information, see install an extension.

How to use

Enable the extension
Create a new Member section with only a email field (no password)
Set the required configuration values:

                
###### MEMBERS_FACEBOOK_LOGIN ######
'members_facebook_login' => array(
    'fb-app-id' => 'REPLACE ME',
    'fb-app-secret' => 'REPLACE ME',
),
########

Create a page and attach the Members: Facebook login event on it
Create the login form:

                
<form action="/facebook/" method="POST">
    <input type="hidden" name="redirect" value="/facebook/" />
    <input type="hidden" name="callback" value="/facebook/" />
    <input type="hidden" name="members-section-id" value="<Your section id>" />
    <input type="hidden" name="member-facebook-action[login]" value="Login" />
    <button>Log in with Facebook</button>
</form>

This form will redirect the user to facebook and then facebook will redirect the user to the ‘callback’ value.

Add another form to handle the actual log in process when the user comes back from facebook. This form can be auto-submitted

                
<xsl:if test="string-length(/data/params/url-code) != 0">
    <form id="facebookform" method="POST" action="{$current-url}/">
        <input type="hidden" name="code" value="{/data/params/url-code}" />
        <button>Validate</button>
    </form>
    <script>if (window.facebookform) facebookform.submit();</script>
</xsl:if>

If everything works, the user will be redirected to the ‘redirect’ value, just like the standard Members login.
