i’m trying to get user info from facebook when a user tries to login through facebook on my website ,Wordpress website, I have been struggling to retrieve users’ birthday, email, first name, last name and interests and so on what is the code to get them. I’m newly to facebook apps so I don’t know what to do and what is the procedure

All what i can retrieve is the email, name and create username according to the url user name

some clear code would be useful Thank you

This is my code location in my directory:
wp-content/themes/themeName/framework/functions/facebook_login.php

<?php

function fb_head(){
  if( is_user_logged_in()) return;
  ?>

  <div id="fb-root"></div>
	<script>
		// Additional JS functions here
		window.fbAsyncInit = function() {
			FB.init({
				appId      : '<?php echo sq_option('fb_app_id'); ?>', // App ID
				version    : 'v2.0',
				status     : true, // check login status
				cookie     : true, // enable cookies to allow the server to access the session
				xfbml      : true,  // parse XFBML
				oauth      : true
			});

			// Additional init code here

		};

		// 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/sdk.js";
			 ref.parentNode.insertBefore(js, ref);
		 }(document));
	</script>
    <?php
}
add_action( 'kleo_after_body', 'fb_head' );

function fb_footer(){
?>

	var ajaxurl = '<?php echo admin_url('admin-ajax.php'); ?>';
	jQuery('.facebook_connect').click(function(){
			var context = jQuery(this).closest("form");
			if (jQuery(".tos_register", context).length > 0)
			{
				if (! jQuery(".tos_register", context).is(":checked"))
				{
					alert('<?php echo apply_filters('kleo_fb_tos_alert',__("You must agree with the terms and conditions.",'kleo_framework'));?>');
					return false;
				}
			}		
			
		FB.login(function(FB_response){
			if( FB_response.status === 'connected' ){
				fb_intialize(FB_response);
			}
		},
		{scope: 'public_profile,email'});
	});
