Facebook Login Button - Can I get Facebook to tell the user what info my app is getting?
Question
I used this guide from CodexWorld to create a facebook login button for my app https://www.codexworld.com/login-with-facebook-using-php/
It goes to a facebook login page that looks like this: http://puu.sh/xdxmv.png which is good, but we also want this page to show them what information Facebook is giving to our app. Looking for something like this: http://puu.sh/xdxy8.jpg . Is there a way do add that to this method of logging in?
The code that I think generates the button and tells it where to redirect:
$redirectURL = 'http://myapp.com'; // Callback URL
$fbPermissions = array('email'); // Optional permissions
$helper = $fb->getRedirectLoginHelper(); // Get redirect login helper
$loginURL = $helper->getLoginUrl($redirectURL, $fbPermissions); // Get login url
echo '<a href="'.htmlspecialchars($loginURL).'"><img style="margin-top: 10px;" src="assets/fblogin-btn.png"></a>'; // render the button
Thanks
