How to ask for more permission after initial authentication in Facebook?

You need to send in the "extra" permissions the same way you got the initial ones. When your user hits the URL it will open up the same "permissions" box on FB that they were originally present with, but only with the new requested permissions set. They'll go through the same process of accepting or declining, then they'll come back to your site.

I've a facebook app at which I've asked users to give their email, work Info etc. The users have already granted the permission to retrieve these information. Now I want to retrieve their phone numbers also but I've not asked for it previously. So how do I ask the already authenticated users to give access to their phone numbers?

Is their some code which I can add and next time they logged in, they are prompted to authenticate that extra info? Facebook link|improve this question asked Jan 25 '11 at 15:27ptamzz1,220929 85% accept rate.

Edit: Make sure you add the same permissions you asked for originally, or FB will remove those original ones.

It doesn't work. Or am I missing something? I've put Login with Facebook – ptamzz Jan 25 '11 at 18:45 When you say it doesn't work, what do you mean?

Do you mean it's not sending the user to the Facebook site to ask for the additional permissions, or do you mean it's not adding the permissions? – El Guapo Jan 25 '11 at 18:50 The first time user has to authenticate, the facebook pop-up comes. Now I'd added the 'user_mobile_phone' in the perms and I was expecting that the next time the user tries to log in, he would be shown a similar pop-up with asking to allow to get the phone number just like the first time.

But the pop-up is not coming. – ptamzz Jan 29 '11 at 6:09 1 So, looking into it a bit, it looks like "user_mobile_phone" permission is temporarily disabled by FB. Try adding another just as a test to see if your implementation is working properly.

You can call FB. Login again but specify the permissions you want to request for this time with scope. Example below, where you are requesting publish_stream: FB.

Login(function() { if (response. AuthResponse) { // user gave permission } else { // user did not give permission } }, {scope:'publish_stream'}); You can also use FB. Ui with method set to 'permissions.

Request' See fbdevwiki.com/wiki/FB.ui#method:_.27perm....

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
