This article explains how to upload a photo to Facebook with the Graph API, directly from a Canvas element. No server is needed, as in my recent article about Facebook upload with FormData.
Uploading a photo to Facebook is quite easy if the photo is on a server already. This tutorials explains how to upload a photo to Facebook directly from the device with FormData, without the need to upload in on a server first.
As a guy who prefers to use modern stuff like Node.js instead of crappy old PHP, I´m not really a fan of the Facebook PHP SDK. But sometimes you just need to use it – so here´s a basic tutorial for the current Facebook PHP SDK, they bumped it up a major version so i had to try it. It´s a bit weird that they call it “v4-5.0” though. I knew it would be a problem to use the tag “facebook-php-sdk-v4” on github…
Facebook changed their PHP SDK a lot with version 4.0, so i thought you could use a tiny tutorial how to authorize users and how to use the API with the new version. Feel free to comment about any errors or suggestions.
I´ve already explained how to use “Heroku” in my Article “Heroku – Gratis SSL für Facebook Apps“, but Heroku offers a lot more with the Add-Ons. For example, “PostgreSQL” for – surprise, surprise – PostgreSQL databases. A wonderful alternative to MySQL, to store User data in a Facebook App (for example). Here´s a mini-tutorial:
For Facebook Canvas Apps and Page/Tab Apps, you need a server with SSL. You can either buy a server with a certificate, or you can use the “Heroku Cloud Application Platform“. Up to 5MB space are for free, should be enough for smaller Apps. Just be warned, Heroku is pretty slow, it can take a few seconds until the Page responds.
This a follow-up of my recent article about reading the guest list of a Facebook Event created through Facebook Pages. If you want to get the Events (and the attendees) of a User, it´s a bit more work. You need to authorize the User with the permission “user_events”, and you will still just get the Events the user is attending too with the “/events” connection. I spare you the details of creating an app, this is just the authorization code for the PHP SDK:
$facebook->getLoginUrl(array('scope' => 'user_events'))
