My wife and I just had our first baby, which is the occassion for much nachas and, by extension, picture sharing. Facebook is, for better or for worse (emphasis on the latter), the de facto place for such sharing to happen. For a number of reasons – a desire to be somewhat selective about who sees my family pictures, my Project Reclaim sensibilities, the fact that I don’t have a Facebook account and generally think that Facebook is an evil company – I don’t want to use FB for this purpose. As in the case of my Twitpic-like photoblog, I figured I could use WordPress to set something up that was nearly as seamless as Facebook, or Google+, or Flickr, or whatever.
There were a few things I wanted out of the baby site.
- Easy (or zero) login for users
- Control over who has access
- Optional email notification for new content
When I started, I was pretty sure that I’d be able to get all of these things pretty easily, using existing WordPress plugins. I was both right and wrong about this: plugins exist for all of these purposes, but none of them were very easy to implement. As a result, I ended up building several pieces from scratch. I’ll go through each of the criteria, talk a bit more about what I was looking for, and then say something about how it was achieved. By doing this, and sharing the code (spoiler alert: https://github.com/boonebgorges/Hard-G/tree/master/wp-content), I’m hoping that I can help others with similar sensibilities to get started on their own sites.
Non-sucky registration and login
I love WordPress, and I understand the important reasoning behind the decisions that led to the design, but WP’s user registration system sucks. I didn’t want just anyone to be able to create and activate an account. I didn’t want users to have to click an activation link. I didn’t want users to have randomly generated passwords that would need changing later on. And I wanted users to have the option of logging in a non-WP way.
Several of these problems could be solved by using Facebook logins. I’m not willing to give my photos over to the horrific FB leviathan, but I’m happy to piggyback on their login APIs if it will save my family and friends a few headaches. I wanted my users to have the option of clicking a single button that would give my site the ability to provision them based on their persistent Facebook login.
So I boned up a bit on the FB API, and wrote a small plugin that I call Wally Login. Together with the registration page template from my custom theme (a child of TwentyEleven), it does a couple of key things.
- Rudimentary access control · If a non-logged-in user tries to visit any page on the site (other than the registration page), he is redirected to the Register page.
- FB login integration · If a user clicks the “Log me in using Facebook” link, they’re directed to the FB authorization page for my website (which is registered as a Facebook app). There, they’re asked to approve the app – a one-time process – and are then returned to my site. Based on the display name, email address, etc that I get from FB, I create a WP user corresponding to the FB account. On future visits, approved users who are logged into Facebook will be automatically logged into my WP site whenever they visit it (an important point, because FB cookies are persistent over browser sessions, while WP logins, by default, are not). As a result, in the best-case scenario, a user will authorize their FB account with my site one time, and will never again have to think about authorization on Wally’s page.
- A customized WP registration process · If users opt not to go the FB route, they can create a WP account directly on the site. I wanted to avoid sending users to an unthemed wp-login.php or wp-signup.php page, so I cribbed a few lines of code from BuddyPress and made my own registration and login dialogs. Wally’s site is part of a larger WP network, but I wanted to bypass WPMS’s built-in registration stuff (which requires users to activate their accounts, and is thus generally too hard for newbies to grok). My custom registration therefore creates the user directly (with
wp_insert_user()), using a password that he provides, and skips the activation email. (By bypassing account activation, I’m removing an important spam prevention tool. More on that in the next section.)
- Customized email notifications · Because I’m not using the built-in registration process, I needed to write my own email notifications for account applications and approvals.
If you decide to use my code, keep in mind that it’s not particulary beautiful. I wrote it for my own use, which means that it will take a bit of elbow grease to get it to work on your own site. In particular, if I were writing something for more general distribution, I would not be so reliant on a theme template as I am here. But if you’re looking to create a site like mine, this code is a great place to start – especially the FB integration stuff, which has made the registration and login process about as smooth as it can get.
The final important thing that the Wally Login plugin does is to provide me (the site admin) with control over who has access to the site. There are a couple ways I could have approached this issue. One is to whitelist users ahead of time. The problem with this is that I’m bound to forget some names, get email addresses wrong, and run into other problems that stem from my unfortunate lack of omniscience. Another strategy is the invitation code. When unique to the individual, this method suffers from the same drawbacks of the whitelist; when non-unique (ie when everyone uses the same invitation code) it takes away much of the security, as the code can be passed around quite easily; either way, invitation codes are clunky, easily misplaced, and all too often mistyped.
As a result, I ended up going with a third option: an application and approval process. Here’s the idea, conceptually. Anyone who wants can create an account on my site (either through Facebook or natively; see the previous section). However, the account does not actually allow access to the site unless the account is also approved by the administrators. Thus, after the initial application, two emails are sent: one to the applicant saying “thanks for applying, please be patient”, and one to me saying “there’s a new applicant, please approve them”. Then I go to my approval interface and click the Approve button (if I want), which marks the user as approved in my database and sends them an email saying “You’re in!”
Here’s a brief description of how it works technically. All applicants have a WP account created for them. Every new account is marked, at the time of creation, with user_status = ’2′, and I make sure that no page other than Register can be viewed by an account with user_status = ’2′. In this way, I am turning the idea of activation around a bit – natively, WP makes the user do the activation, but in my case I do it. The admin tool I use to activate users is my Unconfirmed plugin, designed for a slightly different purpose but quite at home here. (For technical reasons, Unconfirmed needs users to have activation keys; thus Wally Login also generates some dummy keys during the user creation process so that Unconfirmed will work right.) Unconfirmed, in turn, does the work of flipping user_status to 0 upon approval.
Taken together, Wally Login and Unconfirmed (with custom WP registration, FB integration, user approval by admin, etc) has given me a comfortable level of access control, without making the process unduly difficult for my users.
Email notification for new content
One of the biggest drawbacks of creating a standalone picture site instead of using an all-purpose social network (in practice, this means Facebook) is that the standalone site is likely to be forgotten. FB collects all of your network’s activity into a single stream; it’s highly unlikely, on the other hand, that Wally’s site will become part of anyone’s daily routine, so that they stop by to check for new content. For that reason, good email notification of new content is essential to making the site work.
I first tried using the popular Subscribe2 to handle these notifications. But I ran into a bunch of problems. For one thing, I didn’t like that S2′s subscription management happened in the Dashboard – I want to keep my users on the front end. S2′s category-based subscription is too complicated for my site, where people are either going to want to subscribe to all posts or to none at all. And the widget that comes with S2, for display on the front-end of the site, is pretty much atrocious. (Sorry. The rest of the plugin is nice. But that widget sucks.) At first I tried solving these problems just by building my own widget for S2, one that would tell the user whether he was currently subscribed, and show an Unsubscribe/Subscribe button, as appropriate. But, given the structure of S2′s data (which is somewhat arcane, and in any case far too complicated for my purposes), it ended up being a lot harder than it should have been.
So – wait for it – I wrote something from scratch. It is dead simple. Two parts: (1) a widget, which does exactly what I describe in the foregoing paragraph; and (2) hooks into publish_post to send an email to all subscribed users (along with some gentle checks to make sure dupes are not sent). This plugin has no admin UI and no options, because I don’t need any of those things.
Since the main point of the site would be to look at lots of pictures, it was quite important to have an easy, pretty way to do so. By “easy” I mean, primarily, navigable by keyboard; by “pretty”, I mean, primarily, bigger than the content area of a typical blog post. Less important, but still desirable, was the admin interface: I wanted it to be easy to upload lots of pictures at once, to add captions and other metadata if necessary, and to turn it all into a gallery that would look good on the front end.
You know the drill: I tried a couple of the more popular free plugins, but all of them were annoying in one way or another, and each one was way overengineered for my meager needs. I was especially disappointed by the back-end admin for the popular gallery plugins, which I found lugubrious, unintuitive, and impossible to extend. After some consideration, I decided that I actually preferred WP’s native Add Media interface for uploading photos and adding metadata, and that I was perfectly happy with the way that WP’s gallery shortcode displayed content on the front end, at least when viewing thumbnails.
I did make a few minor mods, though. First, the plugin is a bit greedy in the way that it filters the output of
get_attachment_link(), which was either breaking things (as in the case of comment_post_redirect on attachment posts) or making it hard to display links to the attachment page instead of the raw attachment file. The former problem I solved with a filter; for the latter problem, I was a bit lazy, so I modded the plugin itself in addition to adding an explicit ‘lightbox’ class to attachment links. This combination of hacks makes it work perfectly for my purposes.
Odds and ends
With my absolute requirements met, I was able to add a few other goodies to the site. My theme is a child of Twenty Eleven, which I’m pretty much using as-is. But I’ve added a few fun bits. First, on each attachment page, I added Download links, so that users could download images of various resolutions for printing or editing. I messed with the WP Admin Bar so that users coming from Facebook wouldn’t see Log Out and some other inappropriate links. And under each thumbnail in Gallery view, I’ve added Download/Comments links, so that users could bypass the jQuery lightbox and go straight to the attachment permalink if they wanted.
It took some work, but I think I’ve ended up with a site that is nice to use and easy to maintain, without resorting to the extreme discomfort associated with Facebook. Hooray!
