Move wp-signup.php functions to a wp-includes directory

[joemcgill]

Right now, all of the functions that deal with multisite registration are located in the wp-signup.php file, mixed in with control and template logic. This makes it difficult to reuse any of the registration functionality and makes it harder to create a custom registration experience for a network.

I'd propose moving all of the functional logic into a file in the wp-includes folder and include that file at the the beginning of the registration page, at minimum. Additionally, we could big and make wp-signup.php a dummy file and put everything into the wp-includes folder, as @markjaquith suggests in #31744. Even so, I think the functional logic should be separated out from the rest.

"makes it harder to create a custom registration experience for a network"

Im all in favour of a fix that will cure this issue. There needs to be an ability for each sub site to have a custom registration process.

Hi,

in 31928.diff, i've moved all wp-signup.php functions to wp-includes/ms-functions.php and wp-includes/ms-template.php. I also did the same with wp-activate.php.
I've created a new wp-includes/theme-compat/signup.php template to allow theme designers to use their own template and have this default one in case they don't.
I've also put the css rules into a css file: wp-includes/css/wp-signup.css.

Both files wp-signup.php and wp-activate.php are sharing this css file and the template.

I apologise if my function names are a bit exotic, i've try to do my best as i'm not so good at english.
