Introduce wp_registration_url()

[scribu]

It would be handy to have a wp_registration_url() template tag, to complete the wp_login_url() and wp_logout_url() triad.

$redirect param isn't useful

I noticed that wp-login.php itself never uses wp_login_url() so I didn't use wp_register_url() there either.

In 17950.2.diff​ since wp_register_url is filterable, we should probably esc_url when printing the register link. Also, you might want to remove the $redirect variable since it's undefined and we're not going to be using it anyway :)

[scribu]

Fixed in 17950.3.diff​ and also use it in wp-login.php.

Something to consider, wp_register_url() could easily be confused to provide functionality to register a URL like register_taxonomy() registers a taxonomy.

Suggestion: Change from verb to noun and call it wp_registration_url().

wp_registration_url()

[scribu]

Good idea!

[SergeyBiryukov]

We need a decision on the filter name.

17950.4.diff​ introduces register_url.

#14406 suggests reusing the same register filter we already have in wp_register():

I think 'register_url' is fine, because the 'register' hook contains the whole <a> tag.

I like wp_register_url() personally.

Replying to cartpauj:

I like wp_register_url() personally.

We have wp_login_url() and wp_logout_url() which are both using the noun form ("login" is the noun, "log in" is the verb). Hence why this is using the noun form.

Needs refresh after [23558]. @since 3.3.0 also needs to be updated.

[JustinSainton]

Refreshed.

[SergeyBiryukov]

There are 3 instances of site_url( 'wp-login.php?action=register', 'login' ) in wp-login.php (see [23558] for line numbers), I guess the third one needs to be replaced as well.

[JustinSainton]

Gotta catch 'em all, gotta catch 'em all.

[SergeyBiryukov]

With phpdoc corrections

[nacin]

In 24053:

Add wp_registration_url() and register_url filter.

props scribu, JustinSainton, SergeyBiryukov.
