Managing redirection after login and signup

Configure mod_signup to redirect to something other than a member’s home page.

Why

The default behavior of Zotonic is to redirect the user to his or her own page after logon (/page). If you want to change this, you need to modify the sitename.erl file, where sitename is the name of your site. Remember that this file is located in user/sites/sitename/.

Note

Your actual site location might be different, see the User sites directory.

Assumptions

Readers are assumed to be comfortable with Erlang syntax and use of the command shell.

How

Open user/sites/sitename/sitename.erl with your favorite editor:

$ cd /path/to/zotonic
$ vim user/sites/sitename/sitename.erl

Example 1

Redirection to the /welcome page after signup and to the /welcome-back page after logon

Add the following code:

-export([observe_signup_confirm_redirect/2, observe_logon_ready_page/2]).

%% @doc Set the page that must be opened after signup
observe_signup_confirm_redirect({signup_confirm_redirect, _UserID}, _Context) ->
    "/welcome".

%% @doc Set the page that must be open after login
observe_logon_ready_page({logon_ready_page, _}, _Context) ->
    "/welcome-back".

Example 2

Conditional redirection, where the site administrator is redirected to the /admin page, and all other users are redirected to the /welcome page:

-export([observe_logon_ready_page/2]).

%% @doc Set the page that must be opened after logon
observe_logon_ready_page({logon_ready_page, _}, Context) ->
    case z_acl:user(Context) of
        ?ACL_ADMIN_USER_ID  -> "/admin";
      _                   -> "/welcome"
  end.

Example 3

Conditional redirection with one option being the default behaviour:

-export([observe_logon_ready_page/2]).

%% @doc Set the page that must be opened after logon
observe_logon_ready_page({logon_ready_page, _}, Context) ->
    case z_acl:user(Context) of
        ?ACL_ADMIN_USER_ID  -> "/admin";
        _                   -> undefined     % All users except the administrator are redirected to their own pages
    end.

Example 4

Conditional redirection, where the site administrator is redirected to the /admin page and all other users are redirected to the /welcome page, unless another URL is specified:

-export([observe_logon_ready_page/2]).

%% @doc Set the page that must be opened after logon
observe_logon_ready_page({logon_ready_page, Url}, Context) ->
    case {z_acl:user(Context), Url} of
        {?ACL_ADMIN_USER_ID, _} ->
            "/admin";
        {_, []} ->
            "/welcome";
        _ ->
            Url
    end.

Save your changes and quit.

Recompile zotonic:

$ cd /path/to/zotonic
$ make

Now when logging in, you should see this redirect behaviour in action.
