Redirect users to different locations after logging in and logging out.

== Description ==

Define a set of redirect rules for specific users, users with specific roles, users with specific capabilities, and a blanket rule for all other users. Also, set a redirect URL for post-registration. This is all managed in Settings > Login/logout redirects.

You can use the syntax **[variable]username[/variable]** in your URLs so that the system will build a dynamic URL upon each login, replacing that text with the user's username. In addition to username, there is "userslug", "homeurl", "siteurl", "postid-23", "http_referer" and you can also add your own custom URL "variables". See Other Notes / How to Extend for documentation.

You can add your own code logic before and between any of the plugin's normal redirect checks if needed. See Other Notes / How to Extend for documentation. Some examples include: redirecting the user based on their IP address; and redirect users to a special page on first login.

This plugin also includes a function `rul_register` that acts the same as the `wp_register` function you see in templates (typically producing the Register or Site Admin links in the sidebar), except that it will return the custom defined admin address. `rul_register` takes three parameters: the "before" code (by default "&lt;li&gt;"), the "after" code (by default "&lt;/li&gt;"), and whether to echo or return the result (default is `true` and thus echo).

== Installation ==

Installing this plugin is just like any other WordPress plugin.
Navigate to your WordPress “Plugins” page, inside of your WordPress dashboard, and follow these instructions:

1. In the search field enter **Peter’s Login Redirect**. Click "Search Plugins", or hit Enter.
1. Select **Peter’s Login Redirect** and click either "Details" or "Install Now".
1. Once installed, click "Activate".

== Frequently Asked Questions ==

Please visit the plugin page at http://www.theblog.ca/wplogin-redirect with any questions.

Login redirects not working? This plugin uses WordPress's standard login_redirect hook. The usual cause of problems is that another plugin is using the hook first, or there is a custom login form that isn't even running through the standard WordPress login functions.

== How to Extend ==

= Custom redirect rules =

You can write your own code logic before any of this plugin's checks for user-specific, role-specific, and capability-specific redirects, as well as before the fallback redirect URL.

An example of plugin code to redirect users on first login. See http://www.theblog.ca/wordpress-redirect-first-login for standalone functionality:

`// Send new users to a special page
function redirectOnFirstLogin( $custom_redirect_to, $redirect_to, $requested_redirect_to, $user )
{
    // URL to redirect to
    $redirect_url = 'http://yoursite.com/firstloginpage';
    // How many times to redirect the user
    $num_redirects = 1;
    // If implementing this on an existing site, this is here so that existing users don't suddenly get the "first login" treatment
    // On a new site, you might remove this setting and the associated check
    // Alternative approach: run a script to assign the "already redirected" property to all existing users
    // Alternative approach: use a date-based check so that all registered users before a certain date are ignored
    // 172800 seconds = 48 hours
    $message_period = 172800;

    /*
        Cookie-based solution: captures users who registered within the last n hours
        The reason to set it as "last n hours" is so that if a user clears their cookies or logs in with a different browser,
        they don't get this same redirect treatment long after they're already a registered user
    */
    /*

    $key_name = 'redirect_on_first_login_' . $user->ID;
    
    if( strtotime( $user->user_registered ) > ( time() - $message_period )
        && ( !isset( $_COOKIE[$key_name] ) || intval( $_COOKIE[$key_name] ) < $num_redirects )
      )
    {
        if( isset( $_COOKIE[$key_name] ) )
        {
            $num_redirects = intval( $_COOKIE[$key_name] ) + 1;
        }
        setcookie( $key_name, $num_redirects, time() + $message_period, COOKIEPATH, COOKIE_DOMAIN );
        return $redirect_url;
    }
    */
    /*
        User meta value-based solution, stored in the database
    */
    $key_name = 'redirect_on_first_login';
    // Third parameter ensures that the result is a string
    $current_redirect_value = get_user_meta( $user->ID, $key_name, true );
    if( strtotime( $user->user_registered ) > ( time() - $message_period )
        && ( '' == $current_redirect_value || intval( $current_redirect_value ) < $num_redirects )
      )
    {
        if( '' != $current_redirect_value )
        {
            $num_redirects = intval( $current_redirect_value ) + 1;
        }
        update_user_meta( $user->ID, $key_name, $num_redirects );
        return $redirect_url;
    }
    else
    {
        return $custom_redirect_to;
    }
}

add_filter( 'rul_before_user', 'redirectOnFirstLogin', 10, 4 );`

An example of plugin code to redirect to a specific URL for only a specific IP range as the first redirect check:

`function redirectByIP( $custom_redirect_to, $redirect_to, $requested_redirect_to, $user )
{
    $ip_check = '192.168.0';
    if( 0 === strpos( $_SERVER['REMOTE_ADDR'], $ip_check ) )
    {
        return '/secret_area';
    }
    else
    {
        return $custom_redirect_to;
    }
}

add_filter( 'rul_before_user', 'redirectByIP', 10, 4 );`

It takes 3 parameters:

* $custom_redirect_to: This is set as false in case you don't have any redirect URL to set. Return this instead of false in case you have multiple filters running.
* $requested_redirect_to: A redirect parameter set via POST or GET.
* $user: A PHP object representing the current user.

= Custom variable parameters =

There is an available filter "rul_replace_variable" for adding your own custom variable names. For example, to replace **[variable]month[/variable]** in the redirect URL with the numeric representation of the current month (with leading zeros):

`function customRULVariableMonth( $custom_redirect_to, $variable, $user )
{
    if( 'month' == $variable )
    {
        return date( 'm' );
    }
    else
    {
        return $custom_redirect_to;
    }
}

add_filter( 'rul_replace_variable', 'customRULVariableMonth', 10, 3 );`

Be sure to rawurlencode the returned variable if necessary.
