Make Wordpress-blog totally private to logged out visitors?

I'm building a Wordpress-site, 开发者_如何学Cwhere user needs to log in before access to the blog itself. For now, I've used this:

add_action('wp_head','foofunc');
function foofunc() {
    if(!is_user_logged_in()) die();
}

However, this way I cannot redirect the user to another url, as output has already started. Is there any way to redirect not-logged-in users to an url?

I would user init but that redirects users in wp-admin too.

Use the "init" handler together with is_admin() to check if the user is already in the admin panel or not:

add_action('init','foofunc');
function foofunc() {
    $isLoginPage = strpos($_SERVER['REQUEST_URI'], "wp-login.php") !== false;   
    if(!is_user_logged_in() && !is_admin() &&  !$isLoginPage) {
        header( 'Location: http://yourdomain.com/login' ) ;
        die();
    }
}

This was a turnkey solution that worked right out of the box for us.

1. you could use the s2member plugin. It creates 4 user levels the first level is for free users. When you create a page, you can pick a S2Member userlevel requirement for that pages.
2. http://www.rlmseo.com/blog/require-login-for-wordpress-pages/ create a page-password-protect template that follows the format in that link. Apply the template to pages you want password protected.
3. you could write a function that checks to see if a user is logged in on pages using *is_user_logged_in()*, *is_admin()* and *is_page()* and then redirects. make that function an action. Then hook that action into init. (I'm a little fuzzy if init is the right hook, but your redirect won't happen if any output has been sent to the screen)

Cleanest implementation:

if( (!is_user_logged_in()) && ($GLOBALS['pagenow'] !== 'wp-login.php')  ) {
  wp_redirect('http://anothersite.com');
}

Can be placed as is in functions.php
