Codex tools: Log in
The "login_redirect" filter is used to change the location redirected to after logging in. This could be the location set by the "redirect_to" parameter sent to the login page.
A plugin can register a login_redirect filter with the code:
<?php add_filter( 'login_redirect', 'filter_function_name' ) ?>
Where 'filter_function_name' is the function WordPress should call during the login process. Note that filter_function_name should be unique function name. It cannot match any other function name already declared.
The filter passes 3 optional parameters
Note that the $current_user global may not be available at the time this filter is run. So you should use the $user global or the $user parameter passed to this filter.
You can register the login_redirect filter to use all 3 parameters like this:
<?php add_filter( 'login_redirect', 'filter_function_name', 10, 3 ) ?>
This example redirects admins to the dashboard and other users to the homepage. Make sure you use add_filter outside of is_admin(), since that function is not available when the filter is called.
function my_login_redirect( $redirect_to, $request, $user ){
//is there a user to check?
if( isset( $user->roles ) && is_array( $user->roles ) ) {
//check for admins
if( in_array( "administrator", $user->roles ) ) {
// redirect them to the default place
return $redirect_to;
} else {
return home_url();
}
}
else {
return $redirect_to;
}
}
add_filter("login_redirect", "my_login_redirect", 10, 3);
Redirect all logins to the homepage with an anonymous function (php 5.3+).
add_filter( 'login_redirect', create_function( '$url,$query,$user', 'return home_url();' ), 10, 3 );
