登录重定向在服务器上不起作用

Question

I developed a plugin for wordpress and I want to redirect different roles to different pages after login. I use below code and it works on my localhost (I use xamp) , but when I upload my plugin to server it doesn't work! and it just remain in "wp-login.php" after logining in and ofcourse the page goes white.

Code:

function loginRedirect( $redirect_to, $request, $user ){   
    global $user;
    if ( isset( $user->roles ) && is_array( $user->roles ) ) {
        //check for admins
        if ( in_array( 'administrator', $user->roles ) ) 
        {
            // redirect them to the default place
            return home_url()."/wp-admin/";
        } else if ( in_array( 'manager', $user->roles ) )
        {
           return  home_url()."/wp-admin/admin.php?page=creat_mysite_list_entry";             
        }
        else if ( in_array( 'jobholder', $user->roles ) )
        {
            if(have_contract_user($user->ID))
            {
                return home_url()."/wp-admin/admin.php?page=creat_mysite_register_entry";
            }
            else
            {
                return wp_logout_url();
            }
        }
    }                          
 }
add_filter("login_redirect", "loginRedirect", 10, 3);

You can try with ob_start() and ob_flush()

ob_start

goes top of the redirection and ob_flush goes end like this

ob_start();
header('Location:custompage.php');
ob_flush();
