Force HTTPS 301 redirect with hook

Question

I am trying to force a 301 https redirect with hooking into the 'template redirect' function. I want not doing it a htaccess because when I update my permalinks, htaccess with https redirect disappears.

So with this function I want to do a redirect if the url is loaded with 'http', but nothing happens. Is there anyone who can help me with this?

add_action( 'template_redirect', 'bhww_ssl_template_redirect', 1 );
function bhww_ssl_template_redirect() {
    if ( is_ssl() && !is_admin() ) {
        if ( 0 === strpos( $_SERVER['REQUEST_URI'], 'http' ) ) {
            wp_redirect( preg_replace( '|^https://|', 'http://', $_SERVER['REQUEST_URI'] ), 301 );
            exit();
        } else {
            wp_redirect( 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'], 301 );
            exit();
        }
    }
}

We can add https in very simple way.... No need to had code all these in any hook....

1. Log in to wordpress admin
2. Go to Settings > General
3. Find WordPress Address (URL) and Replace HTTP with HTTPS
4. Find Site Address (URL) and Replace HTTP with HTTPS
5. Click Save Changes

Edit .htaccess file and add bellow code

RewriteEngine On
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} ^huepixel\.com$ [NC]
RewriteRule ^ https://www.huepixel.com%{REQUEST_URI} [L,R=301]

Install wordpress-https Plugin and configure it....

That's All
