PHP IF OR statement validation error

Im using the below code in order to add all Wordpress posts (excluding the 'sliders' category) to a category called 'Frontpage' ID = 28

function add_category_automatically1($post_ID) {
global $wpdb;
$postsWeWants = $wpdb->get_results("SELECT ID, post_author FROM $wpdb->posts where ID = $post_ID");
foreach ($postsWeWants as $postsWeWant) {
    if (!in_category('sliders'))  {
        $cat = array(28, );
        wp_set_object_terms($post_ID, $cat, 'category', true);
    }
}

I want to add the exception of an additional category called 'business-information' but I can't get the OR operator to validate properly.

I was looking at using something like below

function add_category_automatically1($post_ID) {
global $wpdb;
$postsWeWants = $wpdb->get_results("SELECT ID, post_author FROM $wpdb->posts where ID = $post_ID");
foreach ($postsWeWants as $postsWeWant) {
    if (!in_category('sliders')) OR (!in_category('business-information')) {
        $cat = array(28, );
        wp_set_object_terms($post_ID, $cat, 'category', true);
    }
}

You are using it wrong instead if (!in_category('sliders')) OR (!in_category('business-information')) {

write it like this (one more thing which is mentioned by @FirstOne you need to use AND instead OR to apply both conditions not one of them)

if( !in_category('sliders')  AND !in_category('business-information') ) {
...
}

so that both !in_category checks will be in same if( ... ) scops

This:

if (!in_category('sliders')) OR (!in_category('business-information'))
//                         ^ -- ^ -- and here

is wrong. Because you close ) and open ( too early. Proper code is:

if (!in_category('sliders') OR !in_category('business-information'))

And by the way such logic is invalid. If item is in 'business-information' then !in_category('sliders') true. I suppose you need to check for not existing in both cats:

if (!in_category('sliders') AND !in_category('business-information'))
