    Hi,
    I have just started trying my hand at coding a WordPress plugin, I would like the plugin to hide posts in the category private from non-logged in users.

    I know the issue is with WP_Query and I have tried query_posts also, both with no luck. I’m sure i’m just making a noobie mistake but would appriciate a push in the right direction.

    This is what I have so far;

    /* to avoid name collisions check this function is not already defined. */
if (!function_exists("post_restrictor")) {

	/* Start of post restrictor function */
	function post_restrictor($content) {

	/* Get category ID for private */
	$cate = get_cat_id('private');

	/* retrieve posts without including the 'private' category. */
	global $contentResult;
	$contentResult = new WP_Query("cat=-$cate");

		/* loop current posts */
		if ( have_posts() ) : while ( have_posts() ) : the_post();

			/* check if post is in category private */
			if(in_category('private')) {

				/* check if user is logged in */
				if(is_user_logged_in()) {

					return $content;

				} else { // if user is not logged in return modified result.

					return $contentResult;

				}
			}
		endwhile;
		endif;

	} // end post_restrictor function

	/* add our filter function to the hook */
	add_filter('the_content', 'post_restrictor');

} // end name collision check

    forgive me if i’m way of track 😛

    This is my first attempt at a WordPress plugin so I really want to finish it.

    Thanks for any help you can give 🙂

    It appears as though you want to alter the content only if you are on a post in the ‘private’ category and the user is not logged in. Here is what I would recommend:

    add_action( 'init', 'my_init' );
function my_init() {
    if( in_category( 'private' ) && ! is_user_logged_in() ) {
        add_filter( 'the_content', 'post_restrictor' );
    }
}
function post_restrictor( $content ) {
    $content = "Sorry, you don't have access to this post.  Please login.";
    return $content;
}

    Thanks for the reply Micah, I have tried what you suggested but was unable to get it working.
    I have however managed to resolve it, this is how

    function exclude_category($query) {
	if(!is_user_logged_in()) {
		if ($query->is_main_query()) {
			$cate = get_cat_id('private');
        		$query->set( 'cat', '-'.$cate );
    		}
	}
}
add_action( 'pre_get_posts', 'exclude_category' );
