php - ERR TOO MANY REDIRECTS - When redirecting user based on their selected city

one text

So I have a drop-down select that changes a custom field's value in their user profile based on their selected city. If a user chooses 'Detroit' for example, Detroit is then stored in their profile and that data is then used to redirect the customer based on their selection.

An issue I am running into seems to be if the customer selects a NEW different city on the homepage, or on a page deeper in the directory they get met with the TOO MANY REDIRECTS loop.

I understand WHY, I just can't seem to see where my issues are that are causing it.

Any help appreciated. Even if there is an easier, cleaner way to accomplish this.

        wp_get_current_user(); // wordpress global variable to fetch logged in user info
        $userID = $current_user->ID; // logged in user's ID
        $metalocation_display = get_user_meta($userID, 'location_select', true); // stores the value of logged in user's meta data for 'test'.

    if ( is_user_logged_in() && $metalocation_display == 'chicago' && strpos($url,'chicago') == false) {
