Делаю POST jquery

ищет все новости по названию.
Хочу добавить

Код:

query: тест названия

Как сделать поиск новостей по номеру категории?

mSnus · 10 Янв 2019

перед

PHP:

//Отменяем новости с ненаступившей датой

дописать что-то вроде

Код:

if (isset($_POST['cat']) && $_POST['cat'] != "") {
  $cat_query  = $db->safesql(htmlspecialchars(trim($_POST['cat'])),ENT_QUOTES,$charset);
  $to_sql .= " AND category='".$cat_query ."'";
  $to_sql_chance .= " AND category='".$cat_query ."'";
}

Помогите понять как добавить фильтр вывода статей по номеру категории с базы MySQL?
