Я делаю проект, который должен иметь страницу поиска с PHP/MYSQL. На странице поиска есть ссылки для навигации для NEXT, LAST, PREVIOUS и FIRST, которые не работают. Когда я нажимаю NEXT или LAST, чтобы получить результаты на следующей странице, это дает мне ошибку «поисковый запрос не найден». Вот мой код:Pagination на странице поиска возвращает ошибку
<form name="search" method="post" action="search_ind.php">
