Здесь я должен обновить только category, sd, fd, assignto, reviewed и загрузить файл. Поэтому, когда пользователь нажимает кнопку обновления, он перейдет к update.php и обновит необходимые поля. Но его не выполняет и его показ предупреждения:PHP Update Query с использованием функции mysqli
Предупреждение: mysqli_stmt :: bind_param(): Количество переменных не соответствует числа параметров в подготовленном заявлении
Может кто-нибудь сказать мне, что не так?

«Количество переменных не совпадает». 'bind_param ('sssssb', $ category, $ sd, $ fd, $ assignto, $ review, $ upload);' имеет 7 параметров. Но в запросе 6. –
Теперь я прошел еще один параметр, но все еще не работал – Kiran
Можете ли вы также добавить структуру HTML-формы? – Cyberpks
