Обновить страницу после отправки формы

У меня небольшая проблема. Я хочу перезагрузить свою страницу после отправки формы.

сразу после ввода запроса перед> example

на вашей полной странице вы можете

Если вы хотите, чтобы форма была отправлена ​​на той же странице, удалите action из атрибутов формы.

Однако, если вы хотите перезагрузить страницу или перенаправить страницу после отправки формы из другого файла, вы вызываете эту функцию в php и она перенаправит страницу за 0 секунд. Кроме того, вы можете использовать header если хотите, просто убедитесь, что у вас нет содержимого перед использованием header

 function page_redirect($location) < echo ''; exit; > // I want the page to go to google. // page_redirect("http://www.google.com") 

атрибут действия в должен быть просто action=»»

Вам нужна форма, которая сама отправляет? Затем вы просто оставите параметр «действие» пустым.

Если вы хотите обработать форму на этой странице, убедитесь, что у вас есть какой-либо механизм в форме или данных сеанса, чтобы проверить, правильно ли они были отправлены, и убедиться, что вы не пытаетесь обработать пустую форму.

Возможно, вам понадобится другой механизм, чтобы решить, была ли форма заполнена и отправлена, но недействительна. Обычно я использую скрытое поле ввода, которое соответствует переменной сеанса, чтобы решить, щелкнул ли пользователь submit или просто загрузил страницу в первый раз. Каждый раз задавая уникальное значение и устанавливая данные сеанса на одно и то же значение, вы также можете избежать дублирования представлений, если пользователь дважды нажимает кнопку отправки.

 //insert this php code, at the end after your closing html tag. window.open('form.php','_self') "; // supposing form.php is where you have created this form > > //if statement close ?>
