表单提交后刷新页面

Question

I have a button that extracts data to csv file. At the same time, after it extracts the table datas to csv file, it executes a query that TRUNCATES the data in the table. The thing is, the datas in that table is echoed in a . That's why I need to refresh the page so that the datas in the will reset.

I tried different things like:

onSubmit="window.location.reload()"
onClick="history.go(0)"

But it doesn't refresh the page. But when I use:

header('location:redirect.php');

It did refresh, but it doesn't extract the datas to csv file anymore. What seems to be the problem?

Answer 1

Put header("Location: index.php"); exit(); header("Location: index.php"); exit(); after the extraction of the CSV.
