Question

When button pressed:

<form action="index.php" method="get">
  <input type="hidden" name="act" value="run">
  <input type="submit" value="Truncate map">
</form>

if (!empty($_GET['act'])) {
  mysql_query("TRUNCATE TABLE mapinfo");
} 

It redirects me to index.php?act=run

I want to get rid of it so added: header("Refresh: 0; url=$page");:

if (!empty($_GET['act'])) {
  mysql_query("TRUNCATE TABLE mapinfo");
  $page = $_SERVER['PHP_SELF'];
  header("Refresh: 0; url=$page");
} 

but it first loads index.php?act=run than redirecting browser to index.php which makes 2 page refreshes.

How to do it the nice way?

Answer 1

instead of using a refresh header, use

header("Location: $page");
