我希望此 PHP 代码重定向到上一页并自动刷新...我知道使用 JavaScript 我可以返回历史记录,但它不会刷新。请帮忙。
我的代码:
<?php
$con=mysqli_connect("host","user","pass","db_name");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
//post result to db
$result_set = mysqli_query($con,"SELECT points FROM total WHERE id = 1");
$row = mysqli_fetch_assoc($result_set);
$old_total = $row['points'];
$new_total = $old_total + $_REQUEST['total'];
mysqli_query($con,"UPDATE total SET points = $new_total WHERE id = 1");
mysqli_close($con);
?>
