Question

I have the following code:

<?PHP

  if (isset($_POST['submit'])) {
    header("Location: http://mysite.com");
  }

?>

<form name="form1" action="" method="post"> 
  Name: <input name="name" type="text"> 
  <input type="submit" value="submit" name="submit">
</form>

The problem is that when I submit the form the redirection to mysite.com takes too long time, 5-10s.
I would like to display a messege “Loading… Please wait” och show an animated image so that I know that something is happening.

How do I do in javascript och ajax?

I don’t know if it’s possible (but I don’t think so) but you could add exit(); after setting the header so the rest of the script isn’t executed and sent to the browser. That could reduce the time a bit.

What you could try is to do the redirection with javascript instead of a http header.

<?php if (isset($_POST['submit'])): ?>
<script>
  alert('Loading... Please wait');
  document.location.href = 'http://mysite.com';
</script>
<?php endif; ?>
