Why does Javascript execution do not stop PHP execution?
I met a trouble with a script I have done.
Here is the entire script. But the trouble concern only 2 lines.
In fact I have a PHP condition if it is respected it should display an alert if not, it should execute the following script.
and at the end I have a header location that makes the user go back to the previous page.
The thing is that it does not display the alert, it directly make the user go back. I would like to make the user click on 'ok' in order to make the script continue. Is there a way I can do that.?

Javascript can't stop php execution! javascript runs on the client side (browser) and php runs in the server. if you write header('Location: ' . $_SERVER['HTTP_REFERER'] ); , it will always redirect you there.
If I was you, I would modify this line and add this:
echo "<script type=\"text/javascript\">alert(\"les interets sont deja a jour\"); window.location = $_SERVER['HTTP_REFERER']
</script>";
and remove the header location, of course..
