You have to realise that PHP code runs on the server, all before it sends the output to your browser. A basic example works like this: 1. You request a page in your browser by typing in the URL 2. The server receives this request 3. The server then does whatever processing is in the script (assuming you requested a .php file) and it is the script which is responsible for your HTML output 4. The web server sends this output back to your browser If you need things to be run on the server as a result of you doing something in your browser, then you need to either trigger some sort of page refresh or new page request, or use Javascript to make a series of AJAX requests. PHP code isn't run in your browser, and it knows nothing about what you do in it. For that, you need a client-side language such as Javascript. -- Thanks, Ash http://www.ashleysheridan.co.uk

Negin,
You cannot "pause" PHP. You need to do your checking and header() redirect on a
processing page that your form is submitting to.
file process
form.php Displays form
process.phpdecide what to you, redirect to secondary page
secondary.php display your secondary page

[PHP] i need delay time in doing array_key_exists but while(true) can't work 4 it.
===>if(array_key_exists('sub5',$_POST))
this line runs before i clicked on the submit
while(true) before this line can't work then how can i solve the time
problem?
here is the whole code:
0)
{
echo "";
for($i=0;$i<$num;$i++)
{
$row=mysql_fetch_row($result);
echo "";
for($j=0;$j<$num1;$j++)
{
echo"$row[$j]";
}
echo"";
echo"";
}
echo"";
}
}
if(array_key_exists('sub5',$_POST))
{
$_SESSION[s1]=$row[0];
header("Location: patient.php?");
}
?>
Doctor
