Question

In an HTML page:

<a href="/files/getfile.php?name=abc.zip">file download</a>

in PHP script(getfile.php):

if('notlogged')
{
  echo 'please, loggin~'; //pop up, possible?
  return false;
}

So my question is, When user click the anchor tag, can I pop up a login window if user didn’t log?

I knew I can pre-check in Javascript before calling the PHP script whether user logged or not.

But, it’s not my case for use; the PHP script should have to throw pop up code.

The page user is viewing should not changed — just pop up login window.

Answer 1

The PHP script is executed on the server site, so it cannot generate a popup window when the link is clicked. You can accomplish your goal one of two ways:

1. Use Javascript to generate an AJAX call to your PHP script, and popup a login window as necessary.

2. Use header( “Location: /your/login/script.php” ) in getfile.php to send the user to a login page, but with no popup.
