Cookie questions

I am trying to get cookies working with a login page.

I have read a lot of tutorials on the net, but I just doesn't get all of it.

It seems that a rule is that you can't have any printable characters before setting a cookie. My question is then, what if you use templates for your site? (include()). Also, you have to use a form (html) for users to type their username/password before setting the cookie, so how is this done?

Also, if I want any scripts on my domain to be able to access the cookie, is it right to use '/' then? Example:

PHP Code:


setcookie("testcookie", "value", time() + (7 * 86400), '/', '.domain.com' );

Thanks in advance.

Yep that's right, no headers can come before setcookie() is called. If you want to use include() it depends on what the included file does. If it outputs characters then the script will fail.

What include() does is almost the same as writing the included content directly into your script.

To allow user login try the following:

PHP Code:


if ($HTTP_POST_VARS['submit_login'])

{

  // your code to check if logins are valid ( else die(); )



  setcookie(...); // set the cookie

  header("Location: $PHP_SELF"); // redirect to myself

  exit;

}



<html>

...

</html>

Note that freshly set cookies will not be available until the next page load.
