    copied!<p>I'm developing a website on my localhost which uses cookies. I have a function that generates a random, 25 character string which will be stored in a database and set as a referential cookie on the user's browser.</p> <p>I've searched the internet and this site, but wasn't able to find a solution for my problem.</p> <p>Below an overview of the related code</p> <pre><code> function generateRandomString($length){ $string = ""; $possible = "012346789abcdefghijklmnopqrstuvwABCDEFGHIJKLMNOPQRSTUVW"; $maxlength = strlen($possible); if($length &gt; $maxlength){ $length = $maxlength; } $i = 0; while($i &lt; $length){ $char = substr($possible, mt_rand(0, $maxlength-1), 1); if(!strstr($string, $char)){ $string .= $char; $i++; } } return $string; } $uCookie = generateRandomString(25); setcookie('uHash', $uCookie, time()+60*60*24*30); $stmt = $dbh->prepare(' UPDATE User SET u_UserCookie = :cookie WHERE u_UserId = :id '); $stmt->execute(array( ':cookie' => $uCookie, ':id' => $user_id )); </code></pre> <p>Now when i try <code>echo($_COOKIE['uHash']);</code> i get an empty string.</p> <p>The strange part is that when i check my chrome preferences, the cookie does exists</p> <pre><code>Name: uHash Content: 134uHnEPrCmBNGqeAjhRSUiJL Domain: localhost Path: /~path/to/login Send for: Any kind of connection Accessible to script: Yes Created: Wednesday, April 17, 2013 4:21:27 PM Expires: Friday, May 17, 2013 4:21:27 PM</code></pre> <p>The string '134uHnEPrCmBNGqeAjhRSUiJL' can also be found in the database, so that works</p> <p>Am i missing some basic info about cookies (on a localhost)?</p> <p><strong>SOLVED</strong></p> <p>The problem is, according to php.net <blockquote>'that domain names must contain at least two dots (.), hence 'localhost' is invalid and the browser will refuse to set the cookie'</blockquote></p> <p>So i solved it by doing this</p> <pre><code> $domain = ($_SERVER['HTTP_HOST'] != 'localhost') ? $_SERVER['HTTP_HOST'] : false; setcookie('uHash', $uCookie, time()+60*60*24*30, '/', $domain, false);</code></pre>
