    <p>I was hoping someone might be able to help with this small issue I'm having with some code I'm working on. Please keep in mind, this is just for a hobby site, I am aware there are security holes. I have written a function called set_remember_cookies that is called from my login script and registration page when the user checks the "remember me" box. </p> <p>A function on each secured page then does the following:</p> <ol> <li>Checks to see if the remember cookies are set</li> <li>Queries the database to find the User_ID associated with the hashed username in the cookie</li> <li>Gets the password for that User_ID from the user table</li> <li>Gets the salt from the remember_cookies table</li> <li>Hashes the password + salt and matches it against the hashed password in the cookie </li> </ol> <p>Again, I know it is insecure to store even a hashed password in a cookie, but I am not worried about that now.</p> <p>My problem is that the set_remember_cookies function, that I have included below, is not actually setting the cookies. On the secured pages, the first step (checking if the cookies exist) fails. I have also checked in the browser for the cookies, and they are not stored. </p> <p>Can anyone explain to me why this function is not setting the cookies? I can't find any errors, but hopefully someone can! Thanks!</p> <pre><code> &lt;?php function set_remember_cookies($uid, $identifier, $password) { mysql_query("DELETE FROM remember_cookies WHERE User_ID = '$uid'"); //Delete old cookie records $salt = sha1(uniqid(time() . $_SERVER['HTTP_REFERER'])); $username_hash = hash("sha256", $identifier . $salt); //Hash the username if (mysql_query("INSERT INTO remember_cookies (User_ID, Username_Hash, Salt) VALUES ('$uid', '$username_hash', '$salt')")) { setcookie("Username", $username_hash, 60*60*24*365); setcookie("Password", hash("sha512", $password . $salt), 60*60*24*365); } } ?&gt; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
