Body
Lately I've encountered problems using the admin area of my website. It seemed there were session problems. To see what's going on with <code>$_SESSION</code>, I've created the following script: <pre><code><? session_start(); mysql_connect("localhost", "USERNAME", "PASSWORD"); mysql_select_db("DATABASE_NAME"); if (isset($_SESSION)) { echo '<pre>session var: '; var_dump($_SESSION); $perm = mysql_fetch_assoc(mysql_query("SELECT * FROM `perm_groups` WHERE `id` = '".$_SESSION['perm']."'")); echo ' permission var: '; var_dump($perm); echo '</pre>'; } else { echo 'no session set'; } ?> </code></pre> $_SESSION['perm'] should contain a numeric string refering to the ID of the permission-group i have ("1" -> "admin") After login I call the script manually and get this result: <pre><code>session var: array(4) { ["user"]=> &string(17) "sebastian.philipp" ["auth"]=> &bool(true) ["perm"]=> &string(1) "1" ["llog"]=> &string(19) "2013-08-21 09:48:38" } permission var: array(7) { ["id"]=> string(1) "1" ["name"]=> string(4) "admin" ["create_pages"]=> string(1) "1" ["delete_pages"]=> string(1) "1" ["edit_pages"]=> string(1) "1" ["manage_users"]=> string(1) "1" ["manage_img"]=> string(1) "1" } </code></pre> When refreshing the page by pressing F5, it returns this result: <pre><code>session var: array(4) { ["user"]=> &string(17) "sebastian.philipp" ["auth"]=> &bool(true) ["perm"]=> &array(7) { ["id"]=> string(1) "1" ["name"]=> string(4) "admin" ["create_pages"]=> string(1) "1" ["delete_pages"]=> string(1) "1" ["edit_pages"]=> string(1) "1" ["manage_users"]=> string(1) "1" ["manage_img"]=> string(1) "1" } ["llog"]=> &string(19) "2013-08-21 09:48:38" } permission var: bool(false) </code></pre> And when refreshing again, it's like this: <pre><code>session var: array(4) { ["user"]=> &string(17) "sebastian.philipp" ["auth"]=> &bool(true) ["perm"]=> &bool(false) ["llog"]=> &string(19) "2013-08-21 09:48:38" } permission var: bool(false) </code></pre> So it semms like <code>$perm</code> gets written to <code>$_SESSION['perm']</code>, which shouldn't happen. What am I doing wrong?

1. COThe usual don't use mysql_* functions, seriously use mysqli_* database functions. Secondly, don't call `$perm = mysql_fetch_assoc(mysql_query(..))` in the same line. Save the result of the mysql_query to it's own variable, then use while loop to fetch the `mysql_fetch_assoc()` - Also, only need to run the Login once, add a trigger on the form, as using `isset( $_SESSION )` is quite inadequate.

2. COI didn't encounter problems with this before. And yes, you're right: session_start() creates the session var so it's not useful to check this. I should use isset($_SESSION['auth']) instead, shouldn't I?

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.
