    <p>I have a hard time with isset() function. Exactly how do I tell php that only if the data was assigned to my, lets say $_SESSION['msg']; variable, only then activate it and use it... So far I am getting a lot of notices: undefined index and this code doesn't do it also: </p> <pre><code>if (isset($_SESSION['monster']) &amp; isset($_SESSION['spol']) &amp; isset($_SESSION['combat']) &amp; isset($_SESSION['turns']) &amp; isset($_SESSION['zmaga']) &amp; isset($_SESSION['zguba']) &amp; isset($_SESSION['cekini']) &amp; isset($_SESSION['post']) ) { $monster = $_SESSION['monster']; $spol = $_SESSION['spol']; $combat = $_SESSION['combat']; $turns = $_SESSION['turns']; $zmaga = $_SESSION['zmaga']; $zguba = $_SESSION['zguba']; $cekini = $_SESSION['cekini']; $_POST = $_SESSION['post']; } </code></pre> <p>Data was supposed to be asigned to it from a redirecting previous site but that site doesn't always activate so I need an alternative. That's why I am asking this.</p> <p>EDIT with full code:</p> <pre><code>session_start(); include 'razno.php'; include 'save.php'; include 'stats.php'; $igralec_ime = $_SESSION['username']; $monster = prikazi_borba($igralec_ime); $poskodbe = prikazi_stat('curhp', $igralec_ime); if (prikazi_stat('curhp', $igralec_ime) == 0) { $moznost = 'Tvoje zdravje je resno ogroženo, vrni se domov!'; } else if (isset($_SESSION['monster']) &amp;&amp; isset($_SESSION['spol']) &amp;&amp; isset($_SESSION['combat']) &amp;&amp; isset($_SESSION['turns']) &amp;&amp; isset($_SESSION['zmaga']) &amp;&amp; isset($_SESSION['zguba']) &amp;&amp; isset($_SESSION['cekini']) &amp;&amp; isset($_SESSION['post']) ) { $monster = $_SESSION['monster']; $spol = $_SESSION['spol']; $combat = $_SESSION['combat']; $turns = $_SESSION['turns']; $zmaga = $_SESSION['zmaga']; $zguba = $_SESSION['zguba']; $cekini = $_SESSION['cekini']; $_POST = $_SESSION['post']; } update_save($igralec_ime, 'gozd', $monster); include '../html/gozd.html'; ?&gt; </code></pre>

    1. COYou're using bitwise AND `&` instead of logical AND `&&`.

    2. COEasier still, you can use `if(isset($var1, $var2, $var3, ...))`, which will return `true` if all the variables are set.

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.
