[SOLVED] how to use &&

[dadamssg]

i want to dress up my if statements. can anyone explain the correct use of &&? i want to do this

 

if($_SESSION['auth'] =="yes" && isset($_SESSION['logname']))
   {
        echo "<center><form action='reply_form.php?id={$postid}' method='POST'>
        <input type='submit' name='do' value='Reply'>
		</form></center>";
}

 

but this never shows my button...i want to show my button if auth=yes and that session variable is set

Check that $_SESSION['auth'] exists aswell

if(isset($_SESSION['logname'], $_SESSION['auth']) && $_SESSION['auth'] =="yes"))
   {
        echo "<center><form action='reply_form.php?id={$postid}' method='POST'>
        <input type='submit' name='do' value='Reply'>
         </form></center>";
}
// added for debug purposes only
else
{
    echo 'Problem! $_SESSION contains<pre>'.print_r($_SESSION, true).'</pre>';
}
