I was told to stop using MySQL and now learning MySQLi. However I ran into a problem using fetch array and don't know what I did wrong. <pre><code>//Connect to db include "mysqli_connect.php"; // Construct our join query $sql = "SELECT userID, username, lastlogin FROM users"; //Crate results $result = mysqli_query($link, $sql); // Print out the contents of each row into a table $row = mysqli_fetch_array($result, MYSQLI_BOTH); // Free result set mysqli_free_result($result); // Close connection mysqli_close($link); </code></pre> <hr> Messages I see: <ul> <li>[Connection Successful] Host info: db413417616.db.1and1.com via TCP/IP</li> <li>Warning: mysqli_query() [function.mysqli-query]: Couldn't fetch mysqli in /homepages/9/d413002686/htdocs/maintenance/testsession.php on line 9</li> <li>Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, null given in /homepages/9/d413002686/htdocs/maintenance/testsession.php on line 12</li> <li>Warning: mysqli_free_result() expects parameter 1 to be mysqli_result, null given in /homepages/9/d413002686/htdocs/maintenance/testsession.php on line 15</li> <li>Warning: mysqli_close() [function.mysqli-close]: Couldn't fetch mysqli in /homepages/9/d413002686/htdocs/maintenance/testsession.php on line 18 ()</li> </ul> I used this to for mysqli_connect.php: <a href="http://www.php.net/manual/en/mysqli.construct.php" rel="nofollow">http://www.php.net/manual/en/mysqli.construct.php</a> <pre><code><?php // $link (host, username, password, database) $link = mysqli_connect('host', 'username', 'password', 'database'); //If connection is successful, otherwise show error message. if (!$link) { die('[Connect Fail] Error: (' . mysqli_connect_errno() .

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.
