    <p>This php is suposed to send five attributes {id, description, email, price, shape} to the <em>sales</em> table in the <em>salesinformation</em> database.</p> <pre><code>&lt;?php define('DB_NAME', 'salesinformation'); define('DB_USER', 'root'); define('DB_PASSWORD', ''); define('DB_HOST', 'localhost'); $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD); if(!$link) { die('Cannot connect: ' . mysql_error()); } $db_selected = mysql_select_db(DB_NAME, $link); if(!$db_selected){ die('Cannot use ' . DB_NAME . ': ' . mysql_error()); } $value = $_POST['description']; $value2 = $_POST['email']; $value3 = $_POST['price']; $value4 = $_POST['shape']; $sql = mysql_query("INSERT INTO sales (id, description, email, price, shape) VALUES ('', '$value', '$value2', '$value3', '$value4')"); if (!mysql_query($sql)){ die('Error: ' . mysql_error()); } mysql_close(); ?&gt; </code></pre> <p>If I <code>echo $value</code> it prints out the correct information that I filled in my html form (So the part that extracts values from the HTML is working atleast). I run xampp and created the database with PhpMyAdmin, and when this PHP runs all I get is <em>Error: Query was empty</em> and nothing is added to the database at all. </p> <p>What makes the mysql_query empty?</p> <p>EDIT: I had missed a ' sign at one of the values. Now instead I get this error message</p> <pre><code>Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '1' at line 1 </code></pre>

    1. COSo you call `mysql_query`, then you call it once again passing something that's definitely not a query into it? Have you checked `http://php.net/mysql_query`?

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.
