    <p>If you know what the <code>datetime</code> value and the <code>username</code> values are then you can simply use:</p> <pre><code>SELECT * FROM orders WHERE username = '$username' AND datetime = '$datetime' </code></pre> <p>However, what you would be better off doing is splitting this into two separate tables; something like:</p> <pre><code>Orders OrderID OrderTime UserName Items ItemID OrderID Title </code></pre> <p>Then you would search in the following way:</p> <pre><code>SELECT Orders.OrderID, Orders.UserName, Items.Title FROM Orders INNER JOIN Items ON Orders.OrderID = Items.OrderID WHERE Orders.UserName = '$username' AND Orders.OrderDate = '$datetime' </code></pre> <p>When adding orders you add a record to <code>Orders</code> first, and then use that <code>OrderID</code> and add it to each item inserted in <code>Items</code>...</p> <h2>Insert Example</h2> <pre><code>$mysqli; //Assuming your connection to the database... $items; //Assuming an array of items for the order like: array('Coffee', 'Tea') $username; //Assuming the user name to be inserted for the order $mysqli-&gt;query("INSERT INTO Orders(`OrderTime`, `UserName`) VALUES(NOW(), '$username')"); $orderid = $mysqli-&gt;insert_id; foreach($items as $item){ $mysqli-&gt;query("INSERT INTO Items (`OrderID`, `Title`) VALUES($orderid, '$title')"); } </code></pre> <p><strong>NOTE:</strong> You should make sure to sanitize data before inserting to database...</p> <hr> <h2>Storing JSON</h2> <p>Storing <code>JSON</code> in a database is going to require you to make sure that you use a field data type that is an appropriate length (e.g. a <code>blob</code>).</p> <p>You mentioned that you retrieve the <code>titles</code> as an array from a form so I'm now going to refer to that as <code>$titles</code>.</p> <h3>Saving to database</h3> <pre><code>$username = '...'; // Username or id to store in database with order $titles = array(.....); // Array of titles from form $encodedTitles = json_encode($titles); // Convert to JSON $mysqli-&gt;query("INSERT INTO table_name (titles_field, username_field, date_field) VALUES ('$titles', '$username', NOW())"); // Save to database (assuming already open connection </code></pre> <h3>Retrieve from database</h3> <pre><code>$result = $mysqli-&gt;query("SELECT titles FROM table_name WHERE username = 'username_value' AND date_field = 'date_value'"); //Run query to get row $row = $result-&gt;fetch_assoc(); // Fetch row $titles = json_decode($row['titles']); // This is the same as the `titles` array from the from above! </code></pre>

    2. COin my php files I've declared products as array from where I get `title` via checkboxes and quantity via textboxes. Since I have to store array and mysql does not support this in tables, can I work with procedures for instance or am I wrong?

    3. COWhy do you need to store an `array`? Also, are we talking about your original code? or have you changed it?

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.
