    <p>I'm currently designing a shopping cart following a tutorial online.</p> <p>I have followed as much as I can down to each detail, with some changes such as variable names etc changing.</p> <p>I have checked through the code below, however when I clicked "Add To Cart" it doesn't display the added item in the side bar.</p> <p>Any suggestions as to what the issue may be? (The code is only the segment relating to the sidebar, the products php is in a separate php file.)</p> <pre><code>&lt;div id="sidebar"&gt; &lt;h1&gt;Cart&lt;/h1&gt; &lt;?php if(isset($_SESSION['cart'])){ $sql = "SELECT * FROM products WHERE SKU IN("; foreach($_SESSION['cart'] as $id =&gt; $value){ $sql .= $id. ","; } $sql = substr($sql,0,-1) . ") ORDER BY SKU ASC"; $query = mysql_query($sql); while($row = mysql_fetch_assoc($query)){ ?&gt; &lt;p&gt;&lt;?php echo $row['name']; ?&gt;&lt;?php echo $_SESSION['cart'][$row['SKU']]['quantity']; ?&gt;&lt;/p&gt; &lt;a href="index.php?page=cart"&gt;Go To Cart&lt;/a&gt; &lt;?php } }else { echo "&lt;p&gt;Your part is empty. &lt;br /&gt;Please add some products&lt;/p&gt;"; } ?&gt; &lt;/div&gt; </code></pre> <p>Section of code from products PHP file which does the adding:</p> <pre><code>&lt;?php if(isset($_GET['action']) &amp;&amp; $_GET['action'] == "add"){ $id = $_GET['id']; if(isset($_SESSION['cart'][$id])){ $_SESSION['cart'][$id]['quantity']++; } else { $sql2 = "SELECT * FROM products WHERE SKU=$id"; $query2 = mysql_query($sql2); if(mysql_num_rows($query2) != 0){ $row2 = mysql_fetch_array($qery2); $_SESSION['cart'][$row2['SKU']] = array("quantity" =&gt; 1, "price" =&gt; $row2['price']); } else { $message = "This product ID is invalid"; } } } ?&gt; </code></pre>

    1. COWhat precisely is your error? We need to know how you store the items in addition to how it is displayed

    2. COYour code only shows the reading section of your script. You are asking why a product isn't added to your cart (the "writing" section), so your code is useless for this question.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
