    <p>I am trying to remove an item from the basket using a 'delete' link. Currently, when the link is clicked, it isnt doing anything. If possible, could somebody steer me in the right direction please. I have a loop of each item in the order where $item will be the current item and $key is the index of the array.</p> <p>I then use html to output the items. Within this section I have a delete link:</p> <pre><code>&lt;td&gt;&lt;a href="processorder.php?delete=&lt;?=$key?&gt;"&gt;Delete&lt;/a&gt;&lt;/td&gt; </code></pre> <p>I also have the process of this:</p> <pre><code>if (isset($_GET['delete']) &amp;&amp; $_GET['delete']) { $key = $_GET['delete']; unset($_SESSION['order'][$key]); } </code></pre> <p>Below is all of the code for reference:</p> <pre><code>&lt;?php // start the session handler require_once('dbfunction.php'); //connect to database $conn = DB(); require_once('header.php'); if (isset($_GET['delete']) &amp;&amp; $_GET['delete']) { $key = $_GET['delete']; unset($_SESSION['order'][$key]); } //first of all, get this items information $query = "SELECT * FROM ".$tablename." WHERE ".$key." = '".$item['prod_id']."'"; $sql = mysql_query($query, $conn); $product = mysql_fetch_assoc($sql); //html for this product $grand_total = isset($grand_total) ? $grand_total : 0; $line_cost = $product['price'] * $item['quantity']; $grand_total += $line_cost; ?&gt; &lt;tr&gt; &lt;td&gt;&lt;?=$product['common_name'];?&gt;&lt;/td&gt; &lt;td&gt;&lt;?=$item['prod_type'];?&gt;&lt;/td&gt; &lt;td&gt;&lt;?=$product['price'];?&gt;&lt;/td&gt; &lt;td&gt;&lt;input type='text' name='quantity[]' value='&lt;?=$item['quantity'];?&gt;' size='2' /&gt;&lt;/td&gt; &lt;td&gt;&amp;pound;&lt;?=number_format($line_cost, 2);?&gt;&lt;/td&gt; &lt;td&gt;&lt;a href="processorder.php?delete=&lt;?=$key?&gt;"&gt;Delete&lt;/a&gt;&lt;/td&gt; &lt;/tr&gt; &lt;?php } ?&gt; </code></pre>

    1. COHave you examined the state of `$_SESSION['order']` before and after the delete clause? Use `print_r()` to do so.

    2. COBtw, you don't seem to be sanitising `$key` - and hence you have a SQL injection vulnerability in your `SELECT`.

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.
