But the problem is, that my code is not working.</p> <p><strong>php</strong></p> <pre><code>&lt;?php session_start() ?&gt; &lt;?php if(isset($_POST['pid']) &amp;&amp; isset($_POST['length']) &amp;&amp; isset($_POST['Qty']) &amp;&amp; isset($_POST['Category'])){ $pid = $_POST['pid']; $length = $_POST["length"]; $qty = $_POST['Qty']; $Category = $_POST['Category']; **They are more codes below in this PHP tag which just check if the item the user is adding is already in the basket and if not it should add it.** } ?&gt; </code></pre> <p><strong>Adjust the Quantity of an item <em>(this is the code I am having the problem with)</em></strong></p> <pre><code> &lt;?php if (isset($_POST['item_to_adjust']) &amp;&amp; $_POST['item_to_adjust'] != "") { // execute some code $item_to_adjust = $_POST['item_to_adjust']; $quantity = $_POST['quantity']; $quantity = preg_replace('#[^0-9]#i', '', $quantity); // filter everything but numbers if ($quantity &gt;= 100) { $quantity = 99; } if ($quantity &lt; 1) { $quantity = 1; } if ($quantity == "") { $quantity = 1; } foreach ($_SESSION["cart_array"] as $array_key=&gt;$each_item) { if ($each_item['item_id'] == $item_to_adjust &amp;&amp; $each_item['length'] == $length &amp;&amp; $each_item['Category'] == $Category) { $_SESSION["cart_array"][$array_key]['quantity']+=$quantity; } } } ?&gt; </code></pre> <p><em><strong>HTML</em></strong></p> <pre><code>&lt;form action="check.php" method="post"&gt; &lt;input name="quantity" type="text" value="' . $each_item['quantity'] .

So I know that part of the code is working.</p> <p><strong>Issue</strong> I think it something to do with my <code>foreach</code> statement but I can't find it. I have try everything I know but I can't find anything.</p> <p>Please help me.</p>
