    <p>I am currently implementing a shopping cart using jQuery, Ajax and PHP and most of it is working. However I am currently stuck on how to update the main shopping basket page content when I update the cart as at the moment my returned html updates the shopping cart area in the sidebar (that works fine).</p> <p>So my question is how do I also update the table that displays all the shopping cart items in the main content area of the site at the same time?</p> <p>My jQuery (for updating the cart):</p> <pre><code>$('.update_cart').submit(function (e) { e.preventDefault(); $.ajax({ cache: false, url: 'inc/shopping_bag.php', data: $(this).serialize() + '&amp;action=update', type: 'POST', success: function(html) { $('#shopping-bag p').html(html); } }); }); </code></pre> <p>My PHP for updating:</p> <pre><code>elseif (!empty($action) &amp;&amp; $action == 'update') { if (is_array($_POST['item_qty'])) { foreach ($_POST['item_qty'] as $key=&gt;$quantity) { $quantity=ceil($quantity); if ($quantity==0) { unset($_SESSION['basket'][$key]); } else { $_SESSION['basket'][$key]['item_qty']=$quantity; } } } update_basket(); } function update_basket() { foreach ($_SESSION['basket'] as $array) { $totalItems+=$array['item_qty']; $cost=$array['item_qty']*$array['unit_price']; $total+=$cost; } echo 'Shopping Bag&lt;br&gt;'.$totalItems.' Items&lt;br /&gt;&amp;pound;'.sprintf("%01.2f", $total); } </code></pre> <p>My shopping cart page (sorry a bit long):</p> <pre><code>&lt;div id="content"&gt; &lt;section&gt; &lt;div class="content-seperator"&gt; &lt;h1&gt;Shopping Bag&lt;/h1&gt; &lt;/div&gt; &lt;div id="inner-content"&gt; &lt;section&gt; &lt;?php if (count($_SESSION['basket']) &gt; 0) { ?&gt; &lt;form action="#" class="update_cart"&gt; &lt;table id="cart"&gt; &lt;thead&gt; &lt;tr&gt; &lt;th width="60"&gt;Quantity&lt;/th&gt; &lt;th&gt;Item&lt;/th&gt; &lt;th width="70"&gt;Unit Price&lt;/th&gt; &lt;th width="60"&gt;Total&lt;/th&gt; &lt;th class="blank" width="90"&gt;&amp;nbsp;&lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tbody&gt; &lt;?php $total=0; $count=0; foreach ($_SESSION['basket'] as $array) { $check_id = substr($array['item_id'], 0, 5); $cost=sprintf("%01.2f", $array['item_qty']*$array['unit_price']); $total+=$cost; if (!empty($array['image'])) { if (file_exists($array['image'])) { $image_path = $array['image']; } else { $image_path = '&lt;img src="images/missing.gif" alt="missing image" /&gt;'; } } else { $image_path = '&lt;img src="images/missing.gif" alt="missing image" /&gt;'; } $image = getImagesize($image_path); $dimensions = imgResize($image[0], $image[1], 80); if ($check_id=='parts') { ?&gt; &lt;tr&gt; &lt;td class="align-centre"&gt; &lt;input name="item_qty[&lt;?php echo $count; ?&gt;]" type="text" size="1" value="&lt;?php echo $array['item_qty']; ?&gt;" class="formfield align-centre" /&gt; &lt;input name="unit_price[&lt;?php echo $count; ?&gt;]" type="hidden" value="&lt;?php echo $array['unit_price']; ?&gt;" /&gt; &lt;/td&gt; &lt;td&gt; &lt;span class="basket_img"&gt;&lt;img src="&lt;?php echo $image_path; ?&gt;" &lt;?php echo $dimensions; ?&gt; alt="Diesel Injector Image" /&gt;&lt;/span&gt; &lt;strong&gt;&lt;?php echo $array['category']; ?&gt; Injector&lt;/strong&gt;&lt;br /&gt; &lt;span class="basketlabel"&gt;Part No:&lt;/span&gt; &lt;strong&gt;&lt;?php echo $array['item_name']; ?&gt;&lt;/strong&gt; &lt;/td&gt; &lt;td&gt;&amp;pound;&lt;?php echo str_replace("£ ","",$array['unit_price']); ?&gt;&lt;/td&gt; &lt;td&gt;&lt;strong&gt;&amp;pound;&lt;?php echo $cost; ?&gt;&lt;/strong&gt;&lt;/td&gt; &lt;td&gt;&lt;a href="?removeItem=&lt;?php echo $array['item_id']; ?&gt;" class="basket_remove"&gt;Remove Item&lt;/a&gt;&lt;/td&gt; &lt;/tr&gt; &lt;?php } if ($check_id=='prods') { ?&gt; &lt;tr&gt; &lt;td class="align-centre"&gt; &lt;input name="item_qty[&lt;?php echo $count; ?&gt;]" type="text" size="1" value="&lt;?php echo $array['item_qty']; ?&gt;" class="formfield align-centre" /&gt; &lt;input name="unit_price[&lt;?php echo $count; ?&gt;]" type="hidden" value="&lt;?php echo $array['unit_price']; ?&gt;" /&gt; &lt;/td&gt; &lt;td&gt; &lt;span class="basket_img"&gt;&lt;img src="&lt;?php echo $image_path; ?&gt;" &lt;?php echo $dimensions; ?&gt; alt="Diesel Product Image" /&gt;&lt;/span&gt; &lt;strong&gt;&lt;?php echo $array['category']; ?&gt;&lt;/strong&gt;&lt;br /&gt; Product Code: &lt;strong&gt;&lt;?php echo $array['item_name']; ?&gt;&lt;/strong&gt; &lt;/td&gt; &lt;td&gt;&amp;pound;&lt;?php echo sprintf("%01.2f", $array['unit_price']); ?&gt;&lt;/td&gt; &lt;td&gt;&lt;strong&gt;&amp;pound;&lt;?php echo $cost; ?&gt;&lt;/strong&gt;&lt;/td&gt; &lt;td&gt;&lt;a href="?removeItem=&lt;?php echo $array['item_id']; ?&gt;" class="basket_remove"&gt;Remove Item&lt;/a&gt;&lt;/td&gt; &lt;/tr&gt; &lt;?php } $count++; } ?&gt; &lt;/tbody&gt; &lt;/table&gt; &lt;input type="submit" name="update_cart" value="Update Shopping Bag" class="rounded-buttons" /&gt; &lt;input type="button" name="empty_cart" value="Empty Shopping Bag" class="rounded-buttons" /&gt; &lt;/form&gt; &lt;?php } else { ?&gt; &lt;p class="no_items"&gt;You have no items in your shopping bag&lt;/p&gt; &lt;?php } ?&gt; &lt;/section&gt; &lt;/div&gt; </code></pre> <p>Any help greatly appreciated, thank you.</p>

    2. COSorry, you are right I should have been more specific. What I want to do is update the quantity and price of each product in the tabe if the quantities are changed and the 'Update Bag' is clicked or remove the row from the table if the item is removed. My problem isn't doing this as such but how to do this as well as update the shopping cart div in the sidebar as well.

    3. COUse JSON as response instead of HTML. So you would have something like: `response = [{ product: 'a', price: 1 },{ product: 'b', price: 2 },...]`, so you can re-use 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.
