    <p>I've been reading about ajax in magento and their is alot of talk about modules and controllers, so after managing to setup a custom module, controller and frontend router i'm now having problems, at the moment i just want my ajax call to return an category page and its products depending on what id/param is posted to the controller. I dont know alot about PHP so i looked around and came cross this </p> <h1>The Controller</h1> <p> <pre><code>public function indexAction() { $id = $this-&gt;getRequest()-&gt;getParam('id'); if($id) { $_category = Mage::getModel('catalog/category')-&gt;load($id); $product = Mage::getModel('catalog/product'); //load the category's products as a collection $_productCollection = $product-&gt;getCollection() -&gt;addAttributeToSelect('*') -&gt;addCategoryFilter($_category) -&gt;load(); // build an array for conversion $json_products = array(); foreach ($_productCollection as $_product) { $_product-&gt;getData(); $json_products[] = array( 'name' =&gt; ''.$helper-&gt;htmlEscape($_product-&gt;getName()).'', 'url' =&gt; ''.$_product-&gt;getProductUrl().'', 'description' =&gt; ''.nl2br($_product-&gt;getShortDescription()).'', 'price' =&gt; ''.$_product-&gt;getFormatedPrice().''); } $data = json_encode($items); echo $data; } $this-&gt;loadLayout(array('helloworld_index_index')); $this-&gt;renderLayout(); } } </code></pre> <p>i know this is not exactly what i need but im having trouble coming to grips ajax in magento what i had in mind is that: </p> <ol> <li>in a ajax call i send the ID of the category to the controller</li> <li>the controller then arrays the products of the selected the category </li> <li>the array of products is sent/styled to the template file which is then sent back</li> </ol> <p>if anyone can please help me i would be truly greatful</p> <p>Thank you </p>

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.
