    <p>Below is my <strong>category.php</strong> that uses a switch statement to either show subcategories or products. When i click on a subcategory, it displays the products like it's supposed to. However, if the category has NO SUBCATEGORIES, no products will show at all.</p> <p>Is this a case where the <strong>switch statement needs to be altered</strong>, the entire <strong>foreach loop needs to be in an if statement</strong> or is there <strong>something wrong with the db</strong> and the ids... all of my cats in the menu have a parent_id = 0, subcats correspond to the id for the category table, the products are assigned a category_id. Is this a JOIN thing?</p> <pre><code>&lt;?php foreach ($listing as $key =&gt; $list){ echo "&lt;img src='".$list['thumbnail']."' border='0' align='left' /&gt;"; echo "&lt;h4&gt;"; switch($level){ case "1": echo anchor('welcome/cat/'.$list['id'],$list['name']); break; case "2": echo anchor('welcome/product/'.$list['id'],$list['name']); break; } echo "&lt;/h4&gt;"; echo "&lt;p&gt;".$list['shortdesc']."&lt;/p&gt;&lt;br style='clear:both'/&gt;"; } ?&gt; </code></pre> <p>Any help is much appreciated.</p> <p>the $level is located in the welcome controller.</p> <pre><code>function cat($id){ $cat = $this-&gt;MCats-&gt;getCategory($id); if (!count($cat)){ redirect('welcome/index','refresh'); } $data['title'] = "Company |" .$cat['name']; if ($cat['parentid'] &lt; 1){ // show other cats $data['listing'] = $this-&gt;MCats-&gt;getSubCategories($id); $data['level'] = 1; }else{ // show products $data['level'] = 2; $data['listing'] = $this-&gt;MCats-&gt;getProductsByCategory($id); } $data['category'] = $cat; $data['main'] = 'category'; $data['navlist'] = $this-&gt;MCats-&gt;getCategoriesNav(); $this-&gt;load-&gt;vars($data); $this-&gt;load-&gt;view('template'); } </code></pre> <p>get products by category function... This selects the products based on category_id in the products table. still no show though...</p> <pre><code> function getProductsByCategory($catid){ $data = array(); $this-&gt;db-&gt;select('id,name,shortdesc,thumbnail'); $this-&gt;db-&gt;where('category_id',$catid); $this-&gt;db-&gt;where('status','active'); $Q = $this-&gt;db-&gt;get('products'); if ($Q-&gt;num_rows() &gt; 0){ foreach ($Q-&gt;result_array() as $row){ $data[] = $row; } } $Q-&gt;free_result(); return $data; } </code></pre>

    1. COHow do you get `$level` variable? Don't see that in code.

    2. COOkei. Category doesn't have subcategories, but does it have products linked to it? Does your database design allow it?

    3. COyes i believe so... two tables categories products. categories has id, name, parent id. the sub cats are linked by parentid. products have category_id to link to each category but when i try set cat id to a cat rather than a sub cat no products show.

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.
