    <p>Im trying to display two list: one for categories and brand but only the categories are being displayed. And when I remove the code for categories, the brands are being displayed. Is it because it is not possible to create instances of two classes in the same php page? In index.php:</p> <pre><code> &lt;?php $obj = new CategoryList(); if (method_exists($obj, 'init')) { $obj-&gt;init(); } for($i = 0;$i&lt; count($obj-&gt;mCategory); $i++) { echo "&lt;a href=''&gt;"; echo $obj-&gt;mCategory[$i]['name']. "&lt;br/&gt;"; echo "&lt;/a&gt;"; } $obj2 = new BrandList(); if (method_exists($obj2, 'init')) { $obj2-&gt;init(); } for($i = 0;$i&lt; count($obj2-&gt;mBrand);$i++) { echo "&lt;a href=''&gt;"; echo $obj2-&gt;mBrand[$i]['name']. "&lt;br/&gt;"; echo "&lt;/a&gt;"; } ?&gt; </code></pre> <p>Here's the code for the classes:</p> $mSelectedCategory = (int)$_GET['category_id']; } public function init() { $this->mCategory = Catalog::GetCategory(); } } ?> <pre><code>&lt;?php class BrandList { public $mSelectedBrand = 0; public $mBrand; public function __construct() { if (isset ($_GET['brand_id'])) $this-&gt;$mSelectedBrand = (int)$_GET['brand_id']; } public function init() { $this-&gt;mBrand = Catalog::GetBrand(); } } ?&gt; </code></pre> <p>Maybe this might help:</p> <pre><code>class Catalog { //get id and name of category public static function GetCategory() { $sql = 'CALL catalog_get_category_list()'; return DatabaseHandler::GetAll($sql); } public static function GetBrand() { $sql = 'CALL catalog_get_brands_list()'; return DatabaseHandler::GetAll($sql); } } </code></pre> <p>in DatabaseHandler class:</p> <pre><code> public static function GetAll($sqlQuery, $params = null, $fetchStyle = PDO::FETCH_ASSOC) { $result = null; try { $database_handler = self::GetHandler(); $statement_handler = $database_handler-&gt;prepare($sqlQuery); $statement_handler-&gt;execute($params); $result = $statement_handler-&gt;fetchAll($fetchStyle); } catch(PDOException $e) { self::Close(); trigger_error($e-&gt;getMessage(), E_USER_ERROR); } return $result; } </code></pre>

    1. COIf you're checking on the browser, look at the HTML source to see if the brands are actually being printed or not. If not, either your BrandList object is not being populated with entries, or there's an error, probably in the constructor or init() function.

    3. CO`$this->$mSelectedBrand` - one $ too much, `$this->mSelectedBrand`. Did you redact the code for Stackoverflow or is this really an error?

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.
