Question

I'm working on a small catalogue which will take a list of products in a SQL database and list them on a catalogue.php page. When you click on a product, you'll be taken to a page with that specific product. So I have a productbuild.php which is the class that builds both the the catalogue and the individual product. The individual product is located at productview.php. I can view the products on the catalogue page but not on the productview page.

Here is my class:

require_once('connect.php');

        class Catalogue {   

            public $ksdb = '';


        public function __construct() {
            $this->ksdb = new Database;

            }
    //This function gets all the products on the main catalogue page, it works fine
            public function getProds() {
                $id = 0;
                //This is the prod array that is not being passed
                $prod = $return = array();
                $querystr = $this->ksdb->db_connect->prepare("SELECT * FROM products"); 
                try {
                    $querystr->execute();
                    for($i=0; $row = $querystr->fetch(); $i++) {
                        $return[$i] = array();
                        foreach($row as $rowi => $rowitem) {
                            $return[$i][$rowi] = $rowitem;

                        }
                    }
                } catch (PDOException $e) {
                    echo $e->getMessage();
                }
                return $return;
                //$prod = $return;
            }   



//This is the one that is not working on the productview.php page
            public function viewProd($prodID) {
                $prod = $return = array();
                $querystr = $this->ksdb->db_connect->prepare("SELECT * FROM products WHERE ID= ?");
                try {
                    $querystr->execute(array($id));
                    for ($i = 0; $row = $querystr->fetch(); $i++) {
                        $return[$i] = array();
                        foreach($row as $rowi => $rowitem) {
                            $return[$i][$rowi] = $rowitem;
                        }
                    }
                } catch(PDOException $e) {
                    echo $e->getMessage();
                }
                $prod = $return;
                $prod[0]['Description'] = $prod[0]['Description'];
                }
        }

And this is my productview.php page:

//Include the class
<?php include_once('/productbuild.php');

//Create an object of catalogue
$viewproduct = new Catalogue;


//if there is something in productview.php?ID= viewProd function is called
if(!empty($_GET['ID'])) {
    $prod = $viewproduct->viewProd($_GET['ID']);
    }
    else {
    echo "No Products";
    }

?>

//Echo the product name (from the DB) and Description
<h3><?php echo htmlspecialchars($prod['Name']); ?></h3>
  <?php echo htmlspecialchars($prod['Description']); ?>

Answer 1

How about changing your viewProd function from

$querystr->execute(array($id));

to

$querystr->execute(array($prodID))

Let me know if this solves your problem.
