Trying to convert code to use arrays instead of MySQL database for items

n1concepts · January 15, 2011

I've been playing around with this code from http://v3.thewatchmakerproject.com/journal/276/building-a-simple-php-shopping-cart

Objective: I'm trying to make the scripts work but without pulling the data from MySQL Database.

Instead, I created an array and inserted some info there and trying to replicate the same results but getting confused.

For example, on the Index.php file, I made the following changes:

<?php

// Start the session
session_start();

// Include functions
require_once('inc/functions.inc.php');

// Products multidimensional Array
$products = array("book" => array(  'id' => '1',
                                    'title' => 'Learn Your ABC\'s',
                                    'author' => 'John Doe',
                                    'price' => '14.95'),
                    "video" => array('id' => '2',
                                    'title' => 'Visual Guide to learn',
                                    'author' => 'Adam Smith',
                                    'price' => '21.38'),
                    "puzzle" => array('id' => '3',
                                    'title' => 'Can You Solve?',
                                    'author' => 'Sara Brown',
                                    'price' => '9.41'),
                    "exam" => array('id' => '4',
                                    'title' => 'Test Your Knowledge',
                                    'author' => 'Kim Carver',
                                    'price' => '11.15'));

*/
?>

<?php
$output[] = '<ul>';
foreach ($products as $product => $product_item) {
// $flavor is the key and $piece is the value
foreach ($product_item as $item => $piece) {

    if ($item == "id") {                            # Conditional logic defined to map specific keys to specified name value
        $row['id'] = $piece;
//        echo "The id is ". $id."<br />";                            // set just to confirm value correct for variable
    }  elseif ($item == "title")  {                        # Conditional logic defined to map 1st key to price value
        $row['title'] = $piece;
//        echo "The title is ". $title."<br />";                            // set just to confirm value correct for variable
    }  elseif ($item == "author")  {                        # Conditional logic defined to map 1st key to price value
        $row['author'] = $piece;
//        echo "The author is ". $author."<br />";                            // set just to confirm value correct for variable
    }  elseif  ($item == "price")   {                    # Conditional logic defined to map 1st key to shipping value
        $row['price'] = $piece;
//        echo "Price: ". $price."<br /><br />";                        // set just to confirm value correct for variable
    }

$output[] = '<li>"'.$row['title'].'" by '.$row['author'].': $'.$row['price'].'<br /><a href="cart.php?action=add&id='.$row['id'].'">Add to cart</a></li>';
$output[] = '</ul>';
echo join('',$output);

}
}

?>
</div>

</body>
</html>

And here's the original index.php before my edits which show the sql query to the db:

<?php
// Include MySQL class
require_once('inc/mysql.class.php');
// Include database connection
require_once('inc/global.inc.php');
// Include functions
require_once('inc/functions.inc.php');
// Start the session
session_start();

<div id="shoppingcart">

<?php

?>

</div>

<div id="booklist">

<?php
$sql = 'SELECT * FROM books ORDER BY id';
$result = $db->query($sql);
$output[] = '<ul>';
while ($row = $result->fetch()) {
$output[] = '<li>"'.$row['title'].'" by '.$row['author'].': £'.$row['price'].'<br /><a href="cart.php?action=add&id='.$row['id'].'">Add to cart</a></li>';
}
$output[] = '</ul>';
echo join('',$output);
?>

</div>

</body>
</html>

Also, I included the zipped file of the entire script setup.

Again, I'm trying to figure out how to make the cart work with using an array for the product instead of MySQL database.

My goal is to remove ALL SQL statements from the scripts but stuck with the looping portion to display the title, author, and price from the array as shown above.
