PHP and MySQL: This should be so easy, but... I don't know how

susanv · February 25, 2011

I'm just learning php and I've created a test shopping website. Everything is working well, but I need help with the following:

This is my products table in the database:

"CREATE TABLE products (

id int(11) NOT NULL auto_increment,

product_name varchar(255) NOT NULL,

price varchar(16) NOT NULL,

details text NOT NULL,

category varchar(16) NOT NULL,

subcategory varchar(16) NOT NULL,

date_added date NOT NULL,

PRIMARY KEY (id),

UNIQUE KEY product_name (product_name)

) ";

I have 3 subcategories: Hats, Pants and Shirts.

On my index page I have links to these three items.

This is my products.php code. When run it shows all the items in the 3 subcategories. How do I change the code so that this page display only the Hats when someone clicks on the Hats link?

<?php

// Connect to the MySQL database

include "storescripts/connect_to_mysql.php";

$dynamicList = "";

$sql = mysql_query("SELECT * FROM products ORDER BY subcategory DESC");

$productCount = mysql_num_rows($sql); // count the output amount

if ($productCount > 0) {

while($row = mysql_fetch_array($sql)){

$id = $row["id"];

$product_name = $row["product_name"];

$price = $row["price"];

$date_added = strftime("%b %d, %Y", strtotime($row["date_added"]));

$dynamicList .= '<table width="100%" border="0" cellspacing="0" cellpadding="6">

<tr>

<td width="83%" valign="top">' . $product_name . '<br />

$' . $price . '<br />

<a href="product.php?id=' . $id . '">View Product Details</a></td>

</tr>

</table>';

}

} else {

$dynamicList = "We have no products listed in our store yet";

}

mysql_close();

?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<head>

<title>Store Home Page</title>

</head>

<body>

<?php include_once("template_header.php");?>

<tr>

<td width="35%" valign="top"><h3>Latest Designer Fashions</h3>

</p>

</p></td>

</tr>

</table>

</div>

<?php include_once("template_footer.php");?>

</div>

</body>

</html>

If someone can help me I'd be so grateful! :shrug:
