Как добавить корзину?

<div class="blok">

<?php


$idcat = $_GET['idcat'];

$dbUser = 'root';

$dbName = 'shopp';

$dbPass = '';

$mysqli = new mysqli(' http://localhost/ ', $dbUser, $dbPass, $dbName);

$query = "set names utf8";

$mysqli->query($query);

$query="SELECT * FROM product WHERE id_category = '$idcat'";

$results = $mysqli->query($query);

while($row=$results->fetch_assoc()){


$tovars[] = array(

'id' => $row['id'],

'img' => $row['img'],

'name' => $row['name'],

'price' => $row['price'],

);

}


foreach ($tovars as $x){

echo '

<div class="tovar">

<a href="tt.php?id='.$x['id'].'"><img src='.$x['img'].'></a>

<div class="tovar-list">

<h3>'.$x["name"].'</h3>

<span class="price">'.$x["price"].'</span>

<a href="" class="button">В корзину</a>

</div>

</div>';
