it seems like you are using wrong conditions for your loop instead of $i<$_SESSION['basket'] use $i<count($_SESSION['basket']) same problem for you if condition
count() gives the count of number of element in the array
Here is the fixed code
<?php
$broodjes_ID = $_GET['broodjes_ID'];
//onthouden van vorige get request
//$count = count($_SESSION['basket']); // count basket puts 3 times the same item in the shopping cart
//use count
if(count($_SESSION['basket']) > 0){
//use count
for($i = 0; $I<count($_SESSION['basket']); $i++){
//$basket = $_SESSION['basket'][$i];
$sql = "SELECT broodjes_ID, broodnaam, prijs FROM broodjes WHERE broodjes_ID = ?";
// uitvoeren, resultaat tonen in tabel.
$stmt = $conn->prepare($sql);
$stmt->bind_param("i", $broodjes_ID);
$stmt->execute();
$result = $stmt->get_result(); // get the mysqli result
//while loop zorgt er volgens mij voor dat hij blijft optellen
if($row = $result-> fetch_assoc()){
$sum = 0;
echo '<div class="cart-items">';
echo '<div class="cart-row">';
echo '<div class="cart-item cart-column">';
echo '<span class="cart-item-title">'. $row['broodnaam'] . '</span>';
echo '</div>';
echo '<span class="cart-price cart-column"> €'. $row['prijs'] . '</span>';
echo '</div>';
echo '</div>';
$sum = $row['prijs'];
break;
}
}
?>
