I am trying to show all the whiskies from my database with the dates alongside it , from the URL. I have several whiskies with the same names and want to show the price changes over the years. My current code is as below , but at the moment it is just showing one date , name and price. I am happy to show the one name at the top, but I would like to show all the prices and dates. if (isset($_GET['id'])) { $sql = "SELECT date , name , price FROM test_db WHERE name = :id ORDER BY name ASC"; $stmt = $conn->prepare($sql); $stmt->execute( [ 'id' => $_GET['id'] ] ); $row = $stmt->fetch(); echo "<div class='details'>"; echo "<br>"; echo $row['name']; echo "<br><br>"; echo $row ['date']; echo"<br><br>"; echo " £"; echo floor ($row ['price']); echo "<br>"; echo "<br>"; echo "<br>"; echo "</div>"; -
