The code is supposed to save a customers book order into a database, It works perfectly fine for ONE book. Line 76 to 81 has the insert statement. however if the person has purchased two books then only the last book gets added to the database. Screenshots added:
This is what it looks like on my website. As you can see the person has selected two books to be purchased: http://postimg.org/image/3kj1gvytx/ However this is what i get in my phpmyadmin site: http://postimg.org/image/k85hs56xj/ We can see that only the second book (biology) gets stored in the database. as well as the total of the two books
Any ideas how i could fix the issue and store both books.
Thanks

As you don't know Ajax, you can do something like this: 1) Reset $result array, to select items again for MySQL query. 2) With while loop insert each selected value into DB.
reset($result);
while($row=mysqli_fetch_array($result))
{
$ins = mysqli_query($con, "Here goes insert statement for each");
}
EDIT
$ISBN = $cart_itm["ISBN"];
$con = mysqli_connect("localhost","root","","yourbasename");
$result = mysqli_query($con, "SELECT Title,BookDesc, Price FROM books
WHERE ISBN='$ISBN'");
while($row=mysqli_fetch_array($result)
{
$insert = mysqli_query($con, "INSERT.....");
}
