Hi, I am making a shopping cart and I have a problem. My code to remove the items from the cart works except for the first added item; I can delete all but that one.


This is the form to remove the items.

   

<form class="col-md-12" method="POST" action="" id="formremove">
                        <input type="hidden" name="id_prod" value="<?php echo $row['id_producto'] ?>">
                        <input type="submit" name="btn-remove" class="btn btn-info btn-sm" id="remove" value="X">
                      </form>

And this is the php

   

if ($_POST['btn-remove']) {
	  $id_user=$_SESSION['id_user'];
          $id_prod = $_POST['id_prod'];
          $SQLREM = "DELETE FROM `carrito` WHERE id_user='$id_user' and id_producto='$id_prod';";
          if (mysqli_query($conn, $SQLREM)) {
            echo '<script> alert("Ok"); window.location="/CBA/WAUW/cart.php"</script>';
          } else {
            echo '<script> alert("Error"); window.location="/CBA/WAUW/cart.php"</script>';
          };
        }

The connection to the database works fine; as I said before, it deletes everything but the first item added.

I would be very grateful for any help.

I would check that the query being executed is the one I think is being executed

if ($_POST['btn-remove']) {
	  $id_user=$_SESSION['id_user'];
      $id_prod = $_POST['id_prod'];
      $SQLREM = "DELETE FROM `carrito` WHERE id_user='$id_user' and id_producto='$id_prod';";

          echo $SQLREM;
          exit;
}

I tried that, and I realized that it seems that for that item (first added) the button does not work, it does not send the request for that item.... But I dont understand why, it works for the other items.
