Question

以我的形式，

我根据输入从数据库中获取值，并在下拉列表中显示它。
现在，使用下拉列表中的选定值，我想使用预先分配的查询更新数据库。

到目前为止，我能够在下拉列表中获取数据。但是我无法使用所选值更新数据库。当我提交时，我没有看到任何错误，但数据库没有更新。我是PHP新手，不熟悉所有功能。这是下面的代码：

<?php

    $conn = oci_connect("XXX", "XX", "XX");
    if (!$conn)
    {
        $m = oci_error();
        echo $m['message'], "\n";
        exit;
    }

    $query = "SELECT ORDERS_ID,TRACKING_NUMBER
                FROM TABLE
                WHERE ORDERS_ID = :order_bv";
    $stid = oci_parse($conn, $query);
    if (isset($_POST['order']))
    {
        $order = $_POST['order'];
    }
    //$row = oci_fetch_array($stid, OCI_ASSOC);

    /* if (!$row) {
    //include ('error_page.php');
    exit("The order " . $order . " is invalid. Please check and try again" );
    } */


    oci_bind_by_name($stid, ':order_bv', $order);
    oci_execute($stid);


    if (isset($_POST['UpdateTR']))
    {
        $conn2 = oci_connect("XXX", "XX", "XX");
        if (!$conn2)
        {
            $m = oci_error();
            echo $m['message'], "\n";
            exit;
        }


        $query2 = "UPDATE TABLE
                     SET SHIP_TO_STR_DLVR_STATUS='Y'
                     WHERE TRACKING_NUMBER = :updTR_bv";
        $stid2 = oci_parse($conn2, $query2);
        $updTR = $_POST['updTR'];

        oci_bind_by_name($stid2, ':updTR_bv', $updTR);
        oci_execute($stid2, OCI_COMMIT_ON_SUCCESS);

        oci_free_statement($stid2); 
        oci_close($conn2);

    }
?>
