Question

我在表格中添加了一个外键。现在，当我尝试将表单中的数据插入数据库时，它不起作用。我认为问题可能出在名为＆＃39; register_id＆＃39;的外键上。如何解决这个问题？

我的代码：

    <?php
$username = "root";
$password = "";
$hostname = "localhost";

$dbhandle = mysql_connect($hostname, $username, $password) or die("cannot connect to database");
$selected = mysql_select_db("audit", $dbhandle);
$strQuery = 'SELECT * FROM schedule';
$retval = mysql_query($strQuery, $dbhandle);
if (!$retval) {
    die('Could not get data: ' . mysql_error());
}

//insert code

if (isset($_POST['schedule'])) {
    //$id = ($_POST['id']);
    $_SESSION['company_session'] = $_POST['company_name'];
    $_SESSION['auditor_session'] = $_POST['auditor_name'];
    $_SESSION['date_session'] = $_POST['audit_date'];
    $_SESSION['time_session'] = $_POST['audit_time'];
    $_SESSION['status_session'] = $_POST['audit_status'];

    $company_session = $_SESSION['company_session'];
    $auditor_session = $_SESSION['auditor_session'];
    $date_session = $_POST['audit_date'];
    $time_session = $_POST['audit_time'];
    $status_session = $_SESSION['status_session'];

    mysql_query("INSERT INTO schedule (company_name,auditor_name,audit_date,audit_time,audit_status) VALUES ('$company_session','$auditor_session','$date_session','$time_session','$status_session')");
    //echo ("New Process Created successfully");
    header('Location: ?');
}
?>

// html代码

  <div class="form-group"><br>
                                        <table class="table">

                                            <tr><input class="form-control" type="hidden" name="id"></tr>
                                            <tr><input class="form-control" type="hidden" name="register_id"></tr>
                                            <?php
                                            $connect = mysql_connect("localhost", "root", "") or die("Could not connect to the database");
                                            mysql_select_db("audit") or die("could not find db");


                                            $query = mysql_query("SELECT fullname FROM register WHERE register_id ='" . $_SESSION['register_id'] . "'");
                                            $numrows = mysql_num_rows($query);

                                            if ($numrows != 0) {
                                                $row = mysql_fetch_assoc($query);
                                                $name = $row['fullname'];
                                            }
                                            ?>
