Question

我在下面有这个代码，我似乎无法理解为什么我在下一页看不到$ pId。我好像他没有在profile.php中的$ pId中发送变量请帮助

  <?php
        include 'config.php';
        include 'dbconnection.php';
session_start();

        if(isset($_REQUEST["pwd"]) && isset($_REQUEST["name"]))
        {
            $password = $_REQUEST['pwd'];
            $name = $_REQUEST['name'];

                    $checkUserPass = mysql_query("SELECT * FROM validPersonnel WHERE Passkey = '$password' and Name = '$name'", $conn);
                    if(mysql_num_rows($checkUserPass) == 1)
                    {   


                        $sql="SELECT PersonnelID FROM validPersonnel WHERE Passkey = :password and Name = :name";
                        $query=$db->prepare($sql);
                        $query->execute(array('name' => $name, 'password' => $password));
                        $row = $query->fetch();
                        $_SESSION['personnelId'] = $row['PersonnelID'];

                        header("Refresh: 1; url=profile/profile.php?p_id={$pId}");
                        echo "<br/><br/>";
                        echo "<script>alert('Logged In.')</script>";


                    }
                    else
                    {
                        //  print_r($query);
                        echo "<br/><br/>";
                        echo "<script>alert('Wrong Password.')</script>";
                        header('Refresh: 1; url=personnelselect.php');
                    }
        }

        mysql_close($conn);
    ?>

下面的代码是我传递$ pId的链接

            if(isset($_SESSION['personnelId']))
            {
            $id = $_SESSION['personnelId'];
            $sqlLoader="Select Name from validpersonnel where PersonnelID = :id";
            $resLoader=$db->prepare($sqlLoader);
            $resLoader->execute(array('id' => $id));
            $row = $resLoader->fetch();
            echo $row['Name'];
            }
        ?>

脚本结束时几乎所有变量都被销毁。我建议使用$ _SESSION变量或通过$ _GET传递变量。

例如存储变量：

$_SESSION['pid'] = $pId;

检索变量：

if (isset($_SESSION['pid'])) $pId = $_SESSION['pid'];

将变量传递给php中的下一页
