Question

我必须建立一个系统，系统需要添加新信息的过程。流程是添加员工携带的新信息的过程，其中所有信息，名称和员工ID将插入mysql数据库。当我尝试这个过程时，我发现staff_id和staff_name在数据库mysql中是空的。

这是我的addStaff.php

<?php
include("authenticationStaff.php");
include ("dbase.php");  

        $query= "SELECT * FROM staff WHERE staff_name ='".$_SESSION['SESS_STAFF_NAME']."'";
        $result = mysql_query($query);


        $row = mysql_fetch_array($result);
        $id = $row["id"];
        $staff_id=$row["staff_id"];
        @mysql_free_result($result);
?>
<html>
<head>
<script>

function Validate()
{
    if (document.addStaff.project_name.value == '') 
    {
       alert('Please Insert Project Name!');
       document.addStaff.project_name.focus();
       return false;
    }
    if (document.addStaff.project_id.value == '') 
    {
       alert('Please Insert Project ID !');
       document.addStaff.project_id.focus();
       return false;
    }
    if (document.addStaff.location.value == '') 
    {
       alert('Please Insert Location!');
       document.addStaff.location.focus();
       return false;
    }
    if (document.addStaff.cost.value == '') 
    {
       alert('Please Insert Cost!');
       document.addStaff.cost.focus();
       return false;
    }
    if (document.addStaff.pic.value == '') 
    {
       alert('Please Insert Person In Charge!');
       document.addStaff..pic.focus();
       return false;
    }
    if (document.addStaff.detail.value == '') 
    {
       alert('Please Insert Detail about the Project!');
       document.addStaff.detail.focus();
       return false;
    }
}
</script>
</head>

$row = mysql_fetch_array($result, MYSQL_BOTH); // using numeric index or array index

    $staff_id = $row['staff_id'];
    $project_name = $row['project_name'];

这是我的addStaff_process.php

<?php
include("authenticationStaff.php");
include ("dbase.php");

    extract( $_POST );

    $idURL = $_GET['id'];
    $project_name = $_POST['project_name'];
    $location = $_POST['location'];
    $cost= $_POST['cost'];
    $pic= $_POST['pic'];
    $detail = $_POST['detail'];
    $project_id = $_POST['project_id'];
    $staff_id = $_POST['staff_id'];
    $staff_name = $_SESSION['SESS_STAFF_NAME'];


$result ="INSERT INTO inter1 (project_name,location,cost,pic,detail,project_id)
 VALUES ('$project_name','$location','$cost','$pic','$detail','$project_id')";
$query = mysql_query ($result, $conn);

if(mysql_num_rows($query)){
 echo "<script type='text/javascript'> window.location='pageStaff.php'</script>";
}
  else{

$query1 = "UPDATE inter1 SET staff_name = '$staff_name',staff_id = '$staff_id' WHERE staff_name=$idURL";
$result1 = mysql_query ($query1, $conn);


if($result1){
 echo "<script type='text/javascript'> window.location='pageStaff.php'</script>";
    }
}
?>

有人可以看到我出错的地方吗？如果您需要更多信息，请告诉我。感谢。

您需要在访问会话值的每个页面的开头使用session_start();。

为什么数据没有添加到数据库mysql中？
