Question

我无法弄清楚为什么我的数据没有更新到mysql。我相信这个问题介于我在下面显示的两个文件之间。但是，问题是$ sql更新中的语法错误 - 缺少几个逗号。在收到社区的反馈后，我回去用javascript和php验证了表单。

update.php。

<title>update</title>
</head>

<?php

session_start();
// Connect to server and select database.
mysql_connect("localhost", "root", "pwdpwd", "pet_shop")or die("cannot connect"); 
mysql_select_db("pet_shop")or die("cannot select DB");

// get value of id that sent from address bar
$id=$_GET['GroomingID'];



// Retrieve data from database 
$sql="SELECT * FROM grooming WHERE GroomingID = '$id'";
$result=mysql_query($sql);
$rows=mysql_fetch_array($result);
?>
<body>

最后，最后一个文件 - update_ac.php。我收到文件没有更新的错误。

<?php

    session_start();

    if ($_SESSION['username'])
        echo "Welcome, ".$_SESSION['username']."!<br><a href='logout.php'>logout</a>";
    else
        die("You must be logged in!");
    //Session login - all admin pages must include this to interact with DB.
    // Connect to server and select database.
    mysql_connect("localhost", "root", "pwdpwd", "pet_shop")or die("cannot connect"); 
    mysql_select_db("pet_shop")or die("cannot select DB");

    // update data in mysql database 
    $sql="UPDATE grooming SET FirstName='".$_POST['FirstName']."',
    LastName='".$_POST['LastName']."',
    Address='".$_POST['Address']."', 
    City='".$_POST['City']."', 
    State='".$_POST['State']."', 
    Zip='".$_POST['Zip']."', 
    PhoneNumber='".$_POST['PhoneNumber']."',
    Email='".$_POST['Email']."', 
    PetType='".$_POST['PetType']."', 
    Breed='".$_POST['Breed']."', 
    PetName='".$_POST['PetName']."', 
    NeuteredOrSpayed='".$_POST['NeuteredOrSpayed']."',
    PetBirthday='".$_POST['PetBirthday']."' WHERE GroomingID='".$_POST['GroomingID']."'";

    $result=mysql_query($sql)or
    die ("<br>Could not Update");


    // if successfully updated. 
    if($result){
    echo "Successful";
    echo "<BR>";
    echo "<a href='Welcome.php'>View result</a>";
    }

    else {
    echo "ERROR";
    }

    ?>

Answer 1

您的PhoneNumber=...声明中Email=...和UPDATE之间需要逗号。

哦，NeuteredOrSpayed=...和PetBirthday=...。

另请注意评论;保护您的数据库并在您的代码中实现一些调试。
