Question

所以我创建了一个编辑个人资料页面，一切都很顺利。但后来我想使用类似的代码来更新我的数据库中的另一个东西。它是一个非常奇怪的bugg，因为当我添加许多需要更新的值时，它拒绝工作。

<?php

session_start();

if(isset($_POST['submit'])){
$Creator = $_SESSION['username'];
$dbName = $_POST['Name'];
$dbBase_damage = $_POST['Base_damage'];
$dbDamage = $_POST['Damage'];
$dbPellets = $_POST['Pellets'];
$dbAttackspeed = $_POST['Attackspeed'];
$dbRS = $_POST['RS(first)'];
$dbRS2 = $_POST['RS(consecutive)'];
$dbLoaded = $_POST['Loaded'];
$dbReserve = $_POST['Reserve'];
$dbCritical = $_POST['Critical'];
$dbAbility = $_POST['Ability'];
$dbPiece_set = $_POST['Piece_set'];
$dbBonus_set = $_POST['Bonus_set'];
$dbDescription = $_POST['Description'];

if ($dbName && $dbBase_damage && $dbDamage && $dbAttackspeed && $dbLoaded && $dbCritical) {

mysql_connect ("localhost", "root", "") or die ("Could not connect");
mysql_select_db("weapons") or die ("Could not connect to the database");    

$wepquery = mysql_query("SELECT * FROM weapon WHERE Creator='$Creator' AND Name='$dbName'") or die ("The query could not be completed, please try again later!");
if (mysql_num_rows($wepquery) != 0) {

mysql_query ("

UPDATE weapon SET Base_Damage='$dbBase_damage', Damage='$dbDamage', 
Pellets='$dbPellets', Attackspeed='$dbAttackspeed', RS(first)='$dbRS', RS(consecutive)='$dbRS2', 
Loaded='$dbLoaded', Reserve='$dbReserve', Critical='$dbCritical', Ability='$dbAbility', Piece_set='$dbPiece_set', 
Bonus_set='$dbBonus_set' Description='$dbDescription' WHERE Creator='$Creator' AND Name='$dbName'

") or die ("Could not update!");
echo "It just werks!";

}else echo ("That username could not be found!");
}else echo ("Something went wrong!"); 
    }
    ?>

当我使用这段代码时，我得到一个错误，'Base_Damage'是未定义的索引。但是当我删除'Base_Damage'时，它根本无法更新。我已经仔细检查了数据库并用它创建了“武器创意”而没有任何问题。但由于某种原因，当我减少需要更新的值的数量时，它工作正常。如果你想知道“$ Creator = $ _SESSION ['username'];”，我会根据从“nav.php”登录的人获取Creator用户名我的HTML代码：

<!DOCTYPE html>

<html>
<head>

任何人都可以提供帮助？：P

Answer 1

我猜你的if语句是不可读的，这就是为什么你不能更新

首先您的名字name="Base_damage"与您的变量索引$dbBase_Damage = $_POST['Base_Damage'];

应该是

    $dbBase_Damage = $_POST['Base_damage']; // with small d

尝试重播这个

     if ($dbName && $dbBase_Damage && $dbDamage && $dbAttackspeed && $dbLoaded && $dbCritical)

修改

在您的查询中
替换此

RS(first)='$dbRS', RS(consecutive)='$dbRS2'

通过

`RS(first)`='$dbRS', `RS(consecutive)`='$dbRS2'

<强> EDIT2：

请替换

or die ("Could not update!");

带

or die(mysql_error()); // like that you can see what error or what goes wrong.

<强> EDIT3。

Bonus_set='$dbBonus_set' , Description= ^^//you missed coma here

无法更新SQL数据库
