更新表mysql＆php

Question

我有以下代码，更新分数和日期时可以正常工作。 但是它不会更新该行的名称或国家。 这是否与php字符串有关？？？ 很迷茫！

$userName = "John";
$userCountry = "USA";
$lowestScoreId =  99;
$userPoints = 500;


include 'config.php';


$currentTime = time();

mysql_query("UPDATE highScores SET name = $userName WHERE id='$lowestScoreId'");
mysql_query("UPDATE highScores SET score = $userPoints WHERE id='$lowestScoreId'");
mysql_query("UPDATE highScores SET country =$userCountry WHERE id='$lowestScoreId'");
mysql_query("UPDATE highScores SET date = $currentTime WHERE id='$lowestScoreId'");

Answer 1

您忘记了所设置值的引号。 您可以在1个查询中执行此操作。

UPDATE highScores
SET `name`    = '$userName',
    `score`   = '$userPoints',
    `country` = '$userCountry',
    `date`    = '$currentTime'
WHERE id='$lowestScoreId'"

Answer 2

您应该在一项声明中执行此操作。

$userName = "John";
$userCountry = "USA";
$lowestScoreId =  99;
$userPoints = 500;

include 'config.php';

$currentTime = time();

mysql_query("UPDATE highScores SET name = '$userName', score = '$userPoints', country = '$userCountry', date = '$currentTime' WHERE id='$lowestScoreId'");

Answer 3

另外，您不应再使用PHP mysql_函数。 看一下更新，更快，功能更多的MySQLi 。
