php - 向数据库中提交的变量添加撇号

标签 php mysql

我一直在努力处理这段代码。我无法添加像奥布莱恩这样的名字。使用撇号时，我收到错误“更新团队详细信息时出错:您的 SQL 语法中有错误；”当我从表单中去掉撇号时，它运行正常。我哪里失败了？

if (isset($_POST['submit'])): 
$TeamName = mysql_real_escape_string($_POST['TeamName']); 

$sql = "UPDATE Team SET TeamName = 'TeamName'  WHERE id ='$id'";

else:

$id = $_GET['id']; 

$EditTeam=@mysql_query("SELECT *
                      FROM Team 
                      WHERE ID='$id'"); 
if (!$EditTeam) { 
die('<p>Error fetching Team details: ' . 
    mysql_error() . '</p>'); 
} 

$Team = mysql_fetch_array($EditTeam); 

$TeamName =  stripslashes($Team['TeamName']);
<小时/>

这是完整的代码!

最佳答案

在查询中使用 $id 值之前先使用 mysql_real_escape_string。

更好的是，停止使用 ext/mysql 并切换到 PDO/mysqli 并使用参数化查询，这也将正确转义您的数据.
