如何将mysql_real_escape_string（）添加到此:::

$result = mysql_send("INSERT customers SET user='$username', pword='$pass1', 
                      firstname='$firstname', lastname='$lastname', email='$email', 
                      active='No', activecode='$activecode', dateofbirth='$dateofbirth',

$result = mysql_send("  INSERT  customers
                        SET     user='".mysql_real_escape_string($username)."', 
                                pword='".mysql_real_escape_string($pass1)."', 
                                firstname='".mysql_real_escape_string($firstname)."', 
                                lastname='".mysql_real_escape_string($lastname)."', 
                                email='".mysql_real_escape_string($email)."', 
                                active='No', 
                                activecode='".mysql_real_escape_string($activecode)."', 
                                dateofbirth='".mysql_real_escape_string($dateofbirth)."', 
                                gender='".mysql_real_escape_string($gender)."', 
                                title='".mysql_real_escape_string($title)."', 
                                occupation='".mysql_real_escape_string($occupation)."', 
                                address='".mysql_real_escape_string($address)."', 
                                city='".mysql_real_escape_string($city)."', 
                                country='".mysql_real_escape_string($country)."', 
                                zip='".mysql_real_escape_string($zip)."', 
                                mobile='".mysql_real_escape_string($mobile)."', 
                                telephone='".mysql_real_escape_string($telephone)."', 
                                fax='".mysql_real_escape_string($fax)."', 
                                website='".mysql_real_escape_string($website)."'
                    ");

Answer 2

我这样做（假设HTML表单的字段名称与数据库字段名称完全匹配）：

$fields = explode(" ","user pword firstname lastname email ative activecode dateofbirth gender title occupation address city country zip mobile telephone fax website");

$_POST['active'] = "Mo"; // I know it's kinda dirty but it works. 
$sql = "INSERT INTO customers SET ".makeDdbSet($fields);

function makeDdbSet($fields) {
  $q='';
  foreach ($fields as $v) $q.="`$v` = '".mysql_real_escape_string($_POST[$v])."', ";
  return trim($q,", ");
}

看起来很整洁。

逃离是相当老派的。相反，使用预准备语句来分隔查询和数据。

这可以为您节省很多的麻烦。

$sql = "INSERT customers SET user=:user, pword = :pword .....";
$sth = $dbh->prepare($sql);
$sth->execute(array('user => $username, 'pword' => $password));

根据您从何处获取数据，您也可以直接将其存储在数组中。

例如，如果您从表单获取大量数据，使用变量名称pword，user等，则可以直接使用该数组

$sth->execute($_POST);

Answer 4

也许你可以花一些时间查看Doctrine ORM。

保存到数据库将如下所示：

$customer = new Customer();
$customer->fromArray($data); // $data = array("firstname"=>"John", ...)
$customer->save();

所有内容都将被转义，您的程序也会更具可读性......

$result = mysql_send("INSERT customers SET user='$username', pword='$pass1', firstname='".mysql_real_escape_string($firstname)."', lastname='".mysql_real_escape_string($lastname)."', email='".mysql_real_escape_string($email)."', active='No', activecode='".mysql_real_escape_string($activecode)."', dateofbirth='".mysql_real_escape_string($dateofbirth)."', gender='".mysql_real_escape_string($gender)."', title='".mysql_real_escape_string($title)."', occupation='".mysql_real_escape_string($occupation)."', address='".mysql_real_escape_string($address)."', city='".mysql_real_escape_string($city)."', country='".mysql_real_escape_string($country)."', zip='".mysql_real_escape_string($zip)."', mobile='".mysql_real_escape_string($mobile)."', telephone='".mysql_real_escape_string($telephone)."', fax='".mysql_real_escape_string($fax)."', website='".mysql_real_escape_string($website)."'");

PHP保护mysql注入查询。
