Question

我正在尝试验证输入到我正在使用PHP处理的表单提交中的数据，首先要确保填写字段，然后确保数据是正确的但出于某种原因无论我尝试做什么，数据都会被提交给数据库。

// example of validation (this is just duplicated for 4 fields)
if (isset($_POST["fullname"]) && !empty($_POST["fullname"])) {
  header('Location: http://mywebsite.com/error');
} else {
  // Trying to get it to redirect at all
  header('Location: http://mywebsite.com/error');
}

$email = $_POST['email'];
// using google code email validation
include('EmailAddressValidator.php');
$validator = new EmailAddressValidator;
if ($validator->check_email_address($email)) {
    // Email address is technically valid
} else {
    header('Location: http://mywebsite.com/error');
}

// If this line is reached, submit the data to the DB but there's no way      this line should be reached because the very first if & else statement should send it to the error page.

任何帮助将不胜感激！此时此刻已经尝试解决这个问题。

Answer 1

尝试使用header.please重定向后添加exit;，请参阅下面的示例：

header('Location: http://mywebsite.com/error');exit;

以下是您应如何提交表单的示例：

// example of validation (this is just duplicated for 4 fields)
if (isset($_POST["fullname"]) && isset($_POST["email"])) {
    // using google code email validation
    include('EmailAddressValidator.php');
    $validator = new EmailAddressValidator;

    $email = $_POST['email'];

    if (empty($_POST["fullname"]) && !$validator->check_email_address($email)) {
        header('Location: http://mywebsite.com/error');exit;
    } else {
        // enter into data here
    }
}

首先制作第一个如果或不是AND ... if（isset（$ _ POST [＆＃34; fullname＆＃34;]）||！empty（$ _ POST [＆＃34; fullname＆＃34;]））第二，你必须说if（$ validator-＆gt; check_email_address（$ email）） //在DB中插入

对表单的后端验证被忽略
