Question

使用PHP验证表单存在问题。

表单无需验证即可正常工作 - 信息将填充到我们的数据库中。验证实际上似乎工作正常，但是在提交时，信息无法正确处理到数据库。

我对此很新，所以我提前道歉并感谢任何帮助。

PHP验证脚本：

    if (!empty($_POST)) {
    $validForm = true;
    $errors = array();

    if (empty($_POST['first_name'])) {
        $validForm = false;
        $errors['first_name'] = true;
    }

    if (empty($_POST['last_name'])) {
        $validForm = false;
        $errors['last_name'] = true;
    }

    if (empty($_POST['email_address']) || strpos($_POST['email_address'], '@') === false) {
        $validForm = false;
        $errors['email_address'] = true;
    }

    if (empty($_POST['cust_group'])) {
        $validForm = false;
        $errors['cust_group'] = true;
    }

    if ($validForm) {
    header('Location:http://oi.vresp.com?fid=2b68154d4e');
    exit();
  }
}
?>

HTML表单：

    <table>


        <?php if (!empty($errors)): ?>

        <div style="color:red;font-family:'Arial', Helvetica, sans-serif;font-size:12px;"> 

          <?php if (!empty($errors['first_name'])): ?>
          Please enter your first name.<br />
          <?php endif; ?>

          <?php if (!empty($errors['last_name'])): ?>
          Please enter your last name.<br />
          <?php endif; ?>

          <?php if (!empty($errors['email_address'])): ?>
          Please enter a valid email address.<br />
          <?php endif; ?>

          <?php if (!empty($errors['cust_group'])): ?>
          Please select customer type.<br />
          <?php endif; ?>

  </div>
        <?php endif; ?>

Answer 1

你最好检查一下像这样的数组

if (isset($_POST) && count($_POST) > 1) {

Answer 2

header函数用于将HTTP响应标头发送回用户。不要用它来创建请求标题。

您必须查看cURL（see examples）。

例如，而不是：

header('Location:http://oi.vresp.com?fid=2b68154d4e');

你必须使用cURL：

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'http://oi.vresp.com?fid=2b68154d4e');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'first_name='.$firstName.'&last_name='.$lastName...........);
curl_exec($ch);
curl_close($ch);
