来自表单数据的PHP变量

标签： php html mysql forms

我有一个PHP脚本，我试图用来从html文档中提取表单数据，处理它然后将数据写入mysql数据库表。

我可以让脚本写入mysql数据库ok，但它只传递空字符串，我在脚本开头声明变量为空字符串，然后从表单元素传递$ _POST数据，但是它似乎没有起作用，我已经尝试了所有引用和连接的方式而没有成功。

当我回显变量时，它们只是空的，继承代码，它是相当长的形式，但大多数变量都以相同的方式处理，任何帮助都会非常感激，我对PHP很新。

尝试使用类似的东西，以获得正确的内容：

function give_get($varname)
{
      if (isset($_GET[$varname])) return trim($_GET[$varname]);
      else return "";
}

function give_post($varname)
{
      if (isset($_POST[$varname])) return trim($_POST[$varname]);
      else return "";
}

我会尝试为您提供主要概念，然后您可以将其应用于您的案例。假设您有这样的表格：

<form action="path/to/handler/file.php" method="post">
    Name:  <input type="text" name="name">
    Email: <input type="text" name="email">
    Phone: <input type="text" name="phone">
    <input type="submit" name="submit" value="Submit">
</form>

现在在处理程序文件中：

if (!empty($_POST)) {
    foreach ($_POST as $key => $value) {
        ${$key} = htmlspecialchars(trim($value), ENT_QUOTES, 'UTF-8');
    }
}

这段代码将为您提供下一个代码：

// supposing that the next values are those the user entered
$name  = "john doe";
$email = "john.doe@gmail.com";
$phone = "55555555";

现在你可以处理这些变量（$name，$email和$phone）来做你想做的事情，比如检查变量是否为空，检查它是否为空是否有效的电子邮件，检查它是否是数字等等，然后将它们保存在数据库中。
