此代码适用于验证，但我无法让它与提交一起使用，我不知道为什么。据我所知，问题出在 PHP 末尾的 if 语句中，从 if((strlen($valid_first_name) 开始，我浏览了许多教学网站但无法找出问题所在。我将不胜感激帮助或指导！谢谢！

是的，如果你的结局是这样的，你并没有关闭你的（永无止境的）最后一个：

... && strlen($valid_estimated_ship_date>0))

它应该是：

.. && (strlen($valid_estimated_ship_date)>0))

你提到的最后一行代码有几个问题，试试这个：

if(strlen($valid_first_name) > 0 && strlen($valid_last_name) > 0 && strlen($valid_phone) > 0 && strlen($valid_email) > 0 && strlen($valid_year1) > 0 && strlen($valid_make1) > 0 && strlen($valid_model1) > 0 && strlen($valid_vehicle_type_id1) > 0 && strlen($valid_pickup_city) > 0 && strlen($valid_pickup_state_code) > 0 && strlen($valid_dropoff_city) > 0 && strlen($valid_dropoff_state_code) > 0 && strlen($valid_vehicle_runs) > 0 && strlen($valid_ship_via_id) > 0 && strlen($valid_estimated_ship_date) > 0) {
    //mysql_query(' SQL insert statement');
    header("Location: thanks.html");
}

您缺少一些 strlen 功能。不过，您可能需要考虑整合该代码，这有点麻烦。

当我们做这样的事情时，我们在顶部启动了一个变量，称为

$valid = true;

在其他所有部分中

$valid = false;

最后你可以问

if($valid)
    header("Location: thanks.html");
