有人会帮我解释语法吗？
它正在运作。我添加了错误消息，一些东西肯定已经坏了。
注意：连接文件正常并且数据库已连接。 connection.php没有问题。问题出在这个代码的某个地方

答案 0 :(得分：3)
此行中有错误：
$fname = $lname = $artname = $email = $phone = $message = $stname = $cname = $state $zip = "";
在=和$state变量之间缺少相同的$zip符号。
更改为：
$fname = $lname = $artname = $email = $phone = $message = $stname = $cname = $state = $zip = "";
