我怎样才能让我的形式工作，使用户可以输入信息并提交进入SQL数据库？我并不真正理解Form = action。我正在使用wordpress。我已经成功地将表从我的数据库中显示，所以我知道我的PHP编码开头是正确的，并且查询应该是正确的。

无处发现表单提交代码！ –

**错字**： - 您错过了$ sql中的结束字符串。写''联系'）“; –

访问者应该如何告诉页面处理信息？是否有一个名为”add“的提交按钮？ – Alfasatwi

您在混合mysql_和mysqli_。使用mysqli_只：

$sql = "INSERT INTO responses (State, City, Place, Address, Day, Time, Host, ContactInformation) VALUES ('$State', '$City', '$Place', '$Address', '$Day', '$Time', '$Host', '$Contact')"; 
$retval = mysqli_query($conn, $sql); 
if(! $retval) { 
    die('Could not enter data: ' . mysqli_error()); 
} 
echo "Entered data successfully\n"; 
mysqli_close($conn);

还有一些在查询一些语法错误，如表名不包含在' '中。请注意，您不需要使用mysqli_select_db，您已经在您的连接字符串中执行了此操作。我确信你的列Contact Information在你的表中没有空白，所以你也需要纠正这个问题。我用ContactInformation，确定这是正确的。

旁注：

数据插入这种方式是SQL注入敞开的。使用准备好的语句！

我可以有更多的语法错误的例子吗？我已经改变了所有出现的东西。当我刷新我的页面时，人们的答案正在消失，我的主题被低估了 –

'$ Day '。为什么你不简单看看mysqli_error输出是什么？ – baao

解析错误：语法错误，意外的'<'in /home3/mlcarelock/public_html/wp-content/plugins/insert-php/insert_php.php(48）：eval （）的第50行代码 –
