如何让我的表单工作，以便用户可以输入信息并提交进入sql数据库？我不太了解Form = action。我正在使用wordpress。我已经成功地从我的数据库中拉出表格，所以我知道我的PHP编码开始是正确的，查询应该是正确的。

Answer 1

您正在混合mysql_和mysqli_。仅使用mysqli_：

$sql = "INSERT INTO responses (State, City, Place, Address, Day, Time, Host, ContactInformation) VALUES ('$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);

您的查询中也存在多个语法错误，例如：表名不包含在' '中。请注意，您不需要使用mysqli_select_db，您已在连接字符串中执行此操作。我确定你的专栏Contact Information在你的表格中没有空格，所以你也需要纠正这个问题。我使用过ContactInformation，请确保这是正确的。

旁注：

以这种方式插入数据对sql-injection非常开放。请改用预备语句!!
