将下拉值写入SQL表字段

时间：2017-07-08 07:09:49

标签： php sql forms drop-down-menu

在PHP表单中创建一个下拉列表，其中此下拉列表的值应写入SQL表字段。

我几乎可以确定这个问题是name="txtStatus" value="<?php echo $dataSt['Opt'];?>">，但我无法让它发挥作用。

EDITED 这是edit.php的代码，现在我可以让页面上的下拉菜单工作，但$result["Status"]中的值不会被发送到save.php文件，当然也不属于SQL数据库表字段。

您忘记关闭选择标记。关闭php标签后关闭你的select标签。

...</select>....

并查看表单提交后是否获得下拉值。

好的，我明白了，问题不是save.php代码，而是$_POST["txtStatus"]代码，我调用了错误的变量，我调用的是$_POST["Desc"]而不是if( $conn === false ) { die( print_r( sqlsrv_errors(), true)); } $sql = "UPDATE tKelvin32 SET FirstName = ? , LastName = ? , JobTitle = ? , PhoneNumber = ? , PhoneNumberType = ?, EmailAddress = ?, AddressLine1 = ?, City = ?, PostalCode = ?, CountryRegionName = ?, Status = ? WHERE BusinessEntityID = ? "; $params = array($_POST["txtFirstName"], $_POST["txtLastName"], $_POST["txtJobTitle"], $_POST["txtPhoneNumber"], $_POST["txtPhoneNumberType"], $_POST["txtEmailAddress"], $_POST["txtAddressLine1"], $_POST["txtCity"], $_POST["txtPostalCode"], $_POST["txtCountryRegionName"], $_POST["Desc"],$_POST["txtBusinessEntityID"]); 1}}，请参阅以下代码。
