我创建了两个表单，一个是注册表单，另一个是选择用户来和离开的日期。我在第二页中调用了用户的用户名..虽然我收到了它，但我收到一条消息“错误”，并且我的数据库上没有任何更新。这是我的第二页文件..我做错了什么？
<?php
session_start();
$EntryError=$ExitError="";
if (isset($_POST['submit'])){
$entrydate = $exitdate = "";
$errorOccured = false;
if (isset($_POST['tsmdate'])){
$entrydate = trim($_POST['tsmdate']);
if (strlen($entrydate) == 0){
$EntryError = "date is missing";
$errorOccured = true;
}
}
else{
$EntryError = "date is missing";
}
// checking for last name
if (isset($_POST['tsmexit'])){
$exitdate = trim($_POST['tsmexit']);
if (strlen($exitdate) == 0){
$ExitError = "First Name is missing";
$errorOccured = true;
}
}
else{
$ExitError = "last Name is missing";
}
$ids=$_SESSION['tsmUserName'];
var_dump($_SESSION);
if(!$errorOccured){
require_once("connection.php");
$my_query="INSERT INTO timing (No, Entry Date and Time, Exit Date and Time, user_id) VALUES (NULL,'$EntryError','$exitdate','$ids')";
$result=mysqli_query($connection,$my_query);
if($result)
{
echo 'thank you';
}
else
{
echo 'error';
}
mysqli_close($connection);
}
}
?>

最佳答案
将 INSERT 查询更改为此
$my_query="INSERT INTO timing (`No`, `Entry Date and Time`, `Exit Date and Time`, `user_id`) VALUES (NULL,'$EntryError','$exitdate','$ids')";
确保任何数据库字段名称中是否有空格，那么它应该在`(后面的tic)内
