我的支持票务网站已经解决了所有问题，除了我的新票据表单没有将值发布到数据库。这就是我所拥有的：
<?php
ob_start();
session_start();
include 'dbconnect.php';
if( !isset($_SESSION['user']) ) {
header("Location: index.php");
exit;
$error = false;
}
if ( isset($_POST['btn-cancel']) ) {
header("Location: home.php");
exit;
}
if ( isset($_POST['btn-signup']) ) {
// get form results
$text = $_POST['description'];
$text = strip_tags($text);
$userid = $_POST['user'];
$problem = $_POST['problem'];
$room = $_POST['room'];
$status = 1;
$datetime = date('Y-m-d G:i:s');
// description validation
if (empty($text)) {
$error = true;
$textError = "Please describe the problem.";
} else if (strlen($text) > 200) {
$error = true;
$textError = "Description must be less than 200 characters in length.";
}
// dropdown validation
if ($problem < 1){
$error = true;
$problemError = "Please choose a category and problem.";
} else if ($room < 1) {
$error = true;
$roomError = "Please choose a building and a room number.";
// if there's no error, continue to signup
if( !$error ) {
$query = "INSERT INTO job (User_UserID,Problem_ProblemID,Status_StatusID,Room_RoomID,Description,Date_Time) VALUES({$userid},{$problem},{$status},{$room},'{$text}',{$dateTime})";
echo '$query';
$res = mysqli_query($conn,$query);
if ($res) {
$errTyp = "success";
$errMSG = "Successfully submited ticket";
unset($text);
unset($problem);
unset($room);
unset($datetime);
} else {
$errTyp = "danger";
$errMSG = "Something went wrong, try again later.";
}
}
}
}
?>

糟糕，您不会关闭if ($problem < 1){
$error = true;
$problemError = "Please choose a category and problem.";
} else if ($room < 1) {
$error = true;
$roomError = "Please choose a building and a room number.";
，因此始终会跳过else if。
看起来狡猾的代码的一部分是这些行：
INSERT您的$datetime = date('Y-m-d G:i:s');
//...
$query = "INSERT INTO job (User_UserID,Problem_ProblemID,Status_StatusID,Room_RoomID,Description,Date_Time)
VALUES({$userid},{$problem},{$status},{$room},'{$text}',{$dateTime})";
^^^^^^^^^^^
将类似$dateTime，因此SQL语句将为：
2016-12-09 11:43:42这是语法错误。请注意，您的INSERT INTO job (...) VALUES(..., 'This is my text', 2016-12-09 11:43:42)
字段周围有引号以将其保留为单个元素，但您的日期不会。使用$text将解决此问题，但无法保证不存在其他问题......
