MySQL 查询错误 - 插入

Question

不知道为什么会返回此错误，我找不到该错误!

有人可以帮我吗？

代码:

$user = user($_SESSION["uid"],"*");
ini_set('display_errors',1); 
error_reporting(E_ALL);
if(isset($_POST["submit"])){
    if(!empty($_POST["message"])){
        if(!empty($_POST["title"])){
            $title = $_POST['title'];
            $message = $_POST['message'];
            $result = mysql_query("INSERT INTO `tickets` (`id`, `username`, `title`, `message`, `date`) VALUES (NULL, '$user', '$title', '$message', NOW()");
            if (!$result) {
                die('Invalid query: ' . mysql_error());
            } else {
                echo "<p class='box green'>Successfully created ticket.</p>";
            }
        } else {
            echo "<p class='box red'>You left the title field blank!</p>";
        }
    } else {
        echo "<p class='box red'>You left the message field blank!</p>";
    }

错误:

Invalid query: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

您忘记在查询末尾关闭括号。

这一行:

$result = mysql_query("INSERT INTO `tickets` (`id`, `username`, `title`, `message`, `date`) VALUES (NULL, '$user', '$title', '$message', NOW()");

应该是:

$result = mysql_query("INSERT INTO `tickets` (`id`, `username`, `title`, `message`, `date`) VALUES (NULL, '$user', '$title', '$message', NOW())");
