Question

当我试图在我的论坛中发布主题时，这就出现了：

列数与第1行的值计数不匹配

有人可以看到 ERROR 吗？ Tnx :)

这是我的代码：

<?php
session_start();
if ($_SESSION['uid'] == "") {
    header("Location: index.php");
    exit();
}
if (isset($_POST['topic_submit'])) {
    if (($_POST['topic_title'] == "") && ($_POST['topic_content'] == "")) {
        echo "You did not fill in both fields. Please retun to the previous page.";
        exit();
    } else {    
        include_once("connect.php");
        $cid = $_POST['cid'];
        $title = $_POST['topic_title'];
        $content = $_POST['topic_content'];
        $creator = $_SESSION['uid'];
        $sql = "INSERT INTO topics (category_id, topic_title, topic_creator, topic_date, topic_reply_date) VALUES ('".$cid."', '".$title."', '".$creator."', now(), now())";
        $res = mysql_query($sql) or die(mysql_error());
        $new_topic_id = mysql_insert_id();
        $sql2 = "INSERT INTO posts (category_id, post_creator, post_content, post_date) VALUES ('".$cid."', '".$new_topic_id."', '".$creator."', '".$content."', now())";
        $res2 = mysql_query($sql2) or die(mysql_error());
        $sql3 = "UPDATE categories SET last_post_date=now(), last_user_posted='".$creator."' WHERE id='".$cid."', LIMIT 1";
        $res3 = mysql_query($sql3) or die(mysql_error());
        if (($res) && ($res2) && ($res3)) {
            header("Location: view_topic.php?cid=".$cid."&tid=".$new_topic_id);
        } else {
            echo "There was a problem creating your topic. Please try again.";
        }
    }
}
?>

这就是你的错误：

$sql2 = "INSERT INTO posts (category_id, post_creator, post_content, post_date) VALUES ('".$cid."', '".$new_topic_id."', '".$creator."', '".$content."', now())";

您要将5个值（$cid，$new_topic_id，$creator，$content，now()）插入4列（category_id，{ {1}}，post_creator，post_content）。因此列数（4）与值计数（5）不匹配。

此外，您可能会遇到另一个错误，因为您在post_date之前有一个额外的逗号：

LIMIT

列数与第1行的值计数不匹配（错误）
