Question

我正在尝试运行我的PHP脚本问题。用户应该使用所需的信息填写应用程序，并且一旦提交，就直接进入数据库，并显示在我做的外部应用程序管理器上。嗯..在提交应用程序时，没有任何东西被添加到数据库中。我确保我的SQL查询是正确的结构作为我的数据库的架构，但仍然没有。使用PHPMyAdmin将查询运行到数据库本身，它工作得很好.. 这是我的完整PHP，它将信息添加到数据库中。

<?php

                $sql = mysqli_query($mysqli, "SELECT username FROM tmod WHERE username = '".$_SESSION['user']['username']."'");
                if(isset($_POST['submit']))
                {
                    if (empty($_POST['real']) || empty($_POST['age']) || empty($_POST['why']) || empty($_POST['dif']) || empty($_POST['agree']))
                    {
                        echo '<div class="animated shake">
                                <div class="message error">Please fill in all fields.</div>

                    }
                    else

                    if(mysqli_num_rows($sql) < 1){

            </div>

我导入了我的数据库连接信息。

<?php       require_once ('link/to/my/includes/connection.php'); ?>

connection.php的内容：

<?php
$mysqli = new mysqli("DB HOST", "root", "db pass", "DB NAME"); ?>

以下是数据库中我的tmod表的设置

`AppID` int(11) NOT NULL,
`different` varchar(6000) DEFAULT NULL,
`username` varchar(255) DEFAULT NULL,
`realname` varchar(255) DEFAULT NULL,
`age` int(11) DEFAULT NULL,
`why` varchar(6000) DEFAULT NULL,
`additional` varchar(6000) DEFAULT NULL,
`agree` varchar(1) DEFAULT NULL,
`denied` varchar(255) DEFAULT 'Not Read Yet',
`reply` varchar(1000) DEFAULT NULL,
`save` varchar(255) DEFAULT NULL

Answer 1

您可以添加

  echo("Error description: " . mysqli_error($mysqli));

输出mysql错误。不要离开生产。

您的数据库设置为AppID int(11) NOT NULL

但是你的代码显示：

"INSERT INTO `tmod` (AppID, username,`realname`,age,position,why,different,additional,agree) 
VALUES (NULL,...

您正在将NULL插入AppID。确保AppID在数据库端设置为自动递增。

此外，您要为列position插入一个值，但却缺少表格中的position列。（根据OP评论的完整性添加）。

请记住@Grant对SQL Injection所说的内容并使用PDO。

PHP没有插入数据库
