提交php表单

Question

我正在编写一个 php 代码，用户在其中输入各种详细信息，然后以表单形式提交它们。但是，当我提交它时，我得到了一个错误：

警告：mysql_query() [function.mysql-query]: 拒绝用户访问 'sifeiitd'@'localhost'（使用密码：NO） /home/sifeiitd/public_html/wh.php 在第 95 行

警告：mysql_query() [function.mysql-query]：到服务器的链接 无法在线建立/home/sifeiitd/public_html/wh.php 95

我的php代码是

<?php
                //include the connection file

                require_once('functions/connection.php');
                require_once('functions/functions.php');

                $display_query = mysql_query("SELECT * FROM eportal");

                    echo "<table id='pageTable'><thead><tr><th>Item code</th><th>Image</th><th>Description</th><th>Cost</th></tr></thead>";
                    echo "<tbody>";
                    while($row = mysql_fetch_array($display_query)){
                        print "<tr><td>".$row['itemid']."</td><td>"."</td><td>".$row['description']."</td><td>";
                        print "&#8377;".$row['cost']."</td></tr>";
                    }
                    echo "</tbody>";
                    echo "</table>";
                    mysql_close($connection);

            ?>
            <?php

            //save the data on the DB and send the email

            //If the user has submitted the form
            if($_POST['submit']){

                        $result = mysql_query("INSERT INTO `wh_order` (`name`, `email`, `contact`, `itemid`, `itemquantity`, `ip`,`message`) VALUES('".$name."','".$email."','".$contact."','".$itemid."','".$itemquantity."','".$ip."','".$message."')");

用户 'sifeiitd'@'localhost' 的访问被拒绝（使用密码：否）

对我来说似乎是一个非常明显的错误。检查您的 mysql_connect() 声明，可能在 connection.php 中。
