我正在编写一个 php 代码，用户在其中输入各种详细信息，然后以表格形式提交它们。但是，当我提交它时，我得到了一个错误：
警告：mysql_query() [function.mysql-query]：第 95 行 /home/sifeiitd/public_html/wh.php 中的用户 'sifeiitd'@'localhost' 的访问被拒绝（使用密码：否）
警告：mysql_query() [function.mysql-query]：无法在第 95 行的 /home/sifeiitd/public_html/wh.php 中建立到服务器的链接
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>".$row['description']."</td><td>";
print "₹".$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']){
//protect the posted value then store them to variables
$name = protect($_POST['name']);
$email = protect($_POST['email']);
$contact=protect($_POST['contact']);
$itemid=protect($_POST['itemid']);
$itemquantity=protect($_POST['itemquantity']);
$ip = gethostbyname($_SERVER['REMOTE_ADDR']);
$message = protect($_POST['message']);
//Check if the username or password boxes were not filled in
if(!$name || !$email || !$contact || !$itemid){
//if not display an error message
echo "<center>Fields marked with <strong>( * ƥ</strong> are mandatory!</center>";
}else{
//if the were continue checking
$result = mysql_query("INSERT INTO `wh_order` (`name`, `email`, `contact`, `itemid`, `itemquantity`, `ip`,`message`) VALUES('".$name."','".$email."','".$contact."','".$itemid."','".$itemquantity."','".$ip."','".$message."')");
//send the email with the order
if($result)
{
//send the email
$to = "ps@xyz.com";
$subject = "New order for Weaving Hope";
//headers and subject
$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
$headers .= "From: ".$name." <".$email.">\r\n";
