我正在使用邮件系统，我使用的是PHP和MySQL，一切正常，除了read_pm.php中的回复函数外，我可以发送，读取和接收邮件，但当我阅读邮件并尝试回复时，我收到错误“发送邮件时发生错误”。当它无法到达数据库时发生所以我想它应该是我的查询的东西，但无法弄清楚，我检查了代码的每一部分，并找不到错误，任何想法？回复功能在PM系统中不起作用
有数据库中的两个表，一个用户和下午一个消息 这是read_pm.php：
<?php
//We check if the user is logged
if(isset($_SESSION['id']))
{
//We check if the ID of the discussion is defined
if(isset($_GET['id']))
{
$id = intval($_GET['id']);
//We get the title and the narators of the discussion
$req1 = mysqli_query($link,'select title, user1, user2 from pm where id="'.$id.'" and id2="1"');
$dn1 = mysqli_fetch_array($req1);
//We check if the discussion exists
if(mysqli_num_rows($req1)==1)
{
//We check if the user have the right to read this discussion
if($dn1['user1']==$_SESSION['id'] or $dn1['user2']==$_SESSION['id'])
{
//The discussion will be placed in read messages
if($dn1['user1']==$_SESSION['id'])
{
mysqli_query($link,'update pm set user1read="yes" where id="'.$id.'" and id2="1"');
$user_partic = 2;
}
else

mysqli_query($link,'update pm set user2read="yes" where id="'.$id.'" and id2="1"');
$user_partic = 1;
}
//We get the list of the messages
$req2 = mysqli_query($link,'select pm.timestamp, pm.message, users.id as userid, users.email,users.firstname from pm, users where pm.id="'.$id.'" and users.id=pm.user1 order by pm.id2');
//We check if the form has been sent
if(isset($_POST['message']) and $_POST['message']!='')
{
$message = $_POST['message'];
//We remove slashes depending on the configuration
if(get_magic_quotes_gpc())
{
$message = stripslashes($message);
}

$message = mysqli_real_escape_string(nl2br(htmlentities($message, ENT_QUOTES, 'UTF-8')));

这是new_pm.php这是发送新邮件和正常工作：

能否请您更改为检查'mysqli_query（$ link，'insert into pm（id，id2，title，user1，user2，message，timestamp，user1read，user2read）values（“'。$ id。'”，“'。（intval（mysqli_num_rows（$ req2 ））+ 1）。'“，”“，”'。$ _ SESSION ['id']。'“，”“，”'。$ message。'“，”'.time（）。'“，”“ ，“”）'）&& mysqli_query（$ link，'update pm set user'。$ user_partic.'read =“yes”where id =“'。$ id。'”a nd id2 =“1”'）' –
改变了它，但相同的结果呢 – Babak
