我目前正在从事的项目有一个奇怪的问题。所有代码都运行，没有错误，但没有使用 INSERT 语句将值输入数据库。
代码如下：
pipe.php（调用查询的文件）：
#!/usr/bin/php
<?php
require_once 'includes/Init.php';
Init::initialise();
$email = file_get_contents('php://stdin');
$db = new Db($config['db']);
$mail = new Mail($email);
$emailbody = $mail->getPlainBody();
$emailsubject = $mail->getSubject();
$from = $mail->getHeader("From");
$to = $mail->getTo();
if ($id = Util::getId($emailsubject))
{
$ticket = $db->query_assoc("SELECT * FROM tickets WHERE ticket_id=$id");
if (in_array($from, $config['staff_emails']))
{
//staff reply
$tickets = $ticket['content'].="<ticketsep>$emailbody";
$db->query("UPDATE tickets SET content=$tickets WHERE ticket_id=$id");
mail($ticket['email'], "[$id] A member of staff replied to your ticket: ".$ticket['subject'], $emailbody);
}
else
{
//client reply
$tickets = $ticket['content'].="<ticketsep>$emailbody";
$db->query("UPDATE tickets SET content=$tickets WHERE ticket_id=$id");
foreach ($config['staff_emails'] as $email)
{
mail($email, "[$id] [CLIENT RESPONSE] $emailsubject", $emailbody);
}
}
}
else
{
do
{
$id = rand(1000000, 9999999);
if (!Util::in_array_r($id, $db->query_all('SELECT * FROM tickets')))
{
break;
}
}
while (true);
$db->query("INSERT INTO tickets VALUES \($id, $emailsubject, $emailbody, $from\)");
foreach ($config['staff_emails'] as $email)
{
mail($email, "[$id] [NEW TICKET] $emailsubject", $emailbody);
}
}
?>
此行不起作用，没有插入数据：$db->query("INSERT INTO tickets VALUES \($id, $emailsubject, $emailbody, $from\)");. 我无法测试其他插入查询，因为还没有数据；）
Db 类看起来像这样（请不要对代码样式发表评论，大部分都有效：P）：
<?php
class Db
{
private $link;
/**
* Constructor.
* @param array $dbconfig Array of database configuration:
*
* host - database host
* user - database user
* password - database user password
* dbname - database name
* port - database server port
*/
public function __construct(array $dbconfig)
{
$this->link = mysqli_connect($dbconfig['host'], $dbconfig['user'], $dbconfig['password'], $dbconfig['dbname'], $dbconfig['port']);
if (!$this->link)
{
throw new DatabaseException("Unable to connect to database, please check the settings in the config.php file!");
}
}
/**
* Query the database
* @param string $query SQL query to run
* @return mysqli_result
*/
public function query($query)
{
$result = mysqli_query($this->link, $query);
$this->checkError();
return $result;
}
/**
* Gets the first row of a query.
* @param string $query SQL query
* @return array Enumeriated array of first row contents.
*/
public function query_first($query)
{
$result = mysqli_fetch_row($this->query($query));
$this->checkError();
return $result;
}
/**
* Gets the first row of a query as an associative array
* @param string $query SQL Query
* @return array Associative array of row. Column name->column value.
*/
public function query_assoc($query)
{
$result = mysqli_fetch_assoc($this->query($query));
$this->checkError();
return $result;
}
/**
* Gets all results as array.
* @param unknown $query
* @param string $resulttype
* @return array
*/
public function query_all($query)
{
if (function_exists('mysqli_fetch_all')) # Compatibility layer with PHP < 5.3
$res = mysqli_fetch_all($this->query($query));
else
for ($res = array(); $tmp = mysqli_fetch_array($this->query($query));) $res[] = $tmp;
return $res;
}
public function checkError()
{
if ($this->error != '')
{
throw new DatabaseException("Database Error(s) Occured: $this->error");
}
}
/**
* Get this instance of this object.
* @return Db
*/
public static function _getInstance()
{
return $this;
}
public function __get($name)
{
switch ($name) {
case "error":
$this->error = mysqli_error($this->link);
break;
}
}
}
当我收到电子邮件时，pipe.php 中的所有其他代码行都会运行，但是没有数据添加到数据库中。有谁知道为什么，如果是这样，我怎样才能让它插入数据？
