这是模型：
function store_product($data)
{
$insert = $this->db->insert('products', $data);
return $insert;
}
但问题是当我上传产品时可以说
火灾，整个网站发生故障并发出500内部错误。 我的网站是在dreamhost上，我在崩溃后将文件上传到godaddy，它是相同的，给出500内部错误。但是当我上传整个网站时，我在崩溃之前备份了它，它又重新开始工作了。我不知道它看起来像这个代码打破了一些文件。我曾两次联系支持团队，他们说错误不在他们身边。company_do_upload（）
答案 0 :(得分：0)
您所拥有的日志片段显示的错误不是由您的代码触发，而是由配置文件触发。 line 195 /dh/apache2/template/etc/mod_sec2/99_dreamhost_rules.conf的内容是什么？我想如果你的代码中的某些东西实际上是在触发500错误，那么日志中会引用你的PHP文件。您的日志片段并未表明情况属实。
如果是您的代码，请在不同的地方调用日志记录功能并查看它的位置。这就是我在httpd日志对我没有帮助时所做的事情。这是我使用的日志记录功能：
function logit($msg){
try {
$fh=fopen('/tmp/file.log','a');
fwrite($fh,date("Ymd His")."\t$msg\n");
fclose($fh);
} catch (Exception $ex){
// Forget it!
} // try..catch
} // logit
它会自动为发送到文件的消息添加时间戳。该函数在每次调用后故意关闭日志文件以强制缓冲区刷新，以确保您的程序死亡，日志将尽可能最新。这帮助我摆脱了许多紧张的局面。我在例程的开头和结尾调用日志导致问题：
function foo(){
logit("Foo():start");
// do something
logit("Starting potential trouble: some potentially troublesome value='$bar'");
// The single quotes around $bar help if $bar is not assigned a value
// problem code
logit("Foo():done");
} //foo
请务必确保fopen()调用中的目录和文件可由Web服务器进程写入！话虽如此，你是否有PHP将上传的文件放在company_do_upload()的Web服务器可写的路径上？
