500 Internal Server Error - All Ajax calls, PHP
提问by user1065700
Issue
问题
I'm receiving the same error (500 Internal Server error) for all AJAX calls on a site I'm developing on my localhost (WAMP). I'm beginning to think that it might be the way my server is set up. Maybe I'm missing a PHP extension or something? Any help would be much appreciated.
我在本地主机 (WAMP) 上开发的站点上的所有 AJAX 调用都收到相同的错误（500 内部服务器错误）。我开始认为这可能是我的服务器的设置方式。也许我错过了一个 PHP 扩展或什么？任何帮助将非常感激。

I know the code works fine because i've navigated to the ajax action on my browser. Also the code actually saves data to the database so I know it's finding the correct script and running it ok.
我知道代码运行良好，因为我已经导航到浏览器上的 ajax 操作。此外，代码实际上将数据保存到数据库中，因此我知道它正在查找正确的脚本并正常运行。

Add this code at the top of your PHP:
将此代码添加到 PHP 的顶部：
ini_set('display_errors', 1);
error_reporting(E_ALL);
That will show you what the problem is in your PHP code. If it's a syntax error (seems quite likely for a code 500), then you'll need to either enable these options in your php.ini, httpd.confor .htaccessfiles. Alternatively, just take a look in your web server error log for the issue.
这将显示您的 PHP 代码中的问题所在。如果是语法错误（对于代码 500 来说似乎很可能），那么您需要在php.ini,httpd.conf或.htaccess文件中启用这些选项。或者，只需查看您的 Web 服务器错误日志中的问题。
A 500 error is not a problem with your JS - it's server-side.
500 错误不是你的 JS 的问题——它是服务器端的。

I've finally got to the bottom of this. In fact there was nothing wrong with the code. However, I did have a plugin that wasn't being found during bootstrapping. This was then being run through my error handler which was changing the header to a 500. Once I'd removed the unfound plugin everything was fine.
我终于明白了这一点。事实上，代码没有任何问题。但是，我确实有一个在引导过程中没有找到的插件。然后通过我的错误处理程序运行它，将标题更改为 500。一旦我删除了未找到的插件，一切都很好。
Stupid mistake to make I suppose!
愚蠢的错误，我想！
