在localhost上更正html标签，但在web甚至相同的PHP代码和数据库中进行了清理

问题描述：

I'm trying to figure out a strange issue I stumbled on:

Locally and on external server I use the same web environment thanks to Ansible and Vagrant.

I use Ubuntu, Apache Webserver, MySQL, PHP 7, Codeigniter 3.

On the edit form I see on localhost correct HTML tags.

But when I open the same page from the cloud (an external Webserver) the HTML tags are sanitized on Chrome and Firefox.

What's the cause of this behaviour and how can I prevent the sanitized html tags?

我试图找出一个我偶然发现的奇怪问题： p>

在本地和外部服务器上，由于Ansible和Vagrant，我使用相同的Web环境。 p>

我使用Ubuntu，Apache Webserver，MySQL，PHP 7，Codeigniter 3. p>

在编辑表单上，我在localhost上看到正确的HTML标记。 p>

但是当我从云（外部Web服务器）打开同一页面，在Chrome和Firefox上清理HTML标签。 p>

此行为的原因是什么？如何防止已清理的html标记？ p> div>

If you haven't bothered to set CI_ENV correctly in either your configuration file application/config/config.php or via apache (either in .htaccess or apache conf) then you might get different behavior on the two different machines.

You should also check application/config/config.php for this value and see what it's set to:

$config['global_xss_filtering'] = FALSE;

Obviously, if you've bothered to define different config.php values in these locations, you may need to check them also:

application/config/development/config.php
application/config/testing/config.php
application/config/production/config.php

As a sanity check, you might want to define a controller method like this and see if it outputs different values on your respective machines:

public function ci_check() {
    echo CI_ENV;
}

If you find that the machines have different CI_ENV values, it may be that each machine is loading a different configuration file for config value global_xss_filtering. This might cause the problem you are seeing. Sort of hard to say without seeing more code.
