# System Settings

In system settings (*Settings* > *System Settings*) system wide settings fpr Pimcore can be made. Changes should 
be made with care and only by developers. 
These settings are saved in `var/config/system.php`. 


## General 
Contains general settings about timezone, view suffix, additional path variables, default langauge, user interface etc.

 
## Localization & Internationalization (i18n/l10n) 
This settings are used in documents to specify the content language (in properties tab), for objects in localized-fields, 
for shared translations, ... simply everywhere the editor can choose or use a language for the content.
Fallback languages are currently used in object's localized fields and shared translations.

## Debug

Several debugging settings for Pimcore, like Debug Mode and Application Logger settings.

Please note that the core logger (log levels, files, ...) can now directly be configured via Symfony's Monolog configuration.
For details see:

* [Symfony Logging](https://symfony.com/doc/current/logging.html#handlers-writing-logs-to-different-locations)
* [Logging](../19_Development_Tools_and_Details/07_Logging.md) 

### Debug Mode
The Debug Mode is useful if you're developing an application with Pimcore.

With debug-mode on, errors and warnings are displayed directly in the browser, otherwise they are deactivated and the 
error-controller is active (Error Page).

You can restrict the debug mode to an (or multiple) IP address(es), so that it is only active for requests from a 
specific remote address.

In order to include some specific debugging tools (profiler, toolbar, ...), Pimcore implicitly sets the 
environment to `dev` when enabling the debug mode and if **no** environment is 
[defined manually by using an environment variable](../21_Deployment/03_Multi_Environment.md).

If you are using `Pimcore\Mail` to send emails and the Debug Mode is enabled, all emails will be sent to the debug email 
receivers defined in *Settings* > *System Settings* > *Email Settings* > *Debug email addresses*. In addition a debug 
information is attached to the email which shows you to who the email would be sent if the debug mode is disabled.

To check anywhere in your own code if you are working in debug-mode, you can make use of the `PIMCORE_DEBUG` constant.

### DEV-Mode
The development mode enables some debugging features. This is useful if you're developing on the core of Pimcore or when 
creating a plugin. Please don't activate it in production systems!

What exactly does the dev mode:
* Loading the source javascript files (uncompressed & commented)
* Disables some caches (Webservice Cache, ...)
* extensive logging into debug.log
* ... and some more little things


## E-Mail Settings
Settings for default values of Mails sent via `Pimcore\Mail`. 


## Website
System settings about the CMS part of Pimcore.

### EU Cookie Policy Notice
Pimcore has a default implementation for EU cookie policy that looks like as follows. 

![Cookie Policy](../img/system-settings-sample.png)


You can specify your own texts and add your custom detail link using the "Shared Translations".
Just search for "cookie-" in Shared Translations, then you get listed the predefined keys for the cookie 
texts and links:

![Cookie Policy Translation](../img/system-settings2.png)

##### Use a Custom Template Code

```php
<?php
// this example is inside a controller, but you can also inject the listener as dependency
$cookieListener = $this->get(\Pimcore\Bundle\CoreBundle\EventListener\Frontend\CookiePolicyNoticeListener::class);
$cookieListener->setTemplateCode("<b>Your Custom Template</b> ...");
```
 
## MySQL Database
