General parameters
==================

Configuration files
-------------------

The default configuration file is ``/etc/service-desk/config.inc.php``, it contains all default values.
To edit configuration, you should create ``/etc/service-desk/config.inc.local.php`` and override needed parameters:

.. code-block:: php

    <?php
    // Override config.inc.php parameters below

    ?>

.. warning:: 
  Do not copy ``config.inc.php`` into ``config.inc.local.php``, as the first one includes the second.
  You would then create an infinite loop and crash your application.

Multi tenancy
-------------

You can load a specific configuration file by passing a HTTP header.
This feature is disable by default. To enable it:

.. code-block:: php

   $header_name_extra_config = "SSP-Extra-Config";

Then if you send the header ``SSP-Extra-Config: domain1``, the file
``/etc/service-desk/config.inc.domain1.php`` will be loaded.

Using Apache, we may set such header using the following:

.. code-block::

    <VirtualHost *:80>
       ServerName ssp.domain1.com
       RequestHeader setIfEmpty SSP-Extra-Config domain1
       [...]
    </VirtualHost>

Using Nginx, we could use instead:

.. code-block::

   server {
       [...]
       location ~ \.php {
           fastcgi_param HTTP_SSP_EXTRA_CONFIG domain1;
           [...]
       }

Language
--------

.. tip:: Lang is selected from browser configuration. If no matching language is found, the default language is used.

Set default language in ``$lang``:

.. code-block:: php

    $lang = "en";


.. tip:: You can override messages by creating lang files in configuration directory:

* ``conf/`` directory for service-desk archive
* ``/etc/service-desk`` directory for rpm/deb packages

For example, you can create a customized file: ``/etc/service-desk/en.inc.php``.

Language is picked according to browser choice among the available ones. All languages
are allowed by default, to restrict them add ``$allowed_lang`` array:

.. code-block:: php

   $allowed_lang = array("en");

Dates
-----

.. _date_format:

Format
^^^^^^

You can adapt how dates are displayed with specifiers (see `strftime reference`_):

.. _strftime reference: https://www.php.net/strftime

.. code-block:: php

    $date_specifiers = "%Y-%m-%d %H:%M:%S (%Z)";

The date displayed in javascript should be configured with the dayjs format (see `<https://day.js.org/docs/en/display/format>`_):

.. code-block:: php

    $js_date_specifiers = "YYYY-MM-DD HH:mm:ss (Z)";

Timezone
^^^^^^^^

You can adapt the default timezone for displaying all the dates (see the `complete list of timezones <https://www.php.net/manual/en/timezones.php>`_):

.. code-block:: php

    $date_timezone = "UTC";

Graphics
--------

Logo
^^^^

You can change the default logo with your own. Set the path to your logo in ``$logo``:

.. code-block:: php

    $logo = "images/ltb-logo.png";

Background
^^^^^^^^^^

You can change the background image with your own. Set the path to image in ``$background_image``:

.. code-block:: php

     $background_image = "images/unsplash-space.jpeg";

Favicon
^^^^^^^

You can change the favicon with your own. Set the path to your favicon in ``$favicon``:

.. code-block:: php

    $favicon = "images/favicon.ico";

Custom CSS
^^^^^^^^^^

To easily customize CSS, you can use a separate CSS file:

.. code-block:: php

    $custom_css = "css/custom.css";

Footer 
^^^^^^

You can hide the footer bar:

.. code-block:: php

    $display_footer = false;

Password inputs
---------------

When testing or resetting a password, the browser will prompt to remember the password. You can disable this behavior in your browser for Service Desk page, but if you need to change this on server side, a trick is needed. Password inputs are converted into text inputs but value is kept hidden.

To enable this trick:

.. code-block:: php

   $fake_password_inputs = true;

Custom templates
^^^^^^^^^^^^^^^^

If you need to do more changes on the interface, you can create a custom templates directory
and override any of template file by copying it from ``templates/`` into the custom directory
and adapt it to your needs:

.. code-block:: php

    $custom_tpl_dir = "templates_custom/";

To define a custom template paramter, create a config parameter with ``tpl_`` prefix:

.. code-block:: php

    $tpl_mycustomparam = true;

And then use it in template:

.. code-block:: html

   <div>
   {if $mycustomparam}
   <p>Display this</p>
   {else}
   <p>Display that</p>
   {/if}

Debug
-----

You can turn on debug mode with ``$debug``:

.. code-block:: php

    $debug = true;

.. tip:: Debug messages will be printed in server logs.

You can adjust the debug level by using PHP predefined constants in ``$debug_level``:

.. code-block:: php

    $debug_level = E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED & ~E_WARNING;

This is also possible to enable Smarty debug, for web interface issues:

.. code-block:: php

   $smarty_debug = true;

.. tip:: Debug messages will appear on web interface.
   You will also have many more messages in error logs.

Smarty
------

You need to define where Smarty is installed:

.. code-block:: php

    define("SMARTY", "/usr/share/php/smarty3/Smarty.class.php");
