BITRIX/TWIG

Module for rendering twig templates in bitrix framework

rus

Intro

Bitrix framework allows render content with third-party template engines, in particular, twig.

To implement this, bitrix required a global (sic!) array $arCustomTemplateEngines with next structure:

The templateExt key describes extensions of template files, and in function key of this array contains the global (sic!) function name, which implement the render of template.

Also, function must instantiate the template engine class and echo (yes, fucking echo, not return!) the result of rendering.

If you even feel headache because of this, wait a minute, this is not all.

Installation

You MUST use the composer autoloader in application init. You site MUST use utf-8 codepage.

To install module, simple run

Module will be stored in you vendor, register it classes and functions.

Configuration

Default configuration:

You may override or extend this configuration in bitrix/.settings.php file. The configuration key is twigRenderer. You config may be like this:

Usage

Simple place the file <component_template_name>.thml.twig (or <component_template_name>.twig) to you template folder, instead of <component_template_name>.php. All html-markup and twig functions / filters will be processed by twig engine. Module implement some custom functions to integrate template engine and bitrix framework (see below).

Custom twig variables functions

Global variables:

• $_SERVER — _SERVER;
• $_REQUEST — _REQUEST;
• $_GET — _GET;
• $_POST — _POST;
• $_FILES — _FILES;
• $_SESSION — _SESSION;
• $_COOKIE — _COOKIE;
• $_GLOBALS — _GLOBALS

Custom functions

• showError
• showMessage
• showNote
• bitrix_sessid_post
• bitrix_sessid_get
• getMessage
• include_component

All of this the same bitrix framework functions.

• _call_static($class, $method, $arguments = []) is the function to call static method from available class from framework kernel or autoloaded classes.

Variables in template

• result — $arResult in traditional template;
• params — $arParams in traditional template;
• lang — array with all loaded localized messages;
• template — instance of CBitrixComponentTemplate class;
• templateFolder — path to template folder;
• parentTemplateFolder — path to folder of parent template;

Events

The module call the onAfterTwigEngineInit event after initialization. You may use it for add you own functions / filters / extensions.

Tests

Now the test contains a minimal (example) test, because of bitrix framework not have a psr autoloader, service container and other framework-must-have thinks. Tests are possible only if you have installed framework, installed module and at least one template, renders by this module.

If you know how to make test for all of classes — you welcome.
