Using variables in templates:Įxample for the usage of variables and simple if condition in PHPTemplate:Įxample for the usage of variables and simple if condition in Twig: In most cases the ability to use custom PHP in template files lead to more complexity and a lack of clarity. Complex logic or further processing of variables should not be placed in the template files - I think everybody can remember a situation in which they inserted a view programmatically in a template or placed custom field on theme layer. Usually themers only have to care about the output of predefined variables or simple control structures ( if conditions or for loops that output lists of content). All examples mentioned in this blog post are based on the latest development state of the Drupal 8 Twig Sandbox. In order to explain these changes more clearly I want to compare the known PHPTemplate syntax with the new Twig template syntax. Watch out my blog for more updates on Drupal 8.Following up on the first blog post on Theming in Drupal 8 with Twig, this second part will cover Twig's syntax. Hope you will now be able to use Twig in Drupal 8. With easy reusability of the code, it also saves a lot of time and efforts. TwigExtension provides a great accessibility to the code which is often reused. Moving further, set the value from getImageAlt() function to a variable imageAlt inside placed in themes/my_theme/templates directory and then, render the variable imageAlt inside image alt tag. ![]() You can make a call to your TwigExtension directly inside template using “ $image_alt = trim(strip_tags($item_value)) Ĩ.) Applying Twig Extension to your twig template $item_value = $entity->get(‘field_item_title’)->getValue() ![]() $slide_image = $entity->get(‘field_image’)->getValue() * This function is used to return alt of an image Information provided inside module_ is used to be displayed on admin module page.Ĥ.) Create a service file inside your module as ‘module_’ĥ.) The TwigExtension.php contains the following code To start with it first, we need to create a module.ġ.) Create a new module inside: /modules/custom/ directory inside your drupal project.Ģ.) Our new module structure would look like this:ĭescription: ‘Provides Twig Extension that process the Alt tag of any given image.’ To get started, we need to create a module for TwigExtension. ![]() In the below example, we built an extension to render an image alt tag inside twig templates. ![]() Twig extension improves the experience with efficient coding techniques that involve lesser efforts and high flexibility. When you need to write a code often, try to reuse it rather than writing it from scratch every time.Ĭreating twig extension helps to separate the compiled code and the code at runtime execution. Outlined below are the advantages of using Twig Extensions:ĭrupal 8 views can increase the challenge in the case where you want to change, update or modify a value or need to process the content in the field. Twig extends in many ways such as tags, filters, operators, global variables, and functions. Twig extension provides more flexibility to process almost anything inside twig. Twig is a template framework and is a direct replacement for PHP template. Unlike Drupal 7, developers can’t use PHP functions directly now on. This has brought about a big change in the Drupal community. Drupal 8 introduces a great templating system “ Twig“ which is originating from Symfony, a PHP framework. ![]()
