README

This project provides several Twig extensions for internal projects.

Installation

The preferred method of installation is via Composer. Run the following command to install the package and add it as a requirement to your project's composer.json:

composer require gubler/twig-extensions

Configuration

$twig = new Twig_Environment($loader, $options);
$twig->addExtension(new Gubler\Twig\Extension\FileIconClassExtension());
$twig->addExtension(new Gubler\Twig\Extension\FlashMessagesExtension());
$twig->addExtension(new Gubler\Twig\Extension\InstanceOfExtension());
$twig->addExtension(new Gubler\Twig\Extension\TableSortIconExtension());

For Symfony, register it in your services.yaml

services:
    gubler.twig_extension.file_icon_class:
        class: Gubler\Twig\Extension\FileIconClassExtension
        tags: [twig.extension]
    gubler.twig_extension.flash_messages:
        class: Gubler\Twig\Extension\FlashMessagesExtension
        tags: [twig.extension]
    gubler.twig_extension.instance_of:
        class: Gubler\Twig\Extension\InstanceOfExtension
        tags: [twig.extension]
    gubler.twig_extension.table_sort_icon:
        class: Gubler\Twig\Extension\TableSortIconExtension
        tags: [twig.extension]

You can also use the MimeTypeToIconClass library directly and inject it into your classes by registering it as a service:

services:
    Gubler\Twig\Extension\Lib\MimeTypeToIconClass: ~

Extensions

FileIconClass

This maps a mimetype to a FontAwesome file icon. This currently only supports the following filetypes:

• MS Word
• MS Excel
• MS PowerPoint
• PDF

All other files return a generic file icon.

{{ 'application/vnd.ms-excel'|fileIconClass }}

FlashMessages

This extension will iterate through the flashes of a given Session and convert them to Bootstrap 5 alerts.

This looks for the flash keys of success, warning, error, and notice.

Creating the flashes:

# In a Symfony controller:
$this->addFlash('success', 'This is a SUCCESS message');
$this->addFlash('error', 'This is an ERROR message');
$this->addFlash('warning', 'This is a WARNING message');
$this->addFlash('notice', 'This is a NOTICE message');

Rendering all flashes:

{{ flashMessages(app.session) }}

InstanceOf

This extension provides PHP's instanceof type operator as a Twig test.

{# date is \DateTime object #}
{{ date is instanceof("\\DateTime") ? 'ok' : 'bad' }}

TableSortIcon

This filter allows you to pass the column name, the sorted column name, and sort direction and get back a FontAwesome sorting icon classes.

<i class="{{ tableSortIcon('col1', 'col1', 'asc') }}"></i>
