Symfony2 twig Template engine

1. Basic grammar

Says something:{{}}

Does something:{%%}

Comment something:{# #}

{% extends "Appwebbundle::layout.html.twig"%} inherit template

2. Core concept:

Managing relationships between pages using the inheritance relationships of classes

If you want to access a resource file in a bundle, you need to copy the file to the/web directory, or the Linux/mac soft connection is mapped to the/web directory

Windows: >php app/console assets:install Web

Linux: >php app/console assets:install Web--symlink--relative

3. js CSS File Management

(1) Use a Css/js file directly: {{asset (' Xxx.js ')}}

(2) Register/define resource: {% javascripts%} {% stylesheets%}

# All JS files in the ' appwebbundle/resources/public/js/' directory will be output sequentially
{% block my_js%}    {% javascripts ' @AppWebBundle/resources/public/js/* '%}            {% endjavascripts%} { % endblock%}

And in the APP/CONFIG/CONFIG.YML configuration:

Assetic:    bundles:        [Appwebbundle]

(3) Common policies for sharing css/js files between pages
