Twig (template engine)

src: i.ytimg.com

Branch is the template engine for the PHP programming language. The syntax comes from Jinja and Django templates. It is an open source product licensed under the BSD License and managed by Fabien Potencier. Early versions were made by Armin Ronacher. The Symfony2 PHP framework comes with bundle support for Twig as its default template engine.

Syntax

Twig defines three types of delimiter:

• {{...}} , to print variable content or expression evaluation results (for example: Twig template inherited with {{parent ()}} ).
• {#... #} , to add comments in the template. This comment is not included in the displayed page.
• {%... Ã,%} , to execute statements, such as for-loops.
  • {% set foo = 'bar' %} , to set.
  • {% if i is defined and i == 1 %} ... {% endif %} : condition.
  • {% for i in 0..10 %} ... {% endfor %} : count in a loop.

The apostrophe (') is the character of the runaway.

To create an iterative array:

Operator priority is, of fewer priorities:

Filters

The filter provides some treatment on the expression, when placed thereafter, separated by a pipe. As an example:

• capitalization : change the first letter of the string in capital.
• upper : change the whole string in capital.
• first : shows the first line of an array.
• length : returns the size of the variable.

Custom variables

• loop contains the current loop information. For example loop.index corresponds to the number of iterations that have already occurred.
• Global variables begin with underscores. As an example:
  • _route (the portion of the URL located after the domain)
  • _self (current filename)

  So, to route the page: {{path (app.request.attributes.get ('_ route'), app.request.attributes.get ('_ route_params') )}}

• CGI environment variables, such as {{app.request.server.get ('SERVER_NAME')}} .
