Twig

Snippets

Prevent returned HTML from being auto-escaped by Twig (source):

class MyParser {
    public function getHTML() {
         $rawString = '<a href="#">Hello World</a>'
         return new \Twig\Markup( $rawString, 'UTF-8' );
    }
}

Twig property search order SO answer #article - “{{ lang.test }} will try to invoke one of the following, in this order:”

• $lang->test

• $lang->test()

• $lang->getTest()

• $lang->isTest()

Twig property search order Twig docs #article - “For convenience's sake foo.bar does the following things on the PHP layer:”

• Search order:

  • check if foo is an array and bar a valid element;

  • if not, and if foo is an object, check that bar is a valid property;

  • if not, and if foo is an object, check that bar is a valid method (even if bar is the constructor - use __construct() instead);

  • if not, and if foo is an object, check that getBar is a valid method;

  • if not, and if foo is an object, check that isBar is a valid method;

  • if not, and if foo is an object, check that hasBar is a valid method;

  • if not, return a null value.

• foo['bar'] on the other hand only works with PHP arrays:

  • check if foo is an array and bar a valid element;

  • if not, return a null value.
