   1 ``include``
   2 ===========
   3
   4 .. versionadded:: 1.12
   5     The include function was added in Twig 1.12.
   6
   7 The ``include`` function returns the rendered content of a template:
   8
   9 .. code-block:: jinja
  10
  11     {{ include('template.html') }}
  12     {{ include(some_var) }}
  13
  14 Included templates have access to the variables of the active context.
  15
  16 If you are using the filesystem loader, the templates are looked for in the
  17 paths defined by it.
  18
  19 The context is passed by default to the template but you can also pass
  20 additional variables:
  21
  22 .. code-block:: jinja
  23
  24     {# template.html will have access to the variables from the current context and the additional ones provided #}
  25     {{ include('template.html', {foo: 'bar'}) }}
  26
  27 You can disable access to the context by setting ``with_context`` to
  28 ``false``:
  29
  30 .. code-block:: jinja
  31
  32     {# only the foo variable will be accessible #}
  33     {{ include('template.html', {foo: 'bar'}, with_context = false) }}
  34
  35 .. code-block:: jinja
  36
  37     {# no variables will be accessible #}
  38     {{ include('template.html', with_context = false) }}
  39
  40 And if the expression evaluates to a ``Twig_Template`` object, Twig will use it
  41 directly::
  42
  43     // {{ include(template) }}
  44
  45     $template = $twig->loadTemplate('some_template.twig');
  46
  47     $twig->loadTemplate('template.twig')->display(array('template' => $template));
  48
  49 When you set the ``ignore_missing`` flag, Twig will return an empty string if
  50 the template does not exist:
  51
  52 .. code-block:: jinja
  53
  54     {{ include('sidebar.html', ignore_missing = true) }}
  55
  56 You can also provide a list of templates that are checked for existence before
  57 inclusion. The first template that exists will be rendered:
  58
  59 .. code-block:: jinja
  60
  61     {{ include(['page_detailed.html', 'page.html']) }}
  62
  63 If ``ignore_missing`` is set, it will fall back to rendering nothing if none
  64 of the templates exist, otherwise it will throw an exception.
  65
  66 When including a template created by an end user, you should consider
  67 sandboxing it:
  68
  69 .. code-block:: jinja
  70
  71     {{ include('page.html', sandboxed = true) }}
