``attribute``
|
|
=============
|
|
|
|
.. warning::
|
|
|
|
The ``attribute`` filter is deprecated as of Twig 3.15. Use the
|
|
:ref:`dot operator <dot_operator>` that now accepts any expression
|
|
when wrapped with parenthesis.
|
|
|
|
Note that this filter will still be available in Twig 4.0 to allow a
|
|
smoother upgrade path.
|
|
|
|
The ``attribute`` function can be used to access a "dynamic" attribute of a
|
|
variable:
|
|
|
|
.. code-block:: twig
|
|
|
|
{{ attribute(object, method) }}
|
|
{{ attribute(object, method, arguments) }}
|
|
{{ attribute(array, item) }}
|
|
|
|
In addition, the ``defined`` test can check for the existence of a dynamic
|
|
attribute:
|
|
|
|
.. code-block:: twig
|
|
|
|
{{ attribute(object, method) is defined ? 'Method exists' : 'Method does not exist' }}
|
|
|
|
.. note::
|
|
|
|
The resolution algorithm is the same as the one used for the ``.``
|
|
operator, except that the item can be any valid expression.
|
|
|
