The Debug ExtensionΒΆ


The debug extension (Twig_Extensions_Extension_Debug) coming from the Twig-extensions package is deprecated as of Twig 1.5. Use the Twig built-in dump function from the Twig_Extension_Debug extension instead.

The debug extension provides a debug tag that can be used to output the content of the current context:

{% debug %}

This is really useful when a template does not work as expected. You can also output a specific variable or an expression:

{% debug items %}

{% debug post.body %}


The debug tag only works when the debug environment option is set to true.
