ZfcTwig is a module that integrates the Twig templating engine with Zend Framework 2.
- Add
"zf-commons/zfc-twig": "dev-master"to yourcomposer.jsonfile and runphp composer.phar update. - Add
ZfcTwigto yourconfig/application.config.phpfile under themoduleskey.
ZfcTwig has sane defaults out of the box but offers optional configuration via the zfctwig configuration key. For
detailed information on all available options see the module config file
class.
Extensions can be registered with Twig by adding the FQCN to the extensions configuration key which is exactly how the
ZfcTwig extension is registered.
// in module configuration or autoload override
return array(
'zfctwig' => array(
'extensions' => array(
// an extension that uses no key
'My\Custom\Extension',
// an extension with a key so that you can remove it from another module
'my_custom_extension' => 'My\Custom\Extension'
)
)
);By default, ZfcTwig uses a Twig_Loader_Chain so that loaders can be chained together. A convenient default is setup using
a filesystem loader with the path set to
module/Application/view which should work out of the box for most instances. If you wish to add additional loaders
to the chain you can register them by adding the service manager alias to the loaders configuration key.
// in module configuration or autoload override
return array(
'zfctwig' => array(
'loaders' => array(
'MyTwigFilesystemLoader'
)
)
);
// in some module
public function getServiceConfiguration()
{
return array(
'factories' => array(
'MyTwigFilesystemLoader' => function($sm) {
return new \Twig_Loader_Filesystem('my/custom/twig/path');
}
)
);
}Using ZF2 view helpers is supported through the ZfcTwig\Twig\FallbackFunction function.
{# Simple view helper echo #}
{{ docType() }}
{# Echo with additional methods #}
{{ headTitle('My Company').setSeparator('-') }}
{# Using a view helper without an echo #}
{% do headTitle().setSeparator('-') %}
{# Combining view helpers #}
{% set url = ( url('my/custom/route') ) %}Example .twig files for the skeleton application can be found in the examples folder.
ZF2 does not support multiple renderers with view helpers very well. As a workaround, ZfcTwig registers its own
HelperPluginManager that extends the default Zend\View\HelperPluginManager and adds the default as a peering manager.
This let's ZfcTwig register its own renderer with view helpers that require it and fallback to the default manager for
view helpers that do not require one.
As a caveat, you must register view helpers that require a renderer with ZfcTwig. An example can be seen in
config/module.config.php where the HelperConfig for the default navigation helpers is registered with ZfcTwig.
