Template resolver


Template resolver allows to override templates, e.g. to override e-shop templates in project bundles. It is another way how to override templates beside the default Symfony overriding functionality (

Moreover, a web-site redesign is an another case when template resolver could come useful.

The idea behind the template resolver came from old eZ Publish 4 times, when it was possible to override any template using design combinations.

Template resolver sequentially goes through all configured bundles and designs (if specified), looking for the requested template. At last, if the requested template still hasn't been found, template resolver takes this template or default one if the requested template doesn't exist.

An override is activated by a template resolver configuration. You can configure:

  • list of bundles
  • list of designs (folders with templates)
  • default template

How to configure and use template resolver

Example 1: how to override templates

Let's say you have a project with a bundle src/Client/Bundle/WebsiteBundle, a site access website_de_de and you want to override  eZ Commerce bundle templates.

Step 1. Change your config_{env}.yml or parameters.yml

Template resolver is deactivated in the default configuration and has to be activated!

    # 1. Enable template resolver
    siso_tools.website_de_de.template_resolver.enabled: true    # true|false
	# 2. Define that your bundle is able to override templates
    siso_tools.website_de_de.template_resolver.bundles: [ClientWebsiteBundle]

Template resolver uses dynamic configuration of eZ Publish config resolver.

If you wand to have one configuration for all site accesses, change site access name to "default". E.g.:

siso_tools.default.template_resolver.enabled: false

Step 2. Create new templates in ClientWebsiteBundle

In order to override templates you have to reflect a structure of eZ Commerce vendor bundles, e.g.:  

Original template/vendor/silversolutions/silver.e-shop/src/Silversolutions/Bundle/EshopBundle/Resources/views/Catalog/catalog.html.twig
New template/src/Client/Bundle/WebsiteBundle/Resources/views/Catalog/catalog.html.twig

In this example the template from ClientWebsiteBundle overrides catalog.html.twig from SilversolutionsEshopBundle.

Next, you can create more and more templates using the folder structure of eZ Commerce bundle.

Example 2: how to override templates using designs

Design is just an additional folder in your Resources/views. Templates in the design folder have to reflect a structure of the bundle or bundles that you want to override.

Assume that you are preparing templates for a website redesign with a provisional name "redesign2015".

Step 1. Change your config_{env}.yml or parameters.yml

    siso_tools.website_de_de.template_resolver.enabled: true    # true|false
    siso_tools.website_de_de.template_resolver.bundles: [ClientWebsiteBundle]
	# Define design name
    siso_tools.website_de_de.template_resolver.designs: [redesign2015]


Step 2. Create new templates in ClientWebsiteBundle in the design folder

Create new folder Resources/views/designs/redesign2015 in your bundle and put new templates there:

Original template/vendor/silversolutions/silver.e-shop/src/Silversolutions/Bundle/EshopBundle/Resources/views/Catalog/catalog.html.twig
New template/src/Client/Bundle/WebsiteBundle/Resources/views/designs/redesign2015/Catalog/catalog.html.twig


In this example the template from the desing "redesign2015" in the ClientWebsiteBundle overrides catalog.html.twig from SilversolutionsEshopBundle.

Templates in design folders always have precedence over other templates.

If you have both redesign2015/Catalog/catalog.html.twig and Catalog/catalog.html.twig, the first one will win.

How to develop with TemplateResolver

Using in templates

To make a template overridable, you have to use a template filter st_resolve_template with its name.

{% extends "SilversolutionsEshopBundle::pagelayout.html.twig"|st_resolve_template %}
<div class="grid_4">
    {{ include('SilversolutionsEshopBundle:parts:address.html.twig'|st_resolve_template, {'class' : 'styled_list', 'address' : buyerAddress, 'displayEmail' : false, 'displayPhone' : false}) }}

It is not possible to include blocks with "use" tag because of specific implementation of this tag.

Because use statements are resolved independently of the context passed to the template, the template reference cannot be an expression.

Using in PHP code

Using in controllers

To make using of TemplateResolver in controllers easier, you can inherit your controller from Silversolutions\Bundle\EshopBundle\Controller\BaseController. In this case render and renderView method will get rendered template using TemplateResolver, i.e. overriden template.

use Silversolutions\Bundle\EshopBundle\Controller\BaseController;
class ExampleController extends BaseController
	public function showAction(Request $request)
	    return $this->render(
            	'param' => 'taram'

General using

Alternatively, you can inject TemplateResolver in your service (or take it from container) and resolve template there

/** @var TemplateResolverServiceInterface $templateResolverService */
$templateResolverService = $this->get('siso_tools.template_resolver');

$resolvedTemplate = $templateResolverService->resolve('YourBundle:redesign2015/Catalog/catalog.html.twig');


You can information about TemplateResolver configuration and overridden templates in the SilverSolutions tab of symfony web provider.



  • pagelayout.html.twig can not be resolved via template resolver
  • it is not possible to override templates included with the twig use operator.
  • it is not possible to use the template resolver in the configuration, therefore for overriding standard templates for e.g. full eZ template or templates defined for eZ flow, you need to override the configuration

                            #change the template name here
                            template: SilversolutionsEshopBundle::st_module.html.twig
                                Identifier\ContentType: [st_module]
                            #change the template name here
                            template: SilversolutionsEshopBundle::ses_productcatalog.html.twig
                                Identifier\ContentType: [ses_productcatalog]
