With Silex (the PHP micro framework), it's possible to give names to existing controllers, so that we can easily generate urls to them later. Example:
$app->get('/gallery', function () {...})
->bind('gallery');
// Later on, in a template
{{ path('gallery') }}
I think this is really useful and I can't live without it.
But is it possible to register a route to an external website ? Say I'd like to generate urls to a google search, kind of
{{ path('google', {'search':'symfony'}) }}
// Would render to http://google.com/search?q=symfony
I take any idea :) Thx for your help !
path() is a Twig Extension for routing. Routing is to route an incoming URL to a controller action.
You can, however, create your own twig extension if you want a helper to easily create those standard outgoing URLs.
Take a look at: http://symfony.com/doc/current/cookbook/templating/twig_extension.html
You could then create an extension that turns {{ google('search string') }} into a URL. Only the imagination is your boundary.

Hi I'm coming for a very simple question (I think) but i didn't found the answer or a similar case.
I'm using symfony 3 and trying to build a second menu for my administration pannel.
However, I have a problem about how I have to declare the relative url in my "href", For my main menu i used to do like this
{{ url ( 'admin' ) }}
and it worked. The fact is that now I have subfolders and many levels in my url.
The url i try to reach is myapp/admin/gameadmin, this url work when I'm going on it but when i try to put it in 'href' I have an error message which says that the route is not working.
i declared it like that ->
{{ url(admin/gameadmin) }}
I tried with different character -> admin:gameadmin, admin\gameadmin ... etc and with path instead of url i don't know if it's not the good way to declare it or if I have a problem with my controllers.
In my bundle it's organised like that :
->Controllers(folder)
->admin(folder) (You can also find my main controllers on this level)
->admingamecontroller (Where the page I try to reach is routed)
I hope i gave you all the informations, thank you for your help and sorry for my english !
The url parameter is not the the url per se (ie: admin/gameadmin), this is the route name, defined in your routing.yaml file, or in your controller annotation.
If your action is something like this:
/**
* #Route("/admin/gameadmin", name="gameadmin")
*/
public function gameAdminAction()
{
...
}
Then, to generate the route, you have to do this:
{{ url('gameadmin') }}
By doing this, all the links on your website will be up to date if you change the gameadmin url, as long as you don't change the route name.
I suggest you to read this documentation on the Symfony website: https://symfony.com/doc/current/bundles/SensioFrameworkExtraBundle/annotations/routing.html
Edit: As pointed by user254319, if you're not using annotations, you'll have to edit your routing.yaml config file.
gameadmin:
path: /admin/gameadmin
controller: App\Controller\Admin\AdminGameController::gameadminAction
The route name is the yaml key: gameadmin.

I am creating a Symfony 4 web app that supports multiple languages. The routing is done, so I can have /en/suchpage or /de/suchpage. I am now looking for a way to link to "suchpage" using the right locale.
Routing looks as follows:
suchpage:
path: /{_locale}/suchpage/
controller: App\Controller\SimplePageController::such
requirements:
maw: '%app.locales%'
defaults:
_locale: '%locale%'
I am using Twig, and it is from Twig templates that I need to be able to link to the right version of a page. This "works":
{{ path('suchpage', {'_locale': app.request.locale}) }}
It has two issues though:
I do not want to be repeating this all over the place. Something like {{ page('suchpage') }} would be much better. Does a function like this exist? Can path() be made to behave like this?
This fails if the locale was not specified in the request, as can happen, since it is not required on all pages (since some have a default).
There is a maintened bundle, JMSI18nRoutingBundle, to achieve what you need.
composer require jms/i18n-routing-bundle

I am working on the front end of a Laravel project and I can change all the values in the view templates. I can probably modify other files as well, but, as I don't yet grok Laravel Blade fully, and I have a time constraint, I'd prefer not to make life harder for myself.
What I want to do is output some data related to the current route, and retrieve and parse some data from the Resources/lang/values.php file. Can I do this within the view without inserting a bunch of messy php? Is this a stupid thing to do? Is their a best practice for this?
Thanks in advance.
Use __() or trans() helpers or #lang Blade directive to work with language files:
{{ __('values.some_string_from_values_language_files') }}
Or:
#lang('values.some_string_from_values_language_files')
These helpers will work only if values.php is in:
resources/lang/en/values.php
resources/lang/fr/values.php
....
An answer to your question about best practices is no, you shouldn't reinvent the wheel and keep language files in a standard directory.
To get current route data, use Route facade and these methods:
$route = Route::current();
$name = Route::currentRouteName();
$action = Route::currentRouteAction();

I'm trying to call a controller from a twig extention.
I do not want to call the controller as a service since I'd lose all the fancy shortcuts.
Want I want to achieve is to call the controller like twig do it when you do :
{{ render(controller(
'AppBundle:Article:recentArticles',
{ 'max': 3 }
)) }}
I looked at the sourcecode of the "render" and tried to find the "controller" twig's functions, but I did not managed to understand how to do.
From now I achieved an unsatisfying but functionnal code :
In my twig extention :
return $environment->render('FooBundle:TwigExtension/CmsExtension:cmsRenderHook.html.twig', [
'hook' => $hook,
]);
In the CmsExtension:cmsRenderHook.html.twig template :
{{ render(controller(hook.stringControllerAction, hook.arrayParameters)) }}
I think (maybe wrongly) that it would be faster to call it without the template step.
EDIT : I finally successed to code this :
$environment->getExtension('Symfony\Bridge\Twig\Extension\HttpKernelExtension')->renderFragment(
$environment->getExtension('Symfony\Bridge\Twig\Extension\HttpKernelExtension')->controller(
$hook['action'],
$hook['jsonParameters']
)
);
(I did a grep in twig's cache and reproduced it compiled version).
my only concern is about referring to Symfony\Bridge\Twig\Extension\HttpKernelExtension, i'd rather let twig handle this choice, but I can't find out how.
I have two questions:
- do you think that Symfony\Bridge\Twig\Extension\HttpKernelExtension is stable enought to refere explicitly to it?
- if not how would you do to let twig handle it?
You could also get the Twig_SimpleFunction from the Twig_Environment:
$renderFunction = $environment->getFunction('render'); // get the env via initRuntime(..) in your extension
$callable = $renderFunction->getCallable();
However, I would not recommend relying on Twig internals. You should probably extract the functionality into a service.
Hi I have a hyperlink from a page:
<h3>hitest</h3>
the route:
Route::get('hitest', function(){ return 'hitest message';});
There is an error:
No query results for model [App\User2].
hyper link is from a page with this url
/userpage/1
the 1 is a model object.
Shouldn't the hyperlink route to /hitest ?
Please see my other post: Strange behavior with routing and hypertext.
I'm new at web development. Is there configurations for routing? The app is hosted (not local).
As bytesarelife already mentioned, you can use the url()-function, like so:
{{ url('your/url/') }}
A better way in terms of maintainability would be to give your routes names, so you would not have to replace every url in every template once you want to change it. You can do so, by adding the name in your routes:
Route::get('hitest', function(){ return 'hitest message';})->name('getHittest');
And then you can use the route function in your view:
{{ route('getHittest') }}
