I have a Symfony 5 website that uses Twig templates containing messages translated with
{% trans %}some.message.key{% endtrans %}
Is there a way to have Symfony output the message key itself instead of the translation? This can be helpful during development and translation work.
To demonstrate what I want, have a look at https://en.wikipedia.org/wiki/Main_Page?uselang=qqx, which shows such behavior in the MediaWiki software.

i've a problem with symfony project, in my Controller Company when I use edit function to modif some DATA with embedded form, symfony keep only 1 customer (first one) and what I was change and remove all other DATA.
I not understand why symfony do that.
Thank U for Ure help
Best regards
Try to use edit function in symfony with embedded form
You're using the wrong function to render the customer (and network and process) subforms, use form_row(customer) instead of form(customer):
{% for customer in form.customers %}
<h6 class="mt-5">Client
{{_key+1}}</h6>
{{ form_row(customer) }}{% endfor %}
I'm having a bit of trouble with Symfony twig translations, and I hope someone here can clarify.
Say I have a file /templates/general/hello_world.twig , with the contents:
{% trans with {
'%name%': name,
} %}
"Hello %name%"
{% endtrans %}
When I call bin/console translation:update --output-format=yaml fr --force , the output file translations/messages+intl-icu.fr.yaml now contains the contents:
'"Hello %name%"': '__"Hello %name%"'
This is only the case with Twig files - I have other files in translations where they are locale-suffixed, and those are properly translated into french. I'm not clear what has to happen in order to get the translation:update command to recognize that the original content is in English?
I'm not asking how to choose a locale based on the user request. I'm specifically wanting to generate missing translations for contents in my twig templates, and I'd love to have this command available to get me started. The command works a treat for translations actually in the /translations/ folder.
Update 2
// hello.twig
{% trans with {
'%name%': name,
} %}hello_world{% endtrans %}
//messages.en.yaml
hello_world: "Hello %name%"
I have a problem with flash messages in Symfony 4 and translation.
Translation of simple flash messages is working fine:
$this->addFlash('success', 'flashmessage.project_deleted');
But now I want to add some parameters to the flash messages and I have no idea how to handle it. I tried a lot, but nothing is working. I want to show in the flash messages the title of projects after f.e. removing. For example:
$this->addFlash('success', sprintf('flashmessage.project_deleted: %s', $project->getTitle()));
But the translation is not recognized, because the parameter is replaces before translation happens (I think so). And it should also be possible to have parameters in the middle of a string and not only at the end or at the beginning and ideally more than one parameter.
I'm using this in my Controller which extends AbstractController.
Does anybody has a solution for this?
Usually you would pass in the parameters to the translation, so your code snippet should probably look your first example and then in twig you would have something like this:
{% for message in app.flashes('success') %}
<div class="alert alert-success">
{{ message|trans({ 'title': project.title }) }}
</div>
{% endfor %}
The translation then should contain the parameter that is replaced:
flashmessage:
project_created: 'The project "%title%" was created successfully.'
project_deleted: 'You successfully deleted the project "%title%".'
...
Obviously the downside is that you have to dynamically pass in the variables which does not make much sense for flash messages, as not all of them will require these parameters. Also, as you already mentioned, when you deleted the project you will probably not have it available anymore in the template.
Instead I would recommend translating the message before passing it into the flash bag:
$this->addFlash(
'success',
$this->translator->translate(
'flashmessage.project_deleted',
[
'title' => $project->getTitle(),
]
)
);
This will require that you pass in the translator to your controller. You could either create your own base controller similar to Symfony's AbstractController for this and create something like a $this->trans()-method to make it easier to translate things inside your controller. Also, you will still have to make sure that $project->getTitle() will still return a value, so you probably want to call this before you actually delete the entry or have the data in memory.
When you do it this way, then you should not translate the flash messages in the template itself because they are already translated. This will still work because when Symfony tries to translate the already translated message, e.g. You successfully deleted the project "foo". then it will not find a translation and just print the original text instead, but you will get warnings in your logs about missing translations. The solution is to remove the |trans in your template (see first snippet).
A possible solution is to add another flash with serialized parameters.
Then, when you display your flash message, check if that extra flash exists and, if so, deserialize it and use it as argument.
Example follows.
In controller:
$this->addFlash('success', 'flashmessage.project_deleted');
$this->addFlash('_params', serialize(['%project%' => $project->getTitle()]));
In template:
{% flashMessage = app.session.flashbag.get('info') %}
{% if app.session.flashbag.has('_params') %}
{% set flashParams = app.session.flashbag.get('_params')|first|unserialize %}
{{ flashMessage|trans(flashParams) }}
{% else %}
{{ flashMessage|trans }}
{% endif %}
You need to create a Twig extension that defines an unserialize filter (or use a library that provides it)
Since Symfony 5.2 you can use the TranslatableMessage object to achieve this.
https://symfony.com/doc/current/translation.html#translatable-objects
use Symfony\Component\Translation\TranslatableMessage;
$this->addFlash(
'success',
new TranslatableMessage(
'flashmessage.project_deleted',
['%project%' => $project->getTitle()]
)
);
Then in your Twig template you only need to use {{ flashMessage|trans }}.
This works without injecting the Translator service, or messing about with anything in Twig.
Have a look at the ICU Message Format: https://symfony.com/doc/current/translation/message_format.html
Are there any ways for pluralizing a string in Symfony 3? For example: I have "Object" and I would like to get "Objects".
pluralization is a very complex topic and Symfony embraces it as part if the Translation Component:
Message pluralization is a tough topic as the rules can be quite complex.
So you basically would need to activate translations for your system and translate the needed strings using the transChoice() method of the translator service or the 'transchoice' tag / filter in your twig template.
To handle this, use the transChoice() method or the transchoice tag/filter in your template.
using the translator service
// the %count% placeholder is assigned to the second argument...
$translator->transChoice(
'There is one apple|There are %count% apples',
10
);
// ...but you can define more placeholders if needed
$translator->transChoice(
'Hurry up %name%! There is one apple left.|There are %count% apples left.',
10,
// no need to include %count% here; Symfony does that for you
array('%name%' => $user->getName())
);
twig tags
{% trans %}Hello %name%{% endtrans %}
{% transchoice count %}
{0} There are no apples|{1} There is one apple|]1,Inf[ There are %count% apples
{% endtranschoice %}
UPDATE
If you do not know the string beforehand you can use the internal Inflector Component, but be aware of the disclaimer and the fact that this would only work for strings in English:
This component is currently marked as internal. Do not use it in your own code. Breaking changes may be introduced in the next minor version of Symfony, or the component itself might even be removed completely.
An alternative would be to create your own inflector class, e.g. something like this and create a service from it.
I use the Symfony2.1 and have the default config.yml
Documentation said:
{# but static strings are never escaped #}
{{ '<h3>foo</h3>'|trans }}
But if I copy and paste it into the my empty template (without any additional autoescapes or another) I got the escaped string <h3>foo</h3>. What I do wrong?
Try it with the twig raw filter:
{{ '<h3>foo</h3>' | trans | raw }}
However, do not use the raw filter if you are processing any user input! It allows for cross-site-scripting attacks, according to the creators of Symfony. See this similar question for a secure but more tedious alternative.
Holding HTML stuff in translations is wrong, because translators usually break it. But if you really need it:
{% trans %}<h3>foo</h3>{% endtrans %}
