I have a filter bar that let me search some results within my database.
I have a flash message that shows how many results are found when I enter a word inside it.
this is my controller
if ($filter != '') {
$this->get('session')->getFlashBag()->add('info', 'worked!');
}
and this is in my template
{% for message in app.session.flashbag.get('info') %}
{{ message }}
{% endfor %}
so when i research things actually, whether I have 1 result or more it doesn't change my sentence.
résultats is still written with an s as it is hard coded. How can I create something that will allow me to pluralize and singularize a word in my template? Should I go directly in the controller for that ?
EDIT
I used this method directly in the template but I don't think it is a "good practice" one. Any help for making that better?
{{ results.getTotalItemCount }}
{% if results.getTotalItemCount <= 1 %}
{{ 'this.is.your.result'|trans({ '%count%': results.getTotalItemCount}) }}
{% else %}
{{ 'this.is.your.results'|trans({ '%count%': results.getTotalItemCount}) }}
{% endif %}
in translation
this:
is:
your.result: "résultat"
your.results: "résultats"
You should maybe check pluralization in translations here, you can use transChoice() method, it is explained here how to use it.
Here you can see how to use it in twig:

Edit:
your answer in question can be done like this:
this:
is:
your.result: "1 résultat|%count% résultats"
and then in your twig:
{{ 'this.is.your.result'|transchoice(results.getTotalItemCount) }}

I send from Symfony object which contains at-sign # in variable.
Object name is invoice and with {{ dump(invoice) }} in twig template I see object and parameter with path:
invoice[0].banSpojDod#showAs
But I dont know how to get value of this banSpojDod#showAs because there is at-sign #.
Could you help me someone please?
You could try with The attribute function can be used to access a "dynamic" attribute of a variable:
{{ attribute(invoice[0], 'banSpojDod#showAs') }}
Hope this help
Ok thanks. Problem was that I used it in loop, and some parameters not exists. I needed to add exist conditions. So my final code works:
{% for f in invoice %}
{% if attribute(f,'banSpojDod#showAs') is defined %}
{{ attribute(f,'banSpojDod#showAs') }}
{% endif %}
{% endfor %}
I am trying to display the "label" (ie, value displayed to user) of a choice field in my twig template. I'm using Symfony 2.3. I just need the label associated with the actual current value of the field.
I finally figured out a way to do it that requires looping through every choice option, but am now wondering if there is a more efficient way? Here is my working code:
{% for choice in form.myfield.vars.choices %}
{% if choice.value == form.myfield.vars.value %}
{{ choice.label }}
{% endif %}
{% endfor %}
I'm looking for something like this (non-working code):
{{ form.myfield.vars.choices[form.myfield.vars.value].label }}
Is there a more efficient way, or is my solution the best possible?
I have a one to one relation between Player and Image. I have also this line in my controller:
var_dump($players[0]->getLinkedImage1()->getName());
It shows the name of an image correctly.
And I have also this line in the template:
{% for players in player %}
{{ player.age }}
{{ player.linkedImage1.name }}
{% endfor %}
but I get this error:
Impossible to access an attribute ("name") on a NULL variable ("")
I expected the last line shown the same name as in the controller.
EDIT: finally I found out that the property was public, that was the reason. Anway I still understand it..
My bad !
Look your for loop..
Try
{% for player in players %}
How did you write the property ? linkedImage1?
If you wrote something like linked_image_1 or linkedImage_1 you should call
{{ player.linked_image_1 }}
or
{{ player.linkedImage_1 }}
then twig will call the related getter according to : http://api.symfony.com/2.4/Symfony/Component/DependencyInjection/Container.html#method_camelize
If its a virtual getter you can directly access with :
{{ player.getLinkedImage1().name }}
or {{ player.getLinkedImage1().getName() }} `
You should try
{{ player.getLinkedImage1().getName() }}
I want to use an filter in an if condition in Twig. The reason for this is a Symfony2 attribute, which I can't compare directly, I have to change it beforehand. I have started with this code:
{% if app.request.attributes.get('_controller')|split('::')|first == 'some\controller\name' %}
do something
{% endif %}
Unfortunately this does not function. So I thought I would use set before the comparison:
{% set controller = app.request.attributes.get('_controller')|split('::')|first %}
{% if controller == 'some\controller\name' %}
do something
{% endif %}
{{ controller }} {# would print 'some\controller\name' #}
Guess what? "do something" is not printed, even if the variable controller now exists and has the value I compare it with. What am I doing wrong?
Ok I tested it, Twig has a strange behavior. "\" is escaped or something like this.
I extended my twig environement with the var_dump function, check this:
{{ var_dump("Sybio\Bundle\WebsiteBundle\Controller\MainController") }}
//string(48) "SybioBundleWebsiteBundleControllerMainController"
{{ var_dump(app.request.attributes.get('_controller')|split('::')|first) }}
// string(52) "Sybio\Bundle\WebsiteBundle\Controller\MainController"
{{ var_dump("Sybio\\Bundle\\WebsiteBundle\\Controller\\MainController") }}
// string(52) "Sybio\Bundle\WebsiteBundle\Controller\MainController"
That's why your test is always false.
You need to double the backslashes of your compared string...
{% if app.request.attributes.get('_controller')|split('::')|first == 'some\\controller\\name' %}
do something
{% endif %}
imaging that i have a object and which can be called in a twig template like this:
{{ object1.object2.object3.property3A }}
well, it will show me the content if we use php to write is :
$object1->getObject2()->getObject3()->getProperty3A();
My question is if i have a string ,
$refString="object1.object2.object3.property3A";
and then it is passed to twig, how could i get the property3A? For my experience, we can do this in php like this:
$refString="object1->getObject2()->getObject3()->getProperty3A()";
echo $$refString;
But i do not know how to make it work in twig.
I didn't tested this, but i think it schould do the trick.
{#
recursively reading attributes from an object
! object1 must be available !
theValue is the value of property3A
#}
{% for key in "object1.object2.object3.property3A"|split('.') %}
{% if not loop.first %}{# skip the 'object1' part #}
{% set theValue = attribute(theValue|default(object1), key) %}
{% endif %}
{% endfor %}
I don't think there is a "shortcut" to do this in twig. If you can't find a simple way to do this, you can write you own extension, that would convert a STRING_TYPE to a VAR_TYPE.
Twig internals might put you on the right track. This is an example of what is feasable with twig extension and might inspire you.
I ran into a similar situation. This answer will only work if the object you need is available to the template and you know the name of it with a string.
In this case, you can access the object using Twig's Global Variable _context:
{% set object1 = _context['object1'] %}
And then access the methods and variables of the object as normal:
{{ object1.object2.object3.property3A }}
