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 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:
https://stackoverflow.com/a/10817495/5258172
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 was wondering if someone can tell me how to hide the action links from the list view base on a status column.
More details: I have a list view in which shows a list of items, In this list I have column named status. For each record in this list in which status is set to close, I would like to hide the edit/delete and other custom actions links from the list. Is this doable? if so, how?
Thanks
A possible solution is to override just the item_actions Twig block in the list.html.twig template used by that entity. In practice, if the entity is called Order, a template like this should work:
{# app/Resources/views/easy_admin/Order/list.html.twig #}
{% extends '#EasyAdmin/default/list.html.twig' %}
{% block item_actions %}
{% if item.status != 'close' %}
{{ parent() }}
{% endif %}
{% endblock item_actions %}
I was trying to learn about framework and Ill be starting under "Symfony", then i got this problem, I create a
{{ form_widget(form.type) }}
equivalent to
<input type="text" class="type" id="type"/>
this element "input" have a value that given by a tab or menu if i click on it, example jumping.how do i compare it to a text using "Symfony" if statement like the logic below.
{% if jumping == "text" %}
//it will do something
{% endif %}
as explained nicely in the symfony docs here you need to use the form.vars.value to get the input field's value
so for someting like {{ form_widget(form.name) }} you would access the values by doing {{ form.vars.value.name }}
in your case it would be
{% if form.vars.value.name == "text" %}
//do something
{% endif %}
I have a problem which I cannot solve. How shall I approach the following: I have a choice field with 4 different entries, which I am rendering perfectly in a select form (twig). However, I would like to show the 4 entries as 4 separate buttons. How do I change the input type of those 4? Or do I have to do anything totally different?
Thanks for your help

edit (new following question):
Alexandru, thanks for your help. That was very helpful.
I added in the fields.html.twig the following:
{% block _appbundle_action_Style_widget -%}
{% for child in form %}
<input type="button" {{ block('widget_attributes') }}{% if value is defined %} value="{{ value }}"{% endif %}{% if checked %} checked="checked"{% endif %} />
{% endfor %}
{%- endblock _appbundle_action_Style_widget %}
However, when I render it it tells me that there is an array to string conversion, which somehow does not work. When I delete the widget attributes, value, and checked parts, the buttons are getting rendered without those then.
You have a few options to choose from:
You can create a new field type, let's call it "button_group", that will extend the "choice" type and write the custom Twig for it, something like this:
https://github.com/symfony/symfony/blob/2.7/src/Symfony/Bridge/Twig/Resources/views/Form/bootstrap_3_layout.html.twig#L95
You can use the "choice" field type with the option: expanded => true. And create a custom form template for it only for the form you need it in:
http://symfony.com/doc/current/cookbook/form/form_customization.html#what-are-form-themes
Ok I solved my problem. In order to access the value variable I have to use the following {{ child.vars.value }}. With this I can now take the variable and put it into the value tag.
Thanks for your help.
I have a Customer object, which has many Emails.
I'm building a form for my customer, and I've added his emails as a collection. In my template, I render the emails portion like this:
<h4>Emails</h4>
{% for email in form.emails %}
<li>
{{ form_row(email.addr) }}
{{ form_row(email.isPrimary) }}
</li>
{% endfor %}
...
{{ form_rest(form) }}
This works fine, except if the customer has no emails. Then, form_rest() renders the label 'emails' at the bottom of my template.
Why does this only get rendered when form.emails is empty? How can I customize it? (Note I've already customized my label rendering for other form elements, and I don't want it to be the same for these 'collection labels'.)
I usually solved this problem this way:
{% for email in form.emails %}
{# ... #}
{% else %}
{{ form_widget(form.emails) }}
{% endfor %}
Unless someone suggests a better way of doing this.
