I am trying to customize my symfony2 form choice_widget_expanded part, and trying to reference the base (standard) for the choice_widget_collapsed as per this instruction http://symfony.com/doc/current/cookbook/form/form_customization.html
But I get an error saying
Notice: Undefined index: choice_widget_collapsed in /var/www/beta/app/cache/dev/twig/ff/8a/9f46c90c543b16e78e981aeda67b.php line 19
Here is my twig code:
{% extends '::base.html.twig' %}
{% use 'form_div_layout.html.twig' with choice_widget_collapsed as base_choice_widget_collapsed %}
{% form_theme form _self %}
{% block choice_widget %}
{% spaceless %}
{% if expanded %}
{{ block('choice_widget_expanded') }}
{% else %}
{{ block('base_choice_widget_collapsed') }}
{% endif %}
{% endspaceless %}
{% endblock choice_widget %}
{% block choice_widget_expanded %}
{% spaceless %}
<div {{ block('widget_container_attributes') }}>
{% for child in form %}
{{ form_widget(child) }}
{{ form_label(child) }}
<br />
{% endfor %}
</div>
{% endspaceless %}
{% endblock choice_widget_expanded %}
{% block contents %}
This works for me on a fresh composer install of sf 2.2.1. You should not need to clear cache for template changes to register in the dev environment, but it's worth a shot. It could also be that you need to stop and start (not restart) apache/php5-fpm if using an opcode cache.
Since you're only modifying choice_widget_expanded all you really need is:
test.html.twig
{% extends '::base.html.twig' %}
{% form_theme form _self %}
{% block choice_widget_expanded %}
{% spaceless %}
<div {{ block('widget_container_attributes') }}>
{% for child in form %}
{{ form_widget(child) }}
{{ form_label(child) }}
<br />
{% endfor %}
</div>
{% endspaceless %}
{% endblock choice_widget_expanded %}
{% block body %}
<form>
{{ form_row(form.choice) }}
</form>
{% endblock %}
testAction
/**
* #Template()
*/
public function testAction()
{
$builder = $this->createFormBuilder();
$builder->add('choice', 'choice', array(
'choices'=>array('one'=>'one', 'two'=>'two', 'three'=>'three'),
'expanded'=>true
));
$form = $builder->getForm();
return array('form'=>$form->createView());
}
Ah.. I am sure Dylans answer is correct, but for the symfony2 version I use (2.0.16) the template for that form looks a little different, the choice_widget_expanded doesn't have it's own block but it is all in this
{% block choice_widget %}
{% spaceless %}
{% if expanded %}
<div {{ block('widget_container_attributes') }}>
{% for child in form %}
{{ form_widget(child) }}
{{ form_label(child) }}
<br /> {# <-------- Here's my addition to the template #}
{% endfor %}
</div>
{% else %}
<select {{ block('widget_attributes') }}{% if multiple %} multiple="multiple"{% endif %}>
{% if empty_value is not none %}
<option value="">{{ empty_value|trans }}</option>
{% endif %}
{% if preferred_choices|length > 0 %}
{% set options = preferred_choices %}
{{ block('widget_choice_options') }}
{% if choices|length > 0 and separator is not none %}
<option disabled="disabled">{{ separator }}</option>
{% endif %}
{% endif %}
{% set options = choices %}
{{ block('widget_choice_options') }}
</select>
{% endif %}
{% endspaceless %}
{% endblock choice_widget %}
I Should of course have pulled the code out of my own codebase instead of grabbing the latest version off of github, doh!

Here is an example of HTML code with some Django template tags:
{% extends "blog/base.html" %}
{% block title %}
Title
{% endblock %}
{% block content %}
<h1>Header</h1>
{% for post in posts %}
<h2>
<a href="{{ post.get_absolute_url }}">
{{ post.title }}
</a>
</h2>
<p class="date">
Published {{ post.publish }} by {{ post.author }}
</p>
{{ post.body }}
{% endfor %}
{% include "pagination.html" with page=posts %}
{% endblock %}
I want it to look like this. But VS Code reformats it to this view:
{% extends "blog/base.html" %} {% block title %} Title {% endblock %} {% block content %}
<h1>Header</h1>
{% for post in posts %}
<h2>
<a href="{{ post.get_absolute_url }}">
{{ post.title }}
</a>
</h2>
<p class="date">
Published {{ post.publish }} by {{ post.author }}
</p>
{{ post.body }} {% endfor %} {% include "pagination.html" with page=posts %} {% endblock %}
What should I do to prevent this ugly reformatting?
For example
I have two members in form object.
form_widget(form.icon)
form_widget(form.name)
I have changed 'choice_widget_expanded'
{% block choice_widget_expanded %}
{% spaceless %}
<table {{ block('widget_container_attributes') }}>
{% for child in form %}
<tr>
{{ form_widget(child) }}
{{ form_label(child) }}
</tr>
{% endfor %}
</table>
{% endspaceless %}
{% endblock choice_widget_expanded %}
However I would like to make it affect on {{form.icon}} only
is it possible ? how can I tell the object passed to this block is form.icon or form.name?
To override label block for choice_widget_expanded you can define your block and use it like in below
{% block choice_widget_expanded %}
{% spaceless %}
<table {{ block('widget_container_attributes') }}>
{% for child in form %}
<tr>
{{ form_widget(child) }}
{{ form_label_custom(child) }}
</tr>
{% endfor %}
</table>
{% endspaceless %}
{% endblock choice_widget_expanded %}
And for the custom label too form_label_custom
Note now for every choice field with expanded property (not all
fields) your new label will be in action
{% block form_label_custom %}
{% spaceless %}
{% if label is not sameas(false) %}
{% if not compound %}
{% set label_attr = label_attr|merge({'for': id}) %} /* you can skip this part for td */
{% endif %}
{% if required %}
{% set label_attr = label_attr|merge({'class': (label_attr.class|default('') ~ ' required')|trim}) %}
{% endif %}
{% if label is empty %}
{% set label = name|humanize %}
{% endif %}
<td {% for attrname, attrvalue in label_attr %} {{ attrname }}="{{ attrvalue }}"{% endfor %}>{{ label|trans({}, translation_domain) }}</td>
{% endif %}
{% endspaceless %}
{% endblock form_label_custom %}
Or even more you can define the custom form_widget_custom(child) block to override like
{% block form_widget_custom %}
{% spaceless %}
{% if compound %}
{{ block('form_widget_compound') }}
{% else %}
{{ block('form_widget_simple') }}
{% endif %}
{% endspaceless %}
{% endblock form_widget_custom %}
And now render your field
{{ form_widget_custom(form.icon) }}
How can I customize birthday type in Symfony2? There is no
{% block birthday_widget %}
in form_div_layout
The birthday form type gets rendered with the block choice_widget.
{% block choice_widget %}
{% spaceless %}
{% if expanded %}
{{ block('choice_widget_expanded') }}
{% else %}
{{ block('choice_widget_collapsed') }}
{% endif %}
{% endspaceless %}
{% endblock choice_widget %}
In the end, the block doing the output is named choice_widget_collapsed. Just make your changes in there.
{% block choice_widget_collapsed %}
{% spaceless %}
{% if required and empty_value is none and not empty_value_in_choices %}
{% set required = false %}
{% endif %}
<select {{ block('widget_attributes') }}{% if multiple %} multiple="multiple"{% endif %}>
{% if empty_value is not none %}
<option value=""{% if required and value is empty %} selected="selected"{% endif %}>{{ empty_value|trans({}, translation_domain) }}</option>
{% endif %}
{% if preferred_choices|length > 0 %}
{% set options = preferred_choices %}
{{ block('choice_widget_options') }}
{% if choices|length > 0 and separator is not none %}
<option disabled="disabled">{{ separator }}</option>
{% endif %}
{% endif %}
{% set options = choices %}
{{ block('choice_widget_options') }}
</select>
{% endspaceless %}
{% endblock choice_widget_collapsed %}
I'm trying to customize form_label in a template which already extends one template.
I'm using example in the Symfony2 documentation:
{% use 'form_div_layout.html.twig' with form_label as base_form_label %}
{% block form_label %}
{{ block('base_form_label') }}
{% if required %}
<span class="required" title="This field is required">*</span>
{% endif %}
{% endblock %}
but nothing change!
Can you help me?
Here is my solution.
In top of my form.html.twig file:
{% form_theme form with 'MyBundle:Activity:Form/fields.html.twig' %}
and now into fields.html.twig, I custom the form_label:
{% extends 'form_div_layout.html.twig' %}
{% block form_label %}
{% spaceless %}
{% if not compound %}
{% set label_attr = label_attr|merge({'for': id}) %}
{% endif %}
{% if required %}
{% set label_attr = label_attr|merge({'class': (label_attr.class|default('') ~ ' required')|trim}) %}
{% endif %}
{% if label is empty %}
{% set label = name|humanize %}
{% endif %}
<label{% for attrname, attrvalue in label_attr %} {{ attrname }}="{{ attrvalue }}"{% endfor %}>{{ label|trans({}, translation_domain) }}{% if attr.note is defined %} <span style="font: 11px normal; font-family: arial;">({{ attr.note }})</span>{% endif %}</label>
{% endspaceless %}
{% endblock form_label %}
I need set a class for widget container, but have no idea how Symfony passes attributes to "widget_container_attributes" block
Widget container template:
{% block form_widget %}
{% spaceless %}
<div {{ block('widget_container_attributes') }}>
{{ block('field_rows') }}
{{ form_rest(form) }}
</div>
{% endspaceless %}
{% endblock form_widget %}
Example result:
<div class="MY-CLASS">
<label class="required" for="page_title">Title</label>
<input type="text" value="Next subpage" maxlength="500" required="required" name="page[title]" id="page_title">
</div>
how can I do that?
try
{% extends 'form_div_layout.html.twig' %}
{% block field_rows %}
{% spaceless %}
{% for child in form %}
{{ form_row(child) }}
{% endfor %}
{% endspaceless %}
{% endblock field_rows %}
{% block field_row %}
{% spaceless %}
<div class="myclass">
{{ form_label(form, label|trans) }}
{{ form_widget(form) }}
{{ form_errors(form) }}
</div>
{% endspaceless %}
{% endblock field_row %}
