Grav CMS: how to access form labels from template (checkboxes) - forms

With a form including a checkboxes field and an email or save action set up, is there a way to access the individual checkboxes' labels from within the template?
So far, I've only been able to access the ids and values of the checkboxes, like so:
{%- for field in form.fields -%}
{%- set value = form.value(field.name) -%}
{%- if field.type == "checkboxes" -%}
{%- for key in in value|keys -%}
{{- key ~ ": " ~ value[key] ~ "\r\n" -}}
{%- endfor -%}
{%- endif -%}
{%- endfor -%}

To get the default values and labels of a checkboxes field, you could try the following:
The field definition of the form:
fields:
...
myfield:
type: checkboxes
label: A 'checkboxes' field
default:
option1: true
option2: false
options:
option1: Option 1
option2: Option 2
use: keys
Inside Twig template:
{% for field in form.fields %}
{% if field.type == 'checkboxes' %}
{% for key, label in field.options %}
<p>{{ label ~ ': ' ~ (field.default[key] ? 'true' : 'false') }}</p>
{% endfor %}
{% endif %}
{% endfor %}

How can I put the asterisk of my required field on my label? (Symfony form)

I am working on Symfony 3 and I have some trouble with my form.
When I create a Symfony form with a field not required, here is my code :
I create the form :
$form = $this->createFormBuilder()
->add('prenom' TextType::class, array(
'label' => 'Votre prénom',
'required' => false
)
->getForm();
Here is the code in my view for this field:
{{ form_label(form.prenom) }}
{{ form_errors(form.prenom) }}
{{ form_widget(form.prenom) }}
And this is the HTML I have :
<label class="control-label" for="contact_prenom">Votre prénom</label>
<input type="text" id="contact_prenom" name="contact[prenom]" class="form-control"/>
Now if I do the same without the 'require' => false on my FormBuilder, here is the HTML I get:
<label class="control-label required" for="contact_prenom">Votre prénom</label>
<sup class="required" title="Champ obligatoire">
<i class="fa fa-asterisk"></i>
</sup>
<input type="text" id="contact_prenom" name="contact[prenom]" required="required" class="form-control" />
Is it possible to control the "sup" tag so the asterisk * can be with my label?
I guess I can do it with jQuery, but I'd like to know if it is possible to do it on my form builder or in Twig?
In the doc there is a specific section here http://symfony.com/doc/current/form/form_customization.html#adding-a-required-asterisk-to-field-labels
You can even do with CSS only
label.required:before {
content: "* ";
}
As of Symfony 5.1 you can do the following
->add('name', TextType::class, [
'label' => 'Name <span class="badge badge-danger badge-pill">Required</span>',
'label_html' => true
])
The label_html (bool) property will allow HTML to be injected into the label directly and render on the form output.
Documentation - https://symfony.com/doc/current/reference/forms/types/form.html#label-html
Yes, you could override the twig template or the block that symfony uses to render your widget, have a look at:
http://symfony.com/doc/current/templating/overriding.html
In your case, you're looking for
vendor/symfony/symfony/src/Symfony/Bridge/Twig/Resources/views/Form/form_div_layout.html.twig
And this would be the block you want to override:
{%- block form_label -%}
{% if label is not same as(false) -%}
{% 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 -%}
{%- if label_format is not empty -%}
{% set label = label_format|replace({
'%name%': name,
'%id%': id,
}) %}
{%- else -%}
{% set label = name|humanize %}
{%- endif -%}
{%- endif -%}
<label{% if label_attr %}{% with { attr: label_attr } %}{{ block('attributes') }}{% endwith %}{% endif %}>{{ translation_domain is same as(false) ? label : label|trans({}, translation_domain) }}</label>
{%- endif -%}
{%- endblock form_label -%}

Html in label choice form

In choiceType field I have parameter - choice label
'choice_label' => function ($pay, $key, $index) {
return "<b>".$pay->getName()."</b><br />";
},
And render function of fields in twig:
{{form_widget(field)}}
{{form_errors(field)}}
Of course I want to render getName in bold characters,
I have try with twig autoescape and {{form_widget(field)|raw}} - without success
You have to custom the choice_label form in a custom theme (ex : radioHTML.html.twig) => I just add |raw to the label text
{%- block form_label -%}
{% if label is not same as(false) -%}
{% 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 -%}
{%- if label_format is not empty -%}
{% set label = label_format|replace({
'%name%': name,
'%id%': id,
}) %}
{%- else -%}
{% set label = name|humanize %}
{%- endif -%}
{%- endif -%}
<{{ element|default('label') }}{% if label_attr %}{% with { attr: label_attr } %}{{ block('attributes') }}{% endwith %}{% endif %}>
{%- if translation_domain is same as(false) -%}
{{- label|raw -}}
{%- else -%}
{{- label|trans({}, translation_domain)|raw -}}
{%- endif -%}
</{{ element|default('label') }}>
{%- endif -%}
{%- endblock form_label -%}
Your form type just return html string in the choice_label option :
$builder->add('fieldName', EntityType::class, array(
'required' => true,
'class' => 'AppBundle\EntityName',
'choice_label' => function (EntityName $entity) {
$html = '<div>';
$html .= $entity->getName();
$html .= '</div>';
return $html;
},
'data' => null,
'multiple' => false,
'expanded' => true)
And then use it for your specific field like that in your twig TPL :
{% form_theme from.fieldNalme 'form/radioHTML.html.twig' %}

Passing a macro argument to an if == test in jinja?

I'm using Tarbell to publish a formatted version of an inventory spreadsheet. Every row has a category, so I can do something like this:
<h2>Power Tools</h2>
{% for row in inventory %}
{% if row.Category == "powertools" %}
<b>{{ row.Display_Name|e }}</b> <br />
{% endif %}
{% endfor %}
<h2>A/V Gear</h2>
{% for row in inventory %}
{% if row.Category == "av" %}
<b>{{ row.Display_Name|e }}</b><br />
{% endif %}
{% endfor %}
To get a list of all the power tools followed by a list of A/V gear. I'd like to move that into a macro that I can call with a couple of arguments. I've got this:
{% macro list(cat, title='') -%}
<p>Category: {{ cat }}; Header: {{ title }}</p>
{% for row in inventory %}
{% if row.Category == "{{ cat }}" %}
<b>{{ row.Display_Name|e }}</b><br />
{% endif %}
{% endfor %}
{%- endmacro %}
When I call it with:
{{ list('av', title='Cameras and Audio Recorders')}}
{{ list('powertools', title='Power Tools')}}
I see "Category: powertools; Header: Power Tools" and "Category: av; Header: Cameras and Audio Recorders" as expected, so I know the macro can hear me, but the list itself doesn't show up. Can I use a macro argument in a comparison test? How?
There is no need for variable interpolation syntax inside of a block - you can just refer to the variable by name as you would in Python:
{# Do this #}
{% if row.Category == cat %}
{# Instead of this #}
{% if row.Category == "{{ cat }}" %}

Symfony2 twig forms

Symfony2 uses some twig templates when rendering forms.
In particular, in order to render the choice form field collapsed, symfony2 uses the following snippet of code (from form_div_layout.html.twig):
{%- block choice_widget_collapsed -%}
{%- if required and placeholder is none and not placeholder_in_choices and not multiple -%}
{% set required = false %}
{%- endif -%}
<select {{ block('widget_attributes') }}{% if multiple %} multiple="multiple"{% endif %}>
{%- if placeholder is not none -%}
<option value=""{% if required and value is empty %} selected="selected"{% endif %}>{{ placeholder != '' ? placeholder|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>
{%- endblock choice_widget_collapsed -%}
In my application, I want to create a new form type, that extends the default collapsed choice type, but where choice list has custom formatting.
In other words, for my form field type, named places_widget, extending choice_widget_collapsed block but redefining choice_widget_options.
I already tried:
/* My first attempt */
{%- block places_widget -%}
{% block choice_widget_options %}
{{ block('choice_places_widget_options') }}
{% endblock choice_widget_options %}
{{ block('choice_widget_collapsed') }}
{%- endblock places_widget -%}
/* My other attempt */
{%- block places_widget -%}
{{ block('choice_widget_collapsed', { 'choice_widget_options' => choice_places_widget_options }) }}
{%- endblock places_widget -%}
/* together with */
{%- block choice_places_widget_options %}
// code here
{%- endblock choice_places_widget_options -%}
None of the two solutions is working, and actually I have the feeling I am doing things in the wrong way.
Does anyone have any idea on how to achieve the goal?
Thank you in advance
Forms can be customized using themes (see the doc here: http://symfony.com/doc/current/cookbook/form/form_customization.html#form-theming-in-twig)
In your case, it seems you need to load your own theme with:
{% form_theme form _self %}
Note that you could externalize these blocks in another file (refer to http://symfony.com/doc/current/cookbook/form/form_customization.html#method-2-inside-a-separate-template to see how to do that)

Symfony2: add class to every select

I'm trying to customize Symfony2 form rendering to add a class to every select that is generated.
I thought that having a custom form_div_layout.html.twig with:
{% block choice_widget_collapsed %}
{% spaceless %}
<select class='myclass' {{ block('widget_attributes') }}{% if multiple %} multiple="multiple"{% endif %}>
{% if empty_value is not none %}
<option value="">{{ 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 %}
and using it with
{% form_theme form 'YOPYourOwnPoetBundle:Form:form_div_layout.html.twig' %}
would do the trick.
However, the class 'myclass' isn't added to the select.
What am I doing wrong?
You should first make sure the theme file you're trying to use has the same name as the name you're using in the form_theme expression and that the file really is there. I can't remember off top of my head whether Twig throws an exception or not in case these do not match.
In addition, you might be accidentally passing a class attribute either when building a form or rendering it. What happens is that your element now has two class attributes.
A workaround is to actually add your new class to the collection of existing ones.
{% block choice_widget_collapsed %}
{% spaceless %}
{% set label_attr = label_attr|merge({class: label_attr.class|default('') ~ ' required'}) %}
{% set attr = attr|merge({class: (attr.class|default('') ~ ' myclass')|trim}) %}
<select {{ block('widget_attributes') }}{% if multiple %} multiple="multiple"{% endif %}>
{# ... #}
</select>
{% endspaceless %}
{% endblock choice_widget_collapsed %}
This allows you to add any optional class you might need for specific elements later on.
EDIT
Looking at the Sf2 Github repsitory it seems that the theme file has been recently changed. In versions 2.0.* you should be overriding choice_widget, in versions 2.1.* the correct block is choice_widget_collapsed.
I suppose you should either change the form theme line to:
{% form_theme form 'YOPYourOwnPoetBundle:Form:form_div_layout.html.twig' %}
or you need to change the name of your twig file into fields.html.twig
Both have to match.
