I am generating the form in embedded controller action. And now i have faced the following problem. The Form Theming is not working in that case.
So what i have:
The tempalte "page.html.twig"
{% block content %}
{% render 'MyBundle:Widget:index' %}
{% endblock %}
The indexAction() creates the form and rendering another template "form.html.twig" which is normally renders a form using form_row, form_rest and so on.
So, now i am trying to customize form theming, and here is my problem.
When i put the code
{% form_theme form _self %}
in the page.html.twig, i got an error the the form variable does not exists. And its correct, the form var is created later in the embedded controller.
But when i put the theming code in embedded template "form.html.twig", i got another error "Variable "compound" does not exist"
{% 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 %} {% if attr.tooltip is defined %}title="{{ attr.tooltip }}"{% endif %}>{{ label|trans({}, translation_domain) }}{% if required %}<span>*</span>{% endif %}</label>
{% endspaceless %}
{% endblock form_label %}
This part of code was copied from this file https://github.com/symfony/symfony/blob/2.1/src/Symfony/Bridge/Twig/Resources/views/Form/form_div_layout.html.twig
So tried someone to do something like this?
Answering my question myself.
It was a small sentence in Symfony2 docs http://symfony.com/doc/current/book/forms.html
This {% form_theme form _self %} functionality will only work if your template extends another. If your template does not, you must point form_theme to a separate template.
So there are two solutions to solve this problem:
move form theme code to the separate file and include it in a embedded template using
{% form_theme form with 'fields.html.twig' %}
leave the form theme code in the same template, where the form will be generated, but extend the template from some "form.html.twig" empty template.
I have only done the second way, and its works, but I am sure the first one will work as well.

Shopware6: I want to redirect the page to the "Home page" after registering the customer.
any one can help me?
You could extend the template register.html.twig and set the redirectTo variable.
{% sw_extends '#Storefront/storefront/component/account/register.html.twig' %}
{% block component_account_register_form %}
{% if redirectTo == "frontend.account.home.page" %}
{% set redirectTo = "frontend.home.page" %}
{% endif %}
{{ parent() }}

I've implemented IvoryCKEditorBundle in my SYMFONY 3.2 project.
I followed the guidelines from here and had an overview of the doc on the official Symfony site.
Now I see the following files exits in the IvoryCKEditorBundle directory:
[my
project]\vendor\egoloen\ckeditor-bundle\Resources\views\Form\ckeditor_widget.html.twig
[my
project]\vendor\egoloen\ckeditor-bundle\Twig\CKEditorExtension.php
And [my
project]\vendor\egoloen\ckeditor-bundle\Resources\views\Form\ckeditor_widget.html.twig defines {% block ckeditor_widget %}.
In my projet I have redefined my own template to render a form, using all the tricks given in the official doc. And under [my project]\src\MyBundle\Resources\views I have a file input_inline_template.html.twig which looks like that:
{% extends 'form_div_layout.html.twig' %}
{% use 'CKEditorBundle:Form:ckeditor_widget.html.twig' %}
{% block form_row %}
<div class='col-12' id={{ id ~ '_div_row_id'}}>
{% block form_label %}
<div class='col-4' id={{ id ~ '_div_label_id' }}>
{{ parent() }}
</div>
{% endblock %}
{% if form.vars.block_prefixes.2 == "textarea" %}
{% if (form.vars.block_prefixes.3 is defined) and (form.vars.block_prefixes.3 == "ckeditor") %}
{% block ckeditor_widget %}
<div class='col-8'>
{{ parent() }}
</div>
{% endblock %}
{% else %}
{% block textarea_widget %}
<div class='col-8'>
{{ parent() }}
</div>
{% endblock %}
{% endif %}
{% endif %}
</div>
{% endblock %}
This does not work. It tells me that it cannot find the ckeditor_widget if I don't have the line {% use 'CKEditorBundle:Form:ckeditor_widget.html.twig' %} it throws the error:
Block "ckeditor_widget" on template "form_div_layout.html.twig" does not exist in "form_div_layout.html.twig".
And when the line {% use 'CKEditorBundle:Form:ckeditor_widget.html.twig' %} is implemented, it throws an error that is:
Unable to find template "CKEditorBundle:Form:ckeditor_widget.html.twig"
It tells me it looks for CKEditorBundle:Form:ckeditor_widget.html.twig in:
[my_symf_project]\app/Resources/views, [my_symf_project]\vendor\symfony\symfony\src\Symfony\Bridge\Twig/Resources/views/Form, [my_symf_project]\vendor\knplabs\knp-menu\src\Knp\Menu/Resources/views.
I don't know how to configure in [my project]\app\config\config.yml that it should look in [my project]\vendor\egoloen\ckeditor-bundle\Resources\views\Form\ to find ckeditor_widget.html.twig.
I found a hint here.
In [my project]\src\MyBundle\Resources\views\input_inline_template.html.twig, I've replaced: {% use 'CKEditorBundle:Form:ckeditor_widget.html.twig' %} with: {% use 'IvoryCKEditorBundle:Form:ckeditor_widget.html.twig' %}.
It fixed it.
I'm using Symfony 2.4. What I am trying to do is to set form attributes on the form level which are accessible to each individual widget.
I have a custom form theme which can render the form slightly differently if it is a horizontal or vertical layout. I'd like to be able to specify { 'horizontal': true } as an attribute on the form, then be able to read it while I'm reading each widget.
Is it possible? I want to avoid needing to do this on every widget.
{{ form_row(form.person.province, {horizontal:true}) }}
{{ form_row(form.person.postalCode, {horizontal:true}) }}
{{ form_row(form.person.phone, {horizontal:true}) }}
couldn't you achieve that in your own form theme?
{% block form_row %}
{% spaceless %}
{% if horizontal|default(true) %} {# or something along these lines #}
...
{% else %}
...
{% endif %}
{% endspaceless %}
{% endblock form_row %}
I'm having a problem rendering a custom individual field.
Adding the external template globally (config.yml) works but adding the same block in the same template doesn't.
form_elements.html.twig
{% block _user_email_widget %}
<h1>test</h1>
{% endblock %}
template.html.twig (won't work)
{% form_theme form 'ProjectUserBundle:Form:form_elements.html.twig' %}
{% block content %}
{{form_widget(form.user)}}
{% endblock %}
config.yml (works)
twig:
form:
resources:
- 'ProjectUserBundle:Form:form_elements.html.twig'
Fixed
The problem was on the template:
{% block content %}
{% form_theme form 'ProjectUserBundle:Form:form_elements.html.twig' %}
{{form_widget(form.user)}}
{% endblock %}
This is the right way to do that
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.
