Is there any Symfony2 option to show some separated text fields from one single text field in a form?
Try to use form customization feature. Please check this article for more information -http://symfony.com/doc/current/cookbook/form/form_customization.html
Example:
form_theme.twig.html
{% block file_widget %}
{% spaceless %}
<td>{% set type = type|default('file') %}
<input type="{{ type }}" {{ block('widget_attributes') }} />
</td>
{% endspaceless %}
{% endblock file_widget %}
template.twig.html
{% form_theme form 'MyBundle:Form:form_theme.html.twig' %}
{{ form_row(form.contract) }}

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 was sure I understand this process, but when I dug deeper I saw I am wrong ;(
Let's take simple form, please notice that this form contains 3 fields
$form = $this->createFormBuilder($defaultData, ['csrf_protection' => false])
->add('email', 'email')
->add('name', 'text')
->add('message', 'textarea')
->getForm()
->createView();
which is rendered as
{{ form(form, {'attr': {'novalidate': 'novalidate'}}) }}
into
Built in "form" block from vendor\symfony\symfony\src\Symfony\Bridge\Twig\Resources\views\Form\form_div_layout.html.twig looks like:
{% block form %}
{% spaceless %}
{{ form_start(form) }}
{{ form_widget(form) }}
{{ form_end(form) }}
{% endspaceless %}
{% endblock form %}
and form_widget(form)
{% block form_widget %}
{% spaceless %}
{% if compound %}
{{ block('form_widget_compound') }}
{% else %}
{{ block('form_widget_simple') }}
{% endif %}
{% endspaceless %}
{% endblock form_widget %}
{% block form_widget_simple %}
{% spaceless %}
{% set type = type|default('text') %}
<input type="{{ type }}" {{ block('widget_attributes') }} {% if value is not empty %}value="{{ value }}" {% endif %}/>
{% endspaceless %}
{% endblock form_widget_simple %}
Let's modify form and form_widget a bit:
{% block form %}
{% spaceless %}
{{ form_start(form) }}
-form_widget before-
{{ form_widget(form) }}
-form_widget after-
{{ form_end(form) }}
{% endspaceless %}
{% endblock form %}
{% block form_widget %}
{% spaceless %}
- form_widget call -
{% if compound %}
- form_widget compound-
{{ block('form_widget_compound') }}
{% else %}
- form_widget simple-
{{ block('form_widget_simple') }}
{% endif %}
{% endspaceless %}
{% endblock form_widget %}
then as an output I got (listing 5):
<form name="form" method="post" action="" novalidate="novalidate">
-form_widget before-
- form_widget call -
- form_widget compound-
<div id="form" novalidate="novalidate">
<div>
<label for="form_email" class="required">Email</label>
<input type="email" id="form_email" name="form[email]" required="required" />
</div>
<div>
<label for="form_name" class="required">Name</label>
- form_widget call -
- form_widget simple-
<input type="text" id="form_name" name="form[name]" required="required" />
</div>
<div>
<label for="form_message" class="required">Message</label>
<textarea id="form_message" name="form[message]" required="required">Type your message here</textarea>
</div>
</div>
-form_widget after-
</form>
we can easly notcie the flow
form -> form_widget (input parameter is the whole form) -> form_widget_compound -> form_rows (iterates form elements into next function) -> form_row -> form_widget (this call form element is passed as parameter)
so here is the time for question, if form_widget is called 4 times (or more), once for form, 3 times for fields then why in listing 5 'form_widget call' text appears only 2 times?
or other words how email and message were rendered?
The form theming in SF2 uses inheritance. That means that if blocks named email_widget and textarea_widget are defined, neither your e-mail nor your textarea fields will use form_widget. They will rather respectively use their own widget blocks: email_widget and textarea_widget.
Well, in form_div_layout.twig, these two widget blocks are defined. Thus form_widget is not called for 2 of your fields. Thus your message is displayed 2 times instead of 4.
If you want to customize the rendering of these fields, you will have to create your own block definitions email_widget and textarea_widget in your custom form theme file.
Edit:
The default form theme files are defined under Symfony\Bridge\Twig\Resources\views\Form. The default file used is form_div_layout.html.twig.
Although the inheritance logic itself is indeed in the PHP code of the TWIG bridge, it does not define which block inherit from which other block.
Inheritance is actually defined in your FormType classes. Each form type class sports a getParent() method that return the name of the form from which it inherits. The name of a form type is the result of the method getName() of its associated form type class. For instance, with a built-in example, Symfony\Component\Form\Extension\Core\Type\TextareaType:
Textarea >> Text >> Field >> Form
All you have to do is to look for the methods getParent() and getName(). Thus, by default, when rendering the textarea row, Twig will search the block textarea_row, text_row, field_row and finally form_row (the base default row). The first of these blocks that is defined in your form theme is rendered.
The definition of the blocks themselves happen in the form theme files.
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
Here's the main form layout twig file:
https://github.com/symfony/symfony/blob/master/src/Symfony/Bridge/Twig/Resources/views/Form/form_div_layout.html.twig
An example:
{% block form_widget_simple %}
{% spaceless %}
{% set type = type|default('text') %}
<input type="{{ type }}" {{ block('widget_attributes') }} {% if value is not empty %}value="{{ value }}" {% endif %}/>
{% endspaceless %}
{% endblock form_widget_simple %}
I wonder where varaibles like "type" or "value" come from?
The goal I'm trying to achieve is to set form row's label as a placeholder in the widget. How can I accomplish this?
Details how to override Template for Form field you will find here.
If you trying to change labels to placeholders all you need is to change way of rendering your forms. Remove form_widget(form) and switch to render every separate form field:
{# ... #}
<div class="form-group">
{{ form_errors(form.email) }}
{{ form_widget(form.email, {'attr': {'class': 'form-control', 'placeholder': 'E-mail address'|trans }}) }}
</div>
{# ... #}
This example generate input for email field and html/css classes for bootstrap.
And shows you how {{ type }} and {{ value }} are passed - by attr array.
Good Luck!
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.
