Is there a way to make something like Pre-Label in a Symfony Form? I want to format it differently than the normal label. I already tried it with HTML-injection in the normal label-option, like this:
$form->add('answer', TextAreaType::class, [
'label' => '<span>'.$data->category.'</span>'.$data->description
]);
But this doesn't work. Does someone else has an idea?
I found something like a workaround:
{% for question in question %}
<h1>{{ question.vars["value"].question.category.name }}</h1>
{{ question.vars["value"].question.description }}
{{ form_errors(question) }}
{{ form_widget(question, { 'attr': { 'class': 'form-control' }}) }}
{% endfor %}

I have researched quite a bit and also read the documentation but this thing remains unanswered.
I want to render choice-options separately in twig and a {%for%} loop doesn't seem to work.
Here's the situation:
I have 3 radio buttons which are supplemented with 3 different blocks of html each (therefore I cannot do a loop over the segments as they are different).
Form-Extract (form 'payment'):
array(
'choices' => array(
'paypal' => 'payment.method.paypal',
'bank' => 'payment.method.bank',
'check' => /** #Ignore */
),
'label' => 'payment.method',
'expanded' => 'true',
How could I access the different choice options in twig? I have tried
{{ form_widget(form.payment.method[bank]) }}
and also
{{ form_widget(form.payment.method.bank) }}
Thanks so much for your help.

You might want do it this way:
{% for method in form.payment %}
{% if method.vars.value == "paypal" %}
#Render it in a paypal awesome way
{{ form_widget(method) }}
{{ form_label(method) }}
{% else if method.vars.value == "bank" %}
#Render it in a bank awesome way
{{ form_widget(method) }}
{{ form_label(method) }}
{% endif %}
{% endfor %}
Hope it helps
I want to print all errors in one go for all the fields however {{ form_errors(form) }} doesn't print anything so because of that I have to use if not form.vars.valid statement to print errors however all the individual error messages are being wrapped within <ul><li>Message</li></ul> which is annoying. I know that 'error_bubbling' => true solves the issue but creates another issue which is making field borders red.
How can I solve this issue? I simply want to print error without tags.
Note: I can use {{ form_errors(form.name)|striptags }} but it adds overheads cos my form is massive.
FORM TYPE

Customize the field template
You can apply a form template to your form, check this documentation at Form Theming chapter.
If you prefer theming the field directly in your template, check the gray box in this documentation at the Global Form Theming chapter.
Check this documentation for more form customization.
Pass the errors to the template
When you submit the form, your code will call this method $form->handleRequest($request); which will check if the user input properly the data.
Based on the documentation of the Form class you can get a list of errors by calling $form->getErrors(). The variable $form is an instance of the Form class and not the FormView class. You may want to enable error bubbling.
Now that you know how to get the errors you can pass them as a variable to your template.
I am using FOSUserBundle for managing my users. In order to register user, I reused the form of the bundle which meets my needs. Nevertheless, I needed to set some attributes of my fields. This is was done easyly by twig like this:
{{ form_widget(form.username, { 'attr': {'class': "span12",
'placeholder': "Username"} }) }}
Now, my goal is to make automatic translation on my placeholder, so I proposed this code:
{{ form_widget(form.username, { 'attr': {'class': "span12",
'placeholder': "{{'security.login.usernameplaceholder'|trans}}"} }) }}
This previous code produced an input with placeholder value equal to {{'security.login.usernameplaceholder'|trans}}
To get rid of this problem, I tried to set variable for that but symfony generated an error!!!
{% set usernameplaceholder = {{'security.login.usernameplaceholder'|trans}} %}
{{ form_widget(form.username, { 'attr': {'class': "span12",
'placeholder': usernameplaceholder} }) }}
Is there any proposition to solve this problem?
Thanks,
In Twig you shouldn't put {{ within {{ (same for {%); think of it as the php tag.
The following should work
{% set usernameplaceholder = 'security.login.usernameplaceholder'|trans %}
{{ form_widget(form.username, { 'attr': {'class': "span12",
'placeholder': usernameplaceholder} }) }}
OR
{{ form_widget(form.username, { 'attr': {'class': "span12",
'placeholder': 'security.login.usernameplaceholder'|trans} }) }}
For Symfony 3.x, 4.x
Another way to add placeholders (or any attributes for that matter) is by passing an options-array to the form $builder containing another Array attr with attributes as key-value pairs.
// The parameters are column name, form-type and options-array respectively.
$builder->add('field', null, array(
'attr' => array(
'placeholder' => 'support.contact.titleplaceholder'
)
));
You can translate this way as well (Using symfony4) in twig:
In a form placeholder wich would be written like this:
{'attr':{'placeholder': "Text to translate"}}
As for a placeholder in html wich would be written like this, you can translate this way:
<input placeholder="{{"Text to translate"|trans }}">
If you want to set the placeholder in the form-type (and not in the template) you must the placeholder inside the attr option. For example:
->add('search', TextType::class, ['attr' => ['placeholder' => 'form.custom.placeholder']])
To have the placeholder then translated in the background, you must adjust the form-theme.
In our case we wanted to trigger automatic translation only if the translation_domain is set explicitly in the form-type. This is how we achieved automatic translation:
{% block form_widget_simple -%}
....
{% if attr.placeholder|default and translation_domain|default %}
{%- set attr = attr|merge({placeholder: (attr.placeholder|trans({}, translation_domain))|trim}) -%}
{% endif %}
....
{{- parent() -}}
{%- endblock form_widget_simple %}
If you want to always trigger automatic translation. This should work:
{% block form_widget_simple -%}
....
{%- set attr = attr|merge({placeholder: (attr.placeholder|default|trans({}, translation_domain))|trim}) -%}
....
{{- parent() -}}
{%- endblock form_widget_simple %}
You can also add it to your form definition like this:
$builder
->add('information', 'textarea', array(
'label' => false,
'required' => true,
'constraints' => [
new NotBlank()
],
'attr' => [
'placeholder' => 'support.contact.titleplaceholder'
]
));
In my registration form i have a checkbox "I accept the terms", and want to link the word "terms" to my terms page.
Is there a way to add a link to a form label, using a route? (preferably without injecting the container in the form)
As the solution above somehow didn't work for me I solved it using the solution suggested here: https://gist.github.com/marijn/4137467
OK, so here i how I did it:
{% set terms_link %}<a title="{% trans %}Read the General Terms and Conditions{% endtrans %}" href="{{ path('get_general_terms_and_conditions') }}">{% trans %}General Terms and Conditions{% endtrans %}</a>{% endset %}
{% set general_terms_and_conditions %}{{ 'I have read and accept the %general_terms_and_conditions%.'|trans({ '%general_terms_and_conditions%': terms_link })|raw }}{% endset %}
<div>
{{ form_errors(form.acceptGeneralTermsAndConditions) }}
{{ form_widget(form.acceptGeneralTermsAndConditions) }}
<label for="{{ form.acceptGeneralTermsAndConditions.vars.id }}">{{ general_terms_and_conditions|raw }}</label>
</div>
The best way is to overwrite the twig block used to render that specific label.
First, check the form fragment naming section of the docs. Then create a new block in your form template with the the appropriate name. Don't forget to tell twig to use it:
{% form_theme form _self %}
For the next step check the default form_label block.
You'll probably only need a portion of it, something like this (I'm leaving the default block name here):
{% block form_label %}
{% spaceless %}
<label{% for attrname, attrvalue in label_attr %} {{ attrname }}="{{ attrvalue }}"{% endfor %}>
{{ label|trans({}, translation_domain) }}
</label>
{% endspaceless %}
{% endblock %}
As an option, you can do so:
->add('approve', CheckboxType::class, [
'label' => 'Text part without link',
'help' => 'And download it',
'help_html' => true,
])
In Symfony 5.1 there are new form improvements.
HTML contents are allowed in form labels!
HTML contents are escaped by default in form labels for security reasons. The new label_html boolean option allows a form field to include HTML contents in their labels, which is useful to display icons inside buttons, links and some formatting in checkbox/radiobutton labels, etc.
// src/Form/Type/TaskType.php
namespace App\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Component\Form\FormBuilderInterface;
class TaskType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
// ...
->add('save', SubmitType::class, [
'label' => ' Save',
'label_html' => true,
])
;
}
}
In your case you can set form label directly from template and pass the route there.
{{ form_widget(form.acceptTermsAndConditions, {
label: '' ~ "I accept ..."|trans ~ '',
label_html: true
})
}}
My solution was another:
form:
$builder
->add(
'agree_to_rules',
'checkbox',
[
'required' => true,
'label' => 'i_agree_to'
]
);
And html:
<span style="display:inline-block">
{{ form_widget(form.agree_to_rules) }}
</span>
<span style="display:inline-block">
rules
</span>
And looks the same :)
A very simple way to do it would be
{{ form_widget(form.terms, { 'label': 'I accept the terms and conditions' }) }}
You can also do this if you want to use translation
In your translation file for example messages.en.yml add
terms:
url: 'I accept the terms and conditions'
And in your view add
{{ form_widget(form.terms, { 'label': 'terms.url'|trans({'%url%': path('route_to_terms')}) }) }}
Maybe I'm overlooking something, and hopefully this is done very easy.
I have a form and what I want in the end is the following result:
Fields which:
are mandatory/required
have an error currently
have help
should get an extra a-Tag after the label and an extra div, filled with the help and/or the error, if applicable.
What I got to work is, that required fields get the a-Tag by using this:
{% use 'form_div_layout.html.twig' with field_label as base_field_label %}
{% block field_label %}
{{ block('base_field_label') }}
{% if required %}
<span> </span>
{% endif %}
{% endblock %}
So, what I tried already were different versions of this:
{% use 'form_div_layout.html.twig' with field_label as base_field_label %}
{% block field_label %}
{{ block('base_field_label') }}
{% if required or help is defined %}
<span> </span>
{% endif %}
{% endblock %}
{% block field_row %}
{% spaceless %}
<div class="row">
{% if required or help is defined %}
<div>
{{ form_errors(form) }}
{{ help }}
</div>
{% endif %}
{{ form_label(form) }}
{{ form_widget(form, { 'attr': {'class': 'grid_4'} }) }}
</div>
{% endspaceless %}
{% endblock field_row %}
And I can't get this to work.
So my questions are:
Where do I get the help text from, which can also contain HTML? I tried this within the form builder without success - but at least with an exception:
$builder ->add('subject', 'text', array(
'label' => 'Subject',
'help' => 'Can be formatted content with <strong>HTML-Elements</strong>',
));
How can I tell that the current field has an error (to add a class to the row) and if so also display it? {{ form_errors(form) }} did not output anything, no matter where I place it within `field_row˚.
There is no help text, you have to create Form Extension for field and add it to default options.
Example in SF 2.1 Beta 1:
namespace Webility\Bundle\WebilityBundle\Form\Extension;
use Symfony\Component\Form\FormInterface;
use Symfony\Component\Form\FormViewInterface;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\AbstractTypeExtension;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class HelpFormTypeExtension extends AbstractTypeExtension
{
public function buildView(FormViewInterface $view, FormInterface $form, array $options){
$view->setVar('help', $options['help']);
}
public function getExtendedType(){
return 'field';
}
public function setDefaultOptions(OptionsResolverInterface $resolver) {
$resolver->setDefaults(array(
'help' => null
));
}
}
And register it as a service:
<service id="webility.form.extension.help" class="Webility\Bundle\WebilityBundle\Form\Extension\HelpFormTypeExtension">
<tag name="form.type_extension" alias="field" />
</service>
For the errors question:
Do you have any errors to print? Check that in controller if validation fails:
echo '<pre>'; print_r( $form->getErrorsAsString() ); echo '</pre>'; exit;
To solve it as stated in my question Maciej Pyszyński's anwser was very helpful.
I solved it in this case in another way, which I also want to post here. According to the manual "Adding "help" messages" I build this:
Note This solution won't work together with the formbuilder and needs some tweaking in twig.
To get the help ''-tags (actually they are divs now) …
{% block field_label %}
{{ block('base_field_label') }}
{% if attr.class is defined and '_hint' == attr.class %}
<div>
<a><span class="help">Help Icon</span></a>
<div class="tooltip">
{% if help is defined %}
{{ help|raw }}
{% else %}
Somebody forgot to insert the help message
{% endif %}
</div>
</div>
{% endif %}
{% endblock %}
To get the right class on an error
{% block field_row %}
{% spaceless %}
<div class="row{% if form_errors(form) %} error{% endif %}">
{{ form_label(form) }}
{{ form_widget(form, { 'attr': {'class': 'grid_4'} }) }}
</div>
{% endspaceless %}
{% endblock field_row %}
And the call from the template
<div class="row{% if form_errors(form.url) %} _error{% endif %}">
{{ form_label(form.field, null, { 'attr': {'class': '_hint'}, 'help': 'Help text or variable containing it' }) }}
{{ form_widget(form.field, { 'attr': {'class': 'grid_4'} }) }}
</div>
