Symfony 2.8
I'm trying to override some blocks of bootstrap themes for forms.
Particularly interested the block "form_label_class" in the theme "bootstrap_3_horizontal_layout.html.twig":
{% block form_label_class -%}
col-sm-2
{%- endblock form_label_class %}
I created the file my_form.html.twig and inherited it from "bootstrap_3_horizontal_layout.html.twig":
{% use "bootstrap_3_horizontal_layout.html.twig" %}
{% block form_start -%}
...
{% endblock form_start -%}
{% block form_label_class -%}
{{ width_test }}
{%- endblock form_label_class %}
Also added the definition of "width_test" in the form class:
....
public function buildView(FormView $view, FormInterface $form, array $options)
{
$view->vars['width_test'] = $options['width_test'];
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefault('width_test', 3);
}
The problem: as a result of getting the error:
Variable "width_test" does not exist in form/my_form.html.twig
Importantly, "width_test" is not defined only in the block "form_label_class", but no problems to display it for example in the block "form_start"

I created a global Action :
public function export(
Admin $user,
StructureRepository $structureRepository,
ExportCsvEntity $exportCsvEntity,
string $entityClass
): HttpFoundationResponse {
$zipcodes = $structureRepository->getZipcodesByStructureFromAdmin($user->getId());
$exportCsvEntity->export(
$zipcodes,
$entityClass
);
return $exportCsvEntity->download($entityClass);
}
public function exportButton(): Action
{
return Action::new('export', 'admin.crud.user.field.activities_tracking.button.export')
->linkToCrudAction('export')
->displayAsLink()
->setCssClass('btn btn-primary')
->createAsGlobalAction()
;
}
Then in my Crud Controller I call it :
if ($this->getUser() instanceof Admin) {
$export = $this->exportAction->exportButton();
$actions->add(Crud::PAGE_INDEX, $export);
}
In the doc its written => Global actions are displayed above the listed entries.
But in my case the button is underneath the table
Have a look here
My template is extending '#!EasyAdmin/crud/index.html.twig'then I override the global_actions block :
{% block global_actions %}
{{ parent() }}
{% endblock global_actions %}
Now my button is above the table but also underneath :

What do I do wrong ?
You are correct when trying to do this by overriding the index template.
An easy way to do this considering how the template is organized is to modify the global_actions block by filtering actions you do not want to show above the list. For example by using a css class to not show a global action above the list.
{% block global_actions %}
<div class="global-actions">
{% for action in global_actions|filter(a => 'under-list' not in a.cssClass) %}
{{ include(action.templatePath, { action: action }, with_context = false) }}
{% endfor %}
</div>
{% endblock global_actions %}
And in your crud controller:
Action::new('customAction', $label, $icon)
->addCssClass('under-list')
->createAsGlobalAction()
->linkToCrudAction('customAction');
And you need to add your new list of actions under your list by overriding the main block.
{% block main %}
{{ parent() }}
{% block under_list_global_actions %}
<div class="under-list-global-actions">
{% for action in global_actions|filter(a => 'under-list' in a.cssClass) %}
{{ include(action.templatePath, { action: action }, with_context = false) }}
{% endfor %}
</div>
{% endblock under_list_global_actions %}
{% endblock main %}
And you should get your custom global action (with the css class under-list) under your list.
In my model (Task) I have a function:
public function isTaskOverdue()
{
if ("now"|date('Y-m-d') > task.deadline|date('Y-m-d')){
return false;
} else{
return true;
}
}
In twig (edit) I want to display form:
{% extends 'base.html.twig' %}
{% block title %}app:Resources:Task:edit{% endblock %}
{% block body %}
{{ form(form) }}
{% endblock %}
I want to display form, if this function return true.
How can I call this function in twig?
Pass the task entity to twig and call method from object task :
{% if task.isTaskOverdue %}
{{ form(form) }}
{% endif %}
I think it should be your controller that receives the function result and display the form or not depending on it.
Also you can write your function like so :
public function isTaskOverdue()
{
return ("now"|date('Y-m-d') > task.deadline|date('Y-m-d'));
}
Pass the task entity to twig and do :
{% extends 'base.html.twig' %}
{% block title %}app:Resources:Task:edit{% endblock %}
{% block body %}
{% if "now"|date("Ymd") <= task.deadline|date("Ymd") %}
{{ form(form) }}
{% endif %}
{% endblock %}
But, caution :
If you just not display the form, there is a security issue, because if an attacker submit the form from an self rebuilded HTML page, your controller will receive the form data and apply it.
So I would do the check in the controller, and only create and pass the form to the twig template if the condition is true.
Then, in twig you can use :
{% if form is defined %}
{{ form(form) }}
{% endif %}
In my app I'm trying to display form help block using tips from official Symfony2 cookbook. Here is my code:
{% extends 'form_div_layout.html.twig' %}
{% block form_widget_simple %}
{{ block('base_form_widget_simple') }}
{{ dump(help) }}
{% if help is defined %}
<span class="help">{{ help }}</span>
{% endif %}
{% endblock %}
And using this theme:
{{ form_row(form.pageTitle, {'help': 'some help'}) }}
With this I'm getting error Variable "help" does not exist. Any ideas what have I missed?
P.S. I use Symfony 2.7.1.
Create a Form type extension extending the form type:
namespace Acme\AppBundle\Form\Extension;
use ...
class FieldTypeHelpExtension extends AbstractTypeExtension
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->setAttribute('help', $options['help']);
}
public function buildView(FormView $view, FormInterface $form, array $options)
{
$view->vars['help'] = $options['help'];
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'help' => null
]);
}
public function getExtendedType()
{
return 'form';
}
}
Define the extension as a service:
acme_app.form.extension.field_type_help:
class: Acme\AppBundle\Form\Extension\FieldTypeHelpExtension
tags:
- { name: form.type_extension, alias: form }
Create a template extending form div layout:
{% extends 'form_div_layout.html.twig' %}
{% block field_help %}
{% if help is defined and help %}
<p class="help-block">{{ help|trans }}</p>
{% endif %}
{% endblock field_help %}
{% block integer_widget %}
{{ parent() }}
{{ block('field_help') }}
{% endblock integer_widget %}
{% block form_widget %}
{{ parent() }}
{{ block('field_help') }}
{% endblock form_widget %}
Configure this template as form theme on config.yml
twig:
form_themes:
- 'Form/fields.html.twig'
Now you can use it when render the a field on a template:
{{ form_widget(form.name, { 'help': 'this is help' }) }}
Or in your Form type:
$form->add('name', 'text', ['help' => 'this is help']);
I have created a custom form type and contraint in Symfony.
The constraint is attached to the form type like this:
->add('customField', 'customField', array(
'required' =>
'mapped' => false,
'constraints' => array(new CustomField()),
))
where CustomField is the constraint class.
The constraint validator's validate() method looks like this:
public function validate($value, Constraint $constraint)
{
//I know this will always fail, but it's just for illustration purposes
$this->context->addViolation($constraint->message);
}
I have changed the form's default template like this:
{% block form_row -%}
<div class="form-group">
{{- form_widget(form) -}}
{{- form_errors(form) -}}
</div>
{%- endblock form_row %}
{% block customField_widget %}
{% spaceless %}
<!-- actually different but you get the idea -->
<input type="text" name="customField" id="customField" />
{% endspaceless %}
{% endblock %}
{% block form_errors -%}
{% if errors|length > 0 -%}
{%- for error in errors -%}
<small class="help-block">
{{ error.message }}
</small>
{%- endfor -%}
{%- endif %}
{%- endblock form_errors %}
And in the template where the form is displayed, I've added some code to display the errors attached to the whole form rather than individual field errors:
{{ form_start(formAdd) }}
{% if formAdd.vars.valid is same as(false) -%}
<div class="alert alert-danger">
<strong>Errors!</strong> Please correct the errors indicated below.
{% if formAdd.vars.errors %}
<ul>
{% for error in formAdd.vars.errors %}
<li>
{{ error.getMessage() }}
</li>
{% endfor %}
</ul>
{% endif %}
</div>
{%- endif %}
...
The problem with all this, the validator of this particular field, is attaching the constraint violation to the form object and not to the customField form type. This causes the error to be finally displayed with the form's general errors instead of being displayed as a field error.
Now, this is not the only custom form type and validator I added but it's the only one that displays this behavior, without me being able to identify the difference between this one and the rest. Can you spot what is wrong here?
I have sorted this out myself. It has nothing to do with the contraint or the validator. The issue was with the custom form type (which I haven't described in my question). The problem was that this form type had "form" as a parent which is a compound type. This means that by default (according to the docs), the error bubbling is also true and that, in turn, means that "any errors for that field will be attached to the main form, not to the specific field".
You have to specify path in your validator:
$this->context
->buildViolation($constraint->message)
->atPath('customField')
->addViolation();
You have to set 'error_bubbling' to false in your custom form type
class CustomFieldType extends AbstractType
{
public function getName()
{
return 'customField';
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefault('error_bubbling', false);
}
}
I want to validate my form using server side validation only. However, if the browser supports HTML5 it validates using the HTML5 attributes added to the form by symfony2 so I need to prevent HTML5 validation.
Just add novalidate to your <form> tag:
<form novalidate>
If you are rendering the form in TWIG, you can use following.
{{ form(form, {'attr': {'novalidate': 'novalidate'}}) }}
I know its old question but with SF2.6 in FormType, you can do:
/**
* #param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'attr'=>array('novalidate'=>'novalidate')
));
}
While googling for a solution to this I found one, that seems the most elegant if you want to disable html5 validation in your whole app, so I thought i'd share it here. Credits go to the author of this blog article.
The idea is to create an extension for the "form" form type like this:
<?php
// src/AppBundle/Form/Extension/NoValidateExtension.php
namespace AppBundle\Form\Extension;
use Symfony\Component\Form\AbstractTypeExtension;
use Symfony\Component\Form\FormInterface;
use Symfony\Component\Form\FormView;
class NoValidateExtension extends AbstractTypeExtension
{
public function buildView(FormView $view, FormInterface $form, array $options)
{
$view->vars['attr'] = array_merge($view->vars['attr'], [
'novalidate' => 'novalidate',
]);
}
public function getExtendedType()
{
return 'form';
}
}
?>
Then you just register it in your services.yml like this:
app.no_validation_form_extension:
class: AppBundle\Form\Extension\NoValidateExtension
tags:
- {name: form.type_extension, alias: form}
and you're done. All your forms automatically have a novalidate attribute now.
Symfony 3.3
As of Symfony 3.3 the configuration is slightly different, but still possible.
Slight update to the getExtendedType method to return the FormType class.
// src/AppBundle/Form/Extension/NoValidateExtension.php
namespace AppBundle\Form\Extension;
use Symfony\Component\Form\AbstractTypeExtension;
use Symfony\Component\Form\FormInterface;
use Symfony\Component\Form\FormView;
use Symfony\Component\Form\Extension\Core\Type\FormType;
class NoValidateExtension extends AbstractTypeExtension
{
public function buildView(FormView $view, FormInterface $form, array $options)
{
$view->vars['attr'] = array_merge($view->vars['attr'], [
'novalidate' => 'novalidate',
]);
}
public function getExtendedType()
{
return FormType::class;
}
}
Plus some a minor addition of the extended_type tag, which is now required in your service declaration:
app.no_validation_form_extension:
class: AppBundle\Form\Extension\NoValidateExtension
tags:
- {name: form.type_extension, alias: form, extended_type: Symfony\Component\Form\Extension\Core\Type\FormType}
Alternatively if for some reason you don't want to do it in twig as in the answer above...
{{ form(form, {'attr': {'novalidate': 'novalidate'}}) }}
or you create your from manually with createFormBuilder then you could simply use createFormBuilder as a second parameter to define form attribute:
//someAction
$form = $this->createFormBuilder(null, ['attr'=>['novalidate'=>'novalidate']])
->add(...)
->add(...)
->add(...)
->getFrom();
return $this->render("-----:----:----.html.twig", [
'form'=>$form->createView()
]);
If you are using Symfony 3 (or 2) and want to turn off validation for a specific field only you can do this.
$form = $this->createFormBuilder($task)
->add('task', TextType::class, array('required' => false))
->add('dueDate', DateType::class)
->add('save', SubmitType::class, array('label' => 'Create Task'))
->add('saveAndAdd', SubmitType::class, array('label' => 'Save and Add'))
->getForm();
In this sample form notice the array('required' => false), you can add this to any element that you want to disable validation for without disabling validation for the others. Very useful if you want to temporarily disable only one element instead of the entire form.
Note this ONLY disables the HTML5 validation! This does not disable server side validation.
Reference: http://symfony.com/doc/current/book/forms.html#field-type-options
If you actually need to remove the validation attributes (if you are using a validation library want to keep all of your validation constraints in one place for example), you can overwrite the widget_attributes block in twig.
If you are already using custom form templates in app/Resources/views/form.html.twig for example (and have enabled it in your config.yml) you can just add a block for
{% block widget_attributes %}
{% spaceless %}
id="{{ id }}" name="{{ full_name }}"{% if read_only %} readonly="readonly"{% endif %}{% if disabled %} disabled="disabled"{% endif %}
{% for attrname, attrvalue in attr %}{% if attrname in ['placeholder', 'title'] %}{{ attrname }}="{{ attrvalue|trans({}, translation_domain) }}" {% else %}{{ attrname }}="{{ attrvalue }}" {% endif %}{% endfor %}
{% endspaceless %}
{% endblock widget_attributes %}
All I have done here is remove the attributes related to validation:
{% if required %} required="required"{% endif %}{% if max_length %} maxlength="{{ max_length }}"{% endif %}{% if pattern %} pattern="{{ pattern }}"{% endif %}
To disable Regex validation for specific field using formType class:
->add('foo',null,array=>('attr'=>('pattern'=>'/[^~,]/'))
Use form theming:
First create form theme template, e.g app/Resources/views/form/fields.html.twig:
{% extends 'form_div_layout.html.twig' %}{# or some other base layout #}
{% block form_start %}
{% if attr.novalidate is not defined %}
{% set attr = attr|merge({'novalidate':'novalidate'}) %}
{% endif %}
{{ parent() }}
{% endblock %}
Then use that form theme in your template:
{% form_theme form with 'form/fields.html.twig' %}
{{ form_start(form) }} <-- now renders with novalidate attribute
...
{{ form_end(form) }}
Or, apply theme globally (app/config/config.yml):
twig:
form_themes:
- ':form/fields.html.twig'
