问题 How can I render an individual field (single radio/checkbox input field) in Twig in Symfony 2.6? Let's say I have a simple form: class TransportType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder->add('transport', 'choice', array( 'choices' => array( 'road' => 'Car/bus', 'train' => 'Train', ), 'expanded' => true, 'multiple' => false )); } In previous Symfony2 versions I could just use: {{ form_widget(form.transport.road) }} {{ form

问题 Using Symfony2 entity field type one should specify property option: $builder->add('customers', 'entity', array( 'multiple' => true, 'class' => 'AcmeHelloBundle:Customer', 'property' => 'first', )); But sometimes this is not sufficient: think about two customers with the same name, so display the email (unique) would be mandatory. Another possibility is to implement __toString() into the model: class Customer { public $first, $last, $email; public function __toString() { return sprintf('%s %s

问题 How Can I add get container in form builder symfony ? I would like use $get->container in form builder... 回答1: Injecting the whole container into a form type is a bad practice. Please consider injecting only required dependencies to your form type. You can simply define your form type as a service and inject required dependencies. src/AppBundle/Form/TaskType.php use Doctrine\ORM\EntityManagerInterface; // ... class TaskType extends AbstractType { private $em; public function __construct

问题 I'm using the select2 plugin with ajax to have a dynamic field on my form, but when i submit the it return me an error "This value is not valid" , which is normal cause i use the ChoiceType with an empty array() in the choices options on creation. According to this part of the symfony doc, the form event is my savior, so trying to use it but it look like something wrong with my code and can't really see what. So My Question Is : HOW to pass the choices possibility to the field, for the form

问题 I wanted to add particular style to my CollectionType in twig and I received a solution here : Symfony/Jquery Collection of objects. Now I have a little problem that I can't solve : I have this custom form_row : // src/MyBundle/Ressources/views/CustomForms {% block form_row %} <div class="row"> <div class="form-group{% if (not compound or force_error|default(false)) and not valid %} has-error{% endif %}"> <div class="col-lg-4 col-md-4 col-sm-6 col-xs-12"> {{- form_label(form, "", {'label_attr

问题 I got an entity called 'Activity', that defines a relation between 2 more entities, 'Service' and 'Location'. Both 'Service' and 'Location', use another entity called 'Allocation', to define what services can be used in a concrete location. When I create a new Activity, after selecting a service I want the location choice field update with the values defined by allocation. I have followed symfony documentation to create this 'location' dependent choice field in the form. Dynamic Form

问题 I made a DataTransformer that is made to basically NOT the available choices with the submitted ones. My issue is that my transformer receives either ['INFO' => 'INFO', 'WARN' => 'WARN'] or [0 => 'INFO', 1 => 'WARN'] . This usually happens when all the checkboxes are unchecked (AKA the model data of the choice is ['INFO', 'WARN']) and that I check any and submit the form. I am using Symfony 2.6.6. Here is the form : $choice = $builder->create('choice', 'choice', array( 'choices' => array(
