问题 In my filter, a field's behaviour is to search in the DB table for a row that has the value of the field equal to the value provided in filtering form. I'd like to change its behavior to search in DB table for a row/rows that have field value matching to that provided in the form( %LIKE% ). I know it can be done by adding a addFieldnameColumnQuery method to the filter class but What I want to know is, is there another way? The field happens to be a foreign key and I want it to work like a

问题 A simple question: I have one form, it returns one number and I need create this number of labels in Controller. I try: $form2 = $this->createFormBuilder(); for($i = 0; $i < $num; $i++) { $name = 'column'.$i; $form2->add($name,'number'); } $form2->getForm(); I think it should very simple, but i can't.. 回答1: Yes, you can do it with an array / hash map instead of a real object. Here is an example : // Create the array $dataObj = array(); $dataObj['data1'] = ''; $dataObj['data2'] = 'default'; //

问题 I have a custom form type that defines some default attr options: public function setDefaultOptions(OptionsResolverInterface $resolver) { $resolver->setDefaults(array( 'invalid_message' => 'The selected image does not exist', 'attr'=>array( 'data-image-picker'=>'true', 'data-label'=>'Pick Image' ), )); } However when i use this custom form type the entire attr array is replaced with what is defined. $builder->add('logo','image_picker',array( 'attr'=>array( 'data-label'=>'Logo' ), )); When the

问题 I'm following the tutorial How to Dynamically Generate Forms Using Form Events. I'm stuck on the creation of AddNameFieldSubscriber : $subscriber = new AddNameFieldSubscriber($builder->getFormFactory()); My question is simple: how FormFactory can access and modify an arbitrary form field previously created by the $builder ? And why we are passing the FormFactory instead of the $builder itself? Assuming we have just two fields ("name" and "price") in the builder : class ProductType extends

问题 I have a form with three buttons. One for adding objects, one for deleting and one for editing objects. I now want to disable html5-validation in the add-button using the new form buttons introduced in Symfony 2.3. Is this possible or do I have to create a new button type? How could I do that? 回答1: All you need to do is to add the html attribute novalidate or novalidate="novalidate" to the element. You can do this same way you would add any other attribute from either the form type of the

问题 I have object A which contains a collection of objects B which in turn contain a collection of objects C which again contains a collection of object D. I need to retrieve object A from DB, create a form from it, change some values in fields of the form (in the future also add and remove elements from the collections) and persist on DB a new object A with all the appropriate references to the new B, new C and new D. The object CVC below is my A. If I do: $storedCVC = $this->getDoctrine() -

Im not sure how to accomplish this. public function buildForm(FormBuilderInterface $builder, array $options) { $builder->add('first_field','choice',array( 'choices'=>array('1'=>'First Choice','2'=>'Second Choice') )); $builder->addEventListener(FormEvents::PRE_SET_DATA, array($this, 'preSetData')); $builder->get('first_field')->addEventListener(FormEvents::POST

问题 Is there a way to make a A2lix translation field required and validated through the front-end in a Symfony form? I have tried adding a property of presentation and translations to my validation.yml file, but to no avail. I find that when I don't enter anything in the translation field the form doesn't submit, but nothing happens. No FE or BE error. My form: /** * {@inheritdoc} */ public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('translations', 'a2lix
