I'm having a trouble with using Form builder in Symfony2. To be exact, I need input field that is html array, but I can't create it with createFormBuilder->add. Here is what I tried: $attributesForm = $this->createFormBuilder() ->add('attribute[0]', 'text') ... And so on, but I get the following exception: The name "attribute[0]" contains illegal characters. Names should start with a letter, >digit or underscore and only contain letters, digits, numbers, underscores ("_"), hyphens >("-") and colons (":"). Is there any nice solution or I have to create fields manually? Thanks in advance! EDIT:

Any way to access a nested form_bulder.object? ## controller @project = Project.new @project.tasks.build form_for(@project) do |f| f.object.nil? ## returns false fields_for :tasks do |builder| builder.object.nil? ## returns true end end You must have accepts_nested_attributes_for in the Project model in order for the object to be passed. class Project < ActiveRecord::Base has_many :tasks accepts_nested_attributes_for :tasks ## this is required end fields_for requires that the method tasks_attributes= exists. accepts_nested_attributes_for :tasks creates this method for you, but you can also

I want to build a questionnaire form. When I use the following code, I can only see the last question of my table that contains 18 questions (and the answer field). I can't use a collection because my questionnaire is going to be more complicated, some questions with multiple answers, some others in true/false, etc. I simplified the code to fix this problem first. //Get question array collection $questions = $questionnaire->getQuestions(); $formBuilderQuestionnaire = $this->createFormBuilder(); //Make a loop for each question foreach($questions as $question) { //Create an answer form $answer =
