Short Story (Edit) It is possible to store an array instead of a mapped association. In Symfony2, this is fairly easy using the collection Field Type . For example, using this technique, you could store an array of text fields that populate an array events field. However, to update an array, there is a trick, and this trick is beautifully explained by @Vadim Ashikhman in the accepted answer. Long Story Sometimes it is useful and more efficient to store an array instead of a mapped association. However, once created, it remains complicated to update this Array if the size of that array does not

Here is my FormType : public function buildForm(FormBuilder $builder, array $options) { $builder ->add('user', 'entity', array( 'class' => 'UserBundle:User', 'expanded' => true, 'property' => 'name', )); } Is there a way to access user's fields in the view (Twig) ? I'd like to do something like this : {% for u in form.user %} {{ form_widget(u) }} {{ form_label(u) }} {% if u.moneyLeft > 0 %} <span>{{ u.name }} : {{ u.moneyLeft }} €</span> {% endif %} {% endfor %} ... where moneyLeft and name are fields from User entity. In Symfony 2.5 - you can accomplish this by accessing the data from each

I have some complex validation going on with my symfony form, and I need to be able to assign an error to a specific field from my controller. Right now, I have global errors working like this: $error = new formerror("There is an error with the form"); $form->addError($error); But that creates a global error, not one bound to a specific field. Is there a way to throw an error on a specific field from my controller? MrGlass Thanks to some help over IRC (thanks @fkrauthan!) I came up with an answer. Every field in SF2 is actually an instance of form. What you need to do is access the form object

In Twig template I check if a field has an error like this: {% if form.points.get('errors') is not empty %} Is there any method like: {% if form.points.hasErrors() %} to do it simpler? It's not a big difference, but if I can't do it easier why not. That method does not exist. I typically do {% if form.points.vars.errors|length %} . better way I found, is to use this kind of code {% if not form.vars.valid %} <div class="alert alert-error"> {{ form_errors(form) }} </div> {% endif %} You can also check for errors when overriding field rendering: {% block field_row %} {% spaceless %} <div class=

I have an entity field that is passed to twig view, It is rendered and works fine. Is it possible to get the <option> values of that field and render them somewhere else ( I need another select with the same values of that entity field >. say this is my entity field {{ form_widget(entity_field) }} I want something like this <select id="just_another_select"> {% for value in entity_field.values %} <- how to get entity_field.values <option > value </option> {% endfor %} Yes you can get all your options by accesing your field vars see this {{ dump(form.YourFieldName.vars['choices']) }} 来源： https:/
