我已经在下面发布了相关代码,但是由于存在大量代码.我们想知道是否有人遇到过同样的问题.

我已经使用不同的代码发送了一个错误报告,这会产生相同的错误但是我没有得到回复.错误报告是here.

这是相关架构的片段：

下面是视图(没有任何样式)：

{{ form_start(form) }}
{{ form_row(form._token) }}
<ul class="labelsliness list-group" data-prototype="{{ form_widget(form.labelsliness.vars.prototype)|e }}">
                    {% for lines in form.labelsliness %}
                        <li>{{ form(lines) }}</li>
                    {% endfor %}
                </ul>

                {{ form_row(form.save) }}

{{ form_end(form) }}

<script>
                    var $collectionHolder;

                    var $addLinesLink = $('<button class="add_line_link btn btn-primary">Add a line</button>');
                    var $newLinkLi = $('<li></li>').append($addLinesLink);

                    $(document).ready(function(){
                       $collectionHolder = $('ul.labelsliness');

                       $collectionHolder.append($newLinkLi);

                       $collectionHolder.data('index',$collectionHolder.find(':input').length);

                       $addLinesLink.on('click',function(e) {
                          e.preventDefault();

                          addLineForm($collectionHolder,$newLinkLi);
                       });
                    });

                    function addLineForm($collectionHolder,$newLinkLi) {
                        var prototype = $collectionHolder.data('prototype');

                        var index = $collectionHolder.data('index');

                        var newForm = prototype.replace('/__name__/g',index);

                        $collectionHolder.data('index',index + 1);

                        var $newFormLi = $('<li></li>').append(newForm);

                        $newFormLi.append('<button class="remove-line btn btn-danger">Remove</button>');

                        $newLinkLi.before($newFormLi);

                        $('.remove-line').click(function(e){
                           e.preventDefault();

                           $(this).parent().remove();

                           return false;
                        });
                    }
                </script>

表格处理：

public function buildForm(FormBuilderInterface $builder,array $options)
    {
       $builder
               ->add("labelsliness","collection",array(
                   "type" => new LabelsLinesType(),"allow_add" => true,"allow_delete" => true,"by_reference" => false
               ))
               ->add("save","submit");
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'AJSharpEPCBundleModelLabels',));
    }

    public function getName()
    {
        return "label_form";
    }

最后,下面是控制器.

public function editAction(Request $request,$id = null)
    {

        $labels = LabelsQuery::create()->findPk($id);

        $form = $this->createForm(new EditLabelType(),$labels);

        $form->handleRequest($request);

        if ($form->isValid()) {

            $labels->save();
            return $this->redirect($this->generateUrl("_admin_labels"));
        }

        return $this->render("AppLabelBundle:Admin:edit.html.twig",array("form" => $form->createView()));
    }
