我們使用propel和Symfony2形式創建了一個集合。我們可以毫無問題地保存表單，並且可以使用該集合添加第二個選項。如果我們再保存，然後嘗試添加第三個集合中，我們得到以下錯誤：Symfony2 + Propel Collection未定義偏移量：2
Notice: Undefined offset: 2

$cton0 = $this->getNewCriterion(LabelsLabelsLinesMapsPeer::ID, $key[0], Criteria::EQUAL);
$cton1 = $this->getNewCriterion(LabelsLabelsLinesMapsPeer::LABEL_ID, $key[1], Criteria::EQUAL);
$cton0->addAnd($cton1);
$cton2 = $this->getNewCriterion(LabelsLabelsLinesMapsPeer::LABEL_LINES_ID, $key[2], Criteria::EQUAL);
$cton0->addAnd($cton2);
$this->addOr($cton0);
}
我已經發布了以下相關的代碼，但是因爲有安靜的大幅代碼量。我們想知道是否有人遇到同樣的問題。
我發送了一個錯誤報告，其中有一個代碼創建了相同的錯誤，但我沒有收到任何回覆。錯誤報告是here。
這是相關的架構的一個片段：

下面是視圖（沒有任何造型）：
{{ 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>
處理此問題的表單：
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' => 'AJSharp\EPCBundle\Model\Labels',
));
}
public function getName()
{
return "label_form";
}
最後，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()));
}
和你的'BaseLabelsLabelsLinesMapsQuery.php'代碼是？ – Alex
@Alex，因爲腳本中有幾行我已將其複製到pastebin中。 http://pastebin.com/WXgfN7yf。請注意，此代碼完全由Propel生成。 –
