我知道 symfony 1.4 表单系统不是最好的，给很多人带来很多麻烦，但我需要完成这项任务，我需要帮助。
我需要将子表单嵌入到嵌入主表单的子表单中，并通过 Ajax 进行。
基本上我有 aForm、bForm 和 cForm 并且 aForm 嵌入 bForm 和 bForm 可以有一个或多个 cForm。
当我从每个表单的 configure() 函数中正常嵌入它们时，它可以工作。但是当我尝试使用 Ajax 将多个 cForms 嵌入到 bForm 中时，我无法绑定它们。
这是有效的版本。一切都很好嵌入并且验证正常。
class BookingForm extends BaseBookingForm
{
public function configure()
{
$this->embedRelation('Journey as journey');
}
}
[...]
class JourneyForm extends BaseJourneyForm
{
public function configure()
{
$pickup_form = new JourneyItineraryForm();
$this->embedForm('pickup_form', $pickup_form);
}
}
[...]
class JourneyItineraryForm extends BaseJourneyItineraryForm
{
public function configure()
{
}
}
[...]
现在，如果我尝试通过 ajax 嵌入 JourneyItineraryForm，我设法让小部件显示在模板中，但无法绑定它们。它对我说意外的额外表单字段名为“航点”。
查看下面的代码：
class JourneyForm extends BaseJourneyForm
{
public function configure()
{
$waypoint_form = new JourneyItineraryForm();
$this->embedForm('waypoint', $waypoint_form);
}
public function addNewWaypoint($number)
{
/*
* Called from actions.class.php after an ajax request
*/
$new_waypoints = new BaseForm();
for($i=0; $i <= $number; $i+=1)
{
$waypoint = new JourneyItinerary();
$waypoint_form = new JourneyItineraryForm($waypoint);
$new_waypoints->embedForm($i,$waypoint_form);
}
$this->embedForm('waypoint', $new_waypoints);
}
public function bind(array $taintedValues = null, array $taintedFiles = null)
{
$new_occurrences = new BaseForm();
foreach($taintedValues['waypoint'] as $key => $new_occurrence)
{
$occurrence = new JourneyItinerary();
$occurrence_form = new JourneyItineraryForm($occurrence);
$new_occurrences->embedForm($key,$occurrence_form);
}
$this->embedForm('waypoint',$new_occurrences);
parent::bind($taintedValues, $taintedFiles);
}
}
我的模板我设法显示航点小部件，例如
$form['journey']['waypoint'][0]['field_name']->renderRow();
我还尝试从 BookingForm 覆盖 bind 方法，但我不知道我是否正确：
public function bind(array $taintedValues = null, array $taintedFiles = null)
{
$new_occurrences = new sfForm();
foreach($taintedValues['journey']['waypoint'] as $key => $new_occurrence)
{
$occurrence = new JourneyItinerary();
$occurrence_form = new JourneyItineraryForm($occurrence);
$new_occurrences->embedForm($key,$occurrence_form);
}
$this->embedForm('journey',$new_occurrences);
parent::bind($taintedValues, $taintedFiles);
}
我遵循了本教程： http ://tech.cibul.net/embedded-forms-with-symfony-1-4-and-jquery/ 并阅读了官方文档http://symfony.com/legacy/doc/more -with-symfony/1_4/en/06-Advanced-Forms
非常感谢任何帮助:) 谢谢。
