您应该使用 symfony 的表单构建器在您的应用程序中构建表单update_selectedAction()
like
public function update_selectedAction(Request $request, $id, $id_actpost)
{
$em = $this->getDoctrine()->getManager();
$entity = $em->getRepository('ActPostBundle:Edition')->find($id);
if (!$entity) {
throw $this->createNotFoundException('Unable to find Edicion entity.');
}
$defaultData = array('message' => 'Type here');
$form = $this->createFormBuilder($defaultData)
->add('students', 'entity',array('class' => 'PersonBundle:Students',
'property' => 'students','expanded'=>false,'multiple'=>false))
->add('students2', 'entity',array('class' => 'PersonBundle:ForeignStudents',
'property' => 'foreignstudents','expanded'=>false,'multiple'=>false))
->add('submit','submit')
->getForm();
if ($request->getMethod() == "POST") {
$form->submit($request);
if ($form->isValid()) {
$postData = current($request->request->all());
var_dump($postData); /* All post data is here */
/* echo $postData['students']; */
/* echo $postData['students2']; */
/*
* do you update stuff here
* */
}
}
return $this->render('ActPostBundle:Edition:select.html.twig', array('form'=>$form->createView()));
}
在你的树枝中,即ActPostBundle:Edition:select.html.twig
呈现您的表单
{{ form(form) }}
根据评论编辑
在你的树枝文件中渲染你的表单,就像
{{ form_errors(form) }}
{{ form_row(form.students) }}
{{ form_row(form.students2) }}
{{ form_row (form._token) }}
<input type="submit"> /* your submit button */
编辑评论2
如果您想将文本放入选择框的值属性中,您可以使用选择字段类型
$students = $em->getRepository('PersonBundle:Students')->findAll();
$students2 = $em->getRepository('PersonBundle:ForeignStudents')->findAll();
$studentsArray=array();
$students2Array=array();
foreach($students as $s){
$studentsArray[$s->getStudents()]=$s->getStudents();
}
foreach($students2 as $s){
$students2Array[$s->getForeignstudents()]=$s->getForeignstudents();
/* here array key part will be the value of selectbox like $students2Array['your val to get in post data'] */
}
$form = $this->createFormBuilder($defaultData)
->add('students', 'choice',array('choices' => $studentsArray,'expanded'=>false,'multiple'=>false))
->add('students2', 'choice',array('choices' => $students2Array,'expanded'=>false,'multiple'=>false))
->add('submit','submit')
->getForm();
