symfony2创建没有实体类的表单 [英] symfony2 create form without entity class
问题描述
使用Symfony2.3.4.
Using Symfony2.3.4.
我正在尝试创建一个不使用类型的表单，它实际上是一个很小的表单，只有两个选择从数据库中加载其选项，到目前为止，它仍然有效，我不能做的就是获取表单数据(在控制器中)提交时.我试图按照说明此处但我做对了.
I'm trying to create a form without using a type, it is actually a very small form, only two selects loading their options from the database, so far it works, what I can not do is to get the form data(in the controller) when it is submitted. I tried to follow the instruction here but I can't get it right.
到目前为止，这是我的代码:
Here is my code so far:
控制器: 将数据传递给表单的函数:
Controller: function to pass the data to the form:
public function selectAction($id, $id_actpost){
$em = $this->getDoctrine()->getManager();
$entity = $em->getRepository('ActPostBundle:Edition')->find($id);
$students = $em->getRepository('PersonBundle:Students')->findAll();
$students2 = $em->getRepository('PersonBundle:ForeignStudents')->findAll();
if (!$entity) {
throw $this->createNotFoundException('Unable to find Edicion entity.');
}
return $this->render('ActPostBundle:Edition:select.html.twig', array(
'entity' => $entity,
'id_actpost' => $id_actpost,
'students' => $students,
'foreignstudents' => $students2,
));
}
有关表单本身的html片段:
html fragment regarding the form itself:
<form class="form-horizontal sf_admin_form_area"
action="{{ path('edition_update_selected',
{ 'id': entity.id, 'id_actpost': id_actpost }) }}"
method="post" enctype="multipart/form-data">
<div style="margin-left: 80px" class="row-fluid">
<div class="span12">
<select name="students" multiple="multiple">
{% for s in students %}
<option {%if s in entity.students%}selected="selected"{%endif%}>
{{s}}</option>
{%endfor%}
</select>
</div>
</div>
<div class="row-fluid">
<select name="students2" multiple="multiple">
{% for s in students2 %}
<option {%if s in entity.foreignstudents%}selected="selected"
{%endif%}>{{s}}</option>
{%endfor%}
</select>
</div>
<div class="form-actions">
<button type="submit" class="btn btn-primary">
<i class="glyphicon-refresh"></i> {{'Update' | trans}}</button>
<a class="btn" href="{{ path('edition', {'id_actpost' : id_actpost }) }}">
<i class="glyphicon-ban-circle"></i> {{'Cancel' | trans }}
</a>
</div>
</form>
这是我从开头发布的链接中看到的内容: 函数来获取提交的数据并更新数据库，尽管在我设法从表单中获取数据之前，数据库部分可以一直被忽略:
and here is what I read from the link posted at the beginning: function to get the submitted data and update the database, although the database part can stay ignored until I manage to get the data from the form:
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');
$editForm = $this->createFormBuilder($defaultData)
->add('students','choice')
->add('students2', 'choice')
->getForm();
$editForm->handleRequest($request);
我想知道我所读的书是否真的是我所需要的，因为尽管我认为这可能是我做错了，所以对这件事甚至任何其他方式的见解都将受到感激.
I would like to know if what I read is actually what I need, because although I think it is I might be wrong, so any insights regarding this matter or even any other way to do it will be really appreciated.
推荐答案
您应使用symfony的表单生成器在update_selectedAction()中构建表单，例如
You should use symfony's form builder to build the form in your 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()));
}
在树枝上，即ActPostBundle:Edition:select.html.twig渲染表格
{{ form(form) }}
从评论中编辑
在您的树枝文件中渲染表格，就像
In your twig file render your form like
{{ form_errors(form) }}
{{ form_row(form.students) }}
{{ form_row(form.students2) }}
{{ form_row (form._token) }}
<input type="submit"> /* your submit button */
从评论2编辑
如果要将文本放在selectbox的value属性中，则可以使用选择字段类型
IF you want to put the text in value attribute of selectbox you can use choice field type
$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();
