我正在建立一个界面,使办公室中的人员可以编辑特定记录的详细信息。 目前,我有这样的表格:
view.html.twig
<!-- Modal Windows: Edit Instructor Personal Details -->
<div id="editPersonal" style="display:none;">
<div class="modal-head">
<h2>Edit Personal Details For: <font-color="red !important">{{instructor.firstName}} {{instructor.surname}}</font></h2>
</div>
<div class="modal-body">
<form action="#" method="post" {{ form_enctype(ipde) }} id="editPersonalDetails" class="modaledit">
<table class="modalform-col1">
<tbody>
<tr class="hidden">
<th>{{ form_label(ipde.id, 'ID*', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.id) }}
{{ form_widget(ipde.id, { 'attr': {'class': 'textfield'}}) }}
</td>
</tr>
<tr>
<th>{{ form_label(ipde.firstName, 'First Name*', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.firstName) }}
{{ form_widget(ipde.firstName, { 'attr': {'class': 'text'}}) }}
</td>
</tr>
<tr>
<th>{{ form_label(ipde.surname, 'Surname*', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.surname) }}
{{ form_widget(ipde.surname, { 'attr': {'class': 'text'}}) }}
</td>
</tr>
<tr>
<th>{{ form_label(ipde.address1, 'Address Line 1*', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.address1) }}
{{ form_widget(ipde.address1, { 'attr': {'class': 'text'}}) }}
</td>
</tr>
<tr>
<th>{{ form_label(ipde.address2, 'Address Line 2', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.address2) }}
{{ form_widget(ipde.address2, { 'attr': {'class': 'text'}}) }}
</td>
</tr>
<tr>
<th>{{ form_label(ipde.town, 'Town*', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.town) }}
{{ form_widget(ipde.town, { 'attr': {'class': 'text'}}) }}
</td>
</tr>
<tr>
<th>{{ form_label(ipde.county, 'County*', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.county) }}
{{ form_widget(ipde.county, { 'attr': {'class': 'text'}}) }}
</td>
</tr>
<tr>
<th>{{ form_label(ipde.postcode, 'Postcode*', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.postcode) }}
{{ form_widget(ipde.postcode, { 'attr': {'class': 'text'}}) }}
</td>
</tr>
<tr>
<th>{{ form_label(ipde.email, 'Email*', { 'attr': {'class': 'title'} }) }}</th>
<td>
{{ form_errors(ipde.email) }}
{{ form_widget(ipde.email, { 'attr': {'class': 'text'}}) }}
</td>
</tr>
</tbody>
</table>
</div>
<div class="modal-footer">
<div class="modal-placeright">
<a href="#close" rel="modal:close" class="closebutton">Close Without Saving</a>
<input type="submit" value="Save Changes" id="savebuttonpr" class="savebutton" />
{{ form_rest(ipde) }}
</div>
</div>
</div>
我的控制器看起来像这样:
DefaultController.php
<?php
namespace PCUK\InstructorBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use PCUK\InstructorBundle\Form\IpdeType;
use PCUK\InstructorBundle\Form\IrType;
use PCUK\InstructorBundle\Form\BaType;
use Symfony\Component\HttpFoundation\Request;
class DefaultController extends Controller
{
public function viewAction($instructor, Request $request)
{
// Database connection
$insrep = $this->getDoctrine()->getManager();
// Get Instructor from Entity for Form use
$instructorQ = $insrep->getRepository('InstructorBundle:MapInstructors')->find($instructor);
// Get Shared Branches from Entity for Form use
$instructorS = $insrep->getRepository('InstructorBundle:MapInstructorShared')->find($instructor);
// Generate Form to edit Instructor Personal Details
$ipde = $this->createForm( new IpdeType(), $instructorQ);
// Handle Form submission to edit Instructor Personal Details
if ($request->getMethod() == 'POST') {
$ipde->bind($request);
if ($ipde->isValid()) {
// perform some action, such as saving the task to the database
//if ($this->request->isXmlHttpRequest()){
//return data ajax requires.
//}
$em = $this->getDoctrine()->getManager();
$em->persist($ipde);
$em->flush();
return $this->redirect($this->generateUrl('task_success'));
}
}
// Generate Form to edit Instructor Records
$ir = $this->createForm( new IrType(), $instructorQ);
// Generate Form to edit Instructor Records
$ba = $this->createForm( new BaType(), $instructorS);
// Return data to view
return $this->render('InstructorBundle:Default:view.html.twig', array(
'ipde' => $ipde->createView(),
'ir' => $ir->createView(),
'ba' => $ba->createView()
));
}
}
但是,当我提交表单时,出现以下错误:
“在链配置的名称空间PCUK \\ InstructorBundle \\ Entity中找不到类'Symfony \\ Component \\ Form \\ Form'”
我之前已经构建了一个Symfony2项目,并且已针对当前项目引用了该项目,以查看是否包含了Symfony\\Component\\Form\\Form
,如果这确实是问题所在。
发生了什么?
您正在坚持的$ipde
恰好是形式而不是实体!
那可能是错误的根源。
您所有的* Type()类中都有“ use”语句吗? 我想应该是
use Symfony\Component\Form\AbstractType;
AbstractType具有使用Form命名空间的功能。
