我有一個類別表和產品表。這些類別以產品形式在下拉選擇框中列出。當我編輯產品時,產品表中保存的類別應在產品編輯表單(選定=「選定」)下的類別下拉菜單中自動選擇。如何讓symfony 2自動選擇編輯動作中的下拉字段

我已經嘗試了empty_data和empty_value,但它們不起作用。

我正在尋找2天后的解決方案,但找不到任何教程或此類示例。我將非常感激,如果有人可以參考我的教程,也可以看到下面的代碼理清問題:

控制器

<?php 

// src/Scsp/CmsBundle/Controller/ProductController.php 

namespace Scsp\CmsBundle\Controller;  
use Scsp\CmsBundle\Entity\CategoryEntity; 
use Scsp\CmsBundle\Entity\ProductEntity; 
use Scsp\CmsBundle\Form\ProductForm; 
use Symfony\Component\HttpFoundation\Response; 
use Symfony\Component\HttpFoundation\Request; 
use Symfony\Bundle\FrameworkBundle\Controller\Controller; 
use Symfony\Component\OptionsResolver\OptionsResolverInterface; 
use Symfony\Component\HttpFoundation\Session\Session; 

class ProductController extends Controller {  

    public function editAction($id, $request) { 

     $em = $this->getDoctrine()->getManager(); 
     $product = $em->getRepository('ScspCmsBundle:ProductEntity')->find($id); 

     if (!$product){ 
      throw $this->createNotFoundException('No product found for id ' . $id); 
     } 

     $productForm=new ProductForm($id); 

     $form = $this->createForm($productForm, $product, array(   
      'attr' => array('class' => 'form-horizontal') 
     )); 

     $form->handleRequest($request); 

     if ($request->isMethod('POST') && $form->isValid()) { 

       $product->setCategoryid(3);     

       $em->persist($product); 
       $em->flush();     
       $this->session->getFlashBag()->add('success', $product->getProducts() . ' successfully edited!'); 
       return $this->redirect($this->generateUrl('scsp_cms_products', array('action' => 'list', 'id' => 0)));   
     } 

     return $this->render('ScspCmsBundle:Default:form.html.twig', array(
        'form' => $form->createView(), 
        'page_title' => 'Edit product', 
        'type' => 'products', 
        'id' => $id

我看到很多事情錯在你的表單類型,然而,你在尋找的是字段定義的data選項:

->add('categoryid', 'entity', 
     array(
      'label' => false, 
      'class' => 'ScspCmsBundle:CategoryEntity', 
      'property' => 'categories', 
      'data' => $builder->getData()->getCategoryId() 
     ) 
    ) 

這至少當正常使用entity字段類型時,data字段必須包含selectvalue屬性,它是categoryId。我不知道這是否會與你當前的設置一起工作!

@Amberto我嘗試過,但仍然無法實現目標。你可以用一些例子或代碼解釋$ options-> getData() - > getCategoryId()嗎? – Salman

對不起,我的男生有一個錯字。它不是'$ options',而是'$ builder'。例如,當執行'$ this-> buildForm(new MyType(),$ data)'''',$ builder->時,執行'builder-> getData()'會爲您提供傳遞給表單的原始數據。 getData()'將完全返回傳遞'$ data'的數據。在你的情況下,一個'產品'實例;那麼你可以使用'$ data-> getCategoryId()'。 –

我是symfony 2的新手,適合您的善意幫助。我已更新原始文章中的產品表格(參見上文)。 $ builder-> getData() - > getCategoryId()返回產品表中保存的類別標識,但在下拉列表中該類別在產品的編輯操作中仍未選中。 – Salman

categoryid 

不是一個實體,所以你必須在ProductEntity添加一個名爲category財產和stablish關係多對一那裏,代碼:

/** 
* @ORM\Column(type="integer") 
* @ORM\ManyToOne(targetEntity="CategoryEntity", inversedBy="products") 
* @ORM\JoinColumn(name="categoryid", referencedColumnName="id") 
*/ 
protected $categoryid; 

必須取代

/** 
* @ORM\Column(name="categoryid", type="integer") 
*/ 
protected $categoryid; 

/** 
* @var CategoryEntity 
* @ORM\ManyToOne(targetEntity="CategoryEntity", inversedBy="products") 
* @ORM\JoinColumn(name="categoryid", referencedColumnName="id") 
*/ 
protected $category; 

//Here generate the get and the set customized 
/** 
* @return CategoryEntity 
*/ 
public function getCategory() 
{ 
    return $this->category; 
} 

/** 
* @param CategoryEntity $category 
* @return $this 
*/ 
public function setCategory($category) 
{ 
    //this is the owning side 
    //all changes will be detected 
    //in this side by doctrine 
    $category->addProduct($this); 
    $this->category= $category; 

    //The line below is important to set the categoryid 
    //field in the product table 
    $this->setCategoryid($category->getId()); 
    return $this; 
} 

現在在產品表取代:

->add('categoryid', 'entity', array(
      'label' => false, 
      'class' => 'ScspCmsBundle:CategoryEntity', 
      'property' => 'categories', 
      'data'=>$builder->getData()->getCategoryId(), 
      'attr' => array(
      ) 
       ) 
     ) 

由:

->add('category', 'entity', array(
      'label' => false, 
      'class' => 'ScspCmsBundle:CategoryEntity', 
      'property' => 'categories', 
      'attr' => array(
      ) 
       ) 
     ) 

這一切,盡情享受吧!
