Question

我有一个productRepositiry模型，用于在数据库中创建产品

class ProductRepository extends EntityRepository{
public function createProduct($productDetails) {
     $this->_em->persist($productDetails);
     $this->_em->flush();
     log_message("info","Product {$productDetails->name} created.");
     print "Product {$productDetails->name} created.<br/><br/><br/>";
     return $productDetails;
}

procuct controller，使用post获取值并将值传递给productRepositiry

public function addProduct(){
    if(! $this->session->userdata('user_id')){
        redirect('welcome');
    }else{
        $productDetails = new Entity\Product;
        $productDetails->market = $this->input->post('mid');
        $productDetails->name =  $this->input->post('product_name');
        $productDetails->price =  $this->input->post('product_price');
        $productDetails->discount =  $this->input->post('product_discount');
        $productDetails->category =  $this->input->post('product_cat');
        $productDetails->forwho =  $this->input->post('product_for');
        $productDetails->desc =  $this->input->post('product_desc');
        $productDetails->created =  new DateTime("now");
        ![enter image description here][1]

        $productRepository = $this->doctrine->em->getRepository('Entity\Product');
        if($productRepository) echo "found;";
        $createdProduct = $productRepository->createProduct($productDetails);
        echo "Level 2 -> ";

        $p = $productRepository->findBy(array('id' => $createdProduct->id));
        echo "\n" . $p[0]->id. " => " . $p[0]->name;
    }
}

错误消息::消息：spl_object_hash（）期望参数1为对象，给定字符串

Answer 1

我不知道实体Product的确切结构是什么。但我会要求您验证Product是否与其他实体有某种关系，但您可能将这些实体作为字符串而不是实际实体传递。

您可以使用find函数获取实体。
