[英]Get Product Category Name In Module using Prestashop 1.6
我為 prestashop 創建了自己的模塊(目前非常基本)。
我想為產品添加一些自定義(類似於 Attribute Wizard Pro )最終目標:我希望我的模塊根據產品所在的類別在產品頁面上顯示一個小表格(每個類別的表格略有不同)-並且在購買產品時將保存該表格的結果。
我想把表單放在 RightColumnProduct 中——我可以通過在這個鈎子中訪問它並調用我創建的 TPL 來做到這一點。
public function hookDisplayRightColumnProduct()
{
/* Place your code here. */
/*Get the Current Category name to see which TPL to show*/
return $this->display(__FILE__,'views/hooks/mytpl.tpl');
}
我需要做的是訪問當前產品的類別名稱,但事實證明這很難做到。
我嘗試了各種解決方案,但都沒有成功。
此代碼段將顯示默認產品類別的名稱。
$product = $this->context->controller->getProduct(); $category = new Category((int)$product->id_category_default, (int)$this->context->language->id); echo $category->name;
鈎子DisplayRightColumnProduct()
沒有任何參數作為參數傳遞給它,因此要獲取類別名稱或任何其他信息,我們必須再次重建用戶正在訪問的產品的所有數據。 我們還必須了解一些產品的屬性:
產品可以有多個類別,因此用戶可以通過不同的路徑進入產品頁面。
該產品也可以直接訪問,在這種情況下,我們沒有關於應該顯示哪個類別名稱的信息。
因此,在 DisplayRightColumnProduct 函數中,我將執行以下步驟:
//retrieve the product id from the $_GET, and instanciate the object to have it ready for any functionality we have to create.
$product = new Product(Tools::getValue('id_product'), false, $this->context->cookie->id_lang);
//by simulating what the ProductController does we are going to get the category of the product
$id_category = false;
if (isset($_SERVER['HTTP_REFERER']) && $_SERVER['HTTP_REFERER'] == Tools::secureReferrer($_SERVER['HTTP_REFERER']) // Assure us the previous page was one of the shop
&& preg_match('~^.*(?<!\/content)\/([0-9]+)\-(.*[^\.])|(.*)id_(category|product)=([0-9]+)(.*)$~', $_SERVER['HTTP_REFERER'], $regs))
{
// If the previous page was a category and is a parent category of the product use this category as parent category
$id_object = false;
if (isset($regs[1]) && is_numeric($regs[1]))
$id_object = (int)$regs[2];
elseif (isset($regs[5]) && is_numeric($regs[5]))
$id_object = (int)$regs[6];
if ($id_object)
{
$referers = array($_SERVER['HTTP_REFERER'],urldecode($_SERVER['HTTP_REFERER']));
if (in_array($this->context->link->getCategoryLink($id_object), $referers))
$id_category = (int)$id_object;
elseif (isset($this->context->cookie->last_visited_category) && (int)$this->context->cookie->last_visited_category && in_array($this->context->link->getProductLink($id_object), $referers))
$id_category = (int)$this->context->cookie->last_visited_category;
}
}
//else if we have accessed the product page directly, we have just one way to get the category and it's to retrieve the default from the product object.
if (!$id_category || !Category::inShopStatic($id_category, $this->context->shop) || !Product::idIsOnCategoryId((int)$product->id, array('0' => array('id_category' => $id_category))))
$id_category = (int)$product->id_category_default;
$category = new Category((int)$id_category, (int)$this->context->cookie->id_lang);
//now we have the category object at our disposal so to get the name, we can simply refer to the property:
return $category->name;
