我为Prestashop创建了一个自定义控制器。它是一个简单的任务: 1.创建一个新的购物车,如果它没有创建(工作正常) 2.从数据库中获取属性ID(正常工作) 3.分配自定义(一个文本字段) 4.将此产品添加到购物车。
我目前的代码:
$idProduct = 1; // for me it's always one
$qty= 1; // always add one item
$text = (string)Tools::getValue('textField9'); // string of text customization
$attribute = (int)Tools::getValue('sel_combination'); // atribute combination ID
// get cart id if exists
if ($this->context->cookie->id_cart)
{
$cart = new Cart($this->context->cookie->id_cart);
}
// create new cart if needed
if (!isset($cart) OR !$cart->id)
{
$cart = new Cart();
$cart->id_customer = (int)($this->context->cookie->id_customer);
$cart->id_address_delivery = (int) (Address::getFirstCustomerAddressId($cart->id_customer));
$cart->id_address_invoice = $cart->id_address_delivery;
$cart->id_lang = (int)($this->context->cookie->id_lang);
$cart->id_currency = (int)($this->context->cookie->id_currency);
$cart->id_carrier = 1;
$cart->recyclable = 0;
$cart->gift = 0;
$cart->add();
$this->context->cookie->id_cart = (int)($cart->id);
$cart->update();
}
// get product to add into cart
$productToAdd = new Product(1, true, (int)($this->context->cookie->id_lang));
// default attributes
// $default_id_product_attribute = Product::getDefaultAttribute($productToAdd->id, $minimumQuantity);
// assign real attributes
$attributes = $attribute;
$cart->update();
// add customizatated text
$customization = $this->context->cart->addTextFieldToProduct((int)($idProduct), 9, Product::CUSTOMIZE_TEXTFIELD, $text );
$exising_customization = Db::getInstance()->executeS('SELECT id_customization FROM '._DB_PREFIX_.'customized_data ORDER BY id_customization DESC LIMIT 0,1');
$customization = $exising_customization[0]['id_customization'];
Db::getInstance()->execute('UPDATE ps_customization SET in_cart = 1, id_product_attribute = '.$attributes.' WHERE id_customization = ' .$customization);
// add product to cart
$cart->updateQty($qty, (int)($idProduct), (int)($attributes), (int)($customization), Tools::getValue('op', 'up'));
$prods = $cart->getProducts(true);
print_r ($prods[0]['id_customization']);
// update cart
$cart->update();
创建购物车并添加产品。购物车说,有一种产品 - 但它没有显示出来。重新加载上述代码后,购物车显示2项具有适当自定义数据的项目。
从我能找到的问题出现在定制中。第一次没有分配($ cart-> getProducts(true);显示[' id_customization']为null),但第二次一切正常。即使第一个产品也是固定的。

我设法解决了这个问题。
创建购物车的正确方法:
if (!$this->context->cart->id)
{
if (Context::getContext()->cookie->id_guest)
{
$guest = new Guest(Context::getContext()->cookie->id_guest);
$this->context->cart->mobile_theme = $guest->mobile_theme;
}
$this->context->cart->add();
if ($this->context->cart->id)
$this->context->cookie->id_cart = (int)$this->context->cart->id;
}
添加自定义
$this->product = new Product(1, true, (int)($this->context->cookie->id_lang));
$authorized_text_fields = array();
if (!$field_ids = $this->product->getCustomizationFieldIds())
return false;
foreach ($field_ids as $field_id)
if ($field_id['type'] == Product::CUSTOMIZE_TEXTFIELD)
$authorized_text_fields[(int)$field_id['id_customization_field']] = 'textField'.(int)$field_id['id_customization_field'];
$indexes = array_flip($authorized_text_fields);
foreach ($_POST as $field_name => $value)
if (in_array($field_name, $authorized_text_fields) && !empty($value))
{
if (!Validate::isMessage($value))
$this->errors[] = Tools::displayError('Invalid message');
else
$this->context->cart->addTextFieldToProduct($this->product->id, $indexes[$field_name], Product::CUSTOMIZE_TEXTFIELD, $value);
}
else if (in_array($field_name, $authorized_text_fields) && empty($value))
$this->context->cart->deleteCustomizationToProduct((int)$this->product->id, $indexes[$field_name]);
获取自定义
$texts = $this->context->cart->getProductCustomization($this->product->id, Product::CUSTOMIZE_TEXTFIELD, true);
$text_fields = array();
foreach ($texts as $text_field)
$text_fields['textFields_'.$this->product->id.'_'.$text_field['index']] = str_replace('<br />', "\n", $text_field['value']);

验证购物车最简单:
// Validate the object cart
$this->context->cart->save();
$this->context->cookie->id_cart = (int)$this->context->cart->id;
如果存在,则save()方法会更新购物车,如果不存在则创建新购物。 然后强制cookie具有相同的ID。
