我有以下代码:
public function addAction(Request $request){
//Get submited data
// Get Value from session
$sessionVal = $this->get('session')->get('aBasket');
// Append value to retrieved array.
$aBasket = $request->request->all();
if(count($sessionVal) > 0) {
foreach ($sessionVal as $key=>$value) {
if($aBasket['product_id'] == $sessionVal[$key]['product_id'])
{
$sessionVal[$key]['product_quantity'] = $sessionVal[$key]['product_quantity'] + $aBasket['product_quantity'];
$this->get('session')->set('aBasket', $sessionVal);
}
else
{
$sessionVal[] = $aBasket;
$this->get('session')->set('aBasket', $sessionVal);
}
}
}
else
{
$sessionVal[] = $aBasket;
$this->get('session')->set('aBasket', $sessionVal);
}
// Set value back to session
return $this->redirect($this->generateUrl('shop_desktop_homepage'));
}
想法是增加现有产品的数量,如果id未对应,则添加它们。现在数量正确添加,但产品也被添加。现有解决方案?请帮帮我......

您可以简化代码,我猜您的会话数组看起来像
array(
'11' =>array('id'=>'11','title'=>'some product','product_quantity'=>2),
'12' =>array('id'=>'12','title'=>'some product','product_quantity'=>1),
'13' =>array('id'=>'13','title'=>'some product','product_quantity'=>3),
);
您的购物车数组中的键将是产品ID,因此现在在下面的代码中不会有重复的产品数据我已经删除了foreach
循环而我只使用了if if if(isset($sessionVal[$aBasket['product_id']]))
是否产品ID已经存在于购物车数组中,只需将产品ID代替密钥,例如if(isset($sessionVal['11']))
如果存在,则将数量增加1,如果不存在则将产品插入购物车数组
public function addAction( Request $request ) {
$sessionVal = $this->get( 'session' )->get( 'aBasket' );
$aBasket = $request->request->all();
if(isset($sessionVal[$aBasket['product_id']])){
$sessionVal[$aBasket['product_id']]['product_quantity'] += 1;
}else{
$sessionVal[$aBasket['product_id']]= array(
'id'=>$aBasket['product_id'],
'product_quantity' => 1,
'other_info' => '...'
);
}
$this->get( 'session' )->set( 'aBasket', $sessionVal );
return $this->redirect( $this->generateUrl( 'shop_desktop_homepage' ) );
}
