我在SESSION的购物篮里有一些商品。
每件商品可能是一家商店的，另一件商品可能是另一家商店的。
我想当客户点击在篮子中的每个商店项目列表创建因素按钮。我如何删除或取消我的购物篮中具有相同shopid的一些商品，并且客户单击具有此shopid的商店的创建因子。

你可以看到一些项目是不同的shopid，它不是排序。
shopid=4的项目? 使用一个简单的循环和PHP内置数组函数:
$deleteShopId = 4;
$test = Array('customer' => Array('basket' => Array(
'9_2' => Array
(
"row" => "0",
'item' => 'cd',
'count' => '1',
'sale_start_date' => '1391-12-25 19:27:56',
'sale_end_date' => '1392-04-20 19:27:49',
'sale_price' => '40500',
'price' => '54564',
'id' => '999035',
'shopid' => '4'
),
'999_17' => Array
(
'row' => '1',
'item' => 'car',
'count' => '1',
'sale_start_date' => '0000-00-00 00:00:00',
'sale_end_date' => '0000-00-00 00:00:00',
'sale_price' => '0',
'price' => '520000',
'id' => '999039',
'code' => 'b125nh',
'shopid' => '6'
),
'9_3' => Array
(
'row' => '2',
'item' => 'book',
'count' => '1',
'sale_start_date' => '0000-00-00 00:00:00',
'sale_end_date' => '0000-00-00 00:00:00',
'sale_price' => '0',
'price' => '520000',
'id' => '999039',
'code' => 'b125nh',
'shopid' => '4'
),
'10_5' => Array
(
'row' => '2',
'item' => 'dvd',
'count' => '1',
'sale_start_date' => '0000-00-00 00:00:00',
'sale_end_date' => '0000-00-00 00:00:00',
'sale_price' => '0',
'price' => '520000',
'id' => '999039',
'code' => 'b125nh',
'shopid' => '5'
)
)
)
);
foreach($test['customer']['basket'] as $something => $somethingElse){
$temp = array_search($deleteShopId,$somethingElse);
if($temp !== FALSE && $temp =='shopid'){
unset($test['customer']['basket'][$something]);
}
}
var_dump($test['customer']['basket']);
array(2) {
["999_17"]=>
array(10) {
["row"]=>
string(1) "1"
["item"]=>
string(3) "car"
["count"]=>
string(1) "1"
["sale_start_date"]=>
string(19) "0000-00-00 00:00:00"
["sale_end_date"]=>
string(19) "0000-00-00 00:00:00"
["sale_price"]=>
string(1) "0"
["price"]=>
string(6) "520000"

}

}
}
当然要将$something和$somethingElse重命名为更有意义的名称。我不知道它们代表什么。
$shop = 4;
$_SESSION['customer']['basket'] = array_filter(
$_SESSION['customer']['basket'],
function (array $item) use ($shop) { return $item['shopid'] != $shop; }
);
您可能需要这样做:
function selectUniqueByAttribute($array, $attributeName)
{
$keysArray = array();
foreach($array as $key=>$value){
$keysArray[$value[$attributeName]] = $key;
}
$output = array();
foreach($keysArray as $key){
$output[$key] = $array[$key];
}
return $output;
}
$data = array('customer' => array(
'basket' => array(
'9_2' => array
(
"row" => "0",
'item' => 'cd',
'count' => '1',
'sale_start_date' => '1391-12-25 19:27:56',
'sale_end_date' => '1392-04-20 19:27:49',
'sale_price' => '40500',
'price' => '54564',
'id' => '999035',
'shopid' => '4'
),
'999_17' => array
(
'row' => '1',
'item' => 'car',
'count' => '1',
'sale_start_date' => '0000-00-00 00:00:00',
'sale_end_date' => '0000-00-00 00:00:00',
'sale_price' => '0',
'price' => '520000',
'id' => '999039',
'code' => 'b125nh',
'shopid' => '6'
),
'9_3' => array
(
'row' => '2',
'item' => 'book',
'count' => '1',
'sale_start_date' => '0000-00-00 00:00:00',
'sale_end_date' => '0000-00-00 00:00:00',
'sale_price' => '0',
'price' => '520000',
'id' => '999039',
'code' => 'b125nh',
'shopid' => '4'
),
'10_5' => array
(
'row' => '2',
'item' => 'dvd',
'count' => '1',
'sale_start_date' => '0000-00-00 00:00:00',
'sale_end_date' => '0000-00-00 00:00:00',
'sale_price' => '0',
'price' => '520000',
'id' => '999039',
'code' => 'b125nh',
'shopid' => '5'
)
)
)
);
$filteredArray = array(
'customer' => array(
'basket' => selectUniqueByAttribute($data['customer']['basket'], 'shopid')
)
);
print_r('<pre>');
print_r($filteredArray);
die();
您可以递归地搜索您的篮子并获得具有特定shop_id的所有键。例如这个函数:
function array_search_recursive($needle, $haystack, $key = false, $path = null) {
if(empty($path['level'])) $path['level'] = 0;
if(empty($path['work'])) $path['work'] = array();
if(!is_array($haystack)) $haystack = array();
foreach($haystack as $_key => $_value) {
if(is_scalar($_value) && $_value == $needle && !$key) {
$path['work'][$path['level']] = $_key;
$path['found'][] = $path['work'];
} elseif(is_scalar($_value) && $_value == $needle && $_key == $key) {
$path['work'][$path['level']] = $_key;
$path['found'][] = $path['work'];
} elseif (is_array($_value)) {
$path['work'][$path['level']] = $_key;
$path['level'] += 1;
$path = array_search_recursive($needle, $_value, $key, $path);
}
}
array_splice($path['work'], $path['level']);
$path['level'] -= 1;
if($path['level'] == '-1') {
return $path['found'];
} else return $path;
}
将调用array_search_recursive('4', $_SESSION['customer']['basket'])返回
Array
(
[0] => Array
(
[0] => 9_2
[1] => shopid
)
[1] => Array
(
[0] => 9_3
[1] => shopid
)
)
然后您可以循环您的篮子并删除这些键。还有其他方法可以做到这一点，例如使用array_filter，就像deze建议的那样。
取消键设置的代码:
$keys = array_search_recursive('4', $_SESSION['customer']['basket']);
if(!empty($keys)) {
foreach($keys as $item) {
unset($_SESSION['customer']['basket'][$item[0]]);
}
}
