[英]how to update and delete value from array in laravel
我有一個數組 $cart 像
array:5 [▼
188 => array:17 [▼
"user_id" => "176"
"product_id" => "188"
"qty" => "2"
"date" => "03-05-2020"
"product_type" => "rear type"
"custom_color_title" => ""
"custom_color_price" => ""
"bolt_title" => ""
"bolt_price" => ""
"hub_center_rings_title" => ""
"hub_center_rings_price" => ""
"wheel_spacers_title" => ""
"wheel_spacers_price" => ""
"tire_pressure_title" => ""
"tire_pressure_price" => ""
"product_price" => 1890
"product_size" => ""
]
176 => array:17 [▼
"user_id" => ""
"product_id" => "176"
"qty" => "2"
"date" => "03-05-2020"
"product_type" => "wheel type"
"custom_color_title" => ""
"custom_color_price" => ""
"bolt_title" => ""
"bolt_price" => ""
"hub_center_rings_title" => ""
"hub_center_rings_price" => ""
"wheel_spacers_title" => ""
"wheel_spacers_price" => ""
"tire_pressure_title" => ""
"tire_pressure_price" => ""
"product_price" => 1680
"product_size" => ""
]
224 => array:17 [▶]
]
如何更新 188 position 的數量值並刪除 176 position? $cart 是 session 值存儲變量,我有$qty = $_POST['qty']; $cartid = $_POST['cartid'];
$qty = $_POST['qty']; $cartid = $_POST['cartid'];
$qty 是更新值,$cartid 是位置值。
對於更新,您可以使用它
$array[188] = [
'item_name' => 'value',
...
];
刪除你可以使用這個
unset($array[176]);
