I have Json Data like this :
$data = '[
{
"OrderId": "1038806370",
"qtty": "1",
"Item": "Strawberry 250 gr",
"SKU": "20091"
},
{
"OrderId": "1038806370",
"qtty": "2",
"Item": "Strawberry 130 gr",
"SKU": "20092"
},
{
"OrderId": "1038806370",
"qtty": "1",
"Item": "Strawberry 130 gr",
"SKU": "20092"
}
]';

I Want To save data from json to my table, there are table Order values [orderID,...] and OrderDetail values [orderID, SKU, Qty]
This is my code in controller
$order = json_decode($data, true);
foreach ($order as $ord) {
$check = Order::where('orderid', $ord['OrderId'])->get();
if (count($data) > 0) {
OrderDetail::firstOrCreate([
'order_id' => $ord['OrderId'],
'sku_id' => $ord['SKU'],
'qty' => $ord['qtty']
]);
} else {
Order::create([
'orderid'=> $ord['OrderId'],
]);
OrderDetail::firstOrCreate([
'order_id' => $ord['OrderId'],
'sku_id' => $ord['SKU'],
'qty' => $ord['qtty']
]);
}
}
but i dont get what i want, I get QTY of SKU 20091 is 2 but actual json data is 3

I'm not sure why you're counting the $data instead of $check variable. You don't really need the $check variable either though. I'll rewrite your code below.
$order = json_decode($data, true);
foreach ($order as $ord) {
// use EXIST query to check if Order exists or not.
if (Order::where('orderid', $ord['OrderId'])->exists())
OrderDetail::firstOrCreate([
'order_id' => $ord['OrderId'],
'sku_id' => $ord['SKU'],
'qty' => $ord['qtty']
]);
} else {
Order::create([
'orderid'=> $ord['OrderId'],
]);
OrderDetail::firstOrCreate([
'order_id' => $ord['OrderId'],
'sku_id' => $ord['SKU'],
'qty' => $ord['qtty']
]);
}
}
But your if/else could also be removed by using the firstOrCreate() method.
$orders = json_decode($data, true);
foreach ($orders as $order) {
// Get Order Model with orderid = $order['OrderId'] or create it if it doesn't exist
$model = Order::firstOrCreate([
'orderid'=> $order['OrderId']
]);
// Get OrderDetail with provided SKU, qtty and orderid or create it if it doesn't exist.
OrderDetail::firstOrCreate([
'order_id' => $model->orderid
'sku_id' => $order['SKU'],
'qty' => $order['qtty']
]);
}
You could also do it inline.
$orders = json_decode($data, true);
foreach ($orders as $order) {
OrderDetail::firstOrCreate([
'order_id' => Order::firstOrCreate(['orderid'=> $order['OrderId']])->orderid,
'sku_id' => $order['SKU'],
'qty' => $order['qtty'],
]);
}
