Question

I am trying ti insert JSON array into my mysql database.Here I give format for that
array ${
"customer_id": "1",
"products":[ {
"product_id": "1",
"product_qty": "2"
}, {
"product_id": "2",
"product_qty": "4"
}, {
"product_id": "3",
"product_qty": "12"
}, {
"product_id": "4",
"product_qty": "22"
}],
"order_totalamount": "100"
}
I tried insert query as below:
foreach($data as $item) {
//insert into mysql table
$sql = "insert into `order`(cm_id,product_id,product_quantity,order_totalamount,order_id,order_date) values ($cus_id,$item[product_id],$item[product_qty],$order_totalamount,$cus_id,CURDATE())";
also decode JSON data, and foreach loop

Answer 1

json_decode the string and iterate through the array of products and insert them one by one.
$data = json_decode($json_string);
$customer_id = $data->customer_id;
foreach($data->products as $product) // its a array of products you showed in json
{
// insert code here for mysql insert
}

try below code :
$res = '{
"customer_id": "1",
"products":[ {
"product_id": "1",
"product_qty": "2"
}, {
"product_id": "2",
"product_qty": "4"
}, {
"product_id": "3",
"product_qty": "12"
}, {
"product_id": "4",
"product_qty": "22"
}],
"order_totalamount": "100"
}';
$data=json_decode($res);
foreach ($data->products as $item)
$sql = "insert into `order`(cm_id,product_id,product_quantity,order_totalamount,order_id,order_date ) values ($data->customer_id,$item->product_id,$item->product_qty,$data->order_totalamount,$data->customer_id,CURDATE())";
