creating json file from database - php

Question

I need to create this json in the following format
{
"status": true,
"message": "",
"orders": [
{
"orderId": "1",
"orderDate": "1/06/2021",
"products": [
{
"productName": "Product 1",
"quantity": "1",
"price": "5.00"
},
{
"productName": "Product 2",
"quantity": "2",
"price": "24.00"
},
{
"productName": "Product 3",
"quantity": "1",
"price": "6.50"
}
]
},
{
"orderId": "2",
"orderDate": "2/06/2021",
"products": [
{
"productName": "Product 1",
"quantity": "1",
"price": "3.00"
},
{
"productName": "Product 2",
"quantity": "1",
"price": "11.50"
}
]
},
{
"orderId": "3",
"orderDate": "03/05/2021",
"products": [
{
"productName": "Product 1",
"quantity": "1",
"price": "3.00"
},
{
"productName": "Product 2",
"quantity": "1",
"price": "11.50"
}
]
}
]
}
This is my code that I use to retrive the information from the database
$stmt = $con->prepare("SELECT OrderID, OrderDate, ProductName, ProductQty, ProductPrice FROM Orders where CustomerID = ?");
$stmt->bind_param("s", $CustomerID);
$stmt->execute();
$stmt->store_result();
$stmt->bind_result($OrderID, $OrderDate, $ProductName, $ProductQty, $ProductPrice);
while($stmt->fetch()) {
$message[] = array(
"status" => true,
"message" => "",
"orders" => array(
array(
"orderId" => "$OrderID",
"orderDate" => "$OrderDate",
"products" => array(
array(
"productName" => "$ProductName",
"quantity" => "$ProductQty",
"price" => "$ProductPrice"
),
)
)
)
);
}
$json = $message;
header('content-type: application/json');
echo json_encode($json);
This is how the information from the database displays. I do not know how to show the information about the products correctly. Can anyone show me how to do it in the format that I require in php? Thanks in advance for any help.
[
{
"status": true,
"message": "",
"orders": [
{
"orderId": "1",
"orderDate": "1/06/2021",
"products": [

"productName": "620",
"quantity": "1",

},

}
]
},

}

}

},
{

}
]
}
]
}
]

Answer 1

You are repeating the orders structure which you shouldn't. That's why you get the wrong structure. This is what you should do instead (your code, modified):
// specify your return response array only once
$message = array(
"status" => true,
"message" => "",
"orders" => array();
);
$stmt = $con->prepare("SELECT OrderID, OrderDate, ProductName, ProductQty, ProductPrice FROM Orders where CustomerID = ?");
$stmt->bind_param("s", $CustomerID);
$stmt->execute();
$stmt->store_result();
$stmt->bind_result($OrderID, $OrderDate, $ProductName, $ProductQty, $ProductPrice);
while($stmt->fetch()) {
// and fill its "orders" member with your orders list
$message["orders"][] = array(
"orderId" => "$OrderID",
"orderDate" => "$OrderDate",
"products" => array(
array(
"productName" => "$ProductName",
"quantity" => "$ProductQty",
"price" => "$ProductPrice"
),
)
);
}
$json = $message;
header('content-type: application/json');
echo json_encode($json);

You can try like below
const data = [
{
"status": true,
"message": "",
"orders": [
{
"orderId": "1",
"orderDate": "1/06/2021",
"products": [
{
"productName": "620",
"quantity": "1",
"price": "5.00"
}
]
}
]
},
{
"status": true,
"message": "",
"orders": [
{
"orderId": "1",
"orderDate": "1/06/2021",
"products": [
{
"productName": "240",
"quantity": "1",
"price": "5.00"
},
{
"productName": "270",
"quantity": "1",
"price": "10.00"
}
]
}
]
},
{
"status": true,
"message": "",
"orders": [
{
"orderId": "1",
"orderDate": "1/06/2021",
"products": [
{
"productName": "30",
"quantity": "1",
"price": "5.00"
}
]
}
]
},
{
"status": true,
"message": "",
"orders": [
{
"orderId": "1",
"orderDate": "1/06/2021",
"products": [
{
"productName": "280",
"quantity": "1",
"price": "5.00"
}
]
}
]
},
{
"status": true,
"message": "",
"orders": [
{
"orderId": "1",
"orderDate": "1/06/2021",
"products": [
{

}
]
},
{
"status": false,
"message": "",
"orders": [
{
"orderId": "1",
"orderDate": "1/06/2021",

}
]
},

}
]
}
]
}
];
const resutl = data.reduce((acc, cur) => {
const key = cur.status ? "successItems" : "failureItems";
if (acc[key]) {
return {
...acc,
[key]: {
status: cur.status,
messgae: '',
orders: [
...acc[key].orders,
...cur.orders
]
}
}
} else {
return {
...acc,
[key]: {
status: cur.status,
messgae: '',
orders: [
...cur.orders
]
}
}
}
}, {});
console.log('resutl', resutl);
console.log('resutl', Object.values(resutl));
