Stack Overflow Asked by J.Wujeck on February 3, 2021
Can someone help me to return JSON data with join tables? I have two tables which are sales_details and sales_payment. I want to return the data like this:
{
"sales_id":"3",
"sales_date":"2021-01-11 23:41:58",
"sales_po":"100549",
"sales_so":"1234",
"sales_dr":"5768",
"sales_si":"1794",
"sales_company":"",
"sales_cp":"",
"sales_particulars":"Authorized Personnel Only",
"sales_media":"Sticker on Sintra",
"sales_width":"16.00",
"sales_net_amount":"8601.60",
"sales_balance":"6601.60",
},
{
"payment_amount":"1000.00",
"payment_date":"2021-01-15",
"payment_remarks":""
},
{
"payment_amount":"1000.00",
"payment_date":"2021-01-18",
"payment_remarks":""
}
This what I’ve tried:
public function get_payment_info_by_id($payment_info_id) {
$query = $this->db->query(
"SELECT *
FROM tbl_sales_details AS tsd
INNER JOIN tbl_sales_payments AS tsp ON tsp.sales_id = tsd.sales_id
WHERE tsd.sales_id = $payment_info_id");
$jsonArray = array();
foreach($query as $row) {
$jsonArrayItem = array();
$jsonArrayItem['payment_amount'] = $row['payment_amount'];
$jsonArrayItem['payment_date'] = $row['payment_date'];
$jsonArrayItem['payment_remarks'] = $row['payment_remarks'];
array_push($jsonArray, $jsonArrayItem);
}
header('Content-type: application/json');
echo json_encode($jsonArray);
}
You can use the joined query but you must look at the result you get back and work out which parts are what you need in what part of the output
I am assuming you are using PDO and have converted the query to use perpared bound parameters.
Update Ahh I see you are using MYSQLI_ and not PDO, so I have changed the database access code. That will probably fix the undefined index errors
public function get_payment_info_by_id($payment_info_id) {
$sql = "SELECT *
FROM tbl_sales_details AS tsd
INNER JOIN tbl_sales_payments AS tsp ON tsp.sales_id = tsd.sales_id
WHERE tsd.sales_id = ?";
$stmt = $this->db->prepare($sql);
$stmt->bind_param('i', $payment_info_id);
$stmt->execute();
$result = $stmt->get_result();
$last_salesid = NULL;
$t = [];
while($row = $result->fetch_assoc()) {
if ( $last_salesid != $row['sales_id'] ) {
// get sales_details columns in this case
$t[] = [
"sales_id" => $row['sales_id'],
"sales_date" => $row['sales_date'],
"sales_po" => $row['sales_po'],
"sales_so" => $row['sales_so'],
"sales_dr" => $row['sales_dr'],
"sales_si" => $row['sales_si'],
"sales_company" => $row['sales_company'],
"sales_cp" => $row['sales_cp'],
"sales_particulars" => $row['sales_particulars'],
"sales_media" => $row['sales_media'],
"sales_width" => $row['sales_width'],
"sales_net_amount" => $row['sales_net_amount'],
"sales_balance": => $row['sales_balance']
];
$last_salesid = $row['sales_id'];
}
// then get the sales_payment info
$t[] = [
'payment_amount' => $row['payment_amount',
'payment_date'] => $row['payment_date',
'payment_remarks'] => $row['payment_remarks'
];
}
header('Content-type: application/json');
echo json_encode($t);
}
