Trying to achieve this structure of jsondata based on an API I am trying to connect to:
{
"VoucherDate": "2019-10-27",
"VoucherText": "string",
"VoucherType": 2,
"Rows": [{
"AccountNumber": 0,
"DebitAmount": 0,
"CreditAmount": 0,
"TransactionText": "string"
},
{
"AccountNumber": 0,
"DebitAmount": 0,
"CreditAmount": 0,
"TransactionText": "string"
}
]
}
The code I have experimented with so far, below, generates this structure. The Rows array doesn't get the same structure as above, where do I do wrong?
{
"VoucherDate": "2019-10-31",
"VoucherText": "string",
"VoucherType": 2,
"Rows": [{
"TransactionText": "test"
}, {
"AccountNumber": 1000
}, {
"DebitAmount": 1
}, {
"CreditAMount": 2
}, {
"TransactionText": "test"
}, {
"AccountNumber": 1000
}, {
"DebitAmount": 1
}, {
"CreditAMount": 2
}]
}
Php code:
$postdata = array();
$postdata["VoucherDate"] = "2019-10-31";
$postdata["VoucherText"] = "string";
$postdata["VoucherType"] = 2;
$postdata["Rows"] = array();
for ($x = 1; $x <= 10; $x++) {
$postdata["Rows"][]["TransactionText"] = "string";
$postdata["Rows"][]["AccountNumber"] = 0;
$postdata["Rows"][]["DebitAmount"] = 0;
$postdata["Rows"][]["CreditAMount"] = ;
}
echo json_encode($postdata);

You need to add all of the elements into one array before adding them to your overall data, something like....
for ($x = 1; $x <= 10; $x++) {
$postdata["Rows"][] = ["TransactionText" => "string",
"AccountNumber" => 0,
"DebitAmount" => 0,
"CreditAMount" = 2];
}
