database is not updating the values after successful transaction through payment gateway - php

Question

My website's framework is in CodeIgniter. I have integrated instamojo payment gateway in it. The query inserting the payment id but after successful payment not updating the column value of status to 1 from 0,
This is the block code of paymentcontroller.php
public static function userDataUpdate($trx)
{
$general = getGeneral();
$data = Deposit::where('trx', $trx)->first();
if ($data->status == 0) {
$data->status = 1;
$data->save();
$user = User::find($data->user_id);
$wallet = $user->wallet;
$wallet->balance += $data->amount;
$wallet->save();
$transaction = new Transaction();
$transaction->user_id = $data->user_id;
$transaction->amount = $data->amount;
$transaction->post_balance = $wallet->balance;
$transaction->charge = $data->charge;
$transaction->trx_type = '+';
$transaction->details = 'Deposited via ' . $data->gatewayCurrency()->name;
$transaction->trx = $data->trx;
$transaction->save();
$adminNotification = new AdminNotification();
$adminNotification->user_id = $user->id;
$adminNotification->title = 'Deposit succeeded via '.$data->gatewayCurrency()->name;
$adminNotification->click_url = urlPath('admin.deposit.successful');
$adminNotification->save();
notify($user, 'DEPOSIT_COMPLETE', [
'method_name' => $data->gatewayCurrency()->name,
'method_currency' => $data->method_currency,
'method_amount' => showAmount($data->final_amo),
'amount' => showAmount($data->amount),
'charge' => showAmount($data->charge),
'currency' => $general->cur_text,
'rate' => showAmount($data->rate),
'trx' => $data->trx,
'post_balance' => showAmount($wallet->balance)
]);
}
}
This is the code of processcontroller.php
<?php
namespace App\Http\Controllers\Gateway\Instamojo;
use App\Models\Deposit;
use App\Http\Controllers\Gateway\PaymentController;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
class ProcessController extends Controller
{
/*
* Instamojo Gateway
*/
public static function process($deposit)
{
$basic = getGeneral();
$instaMojoAcc = json_decode($deposit->gatewayCurrency()->gateway_parameter);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://test.instamojo.com/api/1.1/payment-requests/');
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt(
$ch,
CURLOPT_HTTPHEADER,
array(
"X-Api-Key:$instaMojoAcc->api_key",
"X-Auth-Token:$instaMojoAcc->auth_token"
)
);
$payload = array(
'purpose' => 'Payment to ' . $basic->sitename,
'amount' => round($deposit->final_amo,2),
'buyer_name' => $deposit->user->username,
'redirect_url' => route('user.deposit.history'),
'webhook' => route('ipn.'.$deposit->gateway->alias),
'email' => $deposit->user->email,
'btc_wallet' => $deposit->trx,
'send_email' => true,
'allow_repeated_payments' => false
);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($payload));
$response = curl_exec($ch);
curl_close($ch);
$res = json_decode($response);
if (#$res->success) {
if(!#$res->payment_request->id){
$send['error'] = true;
$send['message'] = "Response not given from API. Please re-check the API credentials.";
}else{
$deposit->btc_wallet = $res->payment_request->id;
$deposit->save();
$send['redirect'] = true;
$send['redirect_url'] = $res->payment_request->longurl;
$send['btc_wallet'] = $deposit->trx;
}
} else {
$send['error'] = true;
$send['message'] = "Credentials mismatch. Please contact with admin";
}
return json_encode($send);
}
public function ipn(Request $request)
{
//$this->customLog($request->all(),'Instamojo',true);
$deposit = Deposit::where('btc_wallet', $_POST['payment_request_id'])->orderBy('id', 'DESC')->first();
$instaMojoAcc = json_decode($deposit->gatewayCurrency()->gateway_parameter);
$deposit->detail = $request->all();
$deposit->save();
$imData = $_POST;
$macSent = $imData['mac'];
unset($imData['mac']);
ksort($imData, SORT_STRING | SORT_FLAG_CASE);
$mac = hash_hmac("sha1", implode("|", $imData), $instaMojoAcc->salt);
if ($macSent == $mac && $imData['status'] == "Credit" && $deposit->status == '0') {
PaymentController::userDataUpdate($deposit->trx);
}
}
}
I am unable to find out why the query is not updating the status of the transaction in mysqli.
