I am trying to integrate razorpay with php everything is ok but in prefill, I get a default value. how can I change this value to custom value?

Answer 1

In prefill you will get the value which you are given in the prefill object. Just like you passsed $amount and $razorpayOrderId you can use $name and $email etc which might be the value you get from textbox or something like that. Store those names and email in a variable and pass that into prefill.

Answer 2

you can easily change the default value by fetching those values from database or pass those values through ulr parameters as i have done in php.
get order id through url parameter or post request
$orderid = $_GET['orderid'];
run php mysql query to fetch data from database based on order id(i
have used 2 table one for payment details and another one for
userdetails)
$query = "SELECT ud.Name, ud.lname,
ud.MobileId,ud.EmailID,opd.pay_amount, opd.receipt, opd.transaction_id
FROM online_payment_details as opd
INNER JOIN userdetails as ud
ON opd.user_id=ud.UserID
WHERE order_id='$orderid';";
$result = mysqli_query($con, $query);
$row = mysqli_fetch_assoc($result);
$name = $row['Name'].' '.$row['lname'];
$razorpayOrderId = $orderid;
$amount_pay = $row['pay_amount'];
$receipt = $row['receipt'];
$transaction_id = $row['transaction_id'];
$displayAmount = $amount_pay ;
$corporateName = '';
$email = $row['EmailID'];
$contact = $row['MobileId'];
now in your data array add above variables in data array
$data = [
"key" => $keyId,
"amount" => $amount_pay,
"name" => $name,
"description" => "",
"image" => "",
"prefill" => [
"name" => $corporateName,
"email" => $email,
"contact" => $contact,
],
"notes" => [
"address" => "Hello World",
"merchant_order_id" => $transaction_id,
],
"theme" => [
"color" => "#F37254"
],
"order_id" => $razorpayOrderId,
"receipt" => $receipt,
];
and now in checkout/automatic page in block fetch values from
data array and store in data attribute as below
<script
src="https://checkout.razorpay.com/v1/checkout.js"
data-key="<?php echo $data['key']?>"
data-amount="<?php echo $data['amount']?>"
data-currency="INR"
data-name="<?php echo $data['name']?>"
data-image="<?php echo $data['image']?>"
data-description="<?php echo $data['description']?>"
data-prefill.name="<?php echo $data['prefill']['name']?>"
data-prefill.email="<?php echo $data['prefill']['email']?>"
data-prefill.contact="<?php echo $data['prefill']['contact']?>"
data-notes.shopping_order_id="<?php echo $data['receipt']?>"
data-order_id="<?php echo $data['order_id']?>"
<?php if ($displayCurrency !== 'INR') { ?> data-display_amount="<?php echo $data['display_amount']?>" <?php } ?>
<?php if ($displayCurrency !== 'INR') { ?> data-display_currency="<?php echo $data['display_currency']?>" <?php } ?>
>
</script>
