Hi,

It would be helpful to know what language you are building on. I'm going to assume PHP.

If I udnerstand your question correctly, you have fields such as "First Name", "Last Name", "Birth Day", etc that you want to make sure that they are filling out?

Well,

You can verify the name of your user and see if it matches the name on the credit card but i think your asking more of a fundamental question than that.

In your HTML, you should have a <form> tag that posts to your PHP. Inside the form tag, you should have all your inputs including your credit card number input, etc.

For each input, assign a name to the input. For example, if i wanted the users phone number, I would make an input such as:

<input type="text" name="phone_number" value=""  />

Then to get this value in the PHP, you would use $_POST["phone_number"] (Notice how phone_number is the NAME of the input. You can make the name of the input ANYTHING you want.)

So to use this value, you can assign it to a PHP variable:

$phone_number = $_POST["phone_number"];

finally, you can run some checks on the data:

if( trim($phone_number) == "" )

{

  echo "I'm sorry, but you forgot to fill out your phone number. Please go back and try again.";

}

else

{

  //Continue checking other fields or even charge the credit card now!

}

I hope this helps!

thanks for your suggestion. i want to show my code to you that as follows

<?php
require_once 'anet_php_sdk/AuthorizeNet.php'; // Include the SDK you downloaded in Step 2
$api_login_id = 'my id';
$transaction_key = 'my key';
$amount = $_REQUEST['amount'];
$product_name = $_REQUEST['pro_name'];
$quantity = $_REQUEST['quan'];
$email = $_REQUEST['email'];
$fp_timestamp = time();
$fp_sequence = "123" . time(); // Enter an invoice or other unique number.
$fingerprint = AuthorizeNetSIM_Form::getFingerprint($api_login_id,
$transaction_key, $amount, $fp_sequence, $fp_timestamp)
?>

<h1>Review your order</h1>
<label>Email : </label><label><?php echo $email ?></label><br />
<label>Name of the Product : </label><label><?php echo $product_name ?></label><br />
<label>Product Quantity : </label><label><?php echo $quantity ?></label><br />

I would suggest validating your inputs BEFORE you post your information to https://test.authorize.net/gateway/transact.dll

Then, if there is an error, you just give the user the error and have them resolve the problem before you continue.

so maybe, have a conditional branch that checks for errors and at the end of the branch, you can put the "pay now" button.

if( first name is not ok)

{

  echo out an error to user. Have them go back and fix it.

}

else if (last name is not ok)

{

  echo out an error to user. Have them go back and fix it.

}

else

{

  pay now button!

}

If you have a database, you can look inot how to talk to your database via PHP. It is absolutely possible but will take some researching.
