You mean the LinkId to blank, like this?

<form name="PrePage" method = "post" action = "https://scotest.authorize.net/payment/CatalogPayment.aspx"> <input type = "hidden" name= "LinkId" value ="" /> <input type = "image" src="//testcontent.authorize.net/images/buy-now-gray.gif" /> </form>

Or do you mean SIM? If SIM, which fields?

Thanks for the reply.

Actually i have created a simple checkout form, after transaction page go to provided relay url where i get all the values and do DB and Application logic. But at Checkout form if i click on submit, it goes to relay_url with empty values. I want to validate these fields. One more thing, if its not doing validation for me, i have to validate all the fields may be on relay_url page, in this case how i go back to the checkout form, if user done an invalid move, (put empty to required field). And then how can i validate creadit card?

So you are using SIM with relay response?

But at Checkout form if i click on submit, it goes to relay_url with empty values.

So on your checkout form, you click submit and it go straight to the relay URL page and not the authorize.net CC info input page?

I want to validate these fields. One more thing, if its not doing validation for me, i have to validate all the fields may be on relay_url page, in this case how i go back to the checkout form, if user done an invalid move, (put empty to required field).

Again, can you tell us which fields???

And then how can i validate credit card?

What kind of validation do you want to do? authorize.net will return error if the credit card info is not valid.

Yes.

Yes it goes straight to the relay URL page. Even when the credit card, expire date, Address and all the required fields are empty.

Again, can you tell us which fields???

I want to validate, Credit Card - Expire Date - Address - City (these all are required fields)

What kind of validation do you want to do? authorize.net will return error if the credit card info is not valid.

yes if the card info is invalid, or one of the required field is empty.

Yes it goes straight to the relay URL page. Even when the credit card, expire date, Address and all the required fields are empty.

Are you sure You are not using DPM, can you tell me the URL where you put in the CC# and expire date. Did it said https://???.authorize.net/gateway/transact.dll? Because on SIM without the CC# and expire date it show

Credit card number is required.
Expiration date is required.

If you are doing DPM, you can test it with javascript before the submit to authorize.net transact.dll.

Or if are using asp.net without master page, use the <asp:???Validator />

And yes for DPM, it will go directly to the relay response. You will need to test the response to either go back to the checkout page or to the receipt page. Use this https://developer.authorize.net/tools/paramdump/index.php as the relay_response page to see the all the response values.

Updated:

Just run a DPM test without CC# and expiration date

The x_response_code is 3, x_response_reason_code is 33, the x_response_reason_text is "Credit card number is required."

Re: Simple Checkout Validation

haseebkhilji — Wed, 11 Apr 2012 20:46:56 GMT

You are right.

[x_response_code] => 3 [x_response_reason_code] => 33 [x_response_reason_text] => Credit card number is required.

this is what i received.

the url is https://secure.authorize.net/gateway/transact.dll

Then you are using DPM. Validate the inputs with javascript before submitting.

stymiee have some nice javascript credit card info validation here.

haseebkhilji — Wed, 11 Apr 2012 21:11:13 GMT

URL not working!

Re: Simple Checkout Validation

haseebkhilji — Wed, 11 Apr 2012 21:21:56 GMT

I am using PHP.
Basically my site is about buying credits for the site.
I am in test mode, i put all the required values like amount, description of the package and tax, in hidden post values. After the transaction, i got all the values from $_post array in relay_url, and then i set my business logic and display a thank you page (back to my site).

Everything is complete except the form validation that is appearing at https://secure.authorize.net/gateway/transact.dll

What if the javascript disabled by the user? How can i let authorize.net do validation for me. I am worried about disabled javascript and credit card security flaw by using kind of third party validation. Please help!

The URL is http://community.developer.authorize.net/t5/The-Authorize-Net-Developer-Blog/Handling-Online-Payments-Part-3-Data-Validation/ba-p/10006

For SIM you won't be able to do any validation because the page is on Authorize.net. All you can is set the field if it is required in the merchant account setting.

And you said you are running in TEST mode with a production account. A lot of thing do not work with TEST mode.

Get a test account and test it with live mode

I saw the code regarding CC# validation. This is like syntax validation, what if the card No. still unvalid or Out of money or expired?

Re: Simple Checkout Validation

haseebkhilji — Thu, 12 Apr 2012 10:51:20 GMT

Also please suggest me,

I just want that user from my website buy credits that will use in the site, simple checkout seems, you can create form within your website page. But the problem was, i am using codeigniter, and was unable to integrate it with my CI application. Thats why i choose current (DPM) method. Now i understand that, i need to handle validation by myself. I have still no idea about how i can make validation for creadit card (Payment and expired - Not syntax error). Do i need to put validation code in my relay_url page?

That was because I assume you use DPM. You can NOT do any SIM validation on Authorize.net CC info page.

Authorize.net will do simple validation like the length on the CC#, Luhn Formula for check digit, if the expiratedate enter is expirate, required fields are enter, etc. Then authorize.net send the info to your processor for process, only your processor will return if the CC is valid and if it have enough credit.

On your relay response page, you will need to check for the response code "1" to make sure it charge the CC#.

haseebkhilji — Thu, 12 Apr 2012 14:59:18 GMT

Alright! i understood.

1. Now what should i do in order to validate all the fields and CC# right on the payment page?

2. As now you understand my application logic, can you suggest me METHOD for my requirements? (I don't have an ssl)

You can NOT do any validation with SIM payment page.

2. As now you understand my application logic, can you suggest me METHOD for my requirements? (I don't have an ssl)

For SIM, check the result on your relay response page.
