checkout_process.php and HTML addition

[carlost]

Hello!

 

Anyone have a clue as to how I can add a small amount of HTML to the checkout_process.php file.

 

I am using ECHO payment processing, and when a credit card payment is not accepted, for whatever reason, the "Transaction Denied" statement is posted through the checkout_process.php file.

 

What happens is the customer is shown the "Transaction Denied" text, and nothing else - leaving them stranded on the page.

 

I simply want to put a table with my logo, and a link back to the checkout_payment.php page - so that the customer can reenter payment info.

 

When I add the HTML, I end up with what I want appearance wise, BUT, with the following warning:

 

"Cannot modify header information - headers already sent by (output started at /home/xxxxx/public_html/checkout_process.php:182) in /home/ xxxxx /public_html/includes/functions/general.php on line 29"

 

This happens when testing using the OSC cc.php payment. When using the ECHO payment module - it will not go through at all, only giving me a ERROR response from ECHO.

 

Any thoughts, input would be much appreciated.

 

Thanks in advance.

There's not an easy answer to this one. As the code is designed, you can't have anything that creates output in checkout_process.php. Any text or HTML will cause an error in the redirect. What you should do is capture the error code that your processor is returning and redirect to an error page. The error page would then have an explanation of the problem and a link back to checkout_payment.php.

Thanks for the response Jim!

 

I haven't a clue as to how I might go about doing as you suggest. If you have any more time, and are so inclined, I would appreciate some details.

I'm sorry that I can't give you more information. I'm not familiar with the ECHO module. Perhaps somebody who is more familiar with this module can help you fix it.

There is a way to get around this. I will try to get the code together and post it here tomorrow. I was dealing with the same thing so I modified the code to redirect back to the payment page and display an error just as if the user had entered an invalid card number or forgot to add cvv code.

Hey Chris!

 

Thanks much for your time, your response.

 

I have implemented the changes - only to discover that ECHO cancelled my test account, apparently because I was using invalid credit card numbers to test.

 

I should get re-activated soon. And I?ll post my success. I can tell already that it's likely working as the response I am getting presently "Verification of your account FAILED. Please go back and reenter your credit card information." is now coming to the payment page (checkout_payment.php).

 

I am testing on a test website as my live site has been up and working for a while now.

 

Meanwhile there are a few other things I am wondering about concerning ECHO. I am assuming that you use them too.

 

Have you been incurring additional surcharges for commercial MC & Visa charges?

 

Do you know about the reduction when a "PO#" and "Sales Tax" field are used?

 

Appreciate any more input from your experience with them.

 

Thanks again.

 

Carlos

Carlos,

 

I'm glad to hear that you got this working. I was pretty proud of myself when I finally got all of that to work. So its nice to hear that someone else will benefit from my work. Maybe I'll put it together as an enhancement package for others.

 

I've only been using ECHO for a short time and have processed about 5 orders. So I'm pretty new with the whole thing myself.

[carlost]

Chris,

 

Works like a charm!

 

Thanks again.

Chris,

 

I am have trouble with the ECHO module. Everytime I run an order the cart redirects to the login page. The contents remain in the cart and according to ECHO no transaction went through. Any ideas on this.

 

Is there a server setting I may be missing?

 

Thank you for your time.
