How do I send specific information to the payment page?

Hey Ray,
If I want to send specific information like the "Red Star Life Member" card number to the payment page. How do I do that? I see on the confirm.php page that "Name", "Address", etc. can be sent and it shows up on my payment page. My boss would like to check if the person who checks the box is a Red Star life member or not. I have put a space on the checkout.php page for the life member card number. So, if I can do that, I'll be golden. Thanks again for your help in tweaking our store! Have a nice day, eh?
All the best,

If you add the form field to your existing checkout form, then it should be automatically stored and available just like any other field.

Hey Ray,
The Red Star Life Member card number field does not show up when the information is sent to the Authorize.net portal. Thanks for your help.
All the best,

You would have to add it to the name or another field in the authorize.net code.

Ray,
I have placed the following code on the confirm.php page:

<input type="hidden" name="x_life_number" id="x_life_number" value="<?php echo((isset($_POST["life_number"]))?$_POST["life_number"]:"") ?>"
/>

That is where the code is to be placed, correct? It says hidden, so I'm assuming that it gets sent directly to the e-mail (supremehqmoc@lotcs.org) that's listed on the page and doesn't show up on the payment form page. If this information goes directly to that e-mail, then that's awesome! That way my boss can check if the end user is actually a life member or not. Also, is the payment form page generated from e_cart or is it actually the Authorize.net payment form page? I went into our Authorize.net account and checked to see if there is a way to add the life member number there on the virtual terminal. There is not. It seems to be hardwired for just specific blocks of information. Thanks in advance for your help and patience!
Have a nice day, eh?
All the best,

No... there are only specific fields that authorize.net will recognize and use. You would have to update one of those fields and add the value.

Maybe the x_description (it seems like you have that one twice, you should delete the repeated field)

or maybe the x_cust_id would work.

Hey Ray,
I used "cust_id" as my field to insert the Red Star Life Member number. Then I went to the confirm.php page and was wondering why the number wasn't showing up on the checkout page. I noticed that I had to add the "POST" information to the back end of "cust_id". Now it works just fine and the customer ID is there for the Red Star Life Member number. Thanks for your help once again Brother! Have a nice day, eh?
All the best,
Dale
