CONFIGURATION:
Go to the function post_echeck and change the $payto and $paytoid variables
to match what you have with ChecksByNet. Alternatively, you could pass these
in from the parent script. If ChecksByNet ever changes their
submission url, you’ll have to change the $url variable.
EXAMPLE:
Note that in a production environment, you wouldn’t want to pass $_REQUEST in
to the post_echeck function as the end user would be able to change the amount,
payto, and paytoid at will. Ideally, you pull the cbn_ variables out of
$_REQUEST, do any regex checks you want to do on your side, and directly
set the amount from the server side.
post_echeck works by returning an array with the keys “approved” and “err”.
$array['approved'] // If set, echeck was approved.
$array['err'] // Human readable text of all errors.
$array['RSPxxxx'] // Server generated error as key, human readable error as value.
Useful for parent scripts that want to do more with the error.
$ec = new echeck;
$result = $ec->post_echeck($_REQUEST);
if ($result[approved])
{ print “Echeck approved
\n”; }
else
{ print “Declined:
\n”;
print $result[err];
}
VARIABLES:
Put all the variables into an array and pass that array to post_echeck.
Prefix all variables in the array with cbn_
Example:
$checkno = 123;
$check['cbn_checknbr'] = $checkno;
$result = $ec->post_echeck($check);
Checksbynet requires the following variables FROM THE CUSTOMER:
Check Number Value: checknbr Needs to be greater than 99 / 6 Max
Customer’s First Name: writerfirst 15 Max (only for personal checks)
Customer’s Last Name: writerlast 29 Max
Customer’s Business Name: writername 50 Max (only for business checks)
Customer’s Address: writeraddr Street address required / 50 Max
City: writercity 30 Max
State: writerst 2 characters required
Zip: writerzip 5 digits required
Bank Name: bankname 50 Max
Bank City: bankcity 30 Max
Bank State: bankst 2 characters required
Bank Zip: bankzip 5 digits required or can be blank
MICR: micr 80 Max
Customer’s Driver’s License: idnbr Do not include dashes or spaces / 40 Max
Driver’s License State: idst 2 characters required
Customer’s Phone Number: phone 10 digits required / 14 max
Customer’s Email: email “@” and “.” required / 50 Max
They also require these variables FROM THE MERCHANT:
Check Dollar Amount Value: checkamt Needs to be greater than $1.00/ 10 Max characters
These variables are required by the MERCHANT, but can be set in the post_echeck
function, and do not need to be passed in from the parent program.:
Pay to: payto Who the check is being made out to. 50 Max
Pay to id: paytoid Merchant id number
