Changing the amount in SIM Integration

[bprado]

Hi, im new here, and im trying to make SIM Integration with Authorize.net, first excuse my bad english!!!

everything is OK in my test using the sample code (php version), but when i try to change the defaul amount via Web, then i get a error, i read the forum about putting trim in the variable but still i getting the error.

Here i put diferent trim:

if ($_REQUEST["amount"])
    { $amount = trim($_REQUEST["amount"]); }

if( phpversion() >= '5.1.2' )
{    $fingerprint = hash_hmac("md5", $loginID . "^" . $sequence . "^" . $timeStamp . "^" . trim($amount) . "^", $transactionKey); }
else
{ $fingerprint = bin2hex(mhash(MHASH_MD5, $loginID . "^" . $sequence . "^" . $timeStamp . "^" . trim($amount) . "^", $transactionKey)); }

and i always get this msg: (99) This transaction cannot be accepted.

To enter a different amount via web i change the input field from hidden to text, like this:

echo "    <INPUT type='text'   name='x_amount' value='$amount' />";

Could you provide the code for asp users as well?

Authorize.Net has sample code in ASP.

I am using the sample code but don't understand how to update the hidden field x_amount after the user clicks on the Submit button.

You update this:

    $amount = "19.99";

in the parameters area near the top of he sample code.

Hi guys,

I know this is an ancient topic.. when I run Dave's code I get this error:

Parse error: syntax error, unexpected T_VARIABLE in sim.php on line 45

Line 45 contains $LiveLoginId = "xxxxxxxxxxx";      where xxxxxxxxxx is my liveloginID
Line 46: $LiveTransactionKey = "xxxxxxxxxx";

Any idea of what may be going on?  thanks.

There is a semicolon missing at the end of this line:

$ReturnHomePage = "www.someurl.org"

 Just add it there and it should work

$ReturnHomePage = "www.someurl.org";

Gotcha, now it's throwing an error for simlib.php.  What does this file do and where may I acquire it?

Warning: include(simlib.php) [function.include]: failed to open stream: No such file or directory in sim.php on line 81

Warning: include(simlib.php) [function.include]: failed to open stream: No such file or directory in sim.php on line 81

Warning: include() [function.include]: Failed opening 'simlib.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in sim.php on line 81

Thank you for your help.

simlib.php probably represents the path to the SIM library file in your Authorize.net PHP SDK (at least, I would hope so...) Try changing to that and see if it works.

Thank you for your help TJ, looks like I have it sorted out now. You guys are a lifesaver.
