SIM integration help requested :)

DavidDavid — Wed, 23 Jun 2010 15:50:02 GMT

Hi,

I'm looking for clarification regarding what can and can't be done with SIM. I've modified the following code (thanks stymiee) and everything works how I want it to, except that I would prefer to omit the second step. Is there anyway to just send the "Invoice #" and "Total Due $" directly to Authorize.net? I'm a real novice at PHP, so any help would be appreciated. Thanks!

<HTML>
<HEAD>
    <TITLE> Sample SIM Implementation </TITLE>
</HEAD>
<BODY>
<?php
if (isset($_POST) && is_array($_POST) && count($_POST))
{
    $loginID        = "*********";
    $transactionKey = "****************";
    $testMode       = "false";
    $amount         = (float) trim($_REQUEST["x_amount"]);
    $invoice        = (float) trim($_REQUEST["x_invoice_num"]);
    $sequence       = rand(1, 1000);
    $timeStamp      = time();

    // The following lines generate the SIM fingerprint.  PHP versions 5.1.2 and
    // newer have the necessary hmac function built in.  For older versions, it
    // will try to use the mhash library.
    if( phpversion() >= '5.1.2' )
    {
        $fingerprint = hash_hmac("md5", $loginID . "^" . $sequence . "^" . $timeStamp . "^" . $amount . "^", $transactionKey);
    }
    else
    {
        $fingerprint = bin2hex(mhash(MHASH_MD5, $loginID . "^" . $sequence . "^" . $timeStamp . "^" . $amount . "^", $transactionKey));
    }
?>

INVOICE #: <?php echo $invoice; ?><br />
TOTAL DUE $: <?php echo $amount; ?><br />

Do you mean have the form submit automatically once the Invoice # and amount are submitted? If so you'll need to use JavaScript to do this (keep in mind if somone has JavaScript turned off this won't work):

<HTML>
<HEAD>
    <TITLE> Sample SIM Implementation </TITLE>
</HEAD>
<BODY>
<?php
if (isset($_POST) && is_array($_POST) && count($_POST))
{
    $loginID        = "*********";
    $transactionKey = "****************";
    $testMode       = "false";
    $amount         = (float) trim($_REQUEST["x_amount"]);
    $invoice        = (float) trim($_REQUEST["x_invoice_num"]);
    $sequence       = rand(1, 1000);
    $timeStamp      = time();

    // The following lines generate the SIM fingerprint.  PHP versions 5.1.2 and
    // newer have the necessary hmac function built in.  For older versions, it
    // will try to use the mhash library.
    if( phpversion() >= '5.1.2' )
    {
        $fingerprint = hash_hmac("md5", $loginID . "^" . $sequence . "^" . $timeStamp . "^" . $amount . "^", $transactionKey);
    }
    else
    {
        $fingerprint = bin2hex(mhash(MHASH_MD5, $loginID . "^" . $sequence . "^" . $timeStamp . "^" . $amount . "^", $transactionKey));
    }
?>

INVOICE #: <?php echo $invoice; ?><br />
TOTAL DUE $: <?php echo $amount; ?><br />

    <FORM method='post' action='https://secure.authorize.net/gateway/transact.dll' id="paymentform">
        <INPUT type='hidden' name='x_login' value='<?php echo $loginID; ?>' />
        <INPUT type='hidden' name='x_amount' value='<?php echo $amount; ?>' />
		<INPUT type='hidden' name='x_invoice_num' value='<?php echo $invoice; ?>' />
        <INPUT type='hidden' name='x_fp_sequence' value='<?php echo $sequence; ?>' />
        <INPUT type='hidden' name='x_fp_timestamp' value='<?php echo $timeStamp; ?>' />

That's just what I needed! Thanks for your time and help!

I'm not too worried about the Javascript-thing :)

Hi John,

Thanks for this great code !

however, i'm trying to pass "description" as well, but for some reason it doesn't recognize it and take the value "0".

Could you help me with this matter (posted my code below) ?

<HTML>

<BODY>
<?php
if (isset($_POST) && is_array($_POST) && count($_POST))
{
    $loginID        = "**********";
    $transactionKey = "**************";
    $testMode       = "false";
    $amount         = (float) trim($_REQUEST["x_amount"]);
    $invoice        = (float) trim($_REQUEST["x_invoice_num"]);
    $description    = (float) trim($_REQUEST["x_description"]);
    $sequence       = rand(1, 1000);
    $timeStamp      = time();

    // The following lines generate the SIM fingerprint.  PHP versions 5.1.2 and
    // newer have the necessary hmac function built in.  For older versions, it
    // will try to use the mhash library.
    if( phpversion() >= '5.1.2' )
    {
        $fingerprint = hash_hmac("md5", $loginID . "^" . $sequence . "^" . $timeStamp . "^" . $amount . "^", $transactionKey);
    }
    else
    {
        $fingerprint = bin2hex(mhash(MHASH_MD5, $loginID . "^" . $sequence . "^" . $timeStamp . "^" . $amount . "^", $transactionKey));
    }
?>

INVOICE #: <?php echo $invoice; ?><br />
TOTAL DUE $: <?php echo $amount; ?><br />
DESCRIPTION: <?php echo $description; ?><br />

    <FORM method='post' action='https://secure.authorize.net/gateway/transact.dll' id="paymentform">
        <INPUT type='hidden' name='x_login' value='<?php echo $loginID; ?>' />
        <INPUT type='hidden' name='x_amount' value='<?php echo $amount; ?>' />
		<INPUT type='hidden' name='x_invoice_num' value='<?php echo $invoice; ?>' />
        <INPUT type='hidden' name='x_description' value='<?php echo $description; ?>' />
        <INPUT type='hidden' name='x_fp_sequence' value='<?php echo $sequence; ?>' />
        <INPUT type='hidden' name='x_fp_timestamp' value='<?php echo $timeStamp; ?>' />
        <INPUT type='hidden' name='x_fp_hash' value='<?php echo $fingerprint; ?>' />
        <INPUT type='hidden' name='x_test_request' value='<?php echo $testMode; ?>' />
        <INPUT type='hidden' name='x_show_form' value='PAYMENT_FORM' />
        <input type='submit' value='Submit' />
    </FORM>
    <script type="text/javascript">
        document.getElementById('paymentform').submit();
    </script>
    
<?php
}
else
{
?>

<style>
ul{
	list-style-type: none;
}
</style>

    <FORM method='post' action='<?php echo $_SERVER['PHP_SELF']; ?>'>
	    <ul > 
	    <li><label for="DESCRIPTION" Style="display:block;float:left;width:150px;">DESCRIPTION :</label> <INPUT type='text' name='x_description' value='' /></li><br />
        <li><label for="DESCRIPTION" Style="display:block;float:left;width:150px;">INVOICE #:</label> <INPUT type='text' name='x_invoice_num' value='' /></li><br />
		<li><label for="DESCRIPTION" Style="display:block;float:left;width:150px;">TOTAL DUE $:</label> <INPUT type='text' name='x_amount' value='' /></li><br />

        <input type='submit' value='Submit' />
        </ul > 
    </FORM>
<?php
}
?>

</BODY>
</HTML>

and also, what i would do is have the possibility to pass the value through drop down menus, and when i change for instance :

<li><label for="DESCRIPTION" Style="display:block;float:left;width:150px;">INVOICE #:</label> <INPUT type='text' name='x_invoice_num' value='' /></li> to

<li><label for="DESCRIPTION" Style="display:block;float:left;width:150px;">INVOICE #:</label> <select>
<option name='x_invoice_num' value="1">1</option>
<option name='x_invoice_num' value="2">2</option>
<option name='x_invoice_num' value="3">3</option>
<option name='x_invoice_num' value="4">4</option>
</select>
</li>

it doesn't work anymore.

Your help would be greatly appreciated.

Thanks

Isabelle

Change:

$description    = (float) trim($_REQUEST["x_description"]);

to:

$description    = trim($_REQUEST["x_description"]);

The (float) turns whatever you submit to a number.

As for your dropdown you forgot to name the <select> tag.

Change:

<select>

to:

<select name="description">
