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!

$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);

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):

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">
