Help with if/else statements

zoobie

I've just about finished this short script but a few of my if/else statements need help. Could someone take a look? They're in bold near the bottom. Thanks a mil.

<?php

$my_email = 'my-primary-email@home.com';

// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';

foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}

// post back to PayPal system to validate
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('www.paypal.com', 80, $errno, $errstr, 30);

// assign posted variables to local variables
$item_name = $POST['item_name'];
$item_number = $POST['item_number'];
$payment_status = $POST['payment_status'];
$payment_gross = $POST['payment_gross'];
$txn_id = $POST['txn_id'];
$receiver_email = $POST['receiver_email'];

if (!$fp) {
echo "<html><body bgcolor='#ffffff'><br><br><div align='center'>SERVER ERROR - Try again later</div></body></html>";
}

else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {
if (strcmp($receiver_email,$my_email) == 0) {
echo "ERROR 904 - Receiver email mismatch";
}

if (strcmp('Completed',$payment_status) == 0) {
     echo "ERROR 707 - Payment not completed";

}

if (strcmp('0.03',$payment_gross) == 0) {
echo "ERROR 803 - Price has been changed";
}

//if everything has passed, go ahead and show the echo below

 else
    echo "<html><body style='background-color:black;overflow:auto'><br><br><div align='center'><form name='fred' action='mail.php' method='post'><button style='border:1px solid white;width:200px;height:35px;background-color:black;font:bold 20px tahoma;color:lime;cursor:pointer' onclick='this.fred.submit();'>SEND IT!</button></form></div></body></html>";
}

  else if (strcmp ($res, "INVALID") == 0) {
  echo "ERROR 007 - There is something wrong with your Paypal account.<br>Payment denied, failed, pending, or unconfirmed.";
  }

}[/b]
fclose ($fp);
}
?>

it's quite good to use the [ php ] tags around your code, easier to read. You can always use comments // to mark the beginning and the end of the problem code.

So, what were the errors you were experiencing? In what way do the if's not work?

Not too sure on what exactly you are asking but if I were to guess, I think the best way to handle this is to use nested if statements.

i.e:

if (strcmp($receiver_email,$my_email) == 0)
{
echo "ERROR 904 - Receiver email mismatch";
i f (strcmp('Completed',$payment_status) == 0)
{
echo "ERROR 707 - Payment not completed";
if (strcmp('0.03',$payment_gross) == 0)
{
echo "ERROR 803 - Price has been changed";
if (strcmp ($res, "INVALID") == 0)
{
echo "ERROR 007 - There is something wrong with your Paypal account.<br>Payment denied, failed, pending, or unconfirmed.";
}
}
}
}

//if everything has passed, go ahead and show the echo below
else
{
echo "<html><body style='background- color:black;overflow:auto'><br><br><div align='center'><form name='fred' action='mail.php' method='post'><button style='border:1px solid white;width:200px;height:35px;background-color:black;font:bold 20px tahoma;color:lime;cursor:pointer' onclick='this.fred.submit();'>SEND IT!</button></form></div></body></html>";
}

Thanks...I'll give it a shot...but when I test, all I get after payment is another Paypal page and not my dynamically-created echoed page in the code...
