I have thisphp script on one page which takes variables from input fields:

if($fname <> "" and $lname <> "" and $ydept <> "") { if ($percentage >= "85") { mail ($myEmail, $mailSubject, $msgBody, $header); mail ($userEmail, $sentMailSubject, $sentMailBody, $sentHeader); $filename = "blah.txt"; #Must CHMOD to 666, set folder to 777 $text = "\n" . str_pad($fname, 25) . "" . str_pad($lname, 25) . "" . str_pad($empID, 15) . "" . str_pad($doh, 15) . ""; $fp = fopen ($filename, "a"); # a = append to the file. w = write to the file (create new if doesn't exist) if ($fp) { fwrite ($fp, $text); fclose ($fp); #echo ("File written"); } else { #echo ("File was not written"); } header ("Location: yes.php?fname=$fname&type=$type"); } else { header ("Location: didnotpass.php?percent=$percentage&type=$type"); } } else { header ("Location: empty.php?type=$type"); }

And the didnotpass.php script is:

<?php if (isset($_GET['type']) && isset($_GET['percentage'])) { $percent = trim(strip_tags(stripslashes($_GET['percent']))); $type = trim(strip_tags(stripslashes($_GET['type']))); if ($type == "Clinical") { ?> The Certificate of Attendance has been completed yet, but your score of $percent% is less then the passing score of 85%.<br><br> Please <b><a href="C.php">Click Here</a></b> to retake the certification. <?php } else { ?> The Certificate of Attendance has been completed yet, but your score of $percent% is less then the passing score of 85%.<br><br> Please <b><a href="nonC.php">Click Here</a></b> to retake the certification. <?php } } else { ?> Please <b><a href="start.php">Go To Certification Homepage</a></b> to start the certification. <?php } ?>

The issue I am having is whether or not the score is 85% or not, it goes to the last else statement:

Please <b><a href="start.php">Go To Certification Homepage</a></b> to start the certification.

Is my IF statement correct:

if ($percentage >= "85")

I am thinking it is working correctly because it is routing to the correct page but the IF/ELSE statement in the didnotpass.php is not working correctly. Anyone can help me fix it?

I think what is happening is that the query string parameters for percent aren't consistent:

if (isset($_GET['type']) && isset($_GET['percentage'])) { $percent = trim(strip_tags(stripslashes($_GET['percent']))); $type = trim(strip_tags(stripslashes($_GET['type'])));

it should be

if (isset($_GET['type']) && isset($_GET['percent'])) { $percent = trim(strip_tags(stripslashes($_GET['percent']))); $type = trim(strip_tags(stripslashes($_GET['type']))); The if statement refers to $_GET['percentage'] instead of $_GET['percent']
