I am temporarily including some extra "testing" code within my program to help me troubleshoot it. It won't be in the final program. I'm trying to compare the correct answer in a quiz program ($ans) with the user's answer ($_POST['guess']). Even when the user picks the right answer, the program still spits out, "wrong!" I am not seeing my logical error here, but I obviously have one. I attached a screen shot of the output. I hope it helps. Thank you all.
if (isset($_POST['qid'])){ //qid is the question id
$_SESSION['qid']=$_POST['qid'];
print_r($_SESSION);
$ans = $db->query("SELECT answer FROM QuestionsAnswers WHERE questionid = " . $_SESSION['qid']);
echo "<br />";
print_r ($ans); //correct answer
while($row = $ans->fetch(PDO::FETCH_ASSOC)) {
echo "<p>Here is my Thursday 6pm attempt:xxx" . intval($row['answer']) . "xxx</p>";
echo "<p>User guessed:xxx" . intval($_POST['guess']) . "xxx</p>";
echo '<p>the extra exes ("xxx") are to demonstrate there are no spaces in the field data.</p>';
}
if (intval($row['answer']) == intval($_POST['guess'])){ //values converted to integers just in case one or both is/are a string
echo "<p>Right!</p>";}
else{
echo "<p>wrong!</p>";
}
It is bugging me that PHPFreaks won't let me log into my regular account. Cool. At least I can log in using Facebook. Different account, same person. It is still me. Thanks to all for any help with this one.
(please see attached output.)
