Improve This?

**ThaRubby** · Jun 11th, 2005, 08:21 PM

Ok this code is working decent but needs to be improved. I tried to make it so the user cant know what his score means until he tells me it, hence the multiplying, but ill make that better later. The problem is when a user hits one answer that he knows is correct it will give him a score like 105, when he knows another one and grades it it gives him a 110. So now he sees a pattern counts the questions and wala. Can someone make it so it only grades it once? Sorry this is my first time using PHP.

do you mean... you want to make sure all the answers are filled before the user's quiz is graded? could you give a link to the "almost finished" page?

**ThaRubby** · Jun 11th, 2005, 08:35 PM

I only want the user to be able to click submit one time, to prevent him from figuring out the answer's pattern. http://cyber-knowledge.net/~rub3x/quiz.php

per session? or ever?

**ThaRubby** · Jun 11th, 2005, 08:39 PM

What do you consider a session? Like deleting the cookies? I would like it to go by IP address.

**ALL** · Jun 11th, 2005, 09:15 PM

try this:

PHP Code:


<?php

$ips = file("ips.txt");

foreach ($ips as $ipaddies){

  if($ipaddies == $_SERVER["REMOTE_ADDR"]){

   exit("You have already taken this quiz!");

  }

}



$handle = fopen("ips.txt", 'a+');

  fwrite($handle, implode("\n", $ips) . "\n" . $_SERVER["REMOTE_ADDR"]);

fclose($handle);



$answers = array("b","c","d","a","b","c","a","d","c","b","c","b");

for ($i=1; $i<=12; $i++){

  if($_POST["answer$i"] == $answers["$i"]){

    $y++;

  }else{

    $xprint .= "#$i is $answers[$i]\n";

  }

}



$y = ($y + 20) * 5;

if ($y == "100") { $y = ""; }

  echo $y "\nAnswers you missed, and their corrections:\n$xprint";

}

**ThaRubby** · Jun 11th, 2005, 10:08 PM

That doesnt work. When the user loads the page, it logs the ip, therefor when they hit the button it says already toke the test.

**ALL** · Jun 11th, 2005, 10:25 PM

oh, simple fix...

PHP Code:


<?php 

if($_POST['submit']){

  $ips = file("ips.txt"); 

  foreach ($ips as $ipaddies){ 

    if($ipaddies == $_SERVER["REMOTE_ADDR"]){ 

     exit("You have already taken this quiz!"); 

    } 

  } 



  $handle = fopen("ips.txt", 'a+'); 

    fwrite($handle, implode("\n", $ips) . "\n" . $_SERVER["REMOTE_ADDR"]); 

  fclose($handle); 



  $answers = array("b","c","d","a","b","c","a","d","c","b","c","b"); 

  for ($i=1; $i<=12; $i++){ 

    if($_POST["answer$i"] == $answers["$i"]){

well, i cant test it, because my laptop (with php, cgi, exc...) and i are parted for the time being.

anyway, the (best) thing to do is to have a file on the server with all the questions/answers in it.

here is what i got on it before quitting (going to bed):

PHP Code:


<?php 

if($_POST['submit']){ 

  $ips = file("ips.txt"); 

  foreach ($ips as $ipaddies){ 

    if($ipaddies == $_SERVER["REMOTE_ADDR"]){ 

     exit("You have already taken this quiz!"); 

    } 

  } 



  $handle = fopen("ips.txt", 'a+'); 

    fwrite($handle, implode("\n", $ips) . "\n" . $_SERVER["REMOTE_ADDR"]); 

  fclose($handle); 

  

  $qafile = file("questions.txt");

  foreach($qafile as $num => $qs){

    $qanda = split(chr(1), $qs);

    if($_POST["q$num"] == $qanda[1]){

      $y++;

    }else{

      $xprint .= "Numer $num, <i>$qanda[0]</i>'s should have been $qanda[1], $qanda[2]<br />\n";

    }

  }



  $y = ($y + 20) * 5; 

  if ($y == "100") {

    $y = "";

  } 

  echo "Your score is: <i>$y</i>\n$xprint";

} 

?>

well, i didnt finish this, and probably wont, but i'll give you what i got, while working on it:

PHP Code:


<html>

<head>

<title>Add/Delete Questions</title>

</head>

<body>

<form method="POST" action="edit.php">

    <table border="0" width="100%">

        <td>

<?php

if($_POST['B1']){

  $qandafile = file("questions.txt"); 

  foreach ($qandafile as $num => $qsandas){ 

    if($_POST["c$num"]){

      $qandafile["$num"] = '';

    }

  }

  foreach ($qandafile as $num => $tmp){

    if ($qandafile[$num] == ''){ array_splice($qandafile, $num); }

  }

  $handle = fopen("questions.txt", 'a+'); 

    fwrite($handle, implode("\n", $qandafile)); 

  fclose($handle); 

}elseif($_POST['B2']){

  $qandafile = file("questions.txt");

  $handle = fopen("questions.txt", 'a+'); 

    fwrite($handle, implode("\n", $qandafile) . $_POST['T1'] . chr(1) . ); 

  fclose($handle);

}



$qandafile = file("questions.txt"); 

foreach ($qandafile as $num => $qsandas){ 

  $qanda = split(chr(1), $qsandas);

  echo "<td>$qanda<input type=\"checkbox\" name=\"c$num\"></td><tr>";

} 





?>

<input type="checkbox" name="C1"></td><tr>

    </table>

    <p><input type="submit" value="Delete" name="B1"></p>

    <p>Question:<input type="text" name="T1" size="60"></p>

    <p>Correct Answer: <input type="text" name="T2" size="53"></p>

    <p>False answers (per line):<textarea rows="5" name="S1" cols="36"></textarea></p>

    <p><input type="submit" value="ADD" name="B2"></p>

</form>

</body>

</html>

one thing i really screwed up on was in the questions.txt file, i forgot to put fake answers in, so you will need to find a way to fix that in both php files, if you want to use it like this!
