PHP - Php Online Quiz Application

can anyone please tell me how can I make a quiz in php which displays random questions one at a time

Hey guys, I'm making php quiz, but got some problems with results getting - they are all wrong. Here is the db table for it.

CREATE TABLE IF NOT EXISTS `quiz` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `question` text COLLATE utf8_unicode_ci NOT NULL,
  `answer1` text COLLATE utf8_unicode_ci NOT NULL,
  `answer2` text COLLATE utf8_unicode_ci NOT NULL,
  `answer3` text COLLATE utf8_unicode_ci NOT NULL,
  `correctanswer` text COLLATE utf8_unicode_ci NOT NULL,
  PRIMARY KEY (`id`),
  KEY `pollid` (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=34 ;

And script itself.

$questionNumber = 1;
$query = sql_query("SELECT * FROM quiz ORDER BY RAND() LIMIT $limit");
while ($result = mysqli_fetch_array($query)) { ?>
	<div class="padding">
	 <p>
	 <?php echo "<b><h4>" . $questionNumber . ") " . $result['question'] . "</h4><br></b>"; ?>
	 <input type="radio" name="answer[<?php echo $result['id'] ?>]" value=""> <?php echo $result['answer1']; ?> <br>
	 <input type="radio" name="answer[<?php echo $result['id'] ?>]" value=""> <?php echo $result['answer2']; ?> <br>
	 <input type="radio" name="answer[<?php echo $result['id'] ?>]" value=""> <?php echo $result['answer3']; ?> <br>
	 </p>
	 <hr>
	 </div>

<?php
$questionNumber +=1;
}
    $correctAnswers = 0;
    $wrongAnswers = 0;
    $questions = '';
    
    $idList = join (',', array_map('intval', array_keys($_POST['answer'])));
    $sql = "SELECT id, question, answer1, answer2, answer3, correctanswer FROM quiz WHERE id IN ($idList)";
    $res = sql_query($sql) ;
    $qno = 1;
    while (list($id, $q, $a, $b, $c, $correct) = mysqli_fetch_row($res)) {
	    if ($correct == $_POST['answer'][$id]) {
		    $correctAnswers +=1;
	    }
	    else {
		    $wrongAnswers +=1;
	    }
    }
echo $correctAnswer;
echo $wrongAnswers;
?>

Help me guys!

Hey all!

I am new to these forums, but this seems like a really good place for information. I am a beginner in PHP coding, so I don't have that much experience with how to do quite simple tasks. I have a job to fulfill and I have to create a personality quiz, which basically means a user answers about eight questions with three choices and then he will be dubbed as one of six different personalities. I've tired doing this, believe me, but I just don't get it to work. Are there any websites, downloads, or words of advice you guys could give me? And no, I will not be using one of those quiz generators online; it should be made from raw code.

Thank you so much!

There are ten list or bookmarks from Prof. Horner's Bible-Reading System found (http://www.facebook.com/group.php?gid=46416541831) each having set number of books from the Bible. One is to read ten chapters a day, one chapter from each of the bookmarks.

Type in what day you are on and the program will show you on each of the lists as to what chapter you are suppose to be on.

Also want to show statistics that will display how many times the Bible has been read with a break down of all 66 books of the Bible.

Started a git respo http://github.com/Kutakizukari/Prof-Horners-Bible-Reading-System

Bookmark list as follows:

//List 1
$Matthew = 28;
$Mark = 16;
$Luke = 24;
$John = 21;

//List 2
$Genesis = 50;
$Exodus = 40;
$Levitieus = 27;
$Numbers = 36;
$Deuteronomy = 34;

//List 3
$Romans = 16;
$I_Corinthians = 16;
$II_Corinthians = 13;
$Galatians = 6;
$Ephesians = 6;
$Philipians = 4;
$Colossians = 4;
$Hebrews = 13;

//List 4
$I_Thessalonians = 5;
$II_Thessalonians = 3;
$I_Timothy = 6;
$II_Timothy = 4;
$Titus = 3;
$Philemon = 1;
$James = 5;
$I_Peter = 5 ;
$II_Peter = 3 ;
$I_John = 5;
$II_John = 1;
$III_John = 1;
$Jude = 1;
$Revelation = 22;

//List 5
$Job = 42;
$Ecclesiastes = 12;
$Songs_of_Solomon = 8;

//List 6
$Psalms = 150;

//List 7
$Proverbs = 31;

//List 8
$Joshua = 24;
$Judges = 21;
$Ruth = 4;
$I_Samuel = 31;
$II_Samuel = 24;
$I_Kings = 22;
$II_Kings = 25;
$I_Chronicles = 29;
$II_Chronicles = 36;
$Ezra = 10;
$Nehemiah = 13;
$Esther = 10;

//List 9
$Isaiah = 66;
$Jeremiah = 52;
$Lamentations = 5;
$Ezekiel = 48;
$Daniel = 12;
$Hosea = 14;
$Joel = 3;
$Amos = 9;
$Obadiah = 1;
$Jonah = 4;
$Micah = 7;
$Nahum = 3;
$Habakkuk = 3;
$Zephaniah = 3;
$Haggai = 2;
$Zechariah = 14;
$Malachi = 4;

so on day 1 it should readout

Matthew Chapter 1
Genesis Chapter 1
Romans Chapter 1
I Thessalonians Chapter 1
Job Chapter 1
Psalms Chapter 1
Proverbs Chapter 1
Joshua Chapter 1
Isaiah Chapter 1
Acts Chapter 1

on the second day it should all say Chapter two but Matthew reaches day 28 it should move on to Mark Chapter 1 and so on and so on and with each bookmark list.

Hi all,

 Can anyone offer assistance with the following:

 I am trying to obtain a score from a users radio button selection on a simple quiz.

i am not able to obtain the results....

Hey,

I want to start by saying this is the first time I've ever looked at PHP.

I'm using a Wordpress plugin from http://www.netconcepts.com/wordpress-quiz-plugin/

The user answers a few questions, and based off that, they get a  results sheet with their personality type.  The only issue is that none of the line breaks that I've used in the results show up.  It's just one big paragraph (even when in the editing stage, I've made it look all nice).

There's no plugin support for this.

I think it has something to do with this file maybe...

Hey all I have an error in my Facebook application and I'm not sure what's wrong (New to PHP).

The error output is:

Code: [Select]
Warning: array_rand() [function.array-rand]: Second argument has to be between 1 and the number of elements in the array in /home/app/view.php on line 15
And the PHP lines are as follows:

$friends = $facebook->api('/me/friends');
                print_r(array_rand($friends, 3)); 

Hi all, this is my first time on this forum!

I have a background with HTML and CSS but have recently started a Masters in Computer Science hoping to come out of it with the tools to get a job with PHP development.

Our first assignment has somewhat 'thrown me in the deep end' as we have to construct a search engine that indexes the words of a number of documents and rank them using the TF*IDF algorithm along with the log rule associated with Information retrieval.

I am completely new to PHP so the past week has been something of a crash course - This is the code I have so far:
Code: [Select]
<?php 

$filename = 'airlines.txt';
$fp = fopen( $filename, 'r' ); 
    $file_contents = fread( $fp, filesize( $filename ) ); 
    fclose( $fp ); 

//$new_contents = ereg_replace("[^A-Za-z0-9]", "", $file_contents);

/*$file_contents = trim($file_contents); 
    $file_contents = preg_replace('/\h+/', ' ', $file_contents); 
    $file_contents = preg_replace('/\v{3,}/', PHP_EOL.PHP_EOL, $file_contents); */

$pat[0] = "/^\s+/";
$pat[1] = "/\s{2,}/";
$pat[2] = "/\s+\$/";
$rep[0] = "";
$rep[1] = " ";
$rep[2] = "";

$new_contents = preg_replace("/[^A-Za-z0-9\s\s+]/","",$file_contents);
$new_contents = preg_replace($pat,$rep,$new_contents);
//preg_replace('~\s{2,}~', ' ', $text);

$commonWords = array('a','able','about','above'........and another few hundreds cut out of this not to hurt your eyes!);


$lines = explode ( "\n", $new_contents);
$lines2 = implode (" ", $lines);
$words = explode ( " ", $lines2 );

$useful_words = array_diff( $words, $commonWords );

/*for($i = 0; $i < count($lines); $i++) {
echo "Piece $i = $lines[$i] <br />";
}*/

for($i = 0; $i < count($useful_words); $i++) {
echo "Words $i = $useful_words[$i] <br />";
}

  
//$arr=array("blah1","blah2","blah3");
file_put_contents("demo2.txt",implode(" ",$useful_words));

//$file_c = file_get_contents("demo.txt");
//$colms = explode(",",trim($file_c));
//print_r($colms);

//echo $lines[2];
?>
I've got to the stage where that strips out most of the stop words when the final array is printed, but they have been replaced with spaces or something that I have not come acoss because as you may see I had a bit of trouble originally stripping the punctuation marks.

I'm hoping someone can point me in the direction as to how to organise the words I have left after the stripping of stop words which are of no use during the search.  I need to store those words into another array and index them which says how many times they appear in that document.

I've come across the function array array_count_values ( array $input ) on the manual but I'm not sure about the best way to use it.

I've attached the files I've used if that helps.

Any help would be greatly appreciated!

Could anyone help me please. I am trying to create a quiz in (quiz.php) which is works fine, but when I am trying to correct the quiz in another page (result.php) I had an error. I think the problem with posted answers and I couldn't solve it.   This is my code in (quiz.php):

<form method="post" action="result.php">
<?php 
session_start();

$questionNumber = 1;

$query = mysql_query("SELECT * FROM Question WHERE TID = 'TEST' order by RAND()");
while ($result = mysql_fetch_array($query)) { ?>

	 <?php echo $questionNumber . ") " . $result['Question'] . "<br>"; ?>
	 <input type="radio" name="answer<?php echo $result["QID"] ?>" value="A"> <?php echo $result['A']; ?> <br>
	 <input type="radio" name="answer<?php echo $result["QID"] ?>" value="B"> <?php echo $result['B']; ?> <br>
	 <input type="radio" name="answer<?php echo $result["QID"] ?>" value="C"> <?php echo $result['C']; ?> <br>
	 <input type="radio" name="answer<?php echo $result["QID"] ?>" value="D"> <?php echo $result['D']; ?> <br>

<?php
$questionNumber +=1;
}
?>
	  <input type="submit" name="checkQuiz" value="Check Quiz" onclick="location.href='result.php'" />
      
</form>

And This is my code in (result.php):

<?php

if(isset($_POST['checkQuiz'])) {

$correctAnswers = 0;
$wrongAnswers = 0;



$idList = join (',', array_map('intval', array_keys($_POST['answer'])));

 $sql = "SELECT QID, Answers FROM correct WHERE QID IN ($idList)";

while (list($QID, $correct) = mysql_fetch_row($res)) {

if ($correct == $_POST['answer'][$QID]) {
		 $correctAnswers +=1;
}
else {
		 $wrongAnswers +=1;
}
}
}

?>

// in the body

<?php 

$numberOfQs = $correctAnswers + $wrongAnswers;
$score = round(($correctAnswers / $numberOfQs) * 100);
?>

Correct Answers: <?php echo $correctAnswers; ?> <br>
Wrong Answers: <?php echo $wrongAnswers; ?> <br>
Sco  <?php echo $score; 

?>

Hi people.
I'm building a quiz with one correct answer out of possible 4.
My problem is that after I choose a random answer (which is the correct one) I have problems with choosing random 3 wrong answers which are not the same as answer 1 (they all come from the same table).

My first mysql query gives me back 1 row
my second mysql query gives me back 15 row (there were 16 - 1 which is the correct one).
How can take only 3 rows out of that second query and output them into variables that I can later echo into a form?

Can you help me understand this problem or can you propose an alternative method to deal with this?

Here are my two queries:
Code: [Select]
// Fetch random answer (correct)
 $query = "SELECT * FROM psychofarm_brand WHERE `id`=".$randomNumber;
    $result = mysql_query($query);
    $row = mysql_fetch_array($result);

// Fetch wrong answer

    $query2 = "SELECT * FROM psychofarm_gen WHERE `id`!=".$randomNumber;
    $result2 = mysql_query($query2);
    $row2 = mysql_fetch_array($result2);


I hope this is clear.
Thanks

I am building program to manage payment/monthly payments. I've ran into an issue that I haven't been able to overcome and need some help. I've been lurking for a while and decided it was time to ask you guys...Here's the issue:

I have a table 'payments' that contains scheduled payments that looks like:

id clientid paymentduedate balance expected pending 367 112233 4/16/2011
1030.00 257.50
Y
368 112233 5/16/2011
1030.00 257.50
Y
369 112233 6/16/2011
1030.00 257.50
Y
370 112233 7/16/2011
1030.00 257.50
Y


What I need to do that I haven't figured out is to adjust the expected amount according to the payment, update the status to N (not pending) without affecting the later expected payments.

For example:
they make a payment of $257.50, applies that to row 367, sets the status to N, but leaves the other status' to Y (for obvious reasons). the make a payment of $250.00, leaving the balance at $7.50, so lets add $7.50 to row 368, mark 367 status to N the make a payment of $300.00, leaving the expected balance at $0.00 for row 367, but adjust the balance for row 368 to $215.00
Any ideas?

Thanks
