PHP - Building A Quiz

Hello.
I try to write a simple multiple choice quiz. I have my questions and answers in a xml file and I read the file into an array. My main problems is how I'll connect the various sessions where the different questions appear in order to keep the score and sum it up in the end. Also, how do I check if the selected answer is correct or not? Assuming that the correct answers are in an array in php code, can I use javascript to check the answers?
Any help?
Thanks.

Hi All,

I have an array like this where the cars are the first level of the array, and the owners are children of that first level:

[Car 1]
           ----[Owner 1]
[Car 2]
           ----[Owner 2]
[Car 2]
           ----[Owner 3]
[Car 2]
           ----[Owner 4]

I want to convert it to:

[Car 1]
           ----[Owner 1]
[Car 2]
           ----[Owner 2]
           ----[Owner 3]
           ----[Owner 4]

So I started making this script:

$cars = array();
foreach($owners as $owner) {
if(!in_array($owner['Car'], $cars)) {
$cars[] = $owner['Car'];
}

echo array_search($owner['Car'], $cars, true);

$cars[array_search($owner['Car'], $cars)]['Owner'][] = $owner['Owner'];
}

The result of this is the same as the beginning result, any ideas what could be causing that?

I was thinking how can I make a script that will build strings incrementing through each letter starting with "a" and ending with "zzzzzz" or what ever ending length I want such as 12.

So if your were to output everything, you could find the words:
"dog"
"spider"
"superman"
"hippo"
etc

What would be the best way to do this, so I don't have to have a loop that is 500 blocks deep to show a word that is 500 letters

example
Quote

a
...
z
aa
ab
ac
...
az
ba
bb
bc
...
...
aaa
aab
aac

     Hey guys, I'm currently trying to make a tutorial website, and I'd like to have a fairly simple blog / news page that I can update with pictures and news stories.  I would also like people to be able to comment on these postings.  I'm pretty new to PHP but i made a simple blog using a php handler and a database table, but I was just wondering is there some 3rd party application I can use to manage my website with like users and articles and such without having to use their website layout? Like, programs such as WordPress and PHP-Fusion, Joomla etc, dont let you use your own html and css pages do they?
     I want to keep my website but have something purely in the background for me to manage the content and maybe like paste some script to my actual pages or whatever.  Im just lost is all I need a little guidance =]  Thanks a bunch.

Hi Guys

I am trying to build a menu sing the code below, I can get the main headings, the problem arises when I try and produce the sub menus.

Can someone please tell me where I am going wrong, or a better way of getting the desired result
Code: [Select]
<?php
 function submenu()
 {
     $submenu_sql=mysql_query("SELECT * FROM `tbl_menu` where `parent_menu_id` = '$menu_row[menu_id]'");
     if(mysql_num_rows($submenu_sql)>0)
     {
         echo('<ul>');
         while
         ($submenu_row=mysql_fetch_assoc($submenu_sql))
         {
             echo('<li><a href="'.$submenu_row['link'].'">'.$submenu_row['menu_display'].'</a></li>');
             }
             echo('</ul>');
             };
             }

$menu_sql=mysql_query("SELECT * FROM `tbl_menu` where `parent_menu_id` = '0'");
if (mysql_num_rows($menu_sql)>0)
{
    echo('<div id="accordian">');
    while ($menu_row=mysql_fetch_assoc($menu_sql))
    {
        echo('<div class="panel_container">
        <h3><a href="'.$menu_row['link'].'">'.$menu_row['menu_display'].'</a></h3>
        <div class="panel_body">');
        submenu();
        echo('</div>
        </div>');
        }
        echo('</div>');
        }
        ?>

I am getting the following error
Notice: Undefined variable: menu_row in /home/sites/j-slink.co.uk/public_html/includes/menu.php on line 4


The desired result is to produce a menu with the following layout
Code: [Select]
<div id="accordion">



<div class="panel_container" id="panel1">
    <h3 id="visible">Home</h3>
    <div id="panel1-body" class="panel_body">
    </div>
</div>

<div class="panel_container" id="panel2">

    <h3>Music</h3>
    <div id="panel2-body" class="panel_body">
        <div>
        <ul>
<li>Calling Card Mixing Tape</li>
</ul>
        </div>
    </div>

</div>

<div class="panel_container" id="panel3">
    <h3>Panel 3</h3>
    <div id="panel3-body" class="panel_body">
        <div>
        This is the contents of this panel.
        </div>
    </div>
</div>

<div class="panel_container" id="panel4">
    <h3>Panel 4</h3>
    <div id="panel4-body" class="panel_body">
        <div>
        This is the contents of this panel.
        </div>
    </div>
</div>

<div class="panel_container" id="panel5">
    <h3>Panel 5</h3>
    <div id="panel5-body" class="panel_body">
        <div>
        This is the contents of this panel.
        </div>
    </div>
</div>

</div>

Thanks in advance

In php how could I build a .net application?
So I have a source that I want to build in .net, but i'm not sure how...

If I use this code:
$values = range(0, 10);
echo "<select name=\"my_field\">\n";
foreach($values as $v) {   
echo "<option value=\"$v\">$v</option>\n";
}echo "</select>\n";

to generate a dropdown, it will offer options from 1 thru 10. 

Is there any way to make them increment by .50 (ie: 0.0, 0.5, 1.0, 1.5, 2.0, 2.5, etc.?

Greetings freaks,

I am trying to figure out how to build an array for the following purpose, and have just been spinning my wheels as it's a very new topic to me.

I have a database with a table and the following important rows:  ID, Parent, and Name.  In this table, Parents are given the value 0 for 'Parent' and a unique 'ID' & 'Name' - children are given all unique 'ID' and 'Name' with the value for Parent being 'ID' of the Parent they belong to.

Example: ( as 'ID', 'Parent', 'Name') 1, 0, John & 2, 1, Jane / 3, 0, Mark & 4, 3, Mary & 5, 3, Mindy.

As you can see, the second names in each example (the children) are connected to their parents by the 'Parent' row, whereas the first names (the parents) are not associated with anybody else.

What I would like to do is build an array that associates every child to the parent ([Parent] => child1 ).  Simple MySQL grants me an array for the parents:

$parent_pull = mysql_query('SELECT * FROM `table` WHERE Parent = 0')
while($row = mysql_fetch_array($parent_pull)){
$name[] = $row['Name'];
$id[] = $row['ID'];
}


Now, I want to be able to use the $id[]s to build arrays WHERE Parent = $id[].

I have tried in loops with $id[$i] & $i++ to cycle the array values, but PHP tells me there mysql_fetch_array() expects parameter 1 to be resource, boolean given ... on line 32.

$i = 0

while($i < 10){
$child_pull = mysql_query('SELECT * FROM `table` WHERE Parent = $id[$i] ');
$child = mysql_fetch_array($child_pull);
$child[] = $child['Name'];  <-- Line 32
$i++;
}


How would I go about pulling all the children and associating them with their parents?

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!

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...

i want online quiz in php mysql

Hello everyone, I have a datatbase containing fields id, question, answer, and type. The questions are in true/false format, multiple choice and fill in the blank(text). At the moment, I am only trying to get the true and false questions to work. My code is as follows

Code: [Select]

<?php

$connection = mysql_connect("localhost","root","root") or die("couldn't connect");
$select = mysql_select_db("login") or die ("cannot select database!");

$query = mysql_query("SELECT * FROM questions");

$numrows = mysql_num_rows($query);

if ($numrows!=0)
{
//code to login
while($row = mysql_fetch_assoc($query))
{
$dbquestion = $row['question'];
$dbanswer = $row['answer'];
$dbtype = $row['type'];
$dbid = $row['id'];
$correctanswer =  explode('|',"$dbanswer");



switch($dbtype){
case "mchoice":
echo"<br/>"; echo $dbquestion; echo"<br/>";
break;

case "boolean":
echo"<br/>"; echo $dbquestion; echo"<br/>";
echo $correctanswer[0];

//display radio buttons

?>
<form name="boolean" method="POST" action="<?php echo $_SERVER['PHP_SELF'] ?>">
True
<input name="question" type="radio" value= "True" />
False
<input name="question" type="radio" value= "False" />
<input name="id" input type="hidden" value="<?php $dbid ?>" />
<input type="submit" name="submit" id="submit" value="Submit" />

<?php
echo "The answer submitted was ";
echo  $_POST['question'];
?>

<?php
break;

case "text":
echo"<br/>"; echo $dbquestion; echo"<br/>";
//display text box
break;
}
}
}
?>

The problem I'm having is that this creates a submit button for each question. When choosing true or false for the answer and pressing submit, the answer is selected for every question. I need the code  to look at what the user has entered, check the answer against correctanswer[0].

I'm really in a bit of a hole here and if anyone can help me it would be greatly appreciated.

Many thanks in advance
James

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; 

?>

Hello every body. Currently I am creating a quiz section but I'm facing some problem.   The thing i want is that the questions which the user has played before should not come again.   So here is my quiz table.

+-------------+-------------------------------------+------+-----+---------+----------------+
| Field       | Type                                | Null | Key | Default | Extra          |
+-------------+-------------------------------------+------+-----+---------+----------------+
| qid         | int(11)                             | NO   | PRI | NULL    | auto_increment |
| questions   | varchar(255)                        | NO   | UNI | NULL    |                |
| correct_ans | varchar(50)                         | NO   |     | NULL    |                |
| option1     | varchar(50)                         | NO   |     | NULL    |                |
| option2     | varchar(50)                         | NO   |     | NULL    |                |
| option3     | varchar(50)                         | NO   |     | NULL    |                |
| category    | enum('Maths','Bollywood','Special') | NO   |     | NULL    |                |
+-------------+-------------------------------------+------+-----+---------+----------------+

Then I have created another tablle where I stored their user id and the questions Iid they have played. Here is the table.

+----------------+---------+------+-----+---------+-------+
| Field          | Type    | Null | Key | Default | Extra |
+----------------+---------+------+-----+---------+-------+
| mid            | int(11) | NO   | PRI | NULL    |       |
| quiz_questions | text    | NO   |     | NULL    |       |
+----------------+---------+------+-----+---------+-------+

In the above table, the ids are stored in this pattern     1,5,10,6,7,11,15,29,2   ------------------> Tis are the quiz id.   I'm using this query but to bring the uinque questions but still the same questions are comming..

$q = $this->database()->prepare("SELECT quiz_questions FROM quiz_played WHERE mid = ?");
        $q->bindParam(1, $mid,PDO::PARAM_INT);
        $q->execute();
        $row = $q->fetch(PDO::FETCH_ASSOC);       
        $q->closeCursor();
        $q1 = $this->database()->prepare("SELECT * FROM quiz WHERE qid NOT IN (?) ORDER BY RAND()");
        $q1->bindParam(1, $genre,PDO::PARAM_STR);
        $q1->bindParam(1, $row['quiz_questions'],  PDO::PARAM_STR);
        $q1->execute();
        return  $q1->fetch(PDO::FETCH_ASSOC);

Any help will be really appreciated.
