http://www.elanman.co.uk/2009/03/make-your-own-php-quiz-part-1/

This was the tutorial I was using, with all the code. Even his example that is pretty much identical to mine just works.

I think I actually see where the problem is that you are running into. In step 4 of the tutorial it shows code for if they are registered or not and then starts the session:

if (isset($_POST['register'])) { // they want to register
    $username = trim(strip_tags(stripslashes($_POST['username'])));
    if (ini_get('magic_quotes_gpc')) {
        $username = stripslashes($username);
    }
} else { //they don't want to register
    $random = rand(1,1000);
    $username = 'Anon'. $random;
} //end of if/else conditional</strong>
$num = 0;

If you notice, there is a $num = 0; just after that section. Check to see if that is in your code. That makes a big difference.

I think I may see the problem. Or at least A problem:

foreach ($leaders as $key => $percent) { //---changed $score to percent

	// Check that $counter is less than $limit.
	if ($counter <= $limit) {
		if ($key == $_SESSION['user']) {
			$output .= "<li><strong>$key:</strong> $percent%</li>\n"; //--changed $value to $percent
		} else {
			$output .= "<li>$key: $percent%</li>\n"; //--- again $value to $percent
		}

		if ($group) {
			// Use the modulus operator(%) to create new sub-list.
			if($counter % $group == 0) {
				$output .= "</ul>\n<ul class=\"leaders\">\n";
			}
		}
	}

	$counter++;
}

You should have left most of this alone. It should read something like:

foreach ($leaders as $key => $value) {
       
        if ($counter <= $limit) {
            if ($key == $_SESSION['user']) {
                $output .= "<li><strong>$key:</strong> $value \%</li>\n";
            } else {
                $output .= "<li>$key: $value \%</li>\n";
            }
       
            if ($group) {
                // Use the modulus operator(%) to create new sub-list.
                if($counter % $group == 0) {
                    $output .= "</ul>\n<ul class=\"leaders\">\n";
                }
            }
        }
    
    	$counter++;
    }

Because it is calling forth an array:

$leaders = array();

You have already changed the score variable to percent.

foreach($xml->user as $user) {
	$name = (string)$user->name;
	$percent = (string)$user->score; //---Changed $score to percent
	$leaders[$name] = $percent; //---again $score to percent
}

But, the big question here is: Where are you getting this variable

$percent = (string)$user->score; //<--- this $user->score here

We find where that is being set and we can find what is going on with your percentages.

Find the code that is setting that variable.

Any idea mage?

I think you finally lost me. Just looking at the code you provided doesn't tell me anything about what you changed. Maybe if you put comments in on what you changed I could see the problem easier. Maybe that or my weekend has taken a bigger toll on me then I thought.

Put comments in where you made the changes and try and show the original underneath and we will see where the problem is.

March 16, 2010

Did you copy the code EXACTLY? if so, that comment is idiotically incorrect, and therefore I would not trust this tutorial as far as I can throw it.

Actually, that comment was my fault. It had nothing to do with what was originally posted, it was me mistaking my words. As mjdamato pointed out, I was looking at the problem the wrong way and got myself confused. Ignore the comments that where put in the code.

Oh, and thanks for calling me an idiot! It helps remind me that I'm human, lol.

March 16, 2010

I am making this quiz following a tutorial I got online. it works by having the correct answer as the first part of the array then has a code to shuffle them other wise every time the correct answer will be the first one you can select. I have applied the code and done everything as it says but it isnt shuffling. Every time the correct answer appears first.

Here is the questions and answers array and the code to shuffle it. Can any one give me a hand and help me get it to work?

I think your problem is in the answers array.

<?php 
$questions = array('FTP','AJAX','RSS','XSS','PHP','W3C','XML','YUI','HTML','CGI','SSL','SQL','HTTP','CSS','SOAP','WAI','SSI','JSON','XSLT','WCAG'); 
$answers = array( 
array(0 =>'File Transfer Protocol','Force Through Privately','File Through Protocol','File Test Protocol'),  // <--- This belongs to array "0"
array(0 => 'Asynchronous JavaScript and XML','All JavaScript and XML','Alternative Java and XML','Actual JavaScript and XML'),  // <--- This belongs to array "1"
array(0 => 'Really Simple Syndication','Really Simple Scripting','Ready-Styled Scripting','Really Stupid Syndication'),  // <--- This belongs to array "2", etc.

?>

Change the zeros to correspond with the question array number.

Try that, see if it helps.

March 16, 2010

I have this code

<?php $country=$_POST['country'];
if($country[0]=="brazil"){
$brazil="CHECKED";}

if($country[1]=="paraguay"){
$paraguay="CHECKED";}

if($country[2]=="germany"){
$germany="CHECKED";}

if($country[3]=="argentina"){
$brazil="CHECKED";}

if($country[4]=="japan"){
$brazil="CHECKED";}

?>
<html>
<head>
</head>
<body>
<form name=form1 action=$_SERVER['PHP_SELF'] method=POST>
<input type =checkbox name=country[] value=brazil <?php echo $brazil;?>>Brazil
<input type =checkbox name=country[] value=paraguay <?php echo $paraguay;?>>Paraguay
<input type =checkbox name=country[] value=germany <?php echo $germany;?>>Germany
<input type =checkbox name=country[] value=argentina <?php echo $argentina;?>>Argentina
<input type =checkbox name=country[] value=japan <?php echo $japan;?>>Japan
<input type=submit value=okay>
</form>
</body>
</html>

The problem is when i tick on all checkboxes and click on the submit button, i only found that only 3 checkboxes being ticked although i have ticked 4 checkboxes...??Which code is wrong??

thanks

my guess would be these lines here:

if($country[0]=="brazil"){
$brazil="CHECKED";}

if($country[1]=="paraguay"){
$paraguay="CHECKED";}

if($country[2]=="germany"){
$germany="CHECKED";}

if($country[3]=="argentina"){
$brazil="CHECKED";}  // <--- Here

if($country[4]=="japan"){
$brazil="CHECKED";}  // <--- Here

you have $brazil being checked 3 times, so it only reads 3 checks, not 4 or 5.

Found a neat little JS function that helps with onloads:

<script type="javascript">
    function addLoadEvent(func) {
        var oldonload = widow.onload;
        if (typeof window.onload != 'function'){
            window.onload = func;
        }else{
            window.onload = function(){
                if (oldonload) {
                    oldonload();
                }
                func();
            }
        }
    }
</script>

This code is put below the functions you want to call onload, then you do something like:

if (($pageaction =="edit || $pageaction=="update") && $field_id != ""){
    echo "addLoadEvent(toggledisplaymode(\"$fieldtype\"));
}

This pretty much makes it so that when you edit the information, it at least shows the DIVs that where hidden (see code from previous posts to see what I'm talking about).

Now if I can just figure out how to put the variables that need to be edited in the proper place :facewall:

And if you are wondering I found the explanation for this here: http://www.webreference.com/programming/javascript/onloads/

March 15, 2010

Or you can do it this way:

<?php

$sleeves = array(
"15"=>"Long Sleeve",
"20"=>"Short Sleeve",
);

if (!isset($_POST['submit'])) {

?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF'];?>">
<select name="shirt" id="shirt">
<option value="" selected="selected">--- Select Sleeve Type ---</option>
<?php
   foreach($sleeves as $key => $value){
      echo '<option value="'.$key.'">'.$value.'</option>';
  }
?>
</select>
<input type="submit" name="submit">
</form>


<?php
} else {

$shType = $_POST["shirt"];
echo "This should work ".$sleeves[$shType];

}
?>

March 15, 2010

I believe that the only way that can be done is if your drop down was populated by a database or an array, or if your value is the same as your text. If you just typed the values and options in there yourself, then it will only read the value portion of the drop down box and you lose the other information.

<select id="dropdwn1" name="dropdwn1" size ="1">
  <option value="0" selected="selected">Choose</option>
  <option value="value1">value1</option>
  <option value="value2">value2</option>
</select>

or

$states = array(
  "AL"=>"Alabama",
  "AK"=>"Alaska",
  "AZ"=>"Arizona"
)

<select name="state" id="state">
  <option value="" selected="selected">--- Select State ---</option>
  <?
    foreach($states as $key => $value){
       echo '<option value="'.$key.'">'.$value.'</option>';
   }
  ?>
</select>

then you can get the information you wanted.

March 15, 2010

Okay, let's try to word this differently, mostly because I am at a loss. the original script (onChange script) toggles a couple of DIVs to display so that extra information can be put in. This onChange event is in a drop down list.

Now, when you go to EDIT that particular page, you can't see the extra options because there is no onChange event going on. My question is what should I do to call that function so that the extra information is shown? I have tried many things, but none of them worked and I am stumped.

I even tried something like this:

if (($pageaction=="edit" || $pageaction=="update") && $field_id !=""){
for($i=0; $i<count($options); $i++){ echo "<script type=\"javascript\">addOption(\"$options[$i]\")</script>"; }
echo "<script type=\"javascript\">toggledisplaymode(\"$fieldtype\")</script>";
}

right after the drop down list, since that is where the onChange takes effect, but it didn't work. Any other ideas?

March 15, 2010

Post your changed code. It may not be resetting the percent values, so it might just be running a total percentage based on how many times you do the quiz.

March 12, 2010

I think if you change these areas to your percent variable:


$uscore = $user->addChild('score',$_SESSION['score']); // <- Here


echo "<h2 id=\"score\">{$_SESSION['user']}, your final score is:</h2>\n
<h3>{$_SESSION['score']}/20</h3><h4>Verdict:</h4>"; // <- Here

And the same in your xml:

<?xml version="1.0" encoding="UTF-8"?>
<users>
  <user>
    <name>Bobby</name>
    <score>10</score> // <- Here
  </user>
  <user>
    <name>Billy</name>
    <score>1</score> // <- Here
  </user>
</users>

And in the leaders board:

function showLeaders($file,$limit,$group = null) {
    $leaders = array();
   
    // Load the xml file and place all users and associated
    // scores into the 'leaders' array.
    $xml = simplexml_load_file($file);
    foreach($xml->user as $user) {
        $name = (string)$user->name;
        $score = (string)$user->score; // <- Here
        $leaders[$name] = $score; // <- Here
    }
       
    // Sort the leaders array numerically, highest scorers first.   
    arsort($leaders,SORT_NUMERIC);
    
    // Initialise our $counter variable to '1'.
    $counter = 1;

// Start a html ordered list to hold the leaders.
    $output = "<ul class=\"leaders\">\n";
    
    // Loop through the 'leaders' array and wrap each username and score
    // in <li> tags. If the user is the current $_SESSION['user'], wrap
    // the name/score in <strong> tags too.
    foreach ($leaders as $key => $value) {
        // Check that $counter is less than $limit.
        if ($counter <= $limit) {
            if ($key == $_SESSION['user']) {
                $output .= "<li><strong>$key:</strong> $value/20</li>\n"; // <- Here
            } else {
                $output .= "<li>$key: $value/20</li>\n"; // <- Here
            }

Try changing those to your percentage value. i think that will take care of your problem. Oh, and take out the /20 that is there.

March 12, 2010

you said you had a text field where the editing was done. That is the field which needs the onblur attached to it, to detect when the editing is done

Being safe, and not wanting to offend, nowhere in my post did I say the editing was done in a text field.

Here is the Edit script:

echo "<td class=\"gridRow\" align=center>
<a href=\"index.php?component=contactform&page=wce.field.php&pageaction=edit&field_id=$myrow[0]&sortby=$sortby&sortseq=$sortseq&start=$start\"><img src=common/image/ico_edit.gif border=0 title=\"".$lang['contactform']['editthisrecord']."\"></a>  ";

It basically restarts the page and pre-fills in the form areas, but it won't show the hidden areas because the selection in the drop down box is already made. Since that uses an onChange to show those hidden areas, they will not be shown when in edit mode.

I had put the onBlur in the only text field there was and it didn't work there. Any other suggestions?

March 12, 2010

Ok I did get some code that shows a percentage. It shows it after the score out of 20 though. So it goes like " you scored 4/20 your percentage is 40"

First . . . your math function is a little off. 4 out of 20 is only 20% not 40%. You may try redoing your math function to something like this:

$scorePer = $right / $total;
$percent = $scorePer * 100;

For some reason your math function is working funny. I don't see how it got 40 percent.

As for doing it percent wise, try something like this:

if($_SESSION['percent'] <= 25) echo "<p id=\"verdict\"><span>S</span>everely <span>H</span>indered <span>I</span>n the <span>T</span>est!</p>\n";
if(($_SESSION['percent'] > 5) && ($_SESSION['percent'] <= 50)) echo "<p id=\"verdict\"><span>C</span>ould <span>R</span>ead <span>A</span>nd <span>P</span>ractice more.</p>\n";
if(($_SESSION['percent'] > 50) && ($_SESSION['percent'] <= 75)) echo "<p id=\"verdict\"><span>A</span>cronyms a<span>R</span>e <span>S</span>o <span>E</span>asy!</p>\n";
if($_SESSION['percent'] > 75) echo "<p id=\"verdict\"><span>S</span>uper <span>A</span>cronym <span>S</span>pecialist</p>";
echo "<p id=\"compare\"><a href=\"results.php\">See how you compare! <img src=\"images/arrow.png\" /></a></p>";
}

Basically, change $score to $percent and see if that works.

Hope that helps.

March 12, 2010

I would suggest onblur on the edit box

Ok. I put the onBlur in a couple of areas, hoping to get the right place.

First place I put it was on the link that sends it into edit mode . . . no results. There was no value set at that time for it.

Second place was in the

if ($pageaction=="edit" && $field_id != "")

section, because it should define the $fieldtype variable for the JS function to use . . . still no results.

Am I just putting it in the wrong place, or is my JavaScript-Fu that bad?

March 11, 2010

You are really gonna hit me, but where do I add that in the code?

That is a good question. My bets would be somewhere AFTER the score is tallied. Other then that, without seeing the whole thing, I wouldn't know where you'd put it. :shrug:

March 11, 2010

the simple answer would be to take the number they got right and divide it by the total number of questions.

$rightAnswer = $session['correct']; // Or whatever the code is for this.
$totalQuestions = $numberOfQuestions; // Same here.
$perc = $rightAnswer/$totalQuestions;

echo "You got ".$perc."% of the questions correct.";

March 11, 2010

Alright, so I got my onChange script to do what it is supposed in the dropdown, but how can I get it to work when they need to EDIT the options?

<tr>
<td valign=top width=28%><? echo $lang['contactform']['fieldtype'] ?></td>
<td>
	<select name="fieldtype" id="fieldtype" onChange="toggledisplaymode(this.options[this.selectedIndex].value)">
		<option value="textbox" <? echo $fieldtype=="textbox"?"selected":"" ?>><? echo $lang['contactform']['textbox'] ?></option>
		<option value="drop" <? echo $fieldtype=="drop"?"selected":"" ?>><? echo $lang['contactform']['dropdownselection'] ?></option>
		<option value="checkbox" <? echo $fieldtype=="checkbox"?"selected":"" ?>><? echo $lang['contactform']['checkbox'] ?></option>
		<option value="radio" <? echo $fieldtype=="radio"?"selected":"" ?>><? echo $lang['contactform']['radiobutton'] ?></option>
		<option value="textarea" <? echo $fieldtype=="textarea"?"selected":"" ?>><? echo $lang['contactform']['textarea'] ?></option>
	</select>
</td>
</tr>
<tr>
<td valign=top><? echo $lang['contactform']['fieldwidth'] ?></td>
<td><input type=textbox name=fieldwidth style="width:60px" value="<? echo $fieldwidth?$fieldwidth:"200" ?>"> px</td>
</tr>
<tr id="tbdataHeight" style="display:none">
<td valign=top><? echo $lang['contactform']['fieldheight'] ?></td>
<td><input type=textbox name=fieldheight style="width:60px" value="<? echo $fieldheight?$fieldheight:"50" ?>"> px</td>
</tr>
<tr id=tbrowOption style="display:none">
<td valign=top><? echo $lang['contactform']['fieldoptions'] ?></td>
<td>
	<table border=0 cellpadding=0 cellspacing=0 width=98%>
		<tr>
			<td><input name=optionvalue style="width:160px"> <input type=button value="<? echo $lang['contactform']['add'] ?>" onclick="addOption(document.thisform.optionvalue.value); document.thisform.optionvalue.focus();"> <input type=button value="<? echo $lang['contactform']['del'] ?>" onclick="deleteOption()"></td>
		</tr>
		<tr>
			<td><select size=5 name=options style="width:230px" onchange="populateItem(this.options[selectedIndex].index)"></select></td>
		</tr>
	</table>
</td>
</tr>

So when they make the selection to edit, it will automatically select the field, so the onChange event is basically canceled. I STILL need to show the hidden fields (as it is) so they can edit their contact, but I can't use the onChange. Any ideas on how I can call the function when they do an edit?e

Oh, the function code is:

function toggledisplaymode(selectType){

var tbrowOption = document.getElementById('tbrowOption');
var tbdataHeight = document.getElementById('tbdataHeight');

if (selectType=="drop" || selectType=="checkbox" || selectType=="radio"){
	tbrowOption.style.display = "table-row";
	tbdataHeight.style.display = "none";
}else if(selectType=="textarea"){
	tbrowOption.style.display = "none";
	tbdataHeight.style.display = "table-row";
}else{
	tbrowOption.style.display = "none";
	tbdataHeight.style.display = "none";
}
}

March 11, 2010

Hiding table columns can be tricky though, from my experience. What is it supposed to do when "working properly"?

When working properly it hides 2 options that won't be needed when you select a drop down box, radio buttons, or check boxes,. but shows options for what text could be put with those options.

Just tested the code, and it works to a degree. At least the hidden field is shown. Now I need to get it to hide the others.

EDIT Actually, apparently that did the trick. Thank you very much.

*bump*

March 10, 2010

Ok, it has been a while, but I am having a problem with some JavaScript. I can't locate the head and body tags, because the script is all template based. I have a function that is supposed to show some extra options when a selection is made from the drop down list, but it isn't working properly. Hopefully we can come to a solution together.

This is the code that has the drop down and the function call:

<tr><td valign=top width=28%><? echo $lang['contactform']['fieldtext'] ?></td>
<td colspan=3><input type=text name=fieldtext id=fieldtext style="width:265px" value="<? echo $fieldtext ?>"> *</td></tr>
<tr><td valign=top width=28%><? echo $lang['contactform']['fieldtype'] ?></td>
<td colspan=3>
<select name="fieldtype" id="fieldtype" onChange="toggledisplaymode(this.options[this.selectedIndex].value)">
	<option value="textbox" <? echo $fieldtype=="textbox"?"selected":"" ?>><? echo $lang['contactform']['textbox'] ?></option>
	<option value="drop" <? echo $fieldtype=="drop"?"selected":"" ?>><? echo $lang['contactform']['dropdownselection'] ?></option>
	<option value="checkbox" <? echo $fieldtype=="checkbox"?"selected":"" ?>><? echo $lang['contactform']['checkbox'] ?></option>
	<option value="radio" <? echo $fieldtype=="radio"?"selected":"" ?>><? echo $lang['contactform']['radiobutton'] ?></option>
	<option value="textarea" <? echo $fieldtype=="textarea"?"selected":"" ?>><? echo $lang['contactform']['textarea'] ?></option>
</select></td></tr>
<tr><td valign=top><? echo $lang['contactform']['fieldwidth'] ?></td><td><input type=textbox name=fieldwidth style="width:60px" value="<? echo $fieldwidth?$fieldwidth:"200" ?>"> px</td>
<td valign=top id=tbdataHeight1 style="display:none"><? echo $lang['contactform']['fieldheight'] ?></td><td id=tbdataHeight2 style="display:none"><input type=textbox name=fieldheight style="width:60px" value="<? echo $fieldheight?$fieldheight:"50" ?>"> px</td></tr>

<tr><td colspan=3>
<table id=tbrowOption style="display:none" border=0 cellpadding=0 cellspacing=0 width=98%>
<tr><td > blah blah text </td></tr>
</table>
</td></tr>

And this is the function code:

<script language=javascript>
function toggledisplaymode(selectType){

if (selectType=="drop"){
	tbrowOption.style.display = "block";
	tbdataHeight1.style.display = "none";
    tbdataHeight2.style.display = "none";
}else if(selectType=="textarea"){
	tbrowOption.style.display = "none";
	tbdataHeight1.style.display = "block";
     tbdataHeight2.style.display = "block";
}else{
	tbrowOption.style.display = "none";
	tbdataHeight1.style.display = "none";
     tbdataHeight2.style.display = "none";
}

}
</script>

There are other options for the if, but for now I am just trying to get it to work with the one.

And I am sorry for the messy code, I didn't write it, just trying to fix it.

Any help would be appreciated.

From what I understand, when I used to develop an online store, you have to pay a fee to use the paypal API

When I was creating APIs for working with PayPal, I never had to pay any fees. I have never had that problem. I know that a fee is taken when you GET money through PayPal, like a paycheck, but I never had to pay a fee to use the API.

March 10, 2010

You can get the API information from https://www.x.com/docs/DOC-1374. These should help you create the Paypal API for submitting the information you need. They used to have documentation to go with it, but I don't remember where to find it.

You can create a timer script that would log someone out after so much time of inactivity (requires Javascript) or you can create a script that will do a session_destroy() if they navigate away from the site.

October 9, 2008

put an id tag in the text areas and then you could use a little javascript to hide and show the fields.
