Cant get script to sum up the number of correct answers

[chrisdee]

Hello. Below Iv made a script wich asks 3 questions,
and if all 3 are correct it should sum up one point
for each correct answer. But it doesnt work.
I only get one correct answer at the end.
Would greatly apreciat help on this.
Here is my script :

<?php 
$woman = array('Anette Sagen','Line Jahr','Henriette Lien'); 
$w = $_POST['w']; 
$men = array('Matti Nykanen','Sven Hannawald','Bjørn Wirkola'); 
$m = $_POST['m']; 
$land = array('Norway','Finland','Germany'); 
$l = $_POST['l']; 

if (empty($_POST)) { 
 echo "Who won the womans jump week in 2004 ?"; 
 echo "<form method=post action=$_SERVER[PHP_SELF]>"; 
  foreach($woman as $w) { 
   echo "<input type=radio name=w value='$w'>$w<br>"; 
  } 
  echo "<input type=submit value=Answer>"; 
  echo "</form>"; 
} 
elseif($w==$woman[1] or $w==$woman[2]) { 
 echo "$w is wrong answer.<br>"; 
 echo "<a href=$_SERVER[PHP_SELF]>Try again</a>"; 
} 
elseif($w==$woman[0]) { 
 echo "$w is correct.<br>"; 
 echo "Who is the king of the jumpweek ?"; 
 echo "<form method=post action=$_SERVER[PHP_SELF]>"; 
  foreach($men as $m) { 
   echo "<input type=radio name=m value='$m'>$m<br>"; 
  } 
  echo "<input type=submit value=Answer>"; 
  echo "</form>"; 
 } 
elseif($m==$men[0] or $m==$men[1]) { 
 echo "$m is the wrong answer.<br>"; 
 echo "<a href=$_SERVER[PHP_SELF]>Try again</a>"; 
} 
elseif($m==$men[2]) { 
 echo "$m is correct.<br>"; 
 echo "Wich country has most victories ?"; 
 echo "<form method=post action=$_SERVER[PHP_SELF]>"; 
  foreach($land as $l) { 
   echo "<input type=radio name=l value='$l'>$l<br>"; 
  } 
  echo "<input type=submit value=Answer>"; 
  echo "</form>"; 
} 
elseif($l==$land[0] or $l==$land[2]) { 
 echo "$l is the wrong answer.<br>"; 
 echo "<a href=$_SERVER[PHP_SELF]>Try again</a>"; 
} 
else { 
 echo "$l is correct.<br>"; 
 $result = ($l + $m + $w); 
 echo "You have ".count($result)." points!<br>"; 
 echo "<a href=$_SERVER[PHP_SELF]>Try again</a><br>"; 
} 
?>

The correct answers prior to the last one are not being preserved across each submission.

How do i do this ?

[Weedpacket]

[man]Session[/man] functions were made for that sort of thing.

Iv tried to modify the script with hidden fields but I still cant get it to work.
Below is the script :

<?php
$woman = array('Anette Sagen','Line Jahr','Henriette Lien');
$menn  = array('Matti Nykanen','Sven Hannawald','Bjørn Wirkola');
$w = $_POST['w'];
$m = $_POST['m'];
$result1 = $_POST['1'];
$result2 = $_POST['1'];

if(empty($_POST)) {
 echo "Who won the womans jumpweek ?<br>";
 echo "<form method=post action=$_SERVER[PHP_SELF]>";
 foreach($woman as $w) {
  echo "<input type=radio name=w value='$w'>$w<br>";
 }
 echo "<input type=hidden name=result1 value=$result1>";
 echo "<input type=submit value=Answer><br>";
 echo "</form><br>";
}
elseif($w==$woman[0]) {
 echo "Who is the king of the jump week ?<br>";
 echo "<form method=post action=$_SERVER[PHP_SELF]>";
 foreach($menn as $m) {
  echo "<input type=radio name=m value='$m'>$m<br>";
 }
 echo "<input type=hidden name=result2 value=$result2>";
 echo "<input type=submit value=Answer><br>";
 echo "</form><br>";
}
elseif($m==$menn[2]) {
 $result = $result1 + $result2;
 echo "You have $result points!<br>";
 echo "<a href=$_SERVER[PHP_SELF]>Try again</a><br>";
}
else {
 echo "$w $m is wrong answer!<br>";
 echo "<a href=$_SERVER[PHP_SELF]>Begin again</a><br>";
}
?>

Why are you using hidden fields? Save it as a session variable.
Your script will be much more safer.

That is not a good programming practice 😉 (I can see the result doing: View->Source Code in my browser, and your script can't support new questions easily...).

I tried to modify the script to use sessions but for some reason I still cant get it
to remember the previous state and add up the correct number of answers.
What am I doing wrong here ?

<?php
$woman = array('Anette Sagen','Line Jahr','Henriette Lien');
$menn  = array('Matti Nykanen','Sven Hannawald','Bjørn Wirkola');

session_start();
session_register('w');
session_register('m');

$w = $_POST['w'];
$m = $_POST['m'];

if(empty($_POST)) {
 echo "Who won the womans jumpweek ?<br>";
 echo "<form method=post action=$_SERVER[PHP_SELF]>";
 foreach($woman as $w) {
  echo "<input type=radio name=w value='$w'>$w<br>";
 }
 echo "<input type=submit value=Answer><br>";
 echo "</form><br>";
}
elseif($w==$woman[0]) {
 echo "Who is the king of the jump week ?<br>";
 echo "<form method=post action=$_SERVER[PHP_SELF]>";
 foreach($menn as $m) {
  echo "<input type=radio name=m value='$m'>$m<br>";
 }
 echo "<input type=submit value=Answer><br>";
 echo "</form><br>";
}
elseif($m==$menn[2]) {
 $result = $w + $m;
 echo "$w<br>";
 echo "$m<br>";
 echo "You have ".count($result)." points!<br>";
 echo "<a href=$_SERVER[PHP_SELF]>Try again</a><br>";
}
else {
 echo "$w $m is wrong answer!<br>";
 echo "<a href=$_SERVER[PHP_SELF]>Begin again</a><br>";
}
?>

I finally solved it. I had to assign an additional variable. Below is the working
code 🙂

<?php
$woman = array('Anette Sagen','Line Jahr','Henriette Lien');
$menn  = array('Matti Nykanen','Sven Hannawald','Bjørn Wirkola');
$w = $_POST['w'];
$w1 = $_POST['w1'];
$m = $_POST['m'];

if(empty($_POST)) {
 echo "Who won the womans jumpweek ?<br>";
 echo "<form method=post action=$_SERVER[PHP_SELF]>";
 foreach($woman as $w) {
  echo "<input type=radio name=w value='$w'>$w<br>";
 }
 echo "<input type=submit value=Answer><br>";
 echo "</form><br>";
}
elseif($w==$woman[0]) {
 echo "Who is the king of the jump week ?<br>";
 echo "<form method=post action=$_SERVER[PHP_SELF]>";
 foreach($menn as $m) {
  echo "<input type=radio name=m value='$m'>$m<br>";
 }
 echo "<input type=hidden name=w1 value='$w'>";
 echo "<input type=submit value=Answer><br>";
 echo "</form><br>";
}
elseif($m==$menn[2]) {
 $result = (count($w1) + count($m));
 echo "You have $result correct answers!<br>";
 echo "<a href=$_SERVER[PHP_SELF]>Try again</a><br>";
}
else {
 echo "$w $m is wrong answer!<br>";
 echo "<a href=$_SERVER[PHP_SELF]>Begin again</a><br>";
}
?>
