Hello. I have a small problem. I am working on a small website where people will be able to take quizzes for driving lessons. I take my questions and answers from a database. The problem is that i get the first questions and after i submit the answers, the next question won't appear. I don't know what to do. Here is my php code:
<?php
include('db.php');
$query = "SELECT * FROM intrebari";
$exec = mysql_query($query);
$nt = mysql_fetch_array($exec);
$id = "$nt[id_question]";
$currentid = intval($id[0]);
echo "Intrebarea numarul $id";
$next = mysql_query("SELECT id_question FROM intrebari WHERE id_question > $id ORDER BY id_question ASC LIMIT 1");
if (mysql_num_rows($next) > 0){
$nextid = mysql_result($next, 0);
}
echo "$nextid";
?>
<html>
<body>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<?php echo "$nt[question]"; ?><br>
<input type="checkbox" name="q1[]" value="a" /><?php echo "$nt[answer_a]"; ?><br>
<input type="checkbox" name="q1[]" value="b" /><?php echo "$nt[answer_b]"; ?><br>
<input type="checkbox" name="q1[]" value="c" /><?php echo "$nt[answer_c]"; ?><br>
<input type="submit" name="id[<?php echo $nextid?>]" value = "Trimite" />
</form>
</body>
</html>
<?php
$rspcorecte = 0;
$rspincorecte = 0;
$corect = "$nt[correct_answer]";
$aux="";
if(isset($_POST['q1']))
for($i=0; $i < count($_POST['q1']); $i++)
$aux=$aux.$_POST['q1'][$i];
if ($aux == $corect) {
//echo "corect";
$rspcorecte++;
header("location: index.php?id=$nextid");
}
else{
$rspincorecte++;
//echo "gresit";
//header("location:");
}
?>and my database table look like this:
CREATE TABLE IF NOT EXISTS `intrebari` (
`id_question` int(11) NOT NULL AUTO_INCREMENT,
`question` text NOT NULL,
`answer_a` text NOT NULL,
`answer_b` text NOT NULL,
`answer_c` text NOT NULL,
`correct_answer` varchar(10) NOT NULL,
PRIMARY KEY (`id_question`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=5 ;Sorry for my bad english, it is not my primary language. Regards, Darius
