php / mysql and forms variables

romano2717 · February 19, 2008

I need help to this problem that i've been tackling for quite a few days now..

see, I made a database driven quiz, wherein questions and choices are saved and retrieve in the database.

the choices are displayed beside the radio button, there will be four radio buttons per question.

the problem now is I dont know how to get the checked values of my radio buttons. I think i have something to change in my form with the way i name my form variables.. is there a way to display the checked values of the radio buttons? please i really need help.. cheers! heres the code.

<?php

session_start();

//connect to database

include('connect.php');

//initz variables

$made = $_SESSION['inst'];

$topic = $_SESSION['topic'];

$num = $_SESSION['num'];

$sql = " SELECT * FROM questionnaires_table WHERE made = '".$made."'

AND topic = '".$topic."' LIMIT $num";

$result = mysql_query($sql)or die("query failed, di mka fetch".mysql_error());

$count = mysql_num_rows($result);

?>

<html>

<head><title>OIPLT evaluation</title></head>

<body>

<?php

echo '<form method="get" action="evaluate_score.php">

<table align = "center" border = "1" width = "75%">';

if($_GET['start']){

while($row = mysql_fetch_assoc($result)){

$a = $row['a'];

$b = $row['b'];

$c = $row['c'];

$d = $row['d'];

$ques = $row['ques'];

$quesId = $row['quesId'];

echo'

<tr>

</tr>

<tr>';

echo" <td align = 'left'>

<input type = 'radio' name=q$quesId value='$a'>{$a}

</td>

</tr>";

echo" <tr>

<input type = 'radio' name=q$quesId value='$b'>{$b}

</td>

</tr>";

echo " <tr>

<input type = 'radio' name=q$quesId value='$c'>{$c}

</td>

</tr>";

echo" <tr>

<input type = 'radio' name=q$quesId value='$d'>{$d}

</td>

</tr>";

}

echo "

<tr>

</tr>

</table>";

?>

</form>

</body>

</html>
