now i'm fetching questions and their respective options from database.
so i'want to save the option in seesions or cookies when ever user selected.
this is my code for fetching questions & ANSWERS.

public function display( )
$query="SELECT * FROM test  ORDER BY RAND() limit 5  ";
$result=mysql_query($query)or die("cannot select DB");
while($row = mysql_fetch_array($result))


$id=join("," qid);
$query="SELECT * FROM test  where qid="$id";
$result=mysql_query($query)or die("cannot select DB");
echo "<table>";
echo "<tr>"."<td style='overfolw-hidden;width:400px;'> Question: </td>";
echo "<td style='overfolw-hidden;width:40px;'> OPTION A </td>";
echo "<td style='overfolw-hidden;width:40px;'> OPTION B </td>";
echo "<td style='overfolw-hidden;width:40px;'> OPTION C </td>";
echo "<td style='overfolw-hidden;width:40px;'> OPTION D </td>";
echo "</tr>";
while($row = mysql_fetch_array($result))
echo "<td>" . $row['question'] . "</td>";
echo "<td>$row[a]<input type='radio' name='$row[qid]' value='$row[a]'> </td>";
echo "<td>$row[b]<input type='radio' name='$row[qid]' value='$row[b]'> </td>";
echo "<td>$row[c]<input type='radio' name='$row[qid]' value='$row[c]'> </td>";

You have some errors in your code:
- missing $ character at variable names for $i, $qid
- if qid is not a variable but rather an associative index it should be always enclosed within quotes
- the name of the $_SESSION array is misspelled (it is not $_SEESION)

The code won't work until you fix those errors.

To make sure I understand your question correctly:

  • you display 5 random questions from a database + several optional answers for each question (like a quiz where you chose one or more answers for each question)
  • then you want to store the chosen answers in session

Please confirm that this is what you want. And post the structure of the test table.

Why do you want to store the checked answers in the session? Do you intend to use them on many pages? If you want to display the results there is usually no need to store the answers in session. If you want to keep the results for longer it might be better to store the answers in database.

<td> question1 </td>
<td> option a </td>
<td> option b </td><td> option c </td><td> option d </td>
<td> question2 </td>
<td> option a </td>
<td> option b </td><td> option c </td><td> option d </td>
<td> question3 </td>
<td> option a </td>
<td> option b </td><td> option c </td><td> option d </td>
<td> question4 </td>
<td> option a </td>
<td> option b </td><td> option c </td><td> option d </td>
<td> question5 </td>
<td> option a </td>
<td> option b </td><td> option c </td><td> option d </td>

all options should kept in radio buttons & the question should be in text box.
here the user can have chance to select a single optioin for single question.i want to save that answer in sessions.is it possible for storing the selected radiuo button value.if possible can u please help with that piece of code. all 5 tables wiulkl generate dynamically using while loop.these are fetching from mysql.


In order to help you please post the structure of the tables with questions and answers.


OK, I have prepared a conceptual answer to your question. I hope this is what you are after. See the comments in the code.

// if the form has been submitted, set the session
if(isset($_POST['submit'])) {

    // reset the previous values
    $_SESSION['quiz'] = array();

    // get rid of the submit element in the $_POST
    // so you are left with only radio buttons values

    // assign the values of the radio buttons to the $_SESSION['quiz'] array
    $_SESSION['quiz'] = $_POST;

// connect to database (use your connection code)
require_once 'dbconnect.php';
$link = dbConnect();

// initialize an array for randomly selected question IDs
$qid_arr = array();

// select random question IDs
$qquery = "SELECT `qid`, `question` FROM `test` ORDER BY RAND() LIMIT 5";
$qresult = mysqli_query($link, $qquery) or die("cannot query DB");

// form
echo '<form method="post" action="#">';

// table
echo '<table border="0">';

// display randomly selected questions 
while($qrow = mysqli_fetch_assoc($qresult)) {

    // code for textbox containig question
    $tb = '<input type="text" value="' . $qrow['question'] . '" />';

    // select optional answers for this question from the database
    $aquery = "SELECT `option`, `answer` FROM opt_answers WHERE qid={$qrow['qid']}";
    $aresult = mysqli_query($link, $aquery) or die("cannot query DB");

    // start the html table row
    echo "<tr><td>$tb</td></tr>";

    // ad a question and optional answers
    while($arow = mysqli_fetch_assoc($aresult)) {

        // name atribute for checkbox
        $cb_name = 'question-' . $qrow['qid'];

        // code for radio button
        // checkbox group name is question-1 for 1st question etc
        // checkbox value equals the letter of the optional answer
        $cb = '<input type="radio" name="' . $cb_name . '" value="' . $arow['option'] . '" />';

        // display the row
        echo "<tr><td>{$cb} {$arow['option']}) {$arow['answer']}</td></tr>\n";

echo '</table>';

// submit button
echo '<input type="submit" name="submit" value="Submit">';

echo '</form>';

// for testing purpose only
// display the value of $_SESSION
if(isset($_SESSION)) {

    echo '<p><pre>';
    echo '**************************************<br />';
    echo print_r($_SESSION, 1);
    echo '**************************************';
    echo '</pre></p>';    

The code above is just a concept. It could be optimized (e.g. using JOIN).

hi broj1 :-)
he was asked about the storing the values in sessions when the radio buttons was checked is it possible for that in php?


And there is a small glitch in the code. The database connection part of the code should be moved on top. Sorry about that.
