[SOLVED] Name sets of radio buttons from array

[jself]

I'm currently searching the forum and halfway done, but not finding much too similar to my problem.

I am writing a very simple multiple choice quiz. Currently, I'm just doing a small test of it so I can get the mechanics working. Now, I do have a working quiz script I wrote and I have been trying to reference it's workings from. The difference is - the old quiz used associative arrays for questions/answers, which made writing questions/answers tedious (having to do like $q[$i]['c'] = "answer 1" and so on.

 

The new quiz uses the following format:

 

Question 1:,one,two,three,four
Question 2:,five,six,seven,eight
Question 3:,nine,ten,eleven,twelve

 

Practically a .CSV file. I HAVE tried fgetcsv and it seemed to work for spitting out the data as needed, but I've been having problems with the radio buttons so I have just been retooling my code, as such:

 

<FORM action="<?=$PHP_SELF?>" method="POST">

<?php

$file = file("ch1.csv");
foreach($file as $line){                                        // READ EACH LINE
$show = explode(",",$line);                                     // SPLIT ANSWERS
echo "<BR><B>" . $show[0] . "</B><BR>";                         // SHOW QUESTION
for($i=1; $i < count($show); $i++){                                        // LOOP ANSWERS

foreach($show as $value){
}
echo "<INPUT type='radio' name='$value' value='$value'>" . $show[$i] . "<BR>"; // SHOW ANSWERS
}
}

echo "<INPUT type='submit' name='submit' value='Submit!'><BR><BR>";

if(isset($_POST['submit'])){
echo $_POST[$value] . "<BR>";
}
else
{
}
?>
</FORM>

 

Problems:

- after hitting submit, it only displays 'twelve'. If I select any of the LAST 4 options (nine,ten,eleven,twelve), it will always say I chose "twelve". If I select any of the answers for the first 3 questions, it does not echo any chosen value back. The radio button's name needs to have an individual name per question/answer set. I'm unsure how to achieve this exactly.

 

In the script I have printed out the arrays so I can reference how they're seen, and there does seem to be a problem with $show, as it's only displaying the 3rd question/answer set.

 

I have just been going in circles over a week and confusing myself to exhaustion. It's got to be something simple!

 

Thanks.

*UPDATE*

 

I figured out how to get it to echo what you chose, but it's only working for the 3rd question set (i.e. it will now show if I chose any of it's answers). Updated code of LINE 14:

 

echo "<INPUT type='radio' name='$value' value='".$show[$i]."'>" . $show[$i] . "<BR>"; // SHOW ANSWERS

 

Now I need to figure out why it's only accepting input for the 3rd question, and not all consecutively... must be a loop issue.

try something like

<?php
$file = array (
    'Question 1:,one,two,three,four',
    'Question 2:,five,six,seven,eight',
    'Question 3:,nine,ten,eleven,twelve'
);

echo '<form>';
foreach ($file as $k => $line)
{
    $arr = explode (',', $line);
    $q = $arr[0];
    $a = array_slice($arr, 1, 4);
    
    echo $q;
    foreach ($a as $answer)
    {
        echo "<input type='radio' name='ans[$k]' value='$answer'> $answer ";
    }
    echo '<br/>';
}
echo '<input type="submit" name="sub" value="Submit">';
echo '</form>';

if (isset($_GET['sub']))
{
    foreach ($_GET['ans'] as $ans)
    {
        echo $ans, '<br/>';
    }
}
?>

Beautiful, that works very nicely! Thanks very much Will have a look through the code later to really grasp where I might've went wrong (very tired!).
