Question And Answer submit
Hi! I have a page with outputs questions from a database, and the user can select an answer..
all the answers are collected in a $answers array which is sent to the next page like this
Code:
<select name="answers[]"> ... </select>
Now how can i also send the Questions array to the next page..
a hidden input field cannot hold an array that easy and if i use a while loop to create many hidden fields, they all have a different name.
Anyone that can help me out please!
thanks

They will not have different names if you create the names in the loop as well.
PHP Code:
echo "<select name=\"questions[$i]\">...</select>";

You can include the ID in the form's post method:
Code:
<form method="POST" action="checkAnswer.php?question=<?php echo $questionId; ?>">
You can also use the session.
You can also name the questions array with the answer ID:
Code:
<select name="answers[<?php echo $questionId; ?>][]"> ... </select>

I tried the second idea and it's just outputting the $row['vraag_id']
Code:
<select name="antwoord[ <?php echo $row['vraag_id'] ?> ] [] ">

If that is the case then you probably have quotes messed up somewhere. It is treating the $row variable as a literal string. Post all your code and use [ PHP ] tags. See the sticky at the top of this forum.

This is the PHP.
PHP Code:
<select name="antwoord[ <?php echo $row['vraag_id'] ?> ] [] ">
And this is how i'm trying to test-fetch it
PHP Code:
$antwoorden = $_POST['antwoord'];
print_r($antwoorden);

What is the resulting HTML for this PHP output?
What's the result of print_r($_POST)?

Thanks for your help! I managed to get to this
PHP Code:
echo '<select name="antwoord['.$vraagid.'][]">';
Which results in this
Code:
Array ( [antwoord] => Array ( [135] => Array ( [0] => 6 ) [137] => Array ( [0] => 0 ) ) )
But how can i get this result to show like this
Code:
[135] => 6 [137] => 0
Thanks!

Hi,
by leaving out the "[]" at the end of the input name. It's useless, anyway.

It's fixed! Thanks a lot for the help!
Using
PHP Code:
foreach($_POST['antwoord'] as $vraag => $antwoord){ ... }
