checkbox array

Hi all, when inserting values stored in an array to MySQL database, where do the values go?

I have a form with 5 checkboxes that may or may not be checked, their names all being an array.

Question: how do I write the sql file?

assuming the names are nature[]

would I need to do this...

nature varchar(50) null

Plz help!

Hi thanks for the response, but my question still stands...

Where do the values get stored in the database?

Surely there must be a column defined in the sql file that has a name, a data type, how many characters are expected, can it be blank, etc...

Like I said, would I need to do this...? nature varchar(50) null It is this part that I don't get.

ok I'm gonna add some code here, maybe this will clarify what I am trying to do...

register.php

<input type="text" name="firstName" value="<?php echo $form->value("firstName"); ?>" />
<input type="text" name="lastName" value="<?php echo $form->value("lastName"); ?>" />
<input type="checkbox" name="nature[]" value="0" />
<input type="checkbox" name="nature[]" value="1" />
<input type="checkbox" name="nature[]" value="2" />

process.php

$retval = $session->register($_POST[firstName], $_POST['lastName'] ($question = implode(",",$_POST['questions'])));

session.php

function register($subfirstname, $sublastname, $subquestion) {
     // firstname error checking

     // lastname error checking

     // Errors exist, have user correct them
     if($form->num_errors > 0) {
          return 1; // Errors with form
     }
     else {
          if($database->addNewUser($subfirstname, $sublastname, $subquestion)) {
               return 0; // New user added successfully
          }
          else {
               return 1; // Registration failed
          }
     }
}

database.php

function addNewUser($firstname, $lastname, $questions) {
     $q = "INSERT INTO users VALUES ('$firstname', '$lastname', $questions)";
     return mysql_query($q, $this->connection);
}

tables.sql

DROP TABLE IF EXISTS users

CREATE TABLE users (
     firstname   varchar(30) not null,
     lastname    varchar(30) not null
);

========

you will notice that the tables.sql does not have a column defined for questions. Should there be one?

Areas that I am not sure about are the sql and the formatting of the implode in process.php

Please help me someone if you can,

thanks.

hi,
create a new row in database call it as nature and write like this

$string = implode(",",$_POST['nature']);

$query = "insert into table (nature) values ('$string')";

mysql_query($query);

it will inset the values into database with comma seperated
