Prossessing checkbox value in a php form connected to mysql database - php

Question

Hi I am trying to create a form for the school I work so that staff can book when they want a projector setting up in the school hall. So far i have textbox fields for date, time, name but I also want a checkbox field so they can select if they want to loan a laptop and have sound.
My problem is I can't find how to put the value from the checkbox into the database. Thanks in advance for any help.
Here is what I have so far...
HTML
<form action="mysql-insert.php" method="post">
<p>Date: <input name="date" type="text" id="datepicker" /></p>
<p>Time : <input name="time" type="text" /></p>
<p>Name : <input name="name" type="text" /></p>
<p>Laptop <input name="chkbox[]" type="checkbox" value="Laptop" /></p>
<p>Sound <input name="chkbox[]" type="checkbox" value="Sound" /></p>
<p><input name="submit" type="submit" value="Save Hall Setup Request" /></p>
</form>
PHP
<?php
$dbserver = 'localhost';
$dbuser = 'root';
$dbpassword = '';
$dbdatabase = 'hall_setup';
$cn = mysql_connect($dbserver , $dbuser, $dbpassword);
if (!mysql_select_db($dbdatabase, $cn)) {
echo "Sorry, could not connect to $dbdatabase";
die();
}
if (!isset($_POST['submit'])) {
header("Location: mysql-insert-form.php");
die();
}
$date = $_POST['date'];
$time = $_POST['time'];
$name = htmlspecialchars(trim($_POST['name']));
$laptop = $_POST['chkbox'];
$name = mysql_real_escape_string($name);
$sql = "INSERT INTO laptoprequest
(date, time, name, laptop)
VALUES
('$date', '$time', '$name', '$laptop')";
if(!mysql_query($sql, $cn)) {
print "Error - data not submitted";
die();
};
header("Location: hall_setup.php");
?>

<?php
<input type="checkbox" name="check_list[]" value="English" required>
<label>English</label>
<input type="checkbox" name="check_list[]" value="Non English" required>
<label>Non English</label>
<input id="button" type="submit" name="submit" value="Submit">
?>
//above question for answer this..>>>
<?php
$checkbox = $_POST['check_list'];
if($_POST["submit"]=="submit"){
for($i=0;$i<sizeof($checkbox);$i++){
$query1="INSERT INTO user(language) VALUES
('".$checkbox[$i]."')";
mysql_query($query1) or die(mysql_error());
}
echo "Record is inserted.."
}
?>
