Adding binary checkbox values to MySQL database using PHP

I'm new to PHP, and I am creating a basic CMS using PHP and MySQL. I'm struggling to get the checkbox information from my HTML page across into the database.

How can I make the values to appear as binary 0 or 1 values?

The HTML document is written as follows:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"&gt;
<html>
    <head>
        <title>Create your news page</title>
        <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
    </head>
    <body>
        <fieldset>
            <legend>Checked components will show in the page</legend>
            <form method="POST" action="http://*********.php"&gt;
                <span class="label">Header</span>
                <input type="checkbox" name="header" value="HEADER">
                <br>
                <span class="label">Footer</span>
                <input type="checkbox" name="footer" value="FOOTER">

                <hr>
                <span class="label">Local news</span>
                <input type="checkbox" name="local" value="LOCALNEWS">
                <br>
                <span class="label">National news</span>
                <input type="checkbox" name="national" value="NATIONALNEWS">
                <br>
                <span class="label">International news</span>
                <input type="checkbox" name="international" value="INTERNATIONALNEWS">
                <p>
                <input type="submit">
            </form>
        </fieldset>
    </body>
</html>

And the PHP document is written as follows:

<?php
    $user="user_***";
    $password="*********";
    $database="dbxyz";
    mysql_connect("localhost", $user, $password);
    mysql_select_db($database, $db_handle);
    mysql_select_db("dbxyz");
    if(isset($_POST['layout']))
    {
        foreach($_POST['layout'] as $value {
            $insert="INSERT INTO layout (header, footer, local, national, international) VALUES ('$value')";
            mysql_query($insert);
        }
    }
?>

I think you're looking for the MySQL 'BOOL'-datatype...

Edit: Your code is actually loaded with syntax/code errors... I don't believe this actually runs. Can you paste the original here?

Make the field which will store the values in your table TINYINT(1), check the status of the checkbox upon submit by comparing $_POST['nameOfCheckboxField'] with 'on', if it evaluates to true, put 1 in your db field, otherwise put 0.

You are supposed to put all the values in the query at once.
It can be done like that:

$values = array(
    'header'        => null,
    'footer'        => null,
    'local'         => null,
    'national'      => null,
    'international' => null
);

foreach (array_intersect_key($_POST, $values) as $key => $value) {
    $values[$key] = mysql_real_escape_string($value);
}

mysql_query("INSERT INTO layout (header, footer, local, national, international) VALUES ('$values[header]', '$values[footer]', '$values[local]', '$values[national]', '$values[international]')");

Also, notice the mysql_real_escape_string call. It escapes all the characters of its parameter that can be used for SQL injections.

And yes, like the previous posters have said, you should convert the checkbox values to 1 or 0 and then save in a tinyint field.

A: 

If checkboxes aren't checked in a form, then the key/value pair isn't sent when the form is submitted, thus you need to check if each is set. So:

$header = isset($_POST['header']) ? 1 : 0;

This variable will be 1 if the 'header' box was checked, else it will be 0.

$header        = isset($_POST['header']) ? 1 : 0;
$footer        = isset($_POST['footer']) ? 1 : 0;
$local         = isset($_POST['local']) ? 1 : 0;
$national      = isset($_POST['national']) ? 1 : 0;
$international = isset($_POST['international']) ? 1 : 0;

$insert = "INSERT INTO layout (header, footer, local, national, international)
           VALUES ($header, $footer, $local, $national, $international)";

mysql_query($insert);

I have a similar query.

Can I ask, what would I need to type into the mysql database to store this data into my table?
