将复选框值存储在数据库中

Question

I'm working on the Administrator page for my website.

Administrator has the privilege to select six( 6 ) products and change the status from available to unavailable and vice versa, using check box .

Available products will be shown on the front-end for the user to see along with the picture of the product.

I have a table named used and has a column of value ( VarChar ).

Connection of both user and admin page to the database works fine. My problem is I'm not sure how to store the value of the selected check boxes , that would change the front end's output (picture of a product on the front-end will show up if product is available).

Here are my codes:

Admin (not sure at all how to do this)

Product 1
<input type="checkbox" name="product1" value="1">Available</span></input>

Product 2
<input type="checkbox" name="product2" value="1">Available</span></input>

User

<?php

require_once "../db_connect.php";

$res = mysqli_query("SELECT value FROM settings WHERE name='product1'",$mysql);

$row = mysqli_fetch_array($res);

$product1 = $row['value'];

$res = mysqli_query("SELECT value FROM settings WHERE name='product2'",$mysql);

$row = mysqli_fetch_array($res);

$product2 = $row['value'];


if ($product1 > 0)
    {
    echo '<img src="http://mysite/image1.png" border=0>';
    }
else 
    {
    echo '<img src="http://mysite/image2.png" border=0>';
    }

if ($product2 > 0)
    {
    echo '<img src="http://mysite/image3.png" border=0>';
    }
else 
    {
    echo '<img src="http://mysite/image4.png" border=0>';
    }

?>

for storing check box value use name attribute as

$check=$_POST['product1']; //it depend on you what method you are using

if you echo $check it will give 1
