Question

I have the following checkboxes:

[] Jackets
[] Jeans
[] T-Shirts
[] Shoes
[submit button]

When the user, for example, checks [x] Jackets and [x] T-shirts and clicks [submit button], the form will send a post request to itself. Then, somehow a dynamic query is generated based on the check boxes selected, and then only the selected categories will be queried..then displayed on the page.

The problem that I am having is trying to create the query dynamically after the post request.

Answer 1

// options
$options = array(
    'Jackets' => 'jackets', 
    'Jeans' => 'jeans', 
    'T-Shirts' => 't_shirts', 
    'Shoes' => 'shoes'
);

// create sql where
$sql_where = array('1');
foreach ($options as $option)
{
    if (isset($_POST[$option])) $sql_where[] = "field = '$option'";
}

// query data
mysql_query("SELECT * FROM table WHERE " . implode(' AND ', $sql_where));

// create html
$sql_where = array('1');
foreach ($options as $name => $option)
{
    ?>
        <input type="checkbox" name="<?= $option?>" id="<?= $option?>" value="1" />
        <label for="<?= $option?>"><?= $name?></label>
    <?
}
