php - 从表单中检查外部数组

I've created a form in html. in this form you can specify the operating system. The form looks like this:

<input type="hidden" name="toshibaproduct" value="001"/>
<input type="hidden" name="toshibamerk" value="toshiba"/>
<input type="hidden" name="toshibamodel" value="Sattelite A100-510"/>
Operating system <select name="beschikbaarheid" value="true">
    <option value="xp">Windows XP</option>
    <option value="vista">Windows Vista</option>
    <option value="linux">Linux</option>
</select>
Aantal: <input type="text" size=2 maxlength=3 name="toshibaaantal" value="0"/>
<input type="hidden" name="toshibaprijs" value="999.99"/>
<input type="image" src="bestel.jpg" border=0 value="bestellen"/>

I've also created an external function which i have included in the page which looks like this:

<?php
function beschikbaarheid($merk, $os)
{
    $beschikbaar = array(
        "Toshiba" => array("xp" => true, "vista" => false, "linux" => true),
        "Acer" => array("xp" => true, "vista" => true, "linux" => true),
        "Hp" => array("xp" => true, "vista" => false, "linux" => true));
    return ($beschikbaar[$merk][$os]);
}
?>

My plan is to let the form check in the external function if an operating system is available or not, and if not return a message that it's sold out. if it's available it should just continue with the rest of the script (which works btw, but it not included here).

Thing is, i don't know how to make the form check the array in the external function. I am also wondering if it's a problem that only the operatings system is checked in an external function and not the rest of the form like the quantity for instance.

    Updated HTML

    <head>
    <!-- include jQuery -->
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
</head>

<input type="hidden" name="toshibaproduct" value="001" />
<input type="hidden" name="toshibamerk" value="toshiba" />
<input type="hidden" name="toshibamodel" value="Sattelite A100-510" />
Maker
<select name="maker" value="true" id="maker">
    <option value="toshiba">Toshiba</option>
    <option value="acer">Acer</option>
    <option value="hp">Hp</option>
</select>
Operating system 
<select name="beschikbaarheid" value="true" id="operationSystem">
    <option value="xp">Windows XP</option>
    <option value="vista">Windows Vista</option>
    <option value="linux">Linux</option>
</select>
Aantal: <input type="text" size=2 maxlength=3 name="toshibaaantal" id="quantity" value="0" />
<input type="hidden" name="toshibaprijs" value="999.99" />
<input type="button" value="bestellen" id="submitData" />

<span id="messages"></span>

    Ajax

    <!-- Ajax -->
<script type="text/javascript">
$('#submitData').click(function(){
    var selectedOs = $('#operationSystem').find('option:selected').val();
    var selectedMaker = $('#maker').find('option:selected').val();
    var selectedQuantity = $('#quantity').val();
    if(selectedQuantity == 0 || selectedQuantity == ''){
        $('#messages').text('Please provide valid information');
        return false;
    }
   // You can perform an ajax request using the .ajax() method
    $.ajax({
        type: 'POST',
        url: 'beschikbaarheid.php', // This is the url that will be requested
        data: {operation_system: selectedOs, maker: selectedMaker, quantity: selectedQuantity},
        success: function(data){ 
            if(data){
                $('#messages').text('Available');
            }else{
                $('#messages').text('Not available');
            }
        },
    });

});
</script>

    Server-side script (beschikbaarheid.php)

    <?php
if(isset( $_POST['quantity'] )) {
    $operatingSystem  = $_POST['operation_system'];
    $maker  = $_POST['maker'];
    $quantity  = $_POST['quantity'];
    echo beschikbaarheid($operatingSystem, $maker, $quantity);
}
function beschikbaarheid($operatingSystem, $maker, $quantity)
{
    // I did't used the quantity section
    // Please use it if needed
    // Also this structure is not much prefered, I just used this becasuse you might have some out put like this.
    $beschikbaar = array(
        "toshiba" => array ("xp" =>false, "vista" => false, "linux" => true), 
        "hp" => array ("xp" =>true, "vista" => false, "linux" => true),
        "acer" => array ("xp" =>true, "vista" => false, "linux" => true)
    ); 
    return $beschikbaar[$maker][$operatingSystem];
}
?>

    There are different ways to achieve this, I hope this helps.
