$.ajax({

type: "POST",
url: "include/submit.php",
dataType : 'json',
data: {filterTypeOpts: typeopts,child: 179},
cache: false,
success: function(data){

$('#disp').html(makeTable(data));

}

});
}

echo $typeopts = isset($_POST['filterTypeOpts'])? $_POST['filterTypeOpts'] : array('');
echo $ctemp = $_POST['child'];

Rewrite your function as

JavaScript

function updateProduct(typeopts){
    $.ajax({
        type: "POST",
        url: "include/submit.php",
        dataType : 'json',
        data: {filterTypeOpts: typeopts,child: 179},
        cache: false,
        success: function(data){
            $('#disp').html(makeTable(data));

        }
        error: function(err){
            $("#error_window").html(err.responseText);
        }
    });
}

Also make a div with id error_window; This will help you to understand, what went wrong
finally

PHP

//i am guessing $_POST['filterTypeOpts'] is an array. Your php is suppose to screw up here. 
echo $typeopts = isset($_POST['filterTypeOpts'])? $_POST['filterTypeOpts'] : array('');

Another possible error you would face is, you are echoing or printing non JSON text. Even if your php works properly and your server response with status code 200 but yet your JQuery will through the result in error status.
