rent php/html update form spg.

Hej!
Jeg har en php side hvor jeg præsentere data i nogle input tedstbokse. Dette gør for dig jeg gerne vil lave en update knap der opdatere i db hvis jeg ændrfe i en tekstbox og trykker på knappen update.

Mit problem er at jeg kan sagtens putte det hele ind i en form og kalde et andet php script og derved opdatere men record.

Men jeg ville jo gerne hvsi man kunne laver det så smart at jeg kunne blive på siden og bare kalde en function med de rette parametre og opdatere on the fly.. Mit script er ret stort og ret rodet. Men her er det.

<?php


require ("header.php");
include ("functions.php");
$mindrop = $_GET["mindrop"];
$i=1;
$customerData = getCustomerData($mindrop);
      foreach ($customerData as $customer) {

            if($i==1) {
                echo "<br>";
                echo "<table class=\"noColor\">";



                echo "<td><b> Customer:</b></td><td><input type = \text\" value =\" " .$customer['customer'].  "\"></td><tr>";
                echo "<td><b>Address:</b></td><td><input type = \text\" value =\" " .$customer['address']. "\"></td><tr>";
                echo "<td><b>Zipcode:</b></td><td><input type = \text\" value =\" " .$customer['zipcode']. "\"></td><tr>";
                echo "<td><b>City:</b></td><td><input type = \text\" value =\" " .$customer['city']. "\"></td><tr>";
                echo "<td><b>Phone:</b></td><td><input type = \text\" value =\" " .$customer['phone']. "\"></td><tr";
                $customerId=$customer['id'];
                $customerName=$customer['customer'];
