Hi all,
I'm trying to create some XML from PHP code to save data about customers, but I
found many problem and it doesn't work.
The class Customer is quite simple I put it right below
<?php
class customer {
var $name;
var $phone;
function customer($name, $phone) {
$this->name = $name;
$this->phone = $phone;
}
function getName() {
return $name;
}
function setName($name) {
$this->name = $name;
}
function getPhone() {
return $phone;
}
function setPhone($phone) {
$this->phone = $phone;
}
function addXMLCustomer($dom, $root) {
$customer = $dom->createElement('customer');
$name_at = $dom->createAttribute('name');
$customer->appendChild($name_at);
$name_at_val = $dom->createTextNode($this->name);
$name_at->appendChild($name_at_val);
$phone_at = $dom->createAttribute('phone');
$customer->appendChild($phone_at);
$phone_at_val = $dom->createTextNode($this->phone);
$phone_at->appendChild($phone_at_val);
$root->appendChild($customer);
}
}
?>
the main page is simply a little form asking to introduce a new customer....
(the problem is not when you try to create the XML file for the first time, but
something on getElementsByTagName, that is when you try to reopen the file...
for example for a second customer....
<html>
<head>
<title>MCare administration</title>
<script type="text/javascript"
src="script/scriptaculous-js-1.8.2/prototype.js"></script>
<script type="text/javascript"
src="script/scriptaculous-js-1.8.2/scriptaculous.js"></script>
</head>
<?php
// require class file
require("customer.php");
$xmlfile = "C:/Users/Maurizio/Desktop/customers.xml";
if(!file_exists($xmlfile)) {
$doc = new DOMDocument('1.0', 'iso-8859-1');
$root = $doc->createElement('customers');
$doc->appendChild($root);
if (isset($_GET['add_customer']) && isset($_GET['new_customer_name'])
&& isset($_GET['new_customer_phone'])) {
$c = new customer($_GET['new_customer_name'],
$_GET['new_customer_phone']);
$c->addXMLCustomer($doc, $root);
}
$doc->save($xmlfile);
}
else {
$doc = new DOMDocument();
$doc->load($xmlfile);
$root = $doc->getElementsByTagName("customers");
if (isset($_GET['add_customer']) && isset($_GET['new_customer_name'])
&& isset($_GET['new_customer_phone'])) {
$c = new customer($_GET['new_customer_name'],
$_GET['new_customer_phone']);
$c->addXMLCustomer($doc, $root);
}
$doc->save($xmlfile);
}
?>
<body>
<div>
<fieldset><legend>Add new customer</legend>
<form method="get" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<label for="new_customer_name">Name:</label>
<input id="new_customer_name" name="new_customer_name" type="text" />
<label for="new_customer_phone">Phone:</label>
<input id="new_customer_phone" name="new_customer_phone" type="text" />
<button id="add_customer" name="add_customer" type="submit">Add</button>
</form>
</fieldset>
</div>
</body>
</html>
Any suggestions??
Thks
Maurizio
