insert database nusoap-complexType - php

Question

I want to create insert database a web service from :
http://www.discorganized.com/php/a-complete-nusoap-and-flex-example-part-1-the-nusoap-server/
Here's my script :
<?php
require_once 'lib/nusoap.php';
$client= new nusoap_client("http://127.0.0.1/test2/index.php", false);
$in_contact=array ('first_name'=>$_POST['first_name'],
'last_name' => $_POST['last_name'],
'email' => $_POST['email'],
'phone_number' => $_POST['phone_number'],);
$result = $client->call('insertContact', $in_contact);
if ($result){
echo "OK";
} else {
echo "Error";
}
?>
despite increasing ID, why the other columns remain empty ?
please help me, thank you.
The <form> code..
< form action="Contact.class.php" method="GET" > Nama Depan:<br> <input type="text" name="first_name"/><br> Nama Belakang:<br> <input type="text" name="last_name"/><br> Email:<br> <input type="text" name="email"/><br> Telepon:<br> <input type="text" name="phone_number"/><br><br> <input type="submit" value="Submit"/><br> < /form >

Answer 1

As you can see the method is GET , Change that to POST
Like this...
<form action="Contact.class.php" method="POST" >
The fixed <form> code.. You had a lot of indentations gone wrong..
<form action="Contact.class.php" method="POST" >
Nama Depan:<br> <input type="text" name="first_name"/><br>
Nama Belakang:<br> <input type="text" name="last_name"/><br>
Email:<br> <input type="text" name="email"/><br>
Telepon:<br> <input type="text" name="phone_number"/><br><br>
<input type="submit" value="Submit"/><br> </form>
