API code for new order and client login

[techwithquestion]

Hello

 

I need to customize order page for my site. Can Some one give me code for order and client login.

 

My developer is on leave. I can not wait until he returns from leave..

 

I tried to use below code for login but its not working

 

<?php

 

$url = "http://www.domain.com/whmcs/includes/api.php"; # URL to WHMCS API file

$username = "Admin"; # Admin username goes here

$password = "whmcs_password"; # Admin password goes here

 

$command = "validatelogin";

$postfields["action"] = "validatelogin";

$postfields["email"] = "xyz@plantest.com";

$postfields["password2"] = "Zaq12345";

 

 

$data = explode(";",$data);

foreach ($data AS $temp) {

$temp = explode("=",$temp);

$results[$temp[0]] = $temp[1];

}

 

if ($results["result"]=="success") {

# Result was OK!

} else {

# An error occured

echo "The following error occured: ".$results["message"];

}

 

?>

 

Sorry I don't have much knowledge about php , did I used correct code ?
