It is very common for users of WHMCS to want to link to WHMCS from their website. This can be in the form of an order link, or with a form that either takes the user straight to the domain checking process to check the availability of the domain they want or to login.

With WHMCS, this is made easy as all the code you need is provided to you customised and ready to insert into your website by simply going to Utilities > Integration Code.

Order Links

You can obtain direct order links for products from the product configuration screen. A direct order link takes the user straight into step two of the order process with the product or service preselected. This is used for order links on your site for specific products. The link looks something like this:

http://demo.whmcs.com/cart.php?a=add&pid=1

To link to the order process with a given product and annual billing cycle preselected, you can use a link like this:

http://demo.whmcs.com/cart.php?a=add&pid=1&billingcycle=annually

To link to the order process with a domain preselected, you can use a link like this:

http://demo.whmcs.com/cart.php?sld=google&tld=.com

To automatically apply a promotion code to the order, you can append &promocode=xxxx to any of the cart links, but on it's own the link would look like this:

http://demo.whmcs.com/cart.php?promocode=xxxxxxx

You can also link directly to an individual product group like this where the gid is the ID of the group to show:

http://demo.whmcs.com/cart.php?gid=1

To link to the cart and specify a specific order form template to use, the link would be like this where boxes is the template to display:

http://demo.whmcs.com/cart.php?carttpl=boxes

There are many further options you can use, such as your own configurable options. The simplest way of formulating a url is to step through the order process as normal to the product configuration step, then right click > view source and get the field names and value IDS. These can then be used in your direct link URLs.

Setting the Language/Template via the URL

You can set the language or template to be displayed to the user with the link you use to WHMCS. This is done with links such as:

http://demo.whmcs.com/index.php?systpl=portal

http://demo.whmcs.com/index.php?language=Spanish

http://demo.whmcs.com/index.php?systpl=portal&language=Spanish

http://demo.whmcs.com/cart.php?systpl=portal&language=English&gid=1

http://demo.whmcs.com/cart.php?systpl=portal&language=Spanish&a=add&pid=1

These can be combined, used on any page and used with the direct order links

Specifying Currency in a link

You can link to the order form with a specific currency by simulating what the form shown for currency selection does:

http://demo.whmcs.com/index.php?cart.php?currency=1

http://demo.whmcs.com/index.php?cart.php?currency=1&language=Spanish

Support Ticket Links

You can link to the create ticket page with a number of predefined settings. All of which are interchangeable:

To define the support department, client name and email address you can use a link like this:

http://demo.whmcs.com/submitticket.php?step=2&deptid=1&name=Jeff&email=jeff@example.com

To define the ticket subject and message, use a link like this:

 http://demo.whmcs.com/submitticket.php?step=2&subject=Questions&message=Your_message_here

Showing Announcements on your Site

You can display the announcements on any page of your site using the code below. This will display the latest 3 announcements set to published status.

<?php
include("support/dbconnect.php");
include("support/includes/functions.php");
$query = "SELECT * FROM tblannouncements WHERE published='on' ORDER BY date DESC LIMIT 0,3"; 
$result = mysql_query($query);
while ($data = mysql_fetch_array($result)) {
 $id = $data["id"];
 $date = $data["date"];
 $title = $data["title"];
 $announcement = $data["announcement"];
 $date = fromMySQLDate($date);
  echo("<p><font color=#cccccc>$date</font> - <b>$title</b><br>$announcement</p>");
}
?>

You should replace the word support in the first two lines where it includes files from the WHMCS folder with the path to your WHMCS directory.

Showing The Login Form on your Site

You can display the login form on any page of your site using the code below. This will display the required login form to login to the WHMCS Client Area.

<form method="post" action="http://www.yourdomain.com/whmcs/dologin.php">
Email Address: <input type="text" name="username" size="50">
Password: <input type="password" name="password" size="20">
<input type="submit" value="Login">
</form> 

You should replace the URL of the form action to the path to your WHMCS directory.
