How can I create a coupon field? I have entered the following into the called on form process php section to no avail.
if($_POST['form']['discount'] == 'coupon')
 $_POST['form']['total'] = $_POST['form']['total'] - 5;

Any help would be greatly appreciated.

Hello,

If you are using the payment plugin available for the component, then please note that the total cost of the transaction is stored in a hidden field named 'rsfp_Total'. In order to apply a discount for this total you could try using the following code:

if($_POST == 'coupon')
$_POST = $_POST - 5;

Here is the correct code of anyone who needs it
$amount=$_POST['form']['rsfp_Total']; 
if($_POST['form']['your_coupon_field_name'] == 'your_coupon_field_code')
   $_POST['form']['rsfp_Total'] = $amount - your_amount;

this needs to be placed in "Script called on form process"

Just what I need by the sounds of it, but could you please give a step by step on how to implement the code please.

I have created a form using RSForms;
strictlyoldskool.net/index.php?option=com_rsform&formId=9

I just want to add a simple coupon field that when a user enters "#RCFF" or "Musicmondays" a 10% discount is deducted from the total amount.
I purchased RSEvents thinking that I could utilise the coupon component with the integration plugin, but this is not ideal due to having to recreate the form using RSEvents, and house if you will RSForms information in it, I wanted to do it the other way round, So a no goer on that one.

So I have put this in the "script" tags and place it directly in the bottom of my RSForm; But I am struggling to make it function. Could anyone please advise.
$amount=$_POST['form']['rsfp_Total']; 
if($_POST['form']['your_coupon_field_name'] == 'your_coupon_field_code')
   $_POST['form']['rsfp_Total'] = $amount - your_amount;


Is this right?
$amount=$_POST['form']['rsfp_Total']; 
if($_POST['form']['form[RSEProCoupon]'] == 'Musicmondays')
   $_POST['form']['rsfp_Total'] = $amount - -10%;

I cant get it to work

This doesn't need to be inserted in the form, you will have to use the specific PHP scripting area. Click Form Properties > PHP scripts and in the second textbox (Scripts called on form process), insert this:
$amount=$_POST['form']['rsfp_Total']; 
if($_POST['form']['form[RSEProCoupon]'] == 'Musicmondays')
   $_POST['form']['rsfp_Total'] = $amount - 10%;

Also, please keep in mind that your code had the "-" twice.

More information on PHP scripts can be found here:
www.rsjoomla.com/support/documentation/v...602-php-scripts.html


PS: don't use the PHP tags in the scripting areas

Hi, This works except when a user hits the submit button without filling in the required fields. I get

Parse error: syntax error, unexpected ';' in /home/root/public_html/domain.com/administrator/components/com_rsform/helpers/rsform.php(2106) : eval()'d code on line 3

Did have any luck with this code myself, used the below to work out a percentage discount (0.1 = 10%)
$amount=$_POST['form']['rsfp_Total']; 
if($_POST['form']['discount'] == 'XMAS')
   $_POST['form']['rsfp_Total'] = $amount - ($amount * 0.1);

The script provided above is an example, it should be thoroughly tested and adapted to your scenario, as an alternative you could try using a script like the one below:
if ($_POST['form']['radio'] == 'some-choice'){
  $paypal = RSFormProPayPal::getInstance();
  $paypal->args['discount_rate'] = 50;
}

I have tried all the variations shown above and cannot get this script to work. Has anyone actually got it to function at all? While it would be nice if it adjusted the total on the form I'd be happy with it adjusting the amount when going to PayPal. Here are the three scripts I've tried:

I don't get an error on the form.

But what if i need to generate a 400 unique discount codes and also to check if code was used before. Is there a possibility to do that?

Although this is a very old thread I thought I'd post the RSFormsPro solution that worked for us —just in case anyone else can use it. As you can see it's slightly different from the posted solutions:

$amount = $_POST['form']['rsfp_Total']; 
if ($_POST['form’][‘your_coupon_field_name’] == ‘your_coupon_field_code’){
  $paypal = RSFormProPayPal::getInstance();
  $paypal->args['discount_rate'] = 10;
}

Note that you need to modify it in 3 places to suit your form. The value 10 calculates a 10% discount

Just in case someone needs an update on this using an amount rather then a percentage.
dollar discount example
$amount = $_POST['form']['rsfp_Total']; 
if ($_POST['form’][‘your_coupon_field_name’] == ‘your_coupon_field_code’){
  $paypal = RSFormProPayPal::getInstance();
  $paypal->args['discount_amount'] = 10;
}

And in response to carlfarring, the three locations you change are:
"your_coupon_field_name" - create a textbox and set the name to the same as this
"your_coupon_field_code" - whatever you want your coupon code to be
"10" - what you want your discount to be

to change to a percentage
Switch
$paypal->args['discount_amount']

with
$paypal->args['discount_rate']
