[Contribution] Discount Coupon Codes

Recommended Posts

@Dan Cole

 

No, I tried but it doesn't work, no search more.

 

@@Gyakutsuki Loic...if you are using the Modular Shopping Cart and would like to try this again I've worked up a module for it based on the excellent work done by Lambros @@Tsimi .   It's a bit crude yet but seems to work okay.  At this point I haven't added your fix and still have work to do to clean it up but if your interested let me know.

@Dan Cole is it possible to display your work ?

I'm developping something but not yet finish.

Good news

I am able to display the discount amount without customer session

Bad news : the total amount is not calculate.

 

Below an example on the code in execute function.


            if (isset($_POST['coupon'])) {

//verifier intégrité coupon

              if (!isset($_SESSION['coupon'])) {
                $_SESSION['coupon'] = HTML::sanitize($_POST['coupon']);
              }

//this needs to be set before the order object is created, but we must process it after
//this needs to be set before the order object is created, but we must process it after
// $coupon = osc_db_prepare_input($_POST['coupon']);
              if (isset($_SESSION['coupon'])) {
                $coupon = '';
                if (tep_not_null($_SESSION['coupon'])) {
                 $_SESSION['coupon'] = tep_db_prepare_input($_SESSION['coupon']);
               }
             }

            require_once(DIR_WS_CLASSES . 'order.php');
            $order = new order;

// discount coupons
              if (isset( $_SESSION['coupon']) && is_object($order->coupon) ) {
               $order->coupon->verify_code();
// erreur quand le nbr de coupon permis = 0 et debug = false
              }

            $form = tep_draw_form('coupon', osc_href_link('sopping_cart.php', '', 'SSL'), 'post', 'id ="coupon"onsubmit="return check_form();"', true);
            $endform = '</form>';
            $coupon = tep_draw_input_field('coupon', '', 'id="inputCoupon" class="input-sm" placeholder="' . ENTRY_DISCOUNT_COUPON . '"' );;
            $button_coupon = tep_draw_button(IMAGE_BUTTON_CONTINUE, null, null, 'secondary', null, 'sm');

            if (MODULE_ORDER_TOTAL_DISCOUNT_COUPON_STATUS == 'true') {
                // call template with $form . $coupon . $button_coupon . $endform
            }
          }
        }

@@Gyakutsuki  I have that working too ie without customer logging in but I have the same problem with the order total...when the customer logins in the total is correct but when they are not...it shows the discount but doesn't remove it from the total.   Are you using the new shopping_cart modules?

try to insert unset($_SESSION['coupon']);

 

just a litlle improve if it can help you (HTML::sanitize change by good osc 2.3.x synthax)

//verifier intégrité coupon

              if (!isset($_SESSION['coupon'])) {
                $_SESSION['coupon'] = HTML::sanitize($_POST['coupon']);
              }

//this needs to be set before the order object is created, but we must process it after
              if (isset($_SESSION['coupon'])) {
                if (osc_not_null($_SESSION['coupon'])) {
                  $_SESSION['coupon'] = HTML::sanitize($_SESSION['coupon']);

@@Gyakutsuki  Loic...here is the code I'm working with...my form is inside the module.  Try not to laugh to hard....I know just enough about coding to be dangerous....

 require('includes/application_top.php');

  if (!tep_session_is_registered('coupon')) tep_session_register('coupon');
  //this needs to be set before the order object is created, but we must process it after
  $coupon = tep_db_prepare_input($HTTP_POST_VARS['coupon']);
  
  if (tep_not_null($coupon)) {  
  
  include(DIR_WS_CLASSES . 'order.php');
    $order = new order;

   if( is_object( $order->coupon ) ) { //verify coupon
     $order->coupon->verify_code();
   }
   
    if( (!$order->coupon->is_errors()) && is_object( $order->coupon )) { //if we have passed all tests (no error message)
		$messageStack->add_session('product_action', ENTRY_DISCOUNT_COUPON_SUCCESS, 'success');
	}else{
		$messageStack->add_session('product_action', implode( ' ', $order->coupon->get_messages() ), 'warning');
	}
	
  }
  
  if (!tep_not_null($coupon)) $messageStack->add_session('product_action', ENTRY_DISCOUNT_COUPON_NO_ENTRY, 'warning');
  tep_redirect(tep_href_link('shopping_cart.php', 'SSL' ) );

With the exception of the order_total issue when not logged in....it does seem to work well.

No I didn't...it works fine when you are logged in so I figured the sort order stuff is okay...the only problem is when you're not logged in and in that case it doesn't seem to update the totals to recognize the coupon.  I'll have a look at the order total class and see if I can figure it out when I get a chance.

@Dan Cole

 

A first way, but not tested in deep with all options

 

after this in ot_discount.php

$this->output[] = array('title' => $OSCOM_Order->coupon->format_display($tax_group) . ':',
'text' => $text,
'value' => $display_type . $discount
);

add

$OSCOM_Order->info['total'] = $OSCOM_Order->info['total'] - $discount;
$OSCOM_Order->info['subtotal'] -= $discount;

in other case, it's possible to add also for conflict problem with checkout_confirmation.php

if (MODULE_SHOPPING_CART_COUPON_DISCOUNT_CONTENT_WIDTH == 'true'&& $PHP_SEL="shopping_cart.php) {
  $OSCOM_Order->info['total'] = $OSCOM_Order->info['total'] - $discount;
  $OSCOM_Order->info['subtotal'] -= $discount;
}

Let me know if it's first idea works;

@@Gyakutsuki  Loic...just added your code to ot_discount_coupon.php as follows:

     //determine if we need to display a second line to show tax no longer applied
        if( MODULE_ORDER_TOTAL_DISCOUNT_COUPON_DISPLAY_TAX == 'Display discounted tax in separate line' && is_array( $order->coupon->discount_tax ) ) {
          $discounted_tax = array_sum( $order->coupon->discount_tax );
          $text = $display_type . $currencies->format( $discounted_tax, true, $order->info['currency'], $order->info['currency_value'] );
          $this->output[] = array( 'title' => MODULE_ORDER_TOTAL_DISCOUNT_COUPON_TAX_NOT_APPLIED . ':',
                                   'text' => $text,
                                   'value' => $display_type . $discounted_tax );
        }
		// added at the suggestion of Loic
		$order->info['total'] = $order->info['total'] - $discount;
		$order->info['subtotal'] -= $discount;
		
      } else $this->enabled = false;

When I do that I get this when I'm logged in....

I lose the tax and shipping but you've given me something to think about.   I've not tried it with different coupon types yet.

I don't text with canada tax, tomorrow but work with normal tax.

 

include this adapted at your case

if (MODULE_SHOPPING_CART_COUPON_DISCOUNT_CONTENT_WIDTH == 'true'&& $PHP_SEL="shopping_cart.php) {
$OSCOM_Order->info['total'] = $OSCOM_Order->info['total'] - $discount;
$OSCOM_Order->info['subtotal'] -= $discount;

Loic I played around with this a bit more and it looks like this works...

// added at the suggestion of Loic
$order->info['total'] = $order->info['total'] - $discount;
$order->info['subtotal'] -= $discount;

when there is no user logged in with the exception of the tax....it seems to calculate the tax without taking the discount into consideration.

 

The other problem with it is that it duplicates the discount when a user is logged in....so we just need a condition to bypass your code when a user is logged in and sort out the tax issue when the user isn't.  I'm going to check now to see if there are issues when I get to the checkout confirmation page.  I'll post more once I do that.

I also have  a problem with the taxes, it diseapear ! Step by step

 

This element does'nt allow in checkout_confirmation to use this code (below)

 

This code go in ot_discount_coupon.php

$PHP_SEL = $PHP_SELF

$this->output[] = array('title' => $OSCOM_Order->coupon->format_display($tax_group) . ':',
   'text' => $text,
   'value' => $display_type . $discount
);

if (MODULE_SHOPPING_CART_COUPON_DISCOUNT_STATUS == 'true' && $PHP_SELF == 'shopping_cart.php') {
  $OSCOM_Order->info['total'] = $OSCOM_Order->info['total'] - $discount;
  $OSCOM_Order->info['subtotal'] -= $discount;
}

It doesn't seem to be an issue for me....I get the same result in checkout_confirmation as I get on the shopping_cart page.

 

So in summary....I think I just need to sort out the tax issue and then bypass that piece you added when the user is logged in.

@@Gyakutsuki  Loic I wrapped your routine in this if statement and it seems to have sorted out the duplication issue...

             // added at the suggestion of Loic
	     if ( !tep_session_is_registered('customer_id') ) {
		$order->info['total'] = $order->info['total'] - $discount;
		$order->info['subtotal'] -= $discount;
	     }

Now I just need to get the tax to calculate on the subtotal instead of the total when the user is not logged in but for now I'm off to bed.

How many clic do you need to see the result.

 

For me it's weird :

3 clics to see the discount (good coupon)

2 clics after to delete the discount (bas coupon)

                    [Unknown tax rate] => 40.8737
                )

Any idea....or can it get to it some where else?

the code included in order total calcul (module)

          $products = $OSCOM_ShoppingCart->get_products();

          for ($i=0, $n=sizeof($products); $i<$n; $i++) {
            $products_tax = Tax::getTaxRate($products[$i]['tax_class_id'], $OSCOM_Order->delivery['country_id'], $OSCOM_Order->delivery['zone_id']);
            $products_tax_description = Tax::getTaxRateDescription($products[$i]['tax_class_id'], $OSCOM_Order->delivery['country_id'], $OSCOM_Order->delivery['zone_id']);

             if ( DISPLAY_PRICE_WITH_TAX == 'true' ) {
//Modified by Strider 42 to correct the tax calculation when a customer is not logged in
              $tax_val =  (($products[$i]['final_price']/100)*$products_tax)*$products[$i]['quantity'];
            } else {
              $tax_val =  (($products[$i]['final_price']*$products_tax)/100)*$products[$i]['quantity'];
            }

            if ( !empty($OSCOM_Order->info['tax']) ) {
              $OSCOM_Order->info['tax'] += $tax_val;
            } else {
              $OSCOM_Order->info['tax'] = $tax_val;
            }

            if (!empty($OSCOM_Order->info['tax_groups']) ) {
              $OSCOM_Order->info['tax_groups']['' . $products_tax_description . ''] += $tax_val;
            } else {
              $OSCOM_Order->info['tax_groups']['' . $products_tax_description . ''] = $tax_val;
            }



// Modified by Strider 42 to correct the order total figure when shop displays prices with tax
            if ( DISPLAY_PRICE_WITH_TAX == 'true' ) {
              $OSCOM_Order->info['total'];
            } else {
              $OSCOM_Order->info['total'] += $tax_val;
            }

My module looks similar but it doesn't seem to access the actual discount coupon amount....or at least I don't see that in the above?
