How can I show voucher information in any .tpl file

[Nickovitshj]

Hi there,

What I want to achieve:
I want my voucher information to be showed on any .tpl file. For example on a product.tpl file, or on the homepage of my store.

From what I understand the cart rule logic is to be found in:
/controllers/front/DiscountController.php

And if I want to make it accessible anywhere I should add it to the array found in the following function:
protected function assignGeneralPurposeVariables()
In file:
/classes/controller/FrontController.php

Basically I want to put the contect from the discount.tpl file in other .tpl files:
/themes/classic/templates/customer/discount.tpl

However, I find myself not being able to manage this.
Is there anyone with more experience in this who can help me with this?
 

PS version: 1.7.6.5

I have now added the following variable to the following code:
protected function assignGeneralPurposeVariables()
In file:
/classes/controller/FrontController.php

 

Added code:
 

'cart_ruleseverywhere4' => CartRule::getCustomerCartRules(
                $this->context->language->id,
                (isset($this->context->customer->id) ? $this->context->customer->id : 0), 
                true, 
                true, 
                true,
                $this->context->cart),

The result is that I'm now only getting the CODE, DESCRIPTION AND QUANTITY.
But I need the other fields as well, which are:
Value, Minimum, Cumulative, Expiration date

However, these are not showing....

Solution found:

The code that I had added above is good to use.
It seems that in my .tpl file my foreach loop that I had copied from discount.tpl could not be used in my new .tpl file.

I had to change the following:
{$cart_rule.value} to {$cart_rule.reduction_amount}
{$cart_rule.voucher_date} to {$cart_rule.date_to}

Original code:

{if $cart_ruleseverywhere4}
        <table class="table table-striped table-bordered hidden-sm-down">
          <thead class="thead-default">
            <tr>
              <th>{l s='Code' d='Shop.Theme.Checkout'}</th>
              <th>{l s='Description' d='Shop.Theme.Checkout'}</th>
              <th>{l s='Quantity' d='Shop.Theme.Checkout'}</th>
              <th>{l s='Value' d='Shop.Theme.Checkout'}</th>
              <th>{l s='Expiration date' d='Shop.Theme.Checkout'}</th>
            </tr>
          </thead>
          
                {foreach from=$cart_ruleseverywhere4 item=cart_rule}
                <table class="table table-striped table-bordered hidden-sm-down">
                <tbody>
                  <tr>
                    <th scope="row">{$cart_rule.code}</th>
                    <td>{$cart_rule.name}</td>
                    <td class="text-xs-right">{$cart_rule.quantity_for_user}</td>
                    <td>{$cart_rule.amount} (Tax Incl.)</td>
                    <td>{$cart_rule.voucher_date}</td>
                  </tr>
                {/foreach}
              </tbody>
              </table>
          {/if}

Edited code:

{if $cart_ruleseverywhere4}
        <table class="table table-striped table-bordered hidden-sm-down">
          <thead class="thead-default">
            <tr>
              <th>{l s='Code' d='Shop.Theme.Checkout'}</th>
              <th>{l s='Description' d='Shop.Theme.Checkout'}</th>
              <th>{l s='Quantity' d='Shop.Theme.Checkout'}</th>
              <th>{l s='Value' d='Shop.Theme.Checkout'}</th>
              <th>{l s='Expiration date' d='Shop.Theme.Checkout'}</th>
            </tr>
          </thead>
          
                {foreach from=$cart_ruleseverywhere4 item=cart_rule}
                <table class="table table-striped table-bordered hidden-sm-down">
                <tbody>
                  <tr>
                    <th scope="row">{$cart_rule.code}</th>
                    <td>{$cart_rule.name}</td>
                    <td class="text-xs-right">{$cart_rule.quantity_for_user}</td>
                    <td>{$cart_rule.reduction_amount} (Tax Incl.)</td>
                    <td>{$cart_rule.date_to}</td>
                  </tr>
                {/foreach}
              </tbody>
              </table>
          {/if}

Hope this helps people in the future

If anyone has any idea, as to how I can make a sum of the {$cart_rule.reduction_amount} values, I'd love to hear that.
I'd like to show that as well in my .tpl file.

In the meantime I have found a solution for my question above.
The current result can be found in the image I uploaded.

Now I want to show information for the category restrictions that are being set for these vouchers.
However, currently the only information I can get is a 1 or a 0.

{if $cart_rule.product_restriction == 0}Voucher can be used for all products{/if}
But when my $cart_rule.product_restriction == 1 I should be able to list the category or multiple categories that this cart rule has been restricted to.

However, currently I'm clueless as to how I can achieve this. I tried looking up how to possibly achieve this through an SQL query.
But the tables that are used for this are so incredibly unclear. Result is that I can't even find the category name or id's being linked to these cart rules.

Thanks in advance,
Nick
