Zone shipping - Can I disable purchase of certain items based on a shipping zone?

[Ajeh]

You could customize the code for:
/includes/modules/shipping/zones.php

and check the content in the cart and the Zone being used by changing the code:

      $this->quotes = array('id' => $this->code,
                            'module' => MODULE_SHIPPING_ZONES_TEXT_TITLE,
                            'methods' => array(array('id' => $this->code,
                                                     'title' => $shipping_method,
                                                     'cost' => $shipping_cost)));

to be:

// check cart for Zone 2
$chk_cat = 0;
$chk_cat += $_SESSION['cart']->in_cart_check('products_id','115');
$chk_cat += $_SESSION['cart']->in_cart_check('products_id','112');
echo '$dest_zone: ' . $dest_zone . ' $chk_cat: ' . $chk_cat . '<br>';
if ($dest_zone == 2 and $chk_cat > 0) {
  echo '<br>Products blocked in cart! ' . $chk_cat . '<br>';
} else {
      $this->quotes = array('id' => $this->code,
                            'module' => MODULE_SHIPPING_ZONES_TEXT_TITLE,
                            'methods' => array(array('id' => $this->code,
                                                     'title' => $shipping_method,
                                                     'cost' => $shipping_cost)));
}

      if ($this->tax_class > 0) {

Now, Zone 2 will not display if products_id 115 or 112 are in the cart ...

If you need additional Products, just add another line, with the products_id:

$chk_cat += $_SESSION['cart']->in_cart_check('products_id','XXX');

where XXX is the products_id ...

Thanks - that looks like what I'm after.
Could I set it for categories rather than product ids?

[Ajeh]

If you are using categories_id that are the master_categories_id then you can use:

$chk_cat += $_SESSION['cart']->in_cart_check('master_categories_id','XXX');

where XXX is the master_categories_id of the Products ...

Many thanks, I shall give it a try.

Hi,
We have been using Zen Cart for several years and now wish to sell into Europe. Some of our products are only available for delivery within the UK.

I have tried the code suggested by Ajeh but the error message appears at the top of the tpl_checkout_shipping page and affects the display of the header.

Would it be possible to reference the variable $chk_cat in the tpl_checkout_shipping page around line 73?

Below is an example of what I have tried to add to the tpl_checkout_shipping page but I can’t get the desired results:

<?php if ($chk_cat > 0) { ?>
<div id="checkoutShippingContentChoose" class="important"><?php echo TEXT_ZONES_PRODUCTSRESTRICTED; ?></div>
<?php } ?>

The suggested code from post #5 is working very well at restricting certain products from being delivered overseas, it is just where the error message displays which I would like to change. Any advice would be much appreciated.

A way I can see this possible is through the use of a $_SESSION variable. The echo that is identified in post 5 pushes content to the page before other processing which is somewhat what is causing the alignment problem. But, if a session variable were used, then the "error" could be stored and then on the applicable page(s) the result displayed as desired.

So at the point where the $cat_id is set to zero, add an additional line either above or below like:

unset($_SESSION['restricted_cat']);

Then where the "error" message is echoed, instead use:

$_SESSION['restricted_cat'] = {error_message};

Where {error_message} is whatever text is there currently as part of the echo. This could also be used to store "data" that is to be retrieved on the other end like an array of the product/categories, or whatever.

Then wherever it is desired to be displayed, your if statement would be:

if (isset($_SESSION['restricted_cat']) {

And you could then echo whatever you want to echo based on that condition.

Further, in this process, if the cart contents change, the message should also be updated/reflect the condition.

Just a thought.

Hi,
Many thanks for your response mc12345678. It sounds as though using a $_SESSION variable would be the best way to sort this issue out.

I have tried altering the code to include your suggestions but I always end up with the same result – the page breaks and displays nothing below the point where I have altered the code.

If you could clarify where I should be adding the additional code it would be much appreciated.

I have just made a donation to the Zen Cart team as the service and support is excellent. If you or other Zen Cart users can help me get this working I would be happy to make a donation to the individual of £50.
