Attribute values lost on redirect

[Dave224]

I have a custom form that comes up when "add to cart " on a product info page is clicked. The product info page has several attributes with default values that come up when the product info page first comes up. If the customer forgets to select a value for an attribute option, I want to display an error message and bring the product info page back up, with the attribute values set to the previous values, so the customer doesn't have to start over. In addition, I want this to happen before the custom form is displayed. I have the error message and redirect back to the product info page working, but the option values displayed are the default values, not the previously chosen values.

How can I redirect back to the product info page from an extra cart action file with the selected option values shown?

Thanks for any suggestions.

Basically need to capture the information that was originally posted, could then store it in a session value or if on this extra page there is a submit button there also, then the posted data could be again stored as post data that can then be processed again. Otherwise would capture the posted data as session data that then could be turned into posted data to be processed by includes/modules/YOUR_TEMPLATE/attributes.php. There is code there that re-selects the options previously chosen when the data is again available for processing.

Take a look at code sections such as:

                      if (!empty($_POST['id']) && is_array($_POST['id'])) {
                        $selected_attribute= false;
                        foreach ($_POST['id'] as $key => $value) {
                          if (($key == $products_options_names->fields['products_options_id'] and $value == $products_options->fields['products_options_values_id'])) {
                            // zen_get_products_name($_POST['products_id']) .
                            $selected_attribute = true;
                            break;
                          }
                        }
                      } else {

I have saved $_POST in $_SESSION just before the redirect back to the product info page in the extra cart actions file. $_POST is restored at the start of the file the next time through. But no joy.

It needs to be "restored" prior to includes/modules/YOUR_TEMPLATE/attributes.php is executed. This may be best supported as part of the includes/modules/pages/YOUR_PAGE load process either using an observer or adding an additional file for variables or the like...
