Maximum number of characters in comment box?

HI all,

I'dd like to have the following, hope someone can help me out with this:

During step 1 of the checkout, customers have the possibility to add comments/instructions in the text box. I'd like to have a restriction of, let's say, 200 characters. Preferably, I'd have a "counter" above text box, which counts down from 200 to 0, as the customer types.

Is that possible?

Thanks,
Jurjen

You could hack out a copy of the html in the code which already does that, from the attributes module and implement it on your checkout page.

Partially discussed here, in reverse: http://www.zen-cart.com/forum/showthread.php?t=50075
And you'll need to copy the appropriate jscript_xxxxx.xxx file from the product page to the appropriate checkout page.

Ok, thanks. What file should I be adding the code to? Not the Templates I guess?
And this is the proper code?

 if ((ereg_replace('txt_', '', $key) == $products_options_names->fields['products_options_id'])) {
                          // use text area or input box based on setting of products_options_rows in the products_options table
                          if ( $products_options_names->fields['products_options_rows'] > 1) {
                            $tmp_html = '  <input disabled="disabled" type="text" name="remaining' . TEXT_PREFIX . $products_options_names->fields['products_options_id'] .

                            $tmp_html .= '<textarea class="attribsTextarea" name="id[' . TEXT_PREFIX . $products_options_names->fields['products_options_id'] .

                          } else {
                            $tmp_html = '<input type="text" name="id[' . TEXT_PREFIX . $products_options_names->fields['products_options_id'] .

                          }
                          $tmp_html .= $products_options_details;
                          break;
                        }
