Show all / view all on new product pages

I have done the show all for the product pages but doing one for the new product pages is quite different since all categories are represented.

Here's the code for the product pages:

 if (($_GET['override'] == 'more') && (!$_GET['cPath'])) {
    // Split pages or comment out to not show link when already showing all
    echo 'path '. $_GET['cPath'];
	
	 ($listing_split->number_of_rows > MAX_DISPLAY_PRODUCTS_LISTING ? '<a href="' . zen_href_link(FILENAME_DEFAULT, 'cPath=' . $_GET['cPath']) . '">' . PRODUCT_LISTINGS_SHOW_SPLIT_PAGES_PRODUCTS . '</a>' : '');
  } else 
// only show link if more than one page
	  if ($_GET['cPath'] != ''){
    
	//show all link
    echo ($listing_split->number_of_rows > MAX_DISPLAY_PRODUCTS_LISTING ? '<a href="' . zen_href_link(FILENAME_DEFAULT, 'cPath=' . $_GET['cPath'] . '&override=more') . '">' . PRODUCT_LISTINGS_SHOW_ALL_PRODUCTS . '</a>' : '');
  }

(in case anyone is interested) place that in a div to float right after ```php
if ( ($listing_split->number_of_rows > 0) && ( (PREV_NEXT_BAR_LOCATION == '1') || (PREV_NEXT_BAR_LOCATION == '3') ) ) {

So no cPath in the new products.

What I've got so far is ```php
if ($_GET['override'] == 'more') {
    // Split pages or comment out to not show link when already showing all
      //how to show all?
	MAX_DISPLAY_PAGE_LINKS == $products_new_split->display_count(TEXT_DISPLAY_NUMBER_OF_PRODUCTS_NEW);
  } else 
	  if ($products_new_split->number_of_rows > 0){
    // only show link if more than one page
	
    echo ($products_new_split->number_of_rows > MAX_DISPLAY_PRODUCTS_LISTING ? '<a href="' . zen_href_link(FILENAME_PRODUCTS_NEW,  '&override=more') . '">' . PRODUCT_LISTINGS_SHOW_ALL_PRODUCTS . '</a>' : '');
  }

That doesn't change a thing. Good guess - but no dice. So how do I override the MAX_DISPLAY_PAGE_LINKS in this line to show all?

$products_new_split->display_links(MAX_DISPLAY_PAGE_LINKS, zen_get_all_get_params(array('page', 'info', 'x', 'y', 'main_page')));
