To use the cartsummary.pl, you can simply add an iframe in an html page:
NOTE: You may have to change the URL for your server above.
Put the cartsummary.pl file in the cgi-bin (the same place the
quikstore.cgi file is running from) and set the permissions to 755.
That "should" display a message on the page if there are items
in the cart. If not, it simply prints " " (empty).
The message that is displayed is inside the cartsummary.pl file here:
print qq~
You have $numberofitems
$itemStr in your cart totaling:
$grand_total
~;
Just don't touch the first (print qq~) or last (~;) line.
You can add/modify/remove anything you want in the middle.
