Seems like this topic comes up regularly.
I'd really like to go directly to a record with a unique key that is passed in the URL. Like in my Stock_Records database I'd like to be able to pass a URL (from my main company web site) so that customers can check our stock levels directly from our Fielmaker solution. But because I can't pass the stock code in the URL, the customer would have to remember and retype the stock code, so it doesn't really work. I have to use a full Custom Filemaker PHP solution.
Shame, I hope FM implement more 'scraping' in the future.
