Hi guys.
What's the 'usual' way (if there is one) of implementing an 'active' back button (which does the equivalent of the browser's back button but is implemented in CGI code)?
If, say, I'm doing a database search and come up with a list of records, each of which can be clicked on to provide the complete data for the single record, how do I get back to the page with the list of records?
Obviously I can pass all the search criteria to the detail script and have it pass them back again to repeat the search. But I know there must be a better way to do it.
Thanks for any help.
Alternatively, if James and Andrew didn't get you there, possibly because you want to nest multiple levels, I have used cookies for this purpose. For instance if you attach a discussion forum to the detail record of a search listing, then if a user goes to the detail record, then to any number of postings in the forum they will lose their search link. You could pass it around in links but I feel it is easier to throw a cookie at the user when they hit the search results, then at any point I know the last search result seen. I use the same code to set a cookie for the detail record so that cruising around the forum will also take them back to the record. Naturally these are session cookies, and I am not terribly picky about dropping (l)users that don't have cookies enabled. Mileage may vary....
