I'm not a PHP guy, but I've been doing a number of HTTP_Post calls with the Base Elements plugin to return a web page or other information from servers in the cloud. This works great when I know the format of what to post, including the headers.
I have a client with a web page that has a PHP login. I can read the PHP and see it is doing a post to login. Knowing the PHP code, is there a way to format an HTTP_Post URL to automaticaly log into this web page using User IDs and passwords stored in FileMaker?
