I am completely new to filemaker, I've been using it for about a week... so please forgive my ignorance. This is my situation... I have a database on a server made with filemaker server advanced 10. I have a html based website with a SSL subdomain which I linked to the database on my server. I need to know what I need to do in order to have a php login from my website to allow users access to the database. Hopefully someone out there can help me out. Thanks
