For instance, I have viewpost.php and it’s set up as needed and I only need to change the content within divs in there.
For example, I’m going to have to do viewpost.php?id=1,2,3 etc. But should I do EVERYTHING off index.php using index.php?action=viewpost&id=1?
Then also, do I use if statements, or do I communicate with my database using those get requests?
Overall, I plan to use modrewrite anyway, but I am clueless on the proper way to set up loading multiple pages off one, or a few php files.
I have a template and I just need to fill it using database data.
Easiest way is something very basic like this (Not very secure though)
A better solution is to use something like http://www.smarty.net/ to handle templating and content loading. Slightly more complicated, but most likely worth the extra effort if you’re doing anything beyond a very simple website.
