Understand Blog's code
Anyone can explain me how the blog's select data of a DB. It seems they use some variables ... but how?? I need a similar solution for a site.
That's an incredibly vague question, even if you were to specify a particular blog system.
Basically, they search the database for results that match a certain condition, such as being part of a discussion, from a user, from a certain date, or matching a certain ID.
Though the systems are complex, the basic concepts are quite simple from which they are built.
Take a look here, and go through the tutorials, and that should explain most of this:
