Spider diagram

[rockinaway]

Right.. say you have a question.. people can click a link that takes them to a spider diagram.. the question sits in the middle.. and then related questions link off (gathered from the database by some process of relevance).. and then more questions link of those questions (in order of relevance).. so you can see the links.. and then you can pick how many levels of questions you want to see.. and visit them like that - this is what I want to do..

 

Is this possible with PHP?

[doni49]

Sounds to me like AJAX would be better suited for that but YES I think you COULD do it with PHP.

Any basic tutorials?

It's not a subject too often covered in PHP. I agree that AJAX would make it more interactive... but it could be done with just simple links.

 

You basically want a node system, where each item has a parent node. You click the parent, and it finds all the children of that node. In that respect you can have a limitless number of levels.

 

You also need to set the starting question somewhere.

I can easily set the starting question, but has anyone got an example of a basic one they can show me?
