A Code about PHP how to build a genealogy tree

Hi Hylon,

You can try the following approach:

At first you need to make a single table like the following:

Id

Name

Parent

Parent needs to have the id of the user. For example, a parent with 0 has no parent and a parent with some ID means it is connected to another parent.

If you want to take it further, say you want to show the husband/wife of a person, then you can try the following:

Id

Name

Parent => parent:0 = no parent; parent:-1 = married to someone in the family

Married_to => married_to: 0 = single, no children; married_to: xx (userid) = married to someone

Hope this helps.

Thanks.
