Inserting multiple data into 1 field

[Samvh]

Hello, I'm trying to insert multiple data into 1 field.

 

My table is called 'members' with a couple of fields in it, One of them is friends.

So I've made a little community system where you can add a friend.

 

The problem is that I'm trying to insert the id's from the friends into 1 field.

for example: 1,2,3,4,... So later on I can select all the ID's from that field and display them.

 

At the moment I simply use: (UPDATE members SET friends='$friend_id' WHERE id='$userid').

But everytime I click on "add friend" it replaces ID's (pretty normal).

 

I heard it's possible using arrays. (I dont know alot about arrays so keep it simple  )

 

Thanks in advance

well if you want to store them as an array in one row, use serialize and unserialize

 

However I would recommend that you insert each id separately, but i'm not sure exactly how your table is set up

Thanks for the quick response.

My table is pretty basic

 

id - fullname - country - email - password - friends

 

1 - Ben Vletren - Belgium - [email protected] - 123 - 0

 

So as you can see under friends is 0. If you add a friend it should become the id of that friend (example 5), add another friend (with id 12) and it should become 5, 12 (and so one).

 

If there's a better way to do this please let me know.

You'll want another table to store the friends relationships. Storing multiple pieces of data in one field makes querying against that data rather a pain.

A simple table like? :

 

ID  -  Friend

1      2

4      6

3      4

9      5

yes something like that, more information can be added but that is the basic concept...normally using the serialization methods with databases is a pain in the butt

Oke, problem solved. Thanks for the helpful responses!
