UBB.Developers Forums UBB.threads 7 Development How Do I? putting the extra fields to work

my threads site is for kids to trade their sports, magic and other type cards with each other.

I have a forum called "Have Lists" where members post a complete list of all the cards they have. Then they usually put a link to their post in this forum within their signature (and anywhere else they can)

I figure I can simply use one of the extra fields so that members can place the url to their have list there easy enough

what i want to know how to do is:
I want to display a custom image under any member's avatar that has a URL in this extra field. The image would hyperlink to this URL

a) can this be done so that the only URL it will accept is one pointing to my forums? I dont want members using this to link to their home pages etc..)

You can use the Extra Info hack to add the Extra fields to all posts. They should already show up on their profile I think.

To only allow lihnks to your own site you could use either a small regexp checking that the link starts with you site either before showing or when saving the info.
Another way would be to only have your users enter the number of the post of their have lists in the field. Then you add the link in the templates when viewing that field.

i SWEAR i searched for this before posting.. sorry
