(Help) Dropdown lists populated from database

14 years 1 month ago #13846 by GMan10
Hello,
i need help to populate two or maybe three dropdown lists from a database.
The lists should be dependant to another.

For example:

LB1 = Country
LB2 = State
LB3 = Town

If i choose a county in LB1 only the states relevant to that country should populate LB2 and after choosing a state only relevant towns should show up in LB3.

I would like this to show at registration and also be compulsory.

The documentation helped me in different areas but unfortunately for me there is nothing about connecting to a foreign database.

there have been plugins for the RC2 release which were able to open a specific table depending on what item in another table was clicked. But I never tried it and I don't know if it works with the 1.0 stable release. If it works, please let me know. I'm in need of something like that too.

It seems to be able to do just what I need. Although i'm a bit worried about adding all the data to one table.

All counties/States
All Cities/Towns/Villages
All Pubs and clubs

Would a repeated select on this table not slow the system down tremendously. I haven't tryed it yet, because it will take a while to change the standing database structure.

Please tell me what you think!

I have no intentions to make this plugin work with the advanced search. (I have nothing against it, but just don't have the time) The sites that I run do not use the advanced search, so there is no point in coding it. If someone wants to do it, I can provide some assistance though.

If you do indexing well, there is virtually no performance difference in havign the data in one or several tables.
