Hey,
Thought i'd post some code.
It's not a big piece of code, but very useful.
In some scripts, it's annoying when you are editing a MySql (For Example) Entry, and it has some dropdown menu's, lets say,
Forum Leader
-- Adrian
-- Hitch
-- xD
-- Jake
Right, so, when we edit that form, we sometimes get the Dropdown List in that order ^, though, what if we have already assigned Hitch to that forum, and we are editing the Forum Name.
Everytime we click submit, we are gonna have to check if the FL dropdown is set the user we want.
It can get very annoying, anyway, this will automatically select the current FL as the Default option...
Ok, that may have being a bit hard to understand? ^
Anyway, here's the code.
When i use terms such as user, it's meant as a example.
So, list all the users, and set the current FL as default, according to the Forum Table.
Lets say, your Dropdown Option's arn't stored in the Database.
So, you have 4 options, and you want to Pre-Populate them?
Do the following,
It's just a little thing to make your applications more user friendly.
I made a quick function for the Static Dropdown Menu's.
Use
Hope it helps some of you, like i said, it's not a huge thing, but it deffinately makes your applications better.
Don't forget about the little things.
Oh, and i don't want any moaning about the queries, they were just examples, so no "Why not use JOINS?" :hehe:
