Hi again,

Need some advice here.. I got 2 drop down list.
Whenever I select the first drop down it will only show certain item in the 2nd drop down list.

Eg:
1 drop down = A (Initially, it contain A,B till Z but let say we select A)
2 drop down = A.a, A.b, A.c until A.z

more eg..
1 drop down = C (Initially, it contain A,B till Z but let say we select C)
2 drop down = C.a, C.b, C.c until C.z

Anyone know where I can get some online tutorial/example to do these kind of coding in PHP?

Cheers!

I can provide the theory...

for dropdown 1 lets say you select "A"...you need to use onChange(this->submit()) to $_SERVER['PHP_SELF']

now you have acces to the value "A" to populate the 2nd drop down.

Rather than using PHP, it will be better if you use PHP to build javascript function to create arrays of items for each selectbox, i.e data_1=new Option('direction','');data_2=new Option('sex','');data_1_1('right',0); data_1_2=new Option('left',1);data_2_1=new Option('female',1);data_2_1=new Option('male',0), etc.
Then, another function to work with 'onChange' to handle selectbox1 change.

You could go the easy route and use something like Dynamic Drive's "Chained Select List" script:

Dynamic Drive DHTML Scripts- Chained Select Menu

Or the one from DHTMLGoodies:

Chained select boxes

Or Matt Kruse's Dynamic Option Lists script:

Dynamic Option Lists from JavascriptToolbox.com

IMO the best idea.
