Re: Define constants: awkward usage?

Hi all,

    I got this sets(20) of defined constants which using them as keys to an

array

    eg
    define("FNAME", "fname");
    farray = array( FNAME => "hello" ,...);

    my question is how do I insert that directly into a javascript(to do

some client validation)

    I need this:
    var fname = document.addrform.fname.value

    var fname = document.addrform.{FName}.value        //don't work
    var fname = document.addrform.{'FName'}.value        //don't work
    var fname = document.addrform.[FName].value        //don't work

    I know this work, but messey
    $tmp = FNAME;
    var fname = document.addrform.{$tmp}.value

you could try sprintf()/printf(): $output = sprintf('var fname = document.addrform.%s.value', FNAME ); or printf('var fname = document.addrform.%s.value', FNAME );

    I'am finding the use of define constants rather awkward. does anyone

make much use of them?

yes. :-) for... session varnames post/get varnames bitwise flags er...?

Thanks Tony
