Two questions

[sean69]

How can I call a function name dynamically?
i.e. I have a bunch of validation functions that I need to call dynamically. - any thoughts?

AND... is there a method of telling coldfusion to include all files in a particular directory (without the song and dance of listing the directory, looping through the list etc.. )

answer 1 - use evaluate

answer 2 - proably not, but you could always try to use a wildcard. Or, you could write a master include that contains all the other cfincludes. This would allow you to specify the order in which the files run.

Hi Dan;

Would you please "elaborate" on the "evaluate" <grin>

I've looked at that function several times, but for some reason or another it's correct use seems to evade me.

Q2... yea wild cards don't work Ho-well

got it..

#Evaluate(FunToRun&"(RunAgainst)")#

wish I understood it completely though.... thanks for the pointing of the right direction.

As a last resort, maybe.

// some basic functions
function f(){
return true;
}

function g(){
return false;
}

// now use a static name, fnToCall, to dynamically call different functions
fnToCall = f; // "f" being the function we defined above
writeOutput(fnToCall()); // outputs "true";

fToCall = g;
writeOutput(fnToCall()); // now outputs "false";

Functions can be assigned to variables just like any other value / variable
/ object.


> answer 2 - proably not,

Just "no, you can't". You need the song and dance. But if it's the sort
of thing you're doing on a regular basis (can't think why you would be, to
be honest), then you should write a UDF that does it, and the you only have
to sing and dance once. Thereafter: use the UDF.
