file name length script

[@Js1212]

We have recently changed our server situation and was informed that we now must limit file names to 31 characters or less and no spaces or special characters allowed.

I already have a script that i have all my designeres run when a file is finalized that i would like to incorporate this feature into. Does anybody have an existing script or snippet that will throw an alert if these conditions exist?

If your filename matches the follwing regex it is good

^[a-zA-Z0-9\.]{1,31}$

A sample code for this would be

var f = File("/Users/manan/Desktop/test.zip")
var fName = f.name
if(fName.match(/^[a-zA-Z0-9\.]{1,31}$/))
	alert("Allright")
else
	alert("Error")

Thank you....I added an underscore to the acceptable list of characters (my designers like underscores) and it is working great!!!!!

[@Js1212]

I marked it as correct because it works great but.....If i could ask for one more little bit of help?

how would i eliminate the alert ("alright")?

I only want an alert if there is more than 31 but just pass thru if less than 31

In that case change the code to the following

var f = File("/Users/manan/Desktop/test.zip")
var fName = f.name
if(!fName.match(/^[a-zA-Z0-9\.]{1,31}$/))
	alert("Error")
