This string gets processed and some mathmatical cals done to them, then the results are returned to the same page via cf div and bind attribute. Everything works if only numbers are entered.

Re: User form input sanitization 12 Years Ago by arrgh What is the error message?

[Enable debugging by adding 'cfdebug' to your URL parameters to see more information] Is the error I'm getting. Re: User form input sanitization 12 Years Ago by arrgh *Enable debugging by adding 'cfdebug' to your URL parameters to see more information* And when you did what it said, what was the real error message? Note, ajax debugging has to be enabled in the CF Admin too. > `<cfset actualVolts = url.socketVoltage>` A couple observations - you're only validating the 1st parameter, not all of them.… Re: User form input sanitization 12 Years Ago by teedoff Well I only added the first to test. When I added the first, it seems a syntax error is present because the color of all following code changed, which usually indicates a missing quote or comma or something. I'll check the ajaz debug info this evening when I get home. Thanks for the help. Re: User form input sanitization 12 Years Ago by arrgh Oh well you are missing a closing single quote. I thought it was just a pasting error. `<cfset lampVolts = REReplaceNoCase(url.lampVoltage, '[^a-z0-9]', '(missing here), 'all')>` But you should use the debugger too. That's where all the juicy error messages are when using ajax features ;-) Re: User form input sanitization 12 Years Ago by teedoff Ok that missing single quote fixes that problem. Maybe I should have explained my desired results better lol. What I'm wanting to do is strip anything BUT numbers from the input fields. Then if a user types in 120v, or 120volts, all characters except the numbers are stripped out before processing. Hope that makes better sense. Re: User form input sanitization 12 Years Ago by arrgh Yeah, that's what I figured. But you'll still need additional validation to handle common math errors (divide by zero, value is completely non-numeric, etc..) Re: User form input sanitization 12 Years Ago by teedoff This seems to work fine: > <cfset lampVolts = REReplaceNoCase (url.lampVoltage, '[^0-9]', '', 'all')> > <cfset actualVolts = REReplaceNoCase (url.socketVoltage, '[^0-9]', '', 'all')> >  > <cfset lumens = 27500> > <cfset life = 500> >… Re: User form input sanitization 12 Years Ago by arrgh > Not sure what you mean about divide by zero values. You're using the variables in a division operation. Dividing by zero throws an error. If the final value is 0 the code will blow up. Likewise, if the result of your regex is an empty string, like if the user entered nothing or all letters. Re: User form input sanitization 12 Years Ago by teedoff lol Never thought someone might enter a 0 as a value. hmm ok need to do something different then. Thanks! Re: User form input sanitization 12 Years Ago by teedoff Well I'm trying to find some help on this, but everything I find discusses SQL division by zero errors. Not sure that's what I need since this is just a user input variable. Know any good links for this? Thanks. Re: User form input sanitization 12 Years Ago by arrgh Handling is basically the same in any language. Use an if/else to do the division when the value isn't 0. Otherwise, do something else like return 0. Re: User form input sanitization 11 Years Ago by simplico Ever thought to use <cfinput validate="numeric" ...>? Re: User form input sanitization 11 Years Ago by arrgh That would certainly improve the UX. But like always, you've still got to back it up with server side validation.
