How do I display variables with # in them?

Hello Cf peeps.

I let users of my site create unique usernames and upload pictures. They are then able to search those items for the exact name they entered.

Today a user signed up with the name goboy#4.

How can I avoid getting a cf error when on his profile page I output <cfoutput>#username#</cfoutput> where username = goboy#4?

Thanks!

You have to escape them by adding and additional # but since it is the middle of a variable may have to write some kind of filter. For future accounts I would create a script that does not allow special characters before the account is created.

That should not have caused an error. There are places where having a reserved character in the stirng would matter. But that simple output statement should not be one of them.

Good point Ian. The one place it is happening is in the name of images. People can upload pictures and

when outputting the image path, if the name of the picture has a # in it, the image won't display.

However, the solution we reached does solve that problem.

Are you actually getting a CF error? Can you show us the message, and the offending code? From what you say in your latest post, the problem is not from CF, but that you have a hash mark in the URL for the image, which can cause problems when the browser tries to do a GET to that address to retrieve the image data.

# marks inside of a CF variable usually only cause problems if you try to do an evaluate of an expression containing that variable. Outputting the variable's contents should not cause a problem.

Ok so I'll want to search the var for a # character, if yes, set new_user = Replace("#username#","#","##","a'll")

Or something like that.

Thanks!

That should work.
