    Now I didn't find anything in the searches; so, posting a new thread.

    I have data fields where users can enter anything. I would like to strip out characters that aren't a number, or a letter(a-z, and A-Z). I think it's a simple solution, if I pass the right parameters to replace_str(), but I have not found it.

    Anyone know a simple solution?

    thanks,

    tom

    I think this should work... 
    preg_replace ("#[^a-z0-9]#i", '', $field);

    WOO HOO!

    Thank you very much Shawn! Worked like a charm. Funny how once you are shown the solution, how easy it looks. :)

    Thanks,
