Re: eregi problem

Almost. But since this is not horseshoes nor hand grenades... Here is a trap for A/N characters: if (eregi("^[a-zA-Z0-9]+$",$GP[sifre])) { corrections to your code: Move the carat to the outside of the bracket -- I think the carat inside the bracket means negation (I think). You want a starting character anchor so that your code translates to "start with any of the following". Add the plus sign after the brackets -- means "one or more of the preceding characters" Add the $ after the + sign -- means "only the preceding character can be at the end of the line." Without the $ as an end anchor the user would be able to put non-A/N characters at the end of the line of A/N characters and your code would not trap it.
