Re: regex problem

Are you wanting the $_POST['nums1'] to have only numbers, -, ., #, : ???? Is this what you are trying to match. if so, try this. if ( preg_match("/[^0-9\#\:\.\-]/", $_POST['nums1']) ) { throw error() } This will match anything that is not a number or one of the other special chars that are in the pattern to be matched. Therefor, if it does find anything that is not in the pattern to be matched it will return true and then it will enter the if statement instead of skipping over it.

I am currently using !preg_match ('/([0-9\-\.\#:])/', $_POST['nums1'] throw error[] This fails if you use something like ' asdf ' but if you use ' asdf789 ' it passes false and does not throw an error. This is not the obvious solution.... I know its a problem in my regular expression. Should I ONLY be using ' /([0-9])/ ' , ? Thanks in advance. Daniel
