Thanks for that help! Now I am getting an interesting error that I am not sure what to make of. Warning: REG_ERANGE in /home/httpd/www/worldvibe.org/digitall/edit_f.php on line 91 Here are lines surrounding 91: 89-> strtolower($f_loc_name); 90-> $f_loc_new = ""; 91-> $f_loc_new = ereg_replace("[^[_a-z0-9-\.]]", "", $f_loc_name); 92-> $f_loc_name = ""; 93-> $f_loc_name = $f_loc_new;

$f_loc_new = ereg_replace("[^_a-z0-9-\.]", "", $f_loc_name);

I have tried tow other variations of line 91, and both of them do not seem to work the way I am hoping for. I have (since the last message, decided to remove the offending characters, rather than replace them with an underscore (hence the ""). Below is an example of what I am trying to accomplish: Test_File#()*#$.txt should be converted to test_file.txt TEST.file.#####.txt should be converted to sean.coyle..txt I am not all that great with regular expressions, so any help I can get on this is greatly appreciated!

If not then something like this... eregi_replace() is what you are looking for.

Hey there guys, This may seem like a dumb question, but I have to ask it anyway. I have a form in one of my php based scripts that allows for file uploads. I recently noticed a potential issue if people upload files containing anything else but the standard characters ([_a-z0-9-]+(\.[_a-z0-9-]). I am not sure if this can be done, but what I need to do is parse this variable (lets call it $file_name) by character looking for anything save letters a-z (A-Z) and numbers 0-9. Any arrangements of numbers, letters and full stops (.) are to be permitted, and if any character does not meet those specifications, that single character should be converted to an underscore. Any ideas on how I can go about doing something like this? BTW: (Some background info) I examined the average validate e-mail idea, however, rather than reject the string, I would like to be able to 'replace' the offending character.
