Warning:preg_match error (class.upload.php)

Question

Verot upload class (class.upload.php v3.2) gives an eror while upload and mime check.

if (preg_match("/^([\.-\w]+)\/([\.-\w]+)(.*)$/i", $this->file_src_mime)) {
                            $this->file_src_mime = preg_replace("/^([\.-\w]+)\/([\.-\w]+)(.*)$/i", '$1/$2', $this->file_src_mime);
                            $this->log .= '-&nbsp;MIME validated as ' . $this->file_src_mime . '<br />';
                        } else {
                            $this->file_src_mime = null;
}

This occurs an error:

Warning: preg_match() [function.preg-match]: Compilation failed: invalid range in character class at offset 7 in class.upload.php on line 2616

Thanks for suggestions.

- should be escaped too - \- Or put in the end of block [\.\w-] — u_mulder

[\.-\w] is illegal because \w is a character class, not a character. As written, your regex is looking for characters in the range . to \w, which makes no sense.

It's not clear to me what you are trying to do, but you can't do this.

I think you may want ., -, or word characters (anything matched by \w), in which case you should use [.\-\w].
