Re: windows file upload = weirdness
This WebDNA talk-list message is from 2004
It keeps the original formatting.
numero = 57600
interpreted = N
texte = I think an example is in order here... Say the user uploads a file and the full-path filename comes through as "C:Documents/jim&bob.jpg" Using your code sample (without the URLs): [Text]fullfilename=[Middle StartAfter=filename="&endbefore="][name][/Middle][/Text] [listwords words=[fullfilename]&delimiters=:/\] [text]rawfilename=[word][/text] [/listwords] results in the variable [rawfilename] having a value of "jim". The reason is that the WebDNA parser encounters the ampersand between "jim" and "bob" and truncates the words parameter there, then ignores what it thinks is a parameter named "bob.jpg" (which follows the ampersand). If you add URLs to the words parameter: [listwords words=[url][fullfilename][/url]&delimiters=:/\] then the resulting [rawfilename] is the correct value "jim&bob.jpg", and your later code can strip the ampersand if desired. Note that the resulting value does not have the url'ed "%26" for the ampersand. WebDNA's parser ALWAYS does an implied [unurl] on any named parameter (one specified as "param=value") before processing its value; the [url] context is there to permit the use of characters such as ampersands and equal signs that would otherwise foul up the parameters. - brian On Apr 29, 2004, at 6:29 AM, Terry Wilson wrote: > You're right; I should have clarified that I took them out because I > have code later that strips illegals out of filenames; by URLing them, > they wouldn't get stripped, but stay in as %20 and such. > > As it happens, this wasn't the cause of her problem.
