Re: [WebDNA] listfiles problem
2011
It keeps the original formatting.
interpreted = N
texte = --Apple-Mail-16--361969960 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=us-ascii What WebDNA "should" do is far less important than what WebDNA "does" = do, and WebDNA does return an error if the specified file name is not = found. Try this as a way to handle this error message: [text]tFileList=3D [listfiles path=3Dimages&name=3D-[serialno].jpg&exact=3DF]

Try this as a way to handle this error = message:
[text]tFileList=3D = [listfiles path=3Dimages&name=3D-[serialno].jpg&exact=3DF] = <img src=3D"images/[filename]"> = [/listfiles] [/text] [if "[url][tFileList][/url]"^"FileNotFound"][then] = No files found for serial number [serialno]<br> [/then][else] = [tFileList] [/else][/if]

Hi
I have a folder of images that are named in = the format...
random_names-XXX.jpg
Where XXX is a serial = number for a record in a database
I don't know what the = 'random_names' bit is but it doesn't contain anything other than letters = an underscores. The filename always ends in hyphen serial number = .jpg
When I pull a record from the database I want to do a = listfiles on the image folder and see if one of them ends in the serial = number.
Using...
[listfiles = path=3Dimages&name=3D-[serialno].jpg&exact=3Df]
<img = src=3D"images/[filename]">
[/listfiles]
...works fine when = I have a matching image but I get an error message if there is no = matching image file like...
An unknown error = occurred:
FileNotFound
-30.jpg
I've tried hiding the = listfiles inside a showif with another listfiles but it doesn't work, = the error still shows...
[showif [listfiles = path=3Dimages&name=3D-[serialno].jpg&exact=3Df][isfile][/listfiles= ]=3DT]
= [listfiles = path=3Dimages&name=3D-[serialno].jpg&exact=3Df]
<img = src=3D"images/[filename]">
= [/listfiles]
[/showif]
...I'm on WebDNA 6.0a on Mac OS = X Server 10.4.11
What am I doing wrong here? Shouldn't = [listfiles] just show nothing is it doesn't find a = match?
