File Name Format

I have a coldfusion app that allows users to upload images.
The problem is that many of these users are not web savvy and
upload hte wrong types of images with terrible names. I have error
handling in place but would love to be able to disallow uploading
of certian types of files from within the cffile dialogue. Like
only allow jpegs.
More importantly I am looking for a good name formatting
function that will strip out all the bad characters and spaces and
truncate the name and make sure they end with the proper extention.
Is there something out there that could do this? Thanks.
Eric

You don't need to write any javascript.
CFinput takes care of all of this for you...
<CFINPUT type="file" name="FileValid"
validate="regular_expression"
message="Enter a valid image file or else."
pattern="[a-zA-Z0-9_:\\]+\.(jpg|png|gif|JPG|PNG|GIF)"
validateat="onblur,onsubmit"

  • Custom File Name Format in B2B Console

    Hi,
    Please let me know if we can have a customized File Name Format in the B2B Console for the X12 EDI/XML Files.
    I have read the Oracle doc and only the following formats are mentioned:
    %FROM_PARTY%
    %TO_PARTY%
    %DOCTYPE_NAME%
    %DOCTYPE_REVISION%
    %MSG_ID%
    %TIMESTAMP%
    Is there a way to have a PO# (From the Trading Partner Payload) in the filename format?
    You help is appreciated.
    Thanks
    Priyanka G

    no. It has the format which helps B2B in identifying the agreement

  • Rename file name & format using ftp sender

    Hi all,
    This is regarding the renaming of file at sender file(FTP) communication channel and placeing the same file in the same folder.
    At FTP server at sender side (i.e.clients place) is in .txt format.But now .txt file has to rename and change into .sav foramt with below required name convention of file.
    client format is  :  SAP_Order.txt (Pervious file name).
    We need to change the file in to "SAP_Order_yyyymmddThhmmss.sav" format..
    How can i achieve this requirement?
    Can please suggests me solutions ASAP.
    Best Regards,
    satya,

    Hi,
       if your requirement is to pick the  existing file in the FTP folder...and send as idoc to the target and place the renamed file to FTP folder...
    then its simple...
    use two receivers instead of one , one for point to target and other for sender itself... (second receiver  is for  changing  the file name format....)
    Hope the above understanding is correct...if not provide more details of your requirement...

  • File name format of rotated access log

    Hi,
    I'm using wls5.1sp9 on Solaris.
    Is it possible to specify a different file name format of the rotated http access
    logs?
    Instead of getting files named access.log0001 and so on, I would prefer access.log.<date>
    or some other custom format.
    Best regards,
    Torleif Galteland

    Hi,
    Thanks for your response. But I have another query. The name of the file as per your reply is like UsageReport.xls correct? Now my query is, should it contain some date,account id/orgid etc associated for that usage. The reason for my query is that if MSP
    downloads the usage for different orgs having same bill date then it would conflict with the different usage files.
    Thanks And Regards,

  • IPhoto: After I've changed the file name/format in Finder iPhoto can't load/relink to the referenced file.

    After I've changed the file name/format in Finder iPhoto can't load/relink to the referenced file anymore. For some reasons I don't like to reimport the file.

    Hmm the advice has been not to use referenced libraries - you ignored and did it anyway and you find the advise not helpful
    Furthermore the advice is that if you choose to use a referenced library that you assure that the path never changes - you also choose to ignore that advice and do it anyway - and you blame the peopson trying to help you
    once again - you have one choice - change the file names back and put the files back in the exact same place - and again you are totally ignoring the advice and instead name calling and attacking the person giving you advice
    Maybe life would be easier if you followed advice rather than ignoring it and then complaining that things no longer work
    change the name back and you will be fine until the next problem you hit that is caused by choosing a referenced library
    Have a nice day

  • Run Applet On Server Using 8.3 File Name Format

    Hello Everyone,
    I am currently trying to produce an applet that will display content from a PLC (which hosts its own webpage).The PLC itself only allows files using the 8.3 file name format to be stored on it (eg. 123456789.123).
    I have tried a few simple things, such as changing the ".class" file extension to ".cls". But this just produced an error in my internet browser (IE 8).
    Any help and/or work-arounds would be greatly appreciated.
    Thank you,

    Hi,
    This is the UDF u have to write in Mapping,
    DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
    DynamicConfigurationKey key =
    DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
    String ourSourceFileName = conf.get(key);
    return  ourSourceFileName;
    Using this u will get the File name into target side,In this UDF add the Time stamp.

    Then what configuration changes we need to make , So that the listening channel delivers these files to GREEK_To_LATIN agreement.
    in simple words, Can we read files which does not contain FROM_TP as starting string in their file names.?

  • 8.3 file name format

    Hello
    I need to execute a dos program from java application. I want to use the following sentence:
    Runtime.getRuntime().exec("cmd.exe /c start " + mySentence);
    My problem is I need path and file names in 8.3 format (by example Program Files -> Progra~1).
    My question is: �How can I to obtain this short name for path and filename?
    Many thanks for your help

    If you really want the 8.3 path, you'll need to use JNI - take a look at the GetShortPathName() Win32 API call.
    However, for what you are trying to do, I think all you need to do is put quotes around the path you are trying to execute - i.e.:
    Runtime.getRuntime().exec("cmd.exe /c start \"" + mySentence + "\"");
    <RANT>Why MS decided that it's OK to have spaces in a path/filename is just beyond me... it adds very little to the user experience and makes parsing the darned things almost impossible...</RANT> :-)

  • The file name format for Voice Memos has changed - how can I change it to the original format?

    The file names for the voice memos changed in the last update.  Now the day is first, which means when you sort them in a file folder, they sort by the number of the day and not year - month - day as before.  Is there a way to change it back?

    Restore it as new or sign out of that account and into yours.  Both are covered in the manual.

  • Log4j file name formatting

    I have certain logging requirements to meet, and log4j was chosen as the logging API of choice. I can do the appenders & loggers, and rolling files and all of that, however, we have requirements on how the files themselves should be named.
    ${user.home}/logging/process-name/ip-address/log.xml.{date}
    I can do the ${user.name} and append the date to the end using DailyRollingFileAppender. However, i see that when creating a logging message, you have access to a lot of data, such as the process id (or thread id), the ip address and whatnot, however, I need that information for file naming. Is this possible?
    Thank you

  • Check file name format

    1)I have to check if a file exists else terminate the job
    2)if file exists then check the format and if format is incorrect, give the message.
    i.e, i need to check whether filename is having correct format.
    for e.g: ABCDddmmyy.txt
    Every file in folder should have that format or else it should report. Any help is appreciated.

  • Per-preset file name format for external editing presets

    This would be so that you could add an identifier of the program to the filename, as in [filename]-viveza, say, if you have edited the file in that plugin. That way, you would be able to track which programs you have filtered a particular file through.

    Thanks, web-weaver and Victoria. Do you know of a reference that summarizes how much file size can be saved in compression? Are there pluses and minuses of the two compressed formats? I saw that at least one of the Nik filters (Viveza) can only use an uncompressed file if of TIFF format.
    I have done some more research on LZW vs. ZIP. http://vitaleartconservation.com/PDF/digital_image_file_formats_n_storage_v20a.pdf suggests that LZW will typically give about a 6% compression; ZIP will give more but, apparently, isn't as universal.
