AddAttachment

Mon 01 January 2018

Syntax 

AddAttachment(URLDestination, DirAndFilePrefix, FileType, UserFileName[, MaxSize [, PreserveCase[, UploadPageTitle[, AllowLargeChunks]]]])

Description

Use the AddAttachment function to upload one file from an end user specified location (local storage or cloud storage) to a specified storage location. To upload more than one file with a single function call, use the MAddAttachment function.

Important! It is the responsibility of the calling PeopleCode program to store the returned file name for further use.

If a file exists at a particular place on a storage location and then another file with the same name is uploaded to that same place on that same storage location, the original file will be silently overwritten by the new file. If that is not the behavior you desire, it is recommended that you implement PeopleCode to guarantee the ultimate uniqueness of either the name of the file at its place on the storage location or the name of its place (the subdirectory) on the storage location.

You cannot use a relative path to specify the file that is to be uploaded; you must use a full path. If end users experience problems in uploading files, ensure that they browse to the file they wish to upload rather than attempting to manually enter the full path name of the file. This problem can manifest itself differently depending on the browser used. For example, with some browser versions, the PeopleSoft page appears to be in an infinite “Processing” state. Information is available on working with different browsers.

See on My Oracle Support for more information.

Additional information that is important to the use of AddAttachment can be found in the PeopleTools: PeopleCode Developer's Guide :

  • PeopleTools supports multiple types of storage locations.

    See .

  • Certain characters are illegal in file names; other characters in file names are converted during file transfer.

    See .

  • Non-ASCII file names are supported by the PeopleCode file attachment functions.

    See .

  • The PeopleCode file attachment functions do not provide text file conversions when files are attached or viewed.

    See .

  • Because AddAttachment is interactive, it is known as a “think-time” function, and is restricted from use in certain PeopleCode events.

    See .

  • Virus scanning can be performed on all files uploaded with the AddAttachment function.

Parameters

Field or Control

Definition

URLDestination

Specify the destination storage location for the file to be uploaded. This can be either a URL identifier in the form URL . URL_ID , or a string. This is where the file is transferred to.

Note: When the URLDestination parameter is specified as a string value, forward slashes (/) are required. Backward slashes (\) are not supported for a string value.

Note: Oracle recommends that you do not use a URL of the form file:// file_name with the PeopleCode file processing functions.

See .

DirAndFilePrefix

A directory and file name prefix. This is appended to the URLDestination to make up the full URL when the file is transferred to an FTP server or, when the file transferred to a database table, to make the file name unique.

Note: If the destination location is an FTP server, then it is very important whether the value passed into a call of AddAttachment for the DirAndFilePrefix parameter ends with a slash or not. If the value for the DirAndFilePrefix parameter ends with a slash, then it will be appended to the value of the URLDestination and used to indicate the relative (to the configured root directory of the FTP server) path name of the directory in which the uploaded file will be stored. If the value for the DirAndFilePrefix parameter does not end with a slash, then the portion of it prior to its right-most slash will be appended to the value of the URLDestination and used to indicate the relative (to the configured root directory of the FTP server) path name of the directory in which the uploaded file will be stored, and the portion after the right-most slash will be prepended to the name of the file that will be created at the destination.

Note: Because the DirAndFilePrefix parameter is appended to the URL, it also requires forward slashes (“/”). Backward slashes (“\”) are not supported for this parameter.

FileType

The file extension as a string. Since this parameter is required, a value must be specified; however, the value is currently ignored.

UserFileName

Returns the name of the file on the source system.

Specify UserFileName as a string variable or a field reference in the form of [ recordname .] fieldname . You must supply the recordname only if the record field and your PeopleCode program are in different record definitions.

AddAttachment returns the user-selected file name in this parameter, so its initial value is ignored and it must not be specified as a string constant.

Note: The file name for the user-selected file cannot be greater than 64 characters.

MaxSize

Specify, in kilobytes, the maximum size of the attachment.

If you specify 0, it indicates “no limit,” so any file size can be uploaded. The default value of this parameter is 0.

Note: The system cannot check the size of the file selected by the end user until that file has been uploaded to the web server.

PreserveCase

Specify a Boolean value to indicate whether the case of the extension of the file to be uploaded is preserved or not at the storage location; True , preserve the case, False , convert the file name extension to all lowercase letters.

The default value is False.

Warning! If you use the PreserveCase parameter, it is important that you use it in a consistent manner with all the relevant file-processing functions or you may encounter unexpected file-not-found errors.

Note: AddAttachment provides no indication of a conversion in the file name it returns.

UploadPageTitle

Specify a string value to be displayed in the title bar of the file attachment dialog box (as its title). This string should be simple text and contain no HTML elements. If no value is specified, the default value is “File Attachment.”

Note: In screen reader mode, the string value of the UploadPageTitle parameter is displayed in the body of the file attachment dialog box rather than as the title of the window.

Note: The parameter does not automatically handle localization issues. The string passed into the function is the exact string embedded in the page. You and your application are responsible for any translation issues.

AllowLargeChunks

Specify a Boolean value to indicate whether to allow large chunks.

If the value specified in the Maximum Attachment Chunk Size field on the PeopleTools Options page is larger than is allowed for retrieval, then the system breaks the file upload into the largest sized chunks allowed. If AllowLargeChunks is set to True, this behavior can be overridden so that it is possible for an end user to upload a file in chunks that are too large for the system to retrieve. If AllowLargeChunks is set to False, the system will use the largest size chunk that is allowed for retrieval, or the configured chunk size, whichever is smaller.

Note: If the chunks are too big to be retrieved, then any file retrieval built-in function, such as GetAttachment, will fail.

Note: The AllowLargeChunks parameter is only applicable when the storage location is a database record. It has no impact when the storage location is an FTP site or an HTTP repository, since attachments at those locations are never chunked.

See

This is an optional parameter.

The default value is False.

Returns

You can check for either an integer or a constant value:

Numeric Value

Description

0

%Attachment_Success

File was transferred successfully.

1

%Attachment_Failed

File transfer failed due to unspecified error.

The following are some possible situations where %Attachment_Failed could be returned:

  • Failed to initialize the process due to some internal error.

  • Failed due to unexpected or bad reply from server.

  • Failed to allocate memory due to some internal error.

  • Failed due to timeout.

  • Failed due to non-availability of space on FTP server.

  • Failed to close SSL connection.

    If the HTTP repository resides on a PeopleSoft web server, then you can configure tracing on the web server to report additional error details.

    See .
