3. Using Web and Desktop tables, select only the fields that you want to see on the browser
by entering ATTACH in the table name field. Normally, the attachment name and
description will be enough, but you might want to include the attach date and time along
with the user ID of whoever attached the file. Attachment index is used internally and
never needs to be shown in the HTML. The Web Access code still accesses and updates
these fields, even though they are not included in the Desktop table or visible in the HTML.
4. Using Web and Desktop panel layouts, choose a Panel Name in which you want to
include the ATTACH table by entering the
F line command.
5. Select the ATTACH table by entering
S and position it within the other groups of fields.
Change the field description for the ATTACH table if desired. Blank out or change the
usage to
U for inquiry.
6. Finish your Desktop Panel Field List Entry and you are taken to the Desktop Table Field
Usage Definition panel. Change the field description if desired. Blank out the
create
usage
field. Attaching files is not possible in create mode. Set the
update
and
display
usage with
the desired values (
U, D, or R).
7. End the panel, file the data view record, and create the HTML using the Web
Administration page.
Other considerations
Attachments can only be viewed under Web Access. They cannot be viewed by the
traditional 3270 Information Management user and should not be included in report format
tables (RFTs).
Web Access adds the date, time, and user ID of the user attaching a file. If you would like this
information to appear in the journalized history data, you need to update data attributes
BLQ&DATA, BLQ&TIMA, and BLQ&AUSR and set cognize data to YES and journalize to
ORDER. These attributes are shipped with these settings turned off in order to avoid
generating large volumes of history data.
Do not include the data attributes for the freeform text s-words in your data view.
50
Including
those data attributes will impact performance, since the attachment text will be retrieved with
the rest of the data in the record when your data view is used. The Web Access code will
access the attachment freeform text using data view BLQATTCH when needed. The
exception to this rule is to include them when you want an attachment to appear in-line in the
HTML when displaying a record, as exemplified by showing a JPG or GIF image (such as a
person's picture) on the summary panel of the people record display. Attachment freeform
text data attribute BLQ&AT01 is included in the list of data attributes in BLQVPEOP so that
the image can be shown without the user executing a Get attachment.
General considerations
When defining tables in a data view, consider the following:
򐂰 ATTACH is a reserved table name and causes Web Access to do attachment-specific
processing of the list processor data.
򐂰 SAVESRCH is a reserved table name for saved search data. It causes Web Access to do
saved search-specific processing.
򐂰 S-words with special meaning in display-mode task HTML:
S0EF7The existence of this field in a task causes the Web Administration page to
add the code necessary to print.
50
See Table B-1 on page 158 for the data attribute names used to store attachments in freeform text.
Appendix B. Hints and tips 161
S0ED1The existence of this field in a task causes history (journal) data to be
formatted using Show_History?().
S12DE or S12DFCauses Show_Approvers?() to be added to the HTML.
S0CBCIn a change record, causes Show_Childern?() to be added.
򐂰 S-words with special meaning in update/create-mode task HTML:
S1152Causes Select_With_My_Classes?() to be added.
S0CD0In an activity in create mode, causes the field to be changed to a hidden
<input> display-only field for the parent RNID. In update or display mode, it turns into
an active link to the parent.
