WRITTING AN UPLOAD ROUTINE

Question

I have oracle portal but wish to write an upload routine in pl/sql and run as a link component (url link).
My procedure will do the following :-
I want the user to browse the their file system and choose a file and then upload to the portal30.wwdoc_document table. I then want to call a procedure passing the name of the file uploaded to it.
Does anybody have examples of how to do this.
I know how to upload a file using content area in portal but want a stored procedure which will be called from my poprtal app menu.
Any comments will be really helpfull.

Answer 1

I can retrieve info regarding a file that exists, that part of the code works fine, but if I execute the procedure I get the following error message:-
ORA-06550: line 2, column 1:
PLS-00306: wrong number or types of arguments in call to 'TEST_UPLOAD'
ORA-06550: line 2, column 1:
PL/SQL: Statement ignored (WWV-11230)
Failed to parse as PORTAL30 - begin
"PORTAL30"."TEST_UPLOAD";
end; (WWV-08300)
my code
p_file IN VARCHAR2)
as
begin
if p_file is null then
htp.formOpen(
curl => 'http://halifax.wira.explor.co.uk/pls/test1/test_upload',
cattributes => 'enctype="multipart/form-data"');
htp.p('<INPUT TYPE="FILE" NAME="p_file">');
htp.formSubmit;
htp.formClose;
else
htp.p('Uploaded File Information');
htp.hr;
htp.p('Name:' &#0124; &#0124; p_file);
for i in (
select *
from portal30.wwdoc_document
where name = p_file
) loop
htp.p('File Name:' &#0124; &#0124; i.filename);
htp.br;
htp.p('Size: ' &#0124; &#0124; i.doc_size);
htp.br;
htp.p('Mime Type: ' &#0124; &#0124; i.mime_type);
end loop;
end if;
end;
Question - How do I get the browse button part to work so I can upload ?
Thanks in anticipation.
