What is the best aproach to achieve multiple file uploads, dynamically... which

I think the best approach is to have a button on a form which redirects to another form to add documents. Here is another link to another thread which talks about the similar issue.

Mathan, yeah.. i went thru the links whic talk about them. Finally got a solutin to have a message field which displays list of documents uploaded in conjunction with documenttable() function and the form having only one File field. Which is chained back each time he submits. This way we can rener the recent list of documents as displayed in a table.
The best part is it also gives the link to each document. :)
Thanks anyway for the suggestion.
