Is it possible to automatically update a field with the current timestamp after I edited any other field on the row? Thanks.

Discussion and Answer

How to you compose that table?

1. If TWiki table populated by a custom template of CommentPlugin: You can add a hidden input field in the input template that contains a timestamp. Compare with EditActionItems

2. If you use the EditTablePlugin you can define a timestamp for new rows, but not when you change existing rows.

3. If you dynamically compose the table with a SEARCH that pulls topics containing a TWikiForm you can use the last update date of each topic. See TWikiForms, FormattedSearch, QuerySearch.

Yes, I am using the EditTablePlugin (second method as what you pointed out) to create the table. I have tried to use $EDITCELL{date} with a default=$date but it does not seem to work. Since I am new to twiki, I hope someone may have done this already. Thanks.

Edit Tables are great for simple use cases. For more complex queries and interactions it is better to develop a TWikiForms based application.

After done few more searches, it looks like the $EDITTABLEROW{} may work for my case. Is there any example code which can be shared with me please? Thanks.
