Submit user data

I have a site that a user will submit data using a form. The form consist of a checkbox that will open a box in order to add additional information. However, additional information will need to be a new line in the database. Is this possible? I would just have them fill out a new form but they would like to copy the data from the form to make for easier user experience.

when you say new line, do you mean new column? I would think there should just be a column (or columns) for the additional data in the same row. Maybe if you can give an example…

@mattbtay the form is used for personnel to submit thier daily activites. I would like each activity to be a new entry in the database. However, each employee has mulitple daily activities each day requiring them to submit mulitple forms. Sometimes, the information may be the same or very similar, so I would like for the ability to copy past information. So my thoughts were to do 1 of 2 things.

Create a form where I have 2 submit buttons. “Submit”- normal operations or “Submit Similar” where it would submit the data but retain the information within the fields to be reused.

or

have a box expand with the same type of fields and have a check box to “copy above data”. Which if you submit it all at once it wants to either overwrite the data or you have to have muliptle columns (time, time 1, time 2) etc, which I do not want.
