hi... i would like to help me in this problem.
In the front end item edit form i want the user to fill some text box and then in the database that the K2 saves the item, in the cell of the text editor i want to save some text dependent on the text from user.
i.e
if the user write in the text box the text "John"
Then the text in the editor will be this
<div style = "width:25px;>Hi i am John<div>

The default text is this "<div style = "width:25px;>Hi i am"
and automatically added the text of the user "john".

Do you have some idea?

Hi. You need to develop a plugin for this. Of course this requires programming knowledge.
