I want to modify journal plugin as a diary which records daily records. so that each student have 24hour time to write and edit the diary, then next day a new dairy page is opened and previous pages can't be edited. first I want to modify it to daily basis. What can i do for this
The only way you could do what you describe with the Journal plugin would be to have a new Journal activity each day, with it's 'Day's available' set for 1 days. This is due to the way the journal saves each users entry in the database. It is just ONE entry per student that grows in size each time they add to it. There is no way to limit their access to just part of their entry.
